FOR OK RE ACK Reports in this issue are for week ending June 30, unless otherwise indicated. - 590 - WEATHER BUREAU 30-DAY OUTLOOK JULY 1961 The Weather Bureau's 30-day outlook for July calls for temperatures to average below seasonal normals in the Southeast and Pacific Northwest. In the remainder of the country above normal temperatures are indicated, with greatest departures in the Central States. Rainfall is expected to exceed normal in the Southeast, Northwest, and Southern Rocky Mountain States. Subnormal amounts are predicted over the rest of the Nation. Weather forecast given here is based on the official 30-day "Resume and Outlook", published twice a month by the Weather Bureau.

WEATHER OF THE WEEK ENDING JULY 3 This week was cooler than last week in most of the Far West, and a little warmer in the central and eastern portions of the country. Average temperatures for the week in the Far West ranged from slightly above normal in southern areas to a few degrees below normal in the Pacific Northwest, where maximum temperatures were down in the 70's and 80's the latter part of the week and minima below freezing were reported by a few stations in Oregon east of the Cascades. East of the Rockies, weekly average tempertures ranged from 6° to 9° above normal in the northern Great Plains to 3° to 6° below normal in the lower Mississippi Valley and much of the Southeast. Maximum temperatures in the northern Great Plains ranged in the high 90's to over 100° during the first part of the week when Rapid City, South Dakota, reported its highest June temperature, 106°. Precipitation was heavy in the Atlantic coastal States, except Maine, and also in the middle and upper Mississippi Basin. Weekly amounts were again very light in most of the Far West. The week's rainfall in Florida, generally totaling 1 to over 3 inches, further replenished soil moisture in that State, but 1 to over 2 inches in the Carolinas left soils too wet to work. Most rain in the Northeast occurred on July 2 during the passage of a cold front. Violent thunderstorms, some with damaging winds and hail, were set off in New England and several local tornadoes were reported. Also, lightning was responsible for many fires and widespread power failures. Most rain in the middle Mississippi Valley occurred during thunderstorm activity at midweek and during the passage of a cold front at the end. Thunderstorm activity was widespread in Arizona late in the week and some stations reported 1 or 2 inches of moisture. In the extreme upper portions of the Mississippi Valley and Great Plains, good showers were widely scattered and most of the area continues very dry. A high forest fire hazard was reported in Minnesota. Drought continued in Utah and Nevada where rainfall was limited to a few isolated thunderstorms. (Summary supplied by U. S. Weather Bureau). - 591 - CEREAL AND FORAGE INSECTS GRASSHOPPERS - INDIANA - Nymphs abundant in many areas; populations in fence rows, roadsides and similar areas ranged to highs of 30 nymphs per square yard.

DC 2 a A i a Eg A 2 a 2 OE EK 2K WEATHER OF THE WEEK ENDING JULY 11 The week was abnormally warm in the northern Great Plains, and unseasonably cool elsewhere. Showers occurred over nearly all the country in the course of the week, but were light and widely scattered in much of the Far West and northern Great Plains. The week was unusually cool from the upper Mississippi Valley to the Appalachians where average temperatures were as much as 10° below normal. In extreme northern sections minimum temperatures on the 4th, 5th, 6th, and 7th ranged in the 30's and 40's, and were the lowest of record for those dates at numerous stations. Some unusually low temperatures included 37° at Duluth, Minnesota, and Marquette, Michigan; 32° at Breed, Wisconsin; and a record low of 46° for July at Charleston, West Virginia. In much of the Southeast below normal temperatures have persisted since the middle of June. In the northern Great Plains temperatures for the week generally averaged from 3° to 6° above normal. Maximum temperatures rose to over 100° at a number of stations in this region at the beginning of the period, but ranged in the 80's and 90's during the remainder of the week. Precipitation occurred in widely scattered thunderstorms in North Dakota, but amounts were generally too light to furnish much relief from the drought. This was also true in eastern Montana. Some good rains, however, fell in northeastern Wyoming and the western third of South Dakota. Rainfall in other areas of the Rockies, extremely variable, was generally adequate. Rains are needed in southern portions of Indiana and Illinois, and in some areas of western Tennessee, and west-central Florida. Wind, hail, and lightning damage occurred in eastern Iowa on the 4th and 5th, and lightning caused numerous fires and power failures in central Massachusetts and northern Connecticut on the 9th. Rather general showers and lower temperatures occurred in the Far West early in the week. In Utah and Nevada these showers were heavy enough to furnish temporary drought relief in scattered areas. In Arizona showers occurred mostly in the mountains and amounts were under 3/4 inch. In New Mexico showers at the beginning and last few days of the week brought 1 to over 2 inches of moisture to north-central portions and 1/10 to 1/2 inch to the remainder of the State. At Albuquerque, New Mexico, 1.63 inches of rain fell in 1 hour on the 8th, a new record there. (Summary supplied by U. S. Weather Bureau). =! 61'9);— CEREAL AND FORAGE INSECTS GRASSHOPPERS - MARYLAND - Nymphs of Melanoplus spp. averaged 2-5 per sweep on alfalfa in Howard and Queen Annes Counties. (U. Md., Ent. Dept.). INDIANA - Melanoplus spp. unusually abundant in fence rows and other grassy areas throughout most of State; scattered reports of crop damage. (Lehker, Matthew).

Melanoplus differentialis dominant species. (Munson, Thomas, Wood). WISCONSIN - Damage evident, but not severe, in an Adams County cloverfield infested by M. bivittatus and M. bilituratus nymphs. Two alfalfa fields in Marquette County had counts of 40 M. femurrubrum nymphs per square yard. Hatching underway generally. (Wis. Ins. Sur.). MINNESOTA - Approaching maturity in many areas; some dispersal occurred in west central and northwest districts. (Minn. Ins. Rpt.). NORTH DAKOTA - Cropland: Adult dispersal through field crops now common in many localities. Severe damage to small grains reported in 13 counties. Controls still being applied in most sections to protect crops. Nymphs of M. femurrubrum increased in southeast. Rangeland: Cooperative Federal, State and rancher control programs underway in McKenzie County area, southwest section; and in Richland and Ransom County areas, southeast section. Completion of these programs expected next week. (N. D. Ins. Sur.). SOUTH DAKOTA - Continue serious in many areas; threatening to severe in northwest, north central and central areas.

PREDATORS - UTAH - Various species have largely controlled severe spirea aphid infestations in Logan, Brigham and Ogden. (Knowlton). MISCELLANEOUS INSECTS JAPANESE BEETLE (Popillia japonica) - Adults beginning to emerge in MASSACHUSETTS. (Crop Pest Cont. Mess.). First adults of season in RHODE ISLAND observed in Cranston, Smithfield and Warwick. (Mathewson). Adult emergence increasing in NEW JERSEY. (Ins.-Dis. Newsl., July 3). Trapping and visual survey in mountain counties of NORTH CAROLINA, from Ashe to Cherokee, indicate general but light emergence. Heavy emergence in Ashe, Watauga, Henderson, Transylvania and eastern Swain Counties anticipated. Personnel have been assigned to handle produce move- ment, especially beans, from markets at Hendersonville, Boone and West Jefferson. Adults present generally in Piedmont counties; no unusually high populations - 640 - recorded. Peak emergence has passed in eastern Coastal counties. Unexpected high populations occurring in some sections of Robeson and Sampson Counties. Minor feeding on crops, such as tobacco and soybeans, reported. Immediate con- trols by farmers have prevented any crop damage. The Cherokee Indian Reservation, near Tennessee State Line, will be treated in areas where populations are observed, Trapping in SOUTH CAROLINA completed in area generally south of Columbia; traps moved to northern portion of State, lower and upper Piedmont counties. Very light infestation at Latta only new point discovered so far. Guided by presence of adults, peak emergence has passed in lower half of State. Infestation again pre- sent at Bennettsville, but is light and with no appreciable extension over that of 1960. This is also true of small infestations at Dillon and Florence. Infesta- tion at Columbia, along Congaree River, appears to be expanding and populations are becoming heavier. No change noted in infestation in Aiken County. Traps being retained along highway 301 at truck and tourist stops and at airports at Florence, Columbia and Charleston to detect escaping adults. All counties north of Columbia being trapped; early reports indicate light emergence occurring in upper Piedmont counties. (Kelley, PPC). Trapping continues throughout TENNESSEE, with negative reports from all but eastern section. Emergence is so heavy within treated area of Loudon County that foliage treatments have been applied to reduce populations. In all other areas, treatments appear to be satisfactory. In Loudon County, treatments were not completed until very late winter and may be reason for heavy emergence. Outside treated area in Loudon County, infestation has now been extended to include approximately 8,700 acres. In John Sevier Rail- road yards, north of Knoxville, known infestation has been extended to include approximately 1,000 acres. Single adults were trapped in Fountain City, Knox County, and in Chattanooga, Hamilton County; 2 adults have been trapped in Newport, just outside treated area. No adults have been trapped in or near treated areas, other than in Loudon County. (Landrum, PPC). No adults were trapped in FLORIDA during the period July 2-7. (Jeffrey, PPC). Trapping began at major air terminals in OREGON on June 13, with all collections negative to July 7. (Capizzi). In CALIFORNIA, adult populations dropped abruptly after June 21; no live adults taken by visual survey or in traps since June 30. Regular application of controls being made at 10-day intervals in Sacramento; street trees treated at night due to daytime vehicle parking. Trap placement continues; 2,365 traps operating in Sacramento area. Quarantine proclamations have been adopted by California Depart- ment of Agriculture, restricting movement of hazardous materials from known infested area in Sacramento. (Cal. Coop. Rpt.).

Also in North Dakota, dominant, high populations of CLEAR-WINGED GRASSHOPPER (Camnula pellucida) causing severe crop damage in many communities along the Canadian border; this is first recorded economic crop damage by this species in North Dakota in many years. Locally heavy grasshopper infestations continue to cause some concern in northwest Oklahoma and infestations continue to cause considerable crop damage in areas of central and west central Texas. All rangeland in Asotin County, Washington, and scattered rangeland in 4 other Washington counties, heavily infested by grasshoppers; infestations also building up in many areas of Oregon. (pp. 651, 652). Heavy first-generation EUROPEAN CORN BORER infestations indicated in Cass County, ' North Dakota, and 75 percent of corn plants damaged in areas of Iowa during week ending July 8. First-generation European corn borer infestations in Arkansas heaviest in many years. (pp. 652, 653). Heavy CORN EARWORM infestations reported in areas of Alabama, Texas and Oklahoma; and heavy infestations of CORN ROOTWORMS continue in Nebraska and lodged as high as 75 percent of corn plants in some spots in Kansas.

FOR ROKK WEATHER OF THE WEEK ENDING JULY 17 The week's weather was abnormally cool and showery east of the Continental Divide, and hot and dry in the Far West. East of the Continental Divide temperatures for the week averaged from 3° to 6° below normal, except near to slightly above normal in the Florida Peninsula and extreme upper Great Lakes region. This is the second consecutive cooler than normal week in the Midwest and Northeast and the fifth in most of the Southeast. In the northern Great Plains, this was the first abnormally cool week in the last three in eastern portions and the first since the latter part of May in western sections. Weekly average temperatures were 6° above normal in much of the Pacific Northwest and as much as 9° above in interior portions of California. Maximum temperatures ranged in the high 90's to over 100° in Washington and much of Oregon during the middle of the week, and in Idaho and Utah on Saturday. Frequent widespread showers east of the Rockies were very beneficial in the drought areas of the northern Great Plains and upper Mississippi Valley. Showers from the 10th through the 15th produced much-above-normal amounts in Minnesota except the southeast portion, with weekly totals ranging up to 3.38 inches at Tracy. All portions of North Dakota received light to moderate moisture, with heaviest amounts in the northeast where Petersburg measured 3.94 inches. South Dakota reported amounts generally ranging from 0.25 to 1.00 inch and 2.00 inches locally in the extreme southwest; topsoil remained short in most of the State, however. In eastern Montana, rainfall was light in most areas and soil moisture continued short. Scattered showers on several days in Wisconsin and Michigan were very beneficial. Rainfall was unusually heavy in much of the South where soil moisture is generally ample to surplus. Weekly totals of 4 to 6 inches were numerous in the upper and middle coastal sections of Texas and 2 to 3 inches in central and southeastern sections of the State. Fulton, Arkansas, reported 12.27 inches for the week. Weekly totals ranged from 1 to 9 inches in Mississippi. Dry, hot weather in the Far West continued the severe drought in much of the Great Basin area. Much more rain is needed in northern Nevada where last week's rains furnished temporary relief. In Idaho, ranges are dry and stock water supplies are critically short in some areas. Washington and Oregon now report high forest Weather continued on page 676. - 651 - CEREAL AND FORAGE INSECTS GRASSHOPPERS - MICHIGAN - Normal numbers of Melanoplus femurrubrum present at Charlevoix, Boyne City and Rogers City. (Huteon)- ILLINOIS = Melanoplus spp. varied 60-540 per 100 sweeps in grassy roadsides in west and west-southwest districts; an occasional adult M. bilituratus observed. In clover and alfalfa in west and west-southwest districts, Melanoplus nymphs averaged 30 per 100 sweeps; also migrating into soybeans in few places. Grasshoppers becoming evident in localized areas throughout State. (111. Ins.Rpt.). MISSOURI - Small nymphs, mainly M. differentialis, still present in hatching areas in southwest.

Grasshopper development advanced more than normal in northwestern section; major cropland species now mostly adults. Dominant species include M. bivittatus, M. bilituratus and Camnula pellucida. Hatch of M. femurrubrum now appears near completion with nymphs averaging third instar in development. Population counts of grasshoppers average 15-28 per square yard, but range 100-200 per square yard in some fields. Most infestations now occur throughout fields as marginal forage generally nonexistant. Infestations in many soil bank lands low because drought-reduced food supplies have been exhausted. Dominant, high populations of C. pellucida causing severe crop damage in many communities along Canadian border; ane is first recorded economic crop damage by this species in many years.

Before departing from area, planes\will be checked and if conditions necessitate, will be treated. (Bennett, PPC). Adults becoming abundant generally in PENNSYLVANIA and beginning to feed on various hosts. (Pepper). Adults have been present for 7-10 days in Ettrick area of Chesterfield County, VIRGINIA; infestation originally light, but numbers appear to be increasing. (Edwards, July 5). Several active adults noted at a home near Sparta, Caroline County, Virginia, on July 7. (Tarpley). First adult of season for Watauga County, NORTH CAROLINA, was found June 21 (Muldner, PPC); several farmers in Sampson County reported heavy adult feeding on weeds on June 30 (Morgan, PPC). Visual inspection, trapping and public assistance continue in Sacramento area of CALIFRONIA. Two adults were taken July 7 and 10; one in West Sacramento, Yolo County, approximately 1.5 miles from known infestation in Sacramento; other adult was taken 12 blocks east and 3 blocks north of known infestation still in City of Sacramento. Controls being applied at regular intervals in a 300-block area; traps have been placed in most of Sacramento-Yolo County area included in program. Approximately 2,900 traps currently in opera- talon (Callin COOD AER DitEp Ee NORTHERN MASKED CHAFER (Cyclocephala borealis) - MARYLAND - Adults numerous at lights during first 2 weeks of July at several localities in Prince Georges County.

FE HCE 2k I Ie 2K 2 KE 2K 2K KE WEATHER BUREAU 30-DAY OUTLOOK MID-JULY TO MID-AUGUST 1961 The Weather Bureau's 30-day outlook for the period from mid-July to mid-August calls for temperatures to average below seasonal normal between the Appalachian and Rocky Mountains with greatest departures in the Central Plains. Above normal temperatures are indicated in extreme portions of the Northeast, Southeast, and Southwest, with near normal elsewhere. Rainfall is expected to exceed normal in most parts of the country lying between the Rocky and Appalachian Mountains. Subnormal amounts are predicted west of the Continental Divide and along the South Atlantic Coast. In regions not specified near normal amounts are in prospect. Weather forecast given here is based on the official 30-day ''Resume and Outlook", published twice a month by the Weather Bureau.

WEATHER OF THE WEEK ENDING JULY 24 Typical midsummer weather prevailed across the Nation this week - hot, dry and sunny in the Far West, showery and humid with mild temperatures east of the Rockies, Temperatures averaged 3° to-locally 6° below normal from the Dakotas to Texas, and in the upper Mississippi Valley, and about normal east of the Mississippi except well above in New York and New England, and much above in coastal areas from Norfolk, Virginia, to Atlantic City, New Jersey. Afternoon temperatures in the 80's generally prevailed in northern areas, except that highs in the 90's reached the Dakotas the first day of the period and southern portions of New York and New England at the end. This was the warmest week of the summer to date in the Northeast. Showers and thunderstorms, widespread and occurring on 2 to 4 days east of the Rockies, furnished generally ample moisture for crops which made rapid growth. Rainfall totaling from 1 to over 2 inches in Upper Michigan, Wisconsin, Minnesota and the eastern half of North Dakota greatly benefited grain crops and helped replenish short soil moisture. Showers were very light in the western Dakotas and eastern Montana where soil moisture continues very short. Scattered flash floods and many severe local storms were reported. One of the worst flash floods occurred in the vicinity of Charleston, West Virginia, where more than a score of lives were lost. Tornadoes were reported in central Indiana and Illinois on the 21st, and in the latter State again on the 23d. Severe wind and hail left a belt of damage from Norton to Rice Counties in central Kansas on the 19th. In the Far West, afternoon temperatures generally ranged in the 80's in the central and upper Rocky Mountain regions and along the Pacific Coast, and in the 90's to over 100° elsewhere. Rainfall was generally limited to a few light, scattered showers west of the Continental Divide, except for some showers of 1 to 2 inches in Arizona. In most of the Pacific Northwest a high fire hazard exists in the forests and rangelands. (Summary supplied by U. S. Weather Bureau). - 679 - CEREAL AND FORAGE INSECTS GRASSHOPPERS - ILLINOIS - Nymphs of Melanoplus spp. ranged 2-10 per square yard on clover and alfalfa and 2-20 per square yard on grassy roadsides in southern area. (111. Ins. Rpt.). MISSOURI - High populations of very small nymphs still observed in hatching areas. Counts ranged 3-35 per square yard in fence rows and wastelands; dominant species M. differentialis. (Munson, Thomas, Wood). IOWA - Grasshoppers becoming numerous enough to require controls in Dallas, Marion, Washington and Jefferson Counties. (lowa Ins. Inf., July 17). WISCONSIN - Grass- hoppers range 3-45 per yard (average 15) in Marinette, Green Lake and Columbia Counties. Averaged 10 per yard in Winnebago, Dodge and Washington Counties. Hatching continuing in many fields surveyed. Second and third instars of M. femurrubrum predominate. In northern Walworth and Waukesha Counties, M. femurrubrum averaged 30 per square yard (mostly first to third instars); controls recommended. (Wis. Ins. Sur.). MINNESOTA - Most infestations of economic importance still widely scattered and localized, except in southern Hubbard and northern Ottertail Counties where high populations found in large areas, primarily soil bank land; dominant species M. bivittatus, M. bilituratus and Camnula pellucida. Heavy hatch of M. femurrubrum occurred during past two weeks in north- west, west central, central and southwestern districts. Most trouble spots in soil bank land, roadsides and wasteland, but many alfalfa fields in western area have high M. femurrubrum populations which range up to 80 per square yard; controls may be advised. (Minn. Ins. Rpt.). NORTH DAKOTA - Severe grasshopper infestations common in most southwestern counties. Cropland infestations present in Dunn, McKenzie and Golden Valley Counties. Elsewhere, infestations scattered but Widespread. Infestations generally fieldwide. However, recent rains improved roadside vegetation which continues to support high populations in many sections. Controls continued in most areas to protect threatened crops. Some small grains treated several times and may require additional treatments before harvest. Damage to small grains, although present in many communities, appears less severe than in northwestern area. Advanced crop development and later grasshopper hatch believed responsible for this condition. Some grasshoppers invading corn fields. This migration expected to increase rapidly in most sections and severe damage to corn anticipated if not treated. Grasshopper development ranges from newly hatched nymphs to adults; extreme variation exists between areas. High populations of M. femurrubrum nymphs observed along some roadsides, soil bank fields and scattered alfalfa fields where hay has been removed. Dominant species include M. bivittatus, M. bilituratus, M. femurrubrum, C. pellucida and M.packardii. Few M. differentialis nymphs observed in Bowman, Adams and Grant Counties. Several reports of aerial migrations reported in Adams and Hettinger Counties. Survey in north central area shows scattered but widespread severe infestations present in most counties. Infestations general in Sheridan, McLean, Ward, McHenry and Ramsey Counties. Severe marginal damage evident in most areas. Complete leaf defoliation apparent in many wheat and barley fields. Some boll clipping in flax observed. (N. D. Ins. Sur.). SOUTH DAKOTA - Grasshoppers continue serious in many areas of State. Threatening to severe conditions exist in areas of northwest, north central, south central and central sections of State. Most infestations spotty and not extensive. Severe infestations observed in parts of Sully and Potter Counties; grasshoppers moved into and damaged some small grains and moving into corn; considerable controls being applied. Some movement out of soil bank and other uncultivated croplands into croplands and gardens reported on Lower Brule Indian Reservation in Lyman County. Spotty infestations present in western Lawrence, Shannon, Haakon, eastern Meade and northwestern Fall River Counties. Threatening to severe conditions exist in northwestern corner of Mellette County; harvesting of small grains reduced hazard, but corn and cane fields being damaged; some treatments applied. Road ditches, soil bank land and other uncultivated croplands in northwestern Mellette County quite heavily infested, with other parts of county having light to threatening populations; dominant species M. bivittatus, with M. bilituratus, M. femurrubrum and M. packardii also present. Red mites parasitizing some grasshoppers in northwestern Mellette County. (Hanten). OKLAHOMA - Marginal damage to crops by several grasshopper species continued quite common in most areas of State, particularly in western half.

Coop. Sur.). ARKANSAS - Heavily infested pasture area of Benton County for past two years; averaged 15-20 per square yard along field margins on orchardgrass. Dominant species M. differentialis; mostly nymphs. (Ark. Ins. Sur.). LOUISIANA - Moderate infestations of M. differentialis present on railroad embankments, along ditchbanks and around field margins in northwest area. (Newsom, Cancienne). WYOMING - Several grasshopper species averaged 9 per square yard on rangeland over Crook County; part of Weston County and scattered areas of Niobrara and Goshen Counties also infested. (Fullerton). UTAH - Grasshopper nymphs numerous on farms and roadsides at Huntsville and Eden, Weber County; 10 percent adults in Nephi-Levan area in Juab County; and C. pellucida and Melanoplus spp. moderately numerous at Panguitch in Garfield County. Knowlton, July 14). Outbreak con- spicuous in many areas from Fayetteville, Sanpete County, to Nephi, Juab County; many C. pellucida, M. bilituratus, M. packardii and some M. bivittatus winged in various localities. At least 65,000 acres of dryland wheat, pinto beans and range- land severely infested by grasshoppers in area surrounding and east of Monticello, San Juan County. Dominant species Aulocara elliotti, M. bilituratus, M. packardii and M. bivittatus. A number of additional species involved. Grasshoppers severely damaged range and pastureland on 1,200 acres of Uintah and 2,500 acres of Grand County; several species damaging at Randolette in Uintah County and C. pellucida infesting 2,000 acres in Neola-Hayden area. (Knowlton). NEVADA - Oedaleonotus enigma averaged up to 30 per square yard in crested wheatgrass and 4-10 per square yard in previously burned rangeland in Orovada area, Humboldt County.

Wireworm Populations During 1960-61 (Fall to Spring) Season and Their Damage to Potatoes in Vicinity of Charleston, South Carolina, During Spring of 1961 - SOUTHERN POTATO WIREWORM (Conoderus falli) was only elaterid found in significant numbers in soil in cultivated fields during the period. Populations varied 1.2-12.6 and averaged 3.9 larvae per square foot in top 6 inches of soil in 20 untreated fields on 9 farms during November and early December 1960. At least sixteen 6- cubic-inch soil samples from each field were screened. Soil samples from 2 potato fields that had not received insecticide treatments showed populations of 2.9 and 5 larvae per square foot in March and April 1961. An average of 17.6 percent, by weight, of potatoes harvested from 5 fields not treated for wireworm control showed some degree of wireworm injury. An average of 3.9 percent of tubers from these fields showed wireworm damage as defined by market standards; proportion on injured potatoes ranged 2.5-40 percent and that of damaged ones 0.9-12 percent. Examination of some 1,066 shipping point inspection certificates issued to potato growers or shippers in Charleston area during June 1961 showed that 0.3 percent of potato lots inspected had wireworm damage (as defined in U. S. Market Standards for Potatoes) in excess of the 6 percent tolerance, by weight, allowed for all external damage in case of U. S. Grade No. 1. Damage ranged 3-6 percent in 4 percent of lots and 1.5-2.9 percent in 25 percent of lots. Majority of local growers apparently made insecticide applications for wireworm control and in most cases adequate protection of potato crop against an average wireworm population was obtained, inasmuch as only 0.3 percent of inspected lots were ineligible to Grade 1 because of wireworm damage alone and only 4.3 percent showed damage of 3 percent or more.

HAWAIIAN INSECT NOTES The following reports were submitted by the Hawaiian Entomological Society and were abstracted from the "Notes and Exhibitions" in the minutes of the July 10, 1961, meeting. A REDUVIID (Scadra rufidens) - A specimen collected at Manoa is the third collected in the State since the species was first reported in December 1958. The fourth Hawaiian record was captured flying in bright sunlight in Wailupe Valley, Oahu. @. E. Hardy, J. W. Beardsley). A 4-year-old girl in Aina Haina, Oahu, was bitten on the finger of her left hand by an ARACHNID (Cheiracanthium diversum). The child experienced immediate severe pain, which spread rapidly until the whole arm was involved. A doctor treated her for the pain, which subsided after approximately 3 hours; however, consider- , able swelling remained in the hand. As far as is known, the girl is not known to be allergic to arthropod stings or bites, although it was reported that members of her family are supposedly allergic to stings of bees and wasps. (D. E. Hardy). A NOCTUID (Platysenta illecta) - This determination was received from Dr. E. L. Todd of the U. S. Nation Museum, for the recently established noctuid tentatively determined as Peregia illecta. Identity was confirmed by Dr. Todd and Mr. D. S. Fletcher of the British Museum (Natural History). (J.

DEAE FC AK OK A A Ee 2 2K RE = TAO = INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES LARGE PINE WEEVIL (Hylobius abietis (L.)) Economic Importance: This weevil is generally considered to be one of the most important forest pests in Europe. Pock-marking Damage to Pine It has increased in importance as a pest of young conifers in many parts of Europe since World War II as a result of large- scale felling and replanting of pine and spruce. The pest breeds in stumps and the adults damage living trees by gnawing the bark. Feeding on the succulent portions beneath the young bark and in the cambial layer by the adults can cause serious damage. Irregular holes are cut into the young stems, the lower part being damaged the most. In severe cases the whole stem becomes pock-marked. The attack persists from early spring until late summer in Britain, with a peak in numbers being reached in midsummer when new adults of the latest brood emerge. Feeding generally subsides when the weather is cold or wet. Injured trees are preferred, but when adults are abundant they readily attack uninjured trees. Epidemic numbers of this weevil occur commonly in forest areas of Britain and in Europe. Hosts: The weevil will attack all conifers and many hardwoods including oak, birch and sycamore. Scotch pine and Douglas-fir are two of the favorite host plants in Britain. General Distribution of Hylobius abietis (L.) Curculionidae, Coleoptera No. 136 of Series = 7108) = Distribution: Occurs throughout most of Europe and through Siberia in the USSR to Korea and Japan. Life History and Habits: The biology as recorded in Britain is as follows: Adults overwinter in the soil just below the surface or, when the weather is colder, at deeper levels. Activity in the spring is dependent on the temperature; it begins January and February in the South and in April in the northern districts. Peak activity is reached from mid-May to mid-July in the South, followed by a tapering off period until activity ceases altogether in September. The adults are long-lived. Those that emerge first in the spring are mostly one or more seasons old. Those that appear later are adults preparing to breed for the first time or those that are just leaving their pupal cells after overwintering as larvae. Newly emerged adults feed on bark of fallen stems or branches until their reproductive organs reach maturity. Eggs are deposited on stumps and roots of coniferous trees either below or just above the soil level. Hatching takes place in 2-3 weeks and young larvae burrow longitudinal tunnels in the roots or branches. The larvae remain in the tunnel until the following summer when pupation takes place. Adult emergence takes place 3 weeks after pupation. Feeding by the new adults proceeds actively in warm weather and mating takes place if weather conditions permit. If not, the adults hibernate in the stumps or soil. Description: ADULT - Length 8-14 mm. General color: Piceous, with patches of yellow hairs. Snout broad and coarsely punctured. Antennae inserted at apex of snout. Prothorax nearly as broad as long, sides rounded, narrowed in front, coarsely punctured. Patches of yellow hairs on sides and behind, near scutellum. Elytra parallel-sided, tapering markedly just near apex. Striae with well-marked chains of punctures, especially in center. Interstices broad and roughly punctured. Yellowish hairs present in small, isolated patches and also in 2 irregular transverse bands. Larger patches also present near apex. Legs black or piceous, femora armed with a strong tooth.

FO RIC AR ARC KK WEATHER BUREAU 30-DAY OUTLOOK AUGUST 1961 The Weather Bureau's 30-day outlook for August calls for temperatures to average above seasonal normals from the Northern and Central Rocky Mountain States westward to the Pacific Coast and also in the Southeast. Below normal temperatures are indicated in the northeast quarter of the Nation and in the Far Southwest, with near normal elsewhere. Rainfall is expected to exceed normal in the Northeast, Ohio Valley, and Lower Lakes. Subnormal amounts are predicted for the Southeast, Southern Plains, and Northern Rocky Mountain States. In areas not specified near normal amounts are anticipated. Weather forecast given here is based on the official 30-day "Resume and Outlook", published twice a month by the Weather Bureau.

WEATHER OF THE WEEK ENDING JULY 31 Typical midsummer weather prevailed across the country this week. Afternoon temperatures generally ranged in the 60's and 70's along the Pacific coast, in the 80's in the northeastern quarter of the Nation, and in the 90's elsewhere except mostly in the 100's in southwestern desert areas. In the eastern half of the Nation, frequent thundershowers furnished generally adequate moisture for crops, but in the western half showers were widely scattered and mostly light. High humidity prevailed in the East on several days, and in the North Central States near the end of the week. In the northern Great Plains and upper Mississippi Valley, scattered showers that became widespread during the middle and latter parts of the period furnished much beneficial moisture for the second consecutive week. Wisconsin now reports soil moisture mostly adequate. Rainfall in Minnesota generally ranged from 3/4 to over 2 inches in the southern two-thirds of the State, but under 1/4 inch in the north. Numerous stations in North Dakota reported 1 to 1 1/2 inches of rain, and weekly totals in South Dakota generally ranged from 1/2 to 1 1/2 inches except under 1/4 inch in some extreme western sections. In Wyoming, some good showers fell in the eastern half of the State and along the northern border.

C. Volume 11 August 11, 1961 Number 32 COOPERATIVE ECONOMIC INSECT REPORT Highlights of Insect Conditions GRASSHOPPER adult surveys underway or completed in a number of States. Heavy concentrations appeared in numerous Conservation Reserve lands throughout Idaho; threatening populations present on over 100,000 acres in Harney County, Oregon; serious situation exists on over 285,000 acres in various areas of Utah; populations moderate on 33,000 acres in panhandle of Oklahoma; and infestations continue troublesome in several areas of North and South Dakota. RED-LEGGED GRASSHOPPER populations high in alfalfa in several Minnesota districts and definitely a threat to forage crops in Wisconsin. Migratory. flights of MIGRATORY GRASSHOPPER observed in Idaho and North Dakota. (pp. 743, 764). Second-brood EUROPEAN CORN BORER laying eggs in Kansas, Iowa and New York. (p. 744). FALL ARMYWORM infestations reported in Missouri, Maryland and Pennsylvania. (p. 745). CORN ROOTWORM adults reported abundant in areas of Wisconsin and Nebraska. (pp. 745, 746). CORN LEAF APHID continues to increase on corn in a number of states. (pp. 746, 747). RED HARVESTER ANT infestations much heavier in pastures in Lincoln County, Oklahoma, than in past several years. (p. 747). THREE-CORNERED ALFALFA HOPPER continues damaging to alfalfa in Arizona and Texas and high populations present in areas of Nevada. LYGUS BUGS abundant enough in alfalfa to require controls in Jackson County, Oregon; continued high on same crop in Arizona; and ranged 30-45 per sweep on alfalfa in areas of Clark and Nye Counties, lez aa) POTATO LEAFHOPPER is a definite threat to forage crops in Wisconsin. p. 748). JAPANESE BEETLE damaged cereal and forage crops in Maryland and Delaware and injury to apple trees noted in Ohio. Also reported damaging grapes in Spartanburg and Greenville Counties, South Carolina, and ornamentals in Onondaga County, New York. (pp. 746, 750, 760). CITRUS INSECT situation reported in Florida; TEXAS CITRUS MITE infestations remain more numerous and widespread than in prior years. Goa 52))- BOLL WEEVIL populations increasing rapidly due to emergence of second generation in eastern Texas. Increases also reported in Oklahoma, Arkansas, Tennessee, Alabama, Georgia and South Carolina. Controls will be needed in most areas to protect the crop. (p. 755, 756). BOLLWORMS remain light in most states, but economic infestations reported in areas of New Mexico, Texas and Oklahoma. Infestations will probably increase, however, and treatments may be needed. Fields should be closely checked. (p. 756). SPIDER MITES increasing in cotton in areas of Texas, Arkansas, Tennessee and Alabama. LYGUS BUGS heavy in untreated cotton in Arizona and controls warranted in several southern Eddy County, New Mexico, fields. (p. 757). FALL WEBWORM and ELM LEAF BEETLE continue damaging in several states. (pp. 758, 759). BAGWORM infestations damaging in areas of Oklahoma, Missouri, Nebraska, Indiana and South Carolina. (p. 759).

HORN FLY continues to be of considerable annoyance to cattle in Utah, New Mexico, Texas and Vermont, SCREW-WORM remains fairly heavy and active throughout Texas. (p. 762). ADDITIONAL NOTES (Idaho, Michigan, Vermont). (pp. 764, 765). INSECT DETECTION: Face fly recorded for first time in Wyoming and several new county records reported in South Carolina, Georgia, Kansas, South Dakota and Nebraska. (p. 761). A May beetle (Phyllophaga affabilis) recorded for first time - 742 - Highlights - continued in Iowa (p. 764) and mimosa webworm recorded for first time in Montgomery County, Indiana (p. 760). Reports in this issue are for week ending August 4 unless otherwise indicated. FOI OR OR IRE AC OE I A IE AIR A OR IR A IC IK ok 2k 2 WEATHER FOR THE WEEK ENDING AUGUST 7 Extreme heat from the Cascade Mountains to the northern Great Plains was the only particularly abnormal feature of the week, as typical midsummer weather prevailed in most of the remainder of the Nation for the second consecutive week. Daily maximum temperatures ranged in the high 90's to well over 100° from the Cascades to the Dakotas. The past week was one of the hottest on record in Montana, where a few stations reported alltime high temperatures and several others reported record highs for August. The high temperatures also rose to record levels for August in Idaho and northeastern Oregon. Even the nights were unusually hot in the northern Great Plains where minima occasionally were in the mid-70's. Temperatures for the week averaged slightly below normal in the lower Great Plains and from the upper Mississippi Valley eastward, except well below along the New England coast. The passage of three cold air masses across New England during the week kept temperatures below normal there continuously, and were responsible for unusually cool nights on August 1 and 2 when minima in the 30's and 40's occurred in low spots and valleys. Temperatures for the week averaged normal to slightly above in the Southeast. Scattered areas of thundershowers, which occurred across the country each day, again furnished generally adequate moisture for crops in the central and lower Great Plains and from the Mississippi Valley eastward. Weekly totals were extremely variable, ranging from none at all up to several inches. Rains of 1 to 2 inches fell in mountainous areas of Colorado, Arizona and northern and western New Mexico. Thunderstorms on several days in Utah and Nevada furnished moderate to heavy rainfall in some areas. No appreciable rain fell in Oregon, where lightning started a number of forest fires. (Summary supplied by U.S. Weather Bureau). - 743 - CEREAL AND FORAGE INSECTS GRASSHOPPERS — OREGON - Melanoplus bilituratus caused severe damage to an alfalfa- field near Crane, Harney County; populations over 25 per square yard in margins and 10-12 per square yard in field, Controls necessary to prevent total loss of crop. An extensive infestation, primarily Camnula pellucida, exists in Harney County from Burns south into Malheur Lake Bird Refuge. Although exact extent of infestation not defined as of August 2, grasshoppers uniformly present in threaten- ing proportions over all meadow and rangeland surveyed during late July and early August. In egg beds, populations in excess of 100 per square yard not uncommon. Considerable egg laying occurred prior to August 2. Preliminary estimates of threatening populations are 75,000 to 80,000 acres on Malheur Refuge and 28,500 acres outside of it, but within the county. Several hundred acres of barley near Lawen severely damaged by C. pellucida. (Capizzi). NEVADA - Second and third instars of Melanoplus sp. averaged 14 per sweep in several alfalfa fields north- west of Las Vegas and Virgin Valley areas, Clark County. (Bechtel, Parker). UTAH - Grasshopper situation serious in several large areas of State, including infestations which cover more than 100,000 acres in western Box Elder County; more than 75,000 acres in Levan Ridge area of Juab County and extending into northern Sanpete County, including Flat Valley; 35,000 acres in Cedar Valley area of Utah County; 70,000 acres in San Juan County; 1,500 acres of C. pellucida infested area in Hayden-Neola area of Uintah Basin; 3,000 acres of “hot spots" in Cedar Breaks area of Iron County; and 500 acres along Podunk Creek south of Bryce in Kane County. (Thornley, Knowlton). COLORADO - C. pellucida populations up to 40 per square yard on rangeland in areas where concentrated egg laying in Archuleta and San Miguel Counties. (Hantsbarger). NEW MEXICO - Heavy, spotted infestations of grasshoppers in rangeland areas northwest of Lovington, Lea County. (N. M. Coop. Rpt.). OKLAHOMA - Adult grasshopper surveys continue in panhandle and northwestern counties. In western panhandle, 12,000 acres of range considered moderately infested as are 22,000 acres of nonrange type habitats. Aulocara elliotti predominates the former, while M. bivittatus dominates the latter. Farther east in Woodward and Major Counties, 20,000 acres of range lightly infested and 12,000 acres of roadsides, crop rows and margins moderately infested. Ageneotettix deorum dominant species in range and M. bivittatus dominant in crop habitats. (Okla. Coop. Sur.). SOUTH DAKOTA - Grasshoppers remain a problem in parts of central and western areas. Chemical controls being used in central area, mainly for protection of corn. Rangeland survey completed in Harding, Perkins and Butte Counties; no infestations found in Perkins County, but much of cropland lightly infested. Noneconomic infestations reported in Belle Fourche irrigation project. (Burge).- NORTH DAKOTA - Cropland: Infestations noneconomic to threatening in northeast. Infested areas scattered and confined generally to Red River Valley counties; M. bivittatus and M. bilituratus dominant species. C. pellucida and M. femurrubrum represented high percentage of populations at several stops. About 75 percent of population adults; however, second and third instars of dominant species still present in many communities. Rangeland: Adult survey in McKenzie County showed threatening range infestations in 8,000 acres west of Grassy Butte and southeast of Cartwright. Light infestations generally through other range areas in county. Heavy aerial migration of M. bilituratus observed near Cartwight; moving with a northwest wind toward southeast. Scattered severe infestations of C. pellucida observed in northwestern Dunn and northeastern McKenzie Counties. WW. D. Ins. Sur., Wilson). MINNESOTA - Grasshopper dispersal general in north- western, north central, west central and central districts. Some damage to margins of small grain fields noted. High counts of M. femurrubrum found in alfalfa in southeast, south central, southwes:, west central and central districts. (Minn. Ins. Rpt.). WISCONSIN - Grasshoppers definitely a threat to forage crops; treat-— ments and cutting of alfalfa recommended. First, second and third instars found in profusion in alfalfa and other crops and along roadsides in many sections of State. Counts per square yard, primarily M. femurrubrum, averaged 15 in Pepin, Trempealeau, St. Croix and La Crosse Counties; 25 in field in Green County; and 60 in field in Grant County. Average for latter two counties closer to 15 per square yard. Average of 20 per square yard observed in eastern Iowa, Sauk and northern Dane Counties. (Wis. Ins. Sur.). MISSOURI - Grasshoppers moderately high in areas scattered throughout State. Counts in improved pastures in southwest ranged 12-18 per square - 744 - yard.

Percent of infested plants less than 25; usually 4-16 percent. (Burkhardt). MISSOURI - Second-brood infestations not observed in northeast; light first brood in same area has been further diluted due to uniform development of corn. (Munson, Thomas, Wood). ILLINOIS - First-generation populations in northern one-half of State about the same as those of 1960. See map for counts per 100 stalks. Lower figures are for 1961; upper figures for 1960. (I11.

Highest counts averaged about 20 per plant; several fields had 6-12 per plant. Few larvae and pupae still present in soil. Distended females indicate oviposition underway. Most corn past stage ‘where clipping will affect: pollination. (Burkhardt). IOWA - In corn field in Audubon County, adults 90 percent this species and 10 percent D. undecimpunctata howardi and D. virgifera, Failures of soil insecticides to control rootworms reported in the area; rotation in which corn is grown only 2 years in succession in any field may be recommended in the future.

ADDITIONAL NOTES IDAHO - Adults of a MELYRID (Collops sp.) common and general in potato fields throughout Fremont and Blaine Counties. (Portman). High populations of a PSYLLID (Psyllopsis fraxinicola) found on blue ash trees at Twin Falls and Moscow determined as this species by L. M. Russell. Detected primarily because of copius quantities of honeydew being produced. (Gibson). BANKS GRASS MITE (Oligonychus pratensis) present on most roadside grasses examined throughout Fremont County and on older leaves of all varieties of forage grasses in experimental plots at Twin Falls. (Portman). CARROT BEETLE (Bothynus gibbosus) particularly abundant in Arena Valley on August 1; adults ranged 1-3 per square yard. (Waters). Second-generation CODLING MOTH (Carpocapsa pomonella) larvae entered fruit in Emmett area July 26. (Scott). Populations of COLORADO POTATO BEETLE (Leptinotarsa decemlineata) very scattered throughout 300 acres in Blaine County and spotted infestations in Minidoka and Fremont Counties. (Portman). All stages of DOUGLAS-FIR TUSSOCK MOTH (Hemerocampa pseudotsugata) present on blue spruce and white fir in and adjacent to Moscow. Females now emerging and eggs already deposited, although small and full-grown larvae still being found. Infestation confined entirely to blue spruce and white fir, even though Douglas-fir is adjacent to these hosts. Rather heavy infestation found in forested areas of Boundary County, 7 miles north of Bonners Ferry. Aerial survey being conducted by Forest Service. These infestations, and infestations reported in nearby Canada may indicate future buildup of this pest in central areas of Pacific Northwest. (Manis, Portman, Johnson). Adult GRASSHOPPER survey begun during last week of July showed that heavy concentrations have appeared in numerous Conservation Reserve lands throughout State, consisting principally of Melanoplus bilituratus, M. bivittatus and M. packardii. Several thousand marginal acres Of these lands treated to prevent migration to spring wheat. M. bivittatus averaged 50 per square yard on field of spring wheat adjacent to this land; heavy egg deposition occurring in some areas. Many Conservation Reserve fields treated on margins for 150-300 yards into area; controls excellent. As entire area not treated, average of 9-15 per square yard still remain in most cases. Approximately 10,000 acres of Conservation Reserve and roadside area heavily infested in Fremont County. Grasshoppers continue a problem in Lewiston area, Nez Perce County, with up to 35-40 per square yard, principally M, bilituratus and M. bivittatus. Light, high flight of grasshoppers believed to be principally M. bilituratus, observed July 20 drifting east from top of Horseshoe Bend grade to 3 miles of Banks. Some controls applied in Fairfield area, Camas County, on July 21 to control movement from Conservation Reserve lands into wheat fields, but so late that populations spread over much greater area. Grasshopper populations 5-50 per square yard in Camas Reservoir area, Elmore County, and, in some cases, 125 per square yard in Camas Meadow area; mating and egg laying occurring. Approximately 6,000 acres heavily infested. In Stanley Creek Basin area, Custer County, where experimental controls were applied, - 765 = many grasshoppers were killed but Camnula pellucida populations remain 7-9 per square yard over most of area; grasshoppers have spread from meadow areas along hillside, and cover an estimated 150-2,000 acres. Grasshoppers also a problem on Conservation Reserve land in Clark County; some damage occurring to crested wheat-— grass in Conservation Reserve lands. A new locality record was made for Pedioscirtetes nevadensis on range south of Heart Mountain between Grouse and Meyers Creeks on Crooked Creek drainage in Clark County, by Mr. Nonini. This is approximately 35 miles across a mountain range from area where species occurred in outbreak numbers in 1950 at Blue Dome. Bruneria sordida, Aulocara elliotti, M. packardii and P. nevadensis averaged 3-4 per square yard on sparse range grasses, with significant damage. (Evans, Nonini). GREEN PEACH APHID (Myzus persicae) populations very low on potatoes at Tetonia Branch Experiment Station, Teton County, with individuals difficult to find. Population patterns in Fremont County seed potato field much the same as in previous years with heaviest infestations in fields nearest town of Ashton and decreasing in direct proportion to distance from town. Infestations developing primarily from infested home vegetables and flower gardens within Ashton. (Portman). LYGUS BUGS (Lygus spp.) range 1-10 per sweep in seed fields treated 2 weeks earlier near Parma. (Waters). A FLOWER BUG (Orius tristicolor) ranged 2-40 per red clover stem near Parma and was responsible for low clover aphid population. (Waters).

(Nonini). PEA APHID (Macrosiphum pisi) populations in alfalfa in Minidoka County below expected average for year; practically nil in northern part of State; and extremely low in Nez Perce, Clearwater and Latah Counties; predators were very abundant. (Portman, Halfhill). SPIDER MITES (Tetranychus spp.) becoming numerous in many legume fields in southwest, requiring immediate treatment for seed production. (Waters). YELLOW-NECKED CATERPILLAR (Datana ministra) attacking shade and orchard trees in Parma area. Pest is apparently more abundant than during previous 5 years. (Scott). MICHIGAN - Larvae of TIGER SWALLOWTAIL (Papilio glaucus) observed in Covert and Grand Rapids and summer-brood adults of SMALLER EUROPEAN ELM BARK BEETLE (Scolytus multistriatus) increasing rapidly and constructing brood galleries in East Lansing and Grand Rapids. Few ZIMMERMAN PINE MOTH (Dioryctria zimmermani) adults began to appear at St. Charles and Augusta. ELM SCURFY SCALE (Chionaspis americana) crawlers very noticeable and well established on elm at East Lansing, Howell, Detroit, Monroe and Grand Rapids. Galls of POPLAR VAGABOND APHID (Mordwilkoja vagabunda) extremely numerous on eastern poplar at Lansing, East Lansing, Eaton Rapids and Howell. SIX-SPOTTED LEAFHOPPER (Macrosteles fascifrons) populations not as numerous as would have been anticipated from early collections at Stockbridge, Howell, Bath, East Lansing and Hudsonville. Summer-generation adults of CODLING MOTH (Carpocapsa pomonella) began to emerge at Traverse City on August 1.

Reports in this issue are for week ending August 11, unless otherwise indicated. - 770 - WEATHER OF THE WEEK ENDING AUGUST 14 The most noteworthy feature of the weather during the week was the replacement of above-normal warmth and high humidities by unseasonably cool, dry Canadian air over northern and middle sections of the country from the Rockies to the Atlantic coast. Surges of very cool, dry air began spreading Slowing southeastward and eastward from western Canada on Wednesday, the 9th, reaching the Oklahoma area and Ohio Valley by Friday and the Atlantic coast by Sunday. Afternoon temperatures on Wednesday were in the upper 90's in the Dakotas, near 90° in the Lake region, and had reached the 90's in sections of New York and New England. The afternoon temperatures dropped to the 70's and low 80's by Thursday in the northern Great Plains, by Friday and Saturday in the Lake region, and by Sunday in the North Atlantic States. Some of the lowest morning temperatures were 32° at Warroad, Minnesota, on the 12th; and 35° at Alpena, Michigan, 34° at Saranac Lake, New York, and 31° at Norfolk, Connecticut, on the 14th. By the weekend, however, an eastward moving trend to warm weather had set in over the northern Great Plains. Afternoon temperature readings continued in the 90's to over 100° in the valleys of the Pacific States, from 100° to over 110° in the far southwestern desert areas, and in the mid-90's to over 100° in central and southwestern Texas. Temperatures for the week averaged mostly near normal to about 5° above normal in the Atlantic States and west of the Continental Divide, and below normal by about the same amount from the eastern slope of the Rockies eastward to the Appalachians and Georgia. Precipitation was heavy in sections on eastern Arizona, western and northern New Mexico, parts of Colorado and Wyoming, and quite generally from the central Great Plains eastward to the middle and southern Appalachian region. Amounts were heavy also in Gulf coastal areas. Elsewhere rains were generally light to moderate. Mostly dry weather persisted in the droughty sections of the northern Great Plains and in the hot, dry Far West where the fire hazard is moderate to severe. A number of lightning-set fires were reported from the forests and rangelands of the Pacific States, Idaho, and western Montana. A total of 11 inches of rain was reported from southeast of Washta, Iowa, on the 8th and 9th; up to 2 inches in the southern mountains of California; over 4 inches in about 3 hours in the northeastern section of Albuquerque, New Mexico, on the llth; 4 to 5 inches locally in northeastern Oklahoma and adjacent areas on the 13th, in southwestern Illinois on the 10th and 11th, and in sections of West Virginia on the llth and 12th. These heavy rains produced local flooding and caused some damage. (Summary supplied by U.S. Weather Bureau). =- 771 = CEREAL AND FORAGE INSECTS GRASSHOPPERS - OREGON - Controls applied to 9,733 acres of alpine meadow in north- east Baker County, July 27-30; species involved, Melanoplus borealis, Bradynotes sp., probably deplanata, and Melanoplus sp.

(Fitchett). SOUTH DAKOTA - Adult survey completed in some northwestern counties. Range survey shows infestation very light in northern part of Ziebach County except along Moreau River. Several rangeland areas infested in southern part of county; largest area (20,000 acres) has up to 14 grasshoppers per square yard. Survey in cropland shows threatening to severe infestations in parts of Hughes, Sully, Potter, Walworth and Campbell Counties with M. bivittatus and M. differentialis dominant. Control continues for crop protection. (Burge). Severe on 3,200 acres in southeast Beadle County. (Mast). Threatening conditions exist in small areas around Eureka, McPherson County, and near Beebe and Loyalton, Edmunds County; M. bivittatus, M. bilituratus, M. differentialis dominant species. (Hanten). MINNESOTA - Grasshopper development in northern part of State about one week ahead of southern counties. Most early hatch species in northern area in adult stage. Some field margin damage to corn and soybeans in west central and northwest districts. Grasshoppers dispersing from hatching areas in these 2 areas. Few scattered fields in Watonwan and Rock Counties have high populations, mainly M. femurrubrum; counts ranged 20-36 per square yard. (Minn. Ins. Rpt.). WISCONSIN - Counts range 0-3 per square yard in all but one of northern tier of counties; ranged 3-12 per square yard in Douglas County.

M. femurrubrum in these areas ranged fourth to fifth instars. Averaged about 12 per square yard in Marquette, Waushara, Portage, Waupaca, Outagamie and Shawano Counties. M. femurrubrum averaged 15 per square yard in southeast counties, with counts of 25-30 not uncommon. One field in northern Walworth County had an estimated 5 per stem with plants nearly one-third defoliated. Some injury noticeable on soybeans and corn in southeast; grasshoppers range first to third instars. (Wis. Ins. Sur.). IOWA - Concern increasing throughout southern half of State; counts range 20-30 third stage nymphs to adults per square yard in fence rows and field margins although weather hot and humid.

Rpt.). MISSOURI - Ranged 4-20 per square yard in roadside, fencerow and wasteland areas in northwest; O-7 per square yard in cropland areas. Ranged 0-15 per square yard in idleland areas in southwest; some damage to leaves of late grain sorghum observed. Mainly M. differentialis in both areas. (Munson, Thomas, Wood). EUROPEAN CORN BORER (Ostrinia nubilalis) - OKLAHOMA - In Payne County, one stalk infested of 108 examined; 6 larvae and one pupa present. (Okla. Coop. Sur.). NEBRASKA - Larvae in Cuming County averaged 3,829.5 per acre and 4,249.1 in Hall County; 40.4 percent of stalks in Cuming County infested with average of 31 per 100 stalks and 34.7 percent of stalks infested with average of 27.2 borers per 100 stalks in Hall County. (Hill, Webb). SOUTH DAKOTA - Larval development ranged third to fifth instar in northeast. (Hanten). MINNESOTA - Light second-generation emergence occurred in southern counties. No egg masses observed, but few first- stage larvae found in one south central field. Peak moth emergence should occur in approximately 2 weeks. Number of borers per infested stalk appears higher than usual; borer counts per 100 stalks approximately same as in 1960, except higher in west central district. (Minn. Ins. Rpt.). WISCONSIN - Second generation underway in most southern counties. Trap catches indicate moths emerging at relatively fast rate. Pupation 14 percent at Arlington, 15 near Plainfield and 5 in Walworth County. Infestation varies generally with age of corn; 40 percent infestation observed in field of sweet corn near Hancock although damage generally lighter. One field of corn near Tomah averaged 3 first-generation borers per plant; such fields present high potential for second generation. (Wis. Ins. Sur.). IOWA - Development at Ankeny 16 percent fifth-stage larvae, 32 percent pupae, 52 percent emerged; egg masses 23 per 100 plants on early corn and 58 on late corn. (Iowa Ins. Inf. , Aug. 7).

Above normal temperatures are indicated from the Upper Mississippi Valley westward to the Pacific Coast, with near normal elsewhere. Rainfall is expected to exceed normal in most of the southern half of the Nation, and also in the Northern Plateau and coastal areas of New England. Subnormal amounts are indicated for the Central Lakes Region, the Upper Mississippi Valley, and Northern Plains. In areas not specified, near normal precipitation is anticipated. Weather forecast given here is based on the official 30-day ''Resume and Outlook", published twice a month by the Weather Bureau.

WEATHER OF THE WEEK ENDING AUGUST 21 Cool Canadian air and showers kept temperatures at seasonal to much below normal levels during most of the week over the eastern portion of the country, central and southern Great Plains, and southwestern Interior. In spite of scattered showers, however, temperatures rose into the 90's and occasionally into the 100's in the Far West and on a few days in the northwestern Great Plains area. Fair, sunny weather generally prevailed during much of the week over the northern and central Interior and nearly all week in the eastern portion of the country, as the cool, Canadian air moved slowly eastward from over this region to the Atlantic Ocean. A Pacific depression, accompanied by showers in a narrow north-south band across the country, moved eastward over the Pacific States on the 14th and 15th, and in conjunction with a cold front passed over the Great Plains on the 17th and 18th, and to the north Atlantic coast by Sunday night, the 20th. Meanwhile, a low pressure area moved from the east Gulf on Saturday, the 19th, northward along the Atlantic coast to Maine by Tuesday morning, the 22d. The general rains produced by this storm in the Atlantic States were badly needed in most areas. The week was warmer than usual along the Pacific coast and eastward across the northern Rockies, Dakotas, and Minnesota, and cool for the season elsewhere. The departures ranged from about 6° above normal in northern Idaho, parts of Montana, and extreme western Dakotas to about the same amount below normal in Oklahoma, southern Kansas, and sections of Arkansas, Tennessee, Georgia, and the Carolinas. Precipitation was generally light to moderate in the Far West, northern Great Plains, north-central Mississippi Valley, and from Tennessee northward to Canada. Heavy amounts were reported from parts of Arizona and New Mexico and from northwestern Texas north-northeastward over the east-central Great Plains to Minnesota and in Arkansas and the Atlantic and Gulf States. Lightning started numerous grass and forest fires in the Far West, although showers helped to control them. Hailstorms occurred in many areas, with one in west-central Lower Michigan on the 15th causing crop damage of $1 to $2 million. (Summary supplied by U. S. Weather Bureau). - 793 - CEREAL AND FORAGE INSECTS GRASSHOPPERS - WASHINGTON - Infestations of 8 or more per square yard on 75,000 acres in Douglas County, 23,000 acres in Lincoln County and 25,000 acres in Stevens County.

(Reports in this issue are for week ending August 25 unless otherwise indicated.) - 816 - WEATHER OF THE WEEK ENDING AUGUST 28 Frequent light to heavy showers fell almost daily over the eastern quarter of the Nation, especially in the Atlantic States, unti] late Saturday. Otherwise, mostly sunny weather prevailed over the country during the week, with showers in most areas on a day or two. The week was quite cool in the central and southern por- tions of the country east of the Rockies until late in the period when afternoon temperatures rose to near or into the 90's over the eastern two-thirds of the country, except in eastern Canadian Border and mountainous areas. Temperatures rose daily into the 90's and occasionally the 100's nearly all week in the northern Great Plains and during the first and middle of the week in the Far West. Temperatures averaged warmer than usual in the Far West, along the middle Canadian Border, and in the Northeast. These weekly averages were below normal from east- ern Nebraska and southern portions of Minnesota, Wisconsin, and Michigan southward to the Rio Grande Valley and Gulf and south Atlantic coasts. The departures ranged from more than 9° above normal in central and eastern Montana to about the same amount below in the northeastern Texas-western Arkansas area. Precipitation was heavy in the Atlantic States, sections of the Middle Gulf States, in the Tennessee area, the eastern Nebraska-western Iowa area, and the Lower Lake region. Elsewhere amounts were mostly light to moderate, with none in most of Texas and a few sections of the Great Plains. Griffin, Georgia, reported a total of 8.89 inches for the week; Towson Police Station, Maryland, 6.30 inches; Wash- ington, D. C., 5.17 inches; and Caribou, Maine, 3.60 inches. Rainfall in excess of 12 inches in 24 hours on the 26th and 27th in eastern and central Puerto Rico produced severe flooding with the loss of several lives and property and crop damages that may reach millions of dollars.

A NITIDULID (Conotelus mexicanus) - A specimen was collected in Kapulehu Forest Reserve, March 24, 1961,at 1,980 feet by L. W. Quate. Although this is the second record from Hawaii, it is reported now because of its potential damage to local crops. This pollen-feeding species was first recorded from Oahu, Kauai and Maui in 1955. Det. by Amy Suehiro. (L. W. Quate). A DELPHACID (Chloriona kolophon) - Female specimens were collected in June 1961, in a light trap at Waipio, Oahu, but positive identification was not made until males were obtained in July. About a dozen specimens have been collected in light traps at Waipio and Ewa, Oahu,and 4 adults were collected sweeping grass (Eleusine indica) in an alfalfa field at Ewa. This is apparently a grass feeding species. First report for State according to ARS records. Det. by J. W. Beardsley. A GELECHIID (Dichomeris sp.) - Larvae and adults found at Ewa, Oahu, during July when species damaged alfalfa. This is a widespread genus containing several species of economic importance. Det. by J. F. G. Clarke. A light infestation of CITRUS MEALYBUG (Pseudococcus citri) found on sugarcane at Ewa, Oahu. Although reported on sugarcane in other parts of the world, this is the first record on this host in Hawaii as far as is known. The mealybugs were in small colonies on the leaves at the juncture of the leaf sheath and leaf blade and were being tended by the ARGENTINE ANT (Iridomyrmex humilis). (J. W. Beardsely).

Volume 11 September 8, 1961 Number 36 COOPERATIVE ECONOMIC INSECT REPORT Highlights of Insect Conditions CORN EARWORM larvae increased significantly in sweet and field corn in Maryland and larvae 3-18 per head in grain sorghum heads in Burleson and Brazos Counties, Texas. Infestations appear generally light in most areas, however. FALL ARMYWORM infestations becoming common in alfalfa and grain sorghum in several areas of Oklahoma and becoming more common in late corn in all sections of Maryland. (p. 841). SORGHUM WEBWORM infestations spotty, but rather heavy in some areas of Brazos and Burleson Counties, Texas, and SORGHUM MIDGE adult activity reported in Lubbock area of Texas and Payne County area of Oklahoma. NORTHERN CORN ROOTWORM infestation in New York considered economic (previously not considered a pest in the State).

Below normal temperatures are predicted west of the Continental Divide except for above normal in coastal California. Precipitation is expected to exceed normal over the Midwest and Pacific Northwest. Subnormal amounts are indicated for the Northeast, Middle Atlantic States, Gulf Coast, and Far Southwest, with near normal elsewhere. Weather forecast given here is based on the official 30-day ''Resume and Outlook", published twice a month by the Weather Bureau.

WEATHER OF THE WEEK ENDING SEPTEMBER 4, 1961 Hot, humid weather prevailed east of Texas and the Great Lakes where rainfall, mostly from thundershowers, ranged from none up to several inches. In the remainder of the Nation, hot weather ended with a sharp temperature drop and scattered showers with snow at some higher elevations during the latter part of the week. Some places in the Northeast had their warmest week of 1961. Nights were unusually hot in northern New England and New York where lowest temperatures generally were in the 60's and 70's. Daytime temperatures generally ranged in the 90's. Temperatures for the week averaged from 6 to 12° above normal from the upper Mississippi Valley eastward. A high of 94° was recorded at Marquette, Michigan, on August 30. The weather was unusually hot in the northern Great Plains and upper Mississippi Valley the first part of the week, only to be followed by a sharp, cold snap over the weekend. Several stations in North Dakota reported 104° at mid-week but Williston and Minot had their first snowfall of the season on Saturday and the temperature fell to 31° at Carson on Sunday. In South Dakota, temperatures ranged up to 105° early in the week but over the weekend Aberdeen reported a low of 30° with frost in susceptible places. Low temperatures in the 30's were reported as far south as the Texas Panhandle over the weekend. In the Far West, unseasonably cool weather came early in the week and weekly average temperatures generally ranged from 3 to 6° below normal in the lower Rocky Mountain Region. In much of the Far West this week was also 3 to 5° cooler than the previous week and in some areas as much:as 10°. In parts of Idaho the temperature dropped as much as 30° during the week. Beneficial rains came with the cold weather in much of the Far West, lessening the fire hazard and benefiting ranges. This was particularly true in the drought stricken states of Utah and Nevada where flash floods resulted from local down pours. Snow fell in the Rockies from Wyoming to New Mexico. This early season snow was unusually heavy in Colorado where Denver reported earliest snowfall on record on September 3 and many vacationers were stranded in the mountains over the holiday weekend. In California, precipitation was very light and the fire hazard continued serious as fires burned over many thousands of acres during the week. In agricultural areas of Alaska, precipitation was much below normal with only 0.08 inch at Anchorage. Daytime highs in the low 60's were about normal for both the Anchorage and Fairbanks areas but lows averaging in the upper 30's were about 4° below normal in the Fairbanks area. Indian-summer type weather prevailed in the Matanuska Valley. Harvest of fine quality commercial vegetables continues to meet demands. Tropical storm Carla, believed to have reached hurricane force during the night, was centered about 200 miles south of extreme western Cuba at 8 a.m. e.s.t., September 6, and was expected to continue moving northward with hurricane winds likely over western Cuba, Wednesday night and Thursday.

HE IC AE 2 OR i a i 2 2 2k a 2 2 2 2k ek Reports in this issue are for week ending September 8 unless otherwise indicated. - 860 - WEATHER OF THE WEEK ENDING SEPTEMBER 11 Hurricane Carla, with sustained winds exceeding 100 m.p.h., near the center and of hurricane speed (74 m.p.h., and over) outward for 100 miles, lashed the Texas coast for many hours. The eye of the storm crossed the coast in the Matagorda Bay area between Corpus Christi and Galveston during the afternoon of September 11. Carla's approach was preceded by the mass evacuation of an estimated 300,000 persons from danger zones along the coasts of Texas and Louisiana. This well-executed exodus has held loss of life to a minimum in this very extensive and severe hurricane. The hurricane spawned a number of tornadoes which resulted in the loss of at least one life, numerous injuries, and severe localized structural damage. General havoc was wrought by high winds, excessive rainfall, high tides, and inundation by sea water as the hurricane moved inland. Much of the region affected comprised a rich agricultural region and as a result, a large percentage of the loss consisted of damage to crops. For the second consecutive week unseasonally hot, humid weather prevailed east of the Great Plains, with the hottest weather relative to normal east of the upper Mississippi River where temperatures for the week averaged as much as 10° above normal. Maximum temperatures ranged in the 80's and 90's and minimum temperatures in the 60's and 70's, except in the extreme North where minima were generally in the 50's and 60's. Temperatures averaged near normal in the Great Plains, with considerable variation during the week. In the northern Great Plains the week began cool with frost in the Nebraska Panhandle on the Sth, after which rising temperatures through Saturday exceeded 100° at some stations, only to be followed by a sharp drop on Sunday. In the Far West, the week was slightly cooler than normal, except unusually cool in New Mexico and Colorado, with near record lows for the season reported in the latter State at the beginning of the period. In Utah, frost at higher elevations damaged some corn and beans. Precipitation, produced by thunderstorms, was spotty from the Rocky Mountains to the Atlantic coast, but generally adequate in most areas to maintain satisfactory soil moisture. Moderate to heavy rains fell in Montana, North Dakota, and the northern two-thirds of Minnesota on the 9th and 10th. Moderate to heavy rainfall west of the Continental Divide was mostly limited to eastern Idaho, southern Utah, and parts of Arizona, most of it falling about midweek. In the Pacific States and Nevada, the week was extremely dry, with most stations reporting no rain at all. (Summary supplied by U. S. Weather Bureau). - 861 - CEREAL AND FORAGE INSECTS GRASSHOPPERS - IDAHO - Adult populations generally light in Bonneville, Bannock, Power and Oneida Counties week ending August 18; some light damage observed.

S. Forest Service Introduction: For the past two years, California has experienced heavy losses in timber due to BARK BEETLES. The most critical of these has been in areas suffering from moisture deficiency during the spring months. The spring pre- cipitation picture for the State as a whole for 1961 is quite variable, ranging from more than 100 percent of normal in Eureka to about 30 percent of normal in San Diego. In most cases the seasonal precipitation follows about the same pattern as that presented by the spring period. Taking all known factors into consideration, the outlook for forest insect problems for the fall and winter (1961- 1962) appear as follows: The overall outlook for the State indicates that losses from BARK BEETLES will be generally light in the north coast area, moderate in the northeastern portion of the State, heavy in the central and southern Sierra and very heavy in southern California. Losses on burns, particularly those which occurred two years ago, are expected to show a marked increase. Lightning-struck trees, particularly ponderosa pine, are expected to create an additional insect hazard in all areas where early summer electrical storms were prevalent. North Coast Zone: This includes the northwestern counties from Mendocino, Lake and Glenn Counties north to Siskiyou County. No major change in insect activity is expected in this area by the major forest insects over the zone as a whole. Some scattered, local outbreaks of WESTERN PINE BEETLE (Dendroctonus brevicomis) are expected in the lower-elevation fringe pine type. Some increase in Melanophila drummondi and DOUGLAS-FIR BEETLE (Dendroctonus pseudotsugae) in Douglas-fir will probably occur. Losses are expected to increase on the two-year-old burns. Northeastern California Zone: This zone includes the Cascades and Sierra Nevada Ranges from eastern Siskiyou.and Modoc Counties south to Plumas County. No major change in insect activity is expected in this zone as a whole. WESTERN PINE BEETLE is expected to remain at about the same level as last year, with scattered losses continuing at a moderate to high level in eastside stands. Some increases are expected locally in trees struck by lightning in the early summer storms. Ips spp. activity is expected to decrease over last year. FIR ENGRAVER (Scolytus ventralis) will probably continue at its present high level over the zone as a whole. Activity of JEFFREY PINE BEETLE (Dendroctonus jeffreyi) and MOUNTAIN PINE BEETLE (Dendroctonus monticolae) will continue at about the same as for last year. Some increase of CALIFORNIA FLATHEADED BORER (Melanophila californica) and M. drummondi may occur. SPRUCE BUDWORM (Choristoneura fumiferana) activity is expected to be slightly downward. Insect activity around the major burns is is expected to increase over last year. Central and Southern Sierra Zone: This zone includes the Sierra Nevada Range from Sierra County south to Kern County, Inyo and Mono Counties, and embraces the Yosemite and Sequoia-Kings Canyon National Parks. Insect activity in the northern areas and in the Mother Lode country may decrease, but epidemic losses in the southern part of the Sierra Nevada Range will probably continue. Ips spp. activity is expected to be less than last year, particularly in the northern part and in the Mother Lode. WESTERN PINE BEETLE will cause less damage in the northern portion of the zone, but will continue to cause high losses in the southern part. FIR ENGRAVER is expected to be at a high level over the whole zone, but not to the extreme high level of last year. JEFFERY PINE BEETLE is expected to continue at a relatively high level in local areas. The MOUNTAIN PINE BEETLE situation will probably not change. The situation concerning a PINE REPRODUCTION WEEVIL (Cylindrocopturus eatoni) may improve, particularly in - 877 - natural stands. In Douglas-fir, Melanophila drummondi is expected to remain at a high level in a few local areas, but with some improvement expected. Insect activity around the major burns is expected to increase over last year. Southern California Zone: This includes the forested areas south of the Tehachapi Mountains and in the Coast Range south of Monterey Bay. The insect situation in southern California will reach an alltime high in areas where no control action is taken. The maintenance control action that has been underway for the last four years in southern California should keep losses stabilized in all areas under maintenance control. The insects involved in this zone include WESTERN PINE BEETLE, Ips spp., JEFFREY PINE BEETLE, FIR ENGRAVER, MOUNTAIN PINE BEETLE and CALIFORNIA FLATHEADED BORER. There are no important timber burns in southern California. FR I I aK aK Change of Generic Name for Field Crickets As a result of research in systematics and comparative behavior at the University of Michigan (Ann Arbor) and MacDonald College (Montreal, Canada) , American field crickets which for several years have been placed in the genus Acheta are now referred to the genus Gryllus (Jobin, L. J. and Bigelow, S. 1961. Canad. Ent. 93(4):313, footnote.). Gryllus was the traditional generic assignment for these crickets prior to a preliminary division of the genus (in a broad sense) that occurred some years ago. The house cricket, domesticus (L.), remains in Acheta, as it is generically distinct from the field crickets. Seven species of Gryllus currently are recognized in the eastern United States, but, without information relating to the songs or other aspects of bionomics, species identifications sometimes are practically impossible. Only preliminary information on the species inhabiting the western half of the United States is available, although work based on the latest methods is under way. (A. B.

GOLDEN NEMATODE (Heterodera rostochiensig Wall.) in soil with plants destined for Califernia at San Pedro, California, iC) INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES FLEA BEETLES (Chaetocnema spp.) Economic Importance: Although the genus Chaetocnema is well represented in the United States, several additional species have been recorded as important pests in various parts of Europe, Asia and North Africa. The four species and one subspecies that are more frequently mentioned in the ees are C. concinna (Marsh.), C. tibialis tibialis (111.), C. tibialis breviuscula (Fald. 5 Cc. aridula (Gyll.) and C. hortensis (Geoffr.). The first three have been recorded as serious pests of sugar beets while the latter two are injurious to cereal crops and various grasses. Of the two that attack cereal crops, C. hortensis appears to be more widespread, but C. aridula is probably the more important since it attacks both oats and barley while the former lives chiefly on barley. Wheat is rarely attacked by either species. All of the species and subspecies that attack sugar beets are considered important in areas where they occur. C. t. tibialis is very injurious in southern France where it is abundant and C. t. breviuscula has been reported as the most important pest of sugar beets in the USSR. C. concinna replaces C. t. tibialis in northern Europe and, in addition to sugar beets, is a serious pest of several other crops which include rhubarb, buckwheat and mangold. Figure I. Chaetocnema aridula larval damage to stalks of oats Damage to grain crops is caused primarily by the larvae. Growth of infested plants is slow; the central leaf becomes yellowish and sometimes the terminal buds die. Excessive tillering of infested plants occurs and yields are often-times considerably reduced. Damage is most frequently noted on the margins of fields. Damage to sugar beets is caused primarily by the adults; however, larvae of C. t. breviuscula have been recorded as feeding on beet roots while larvae of C. tibialis and C. concinna develop in roots of Chenopodiaceae and Polygonaceae, respectively. Adult feeding on young sugar beets can be severe, sometimes destroying the crop. Distribution: C. aridula and C. hortensis occur throughout all of Europe and east to Asia; C. hortensis also occurs in North Africa. C. concinna occurs throughout most of Europe and east into Siberia, but is largely replaced by Go 185 tibialis in the southern areas of western Europe. C. tibialis is found in all of Mediterranean Europe, Turkey, Iraq, United Arab Republic (Egypt), southern USSR (including Turkestan) and the Ryukyu Islands (Asia) (the subspecies C. t. tibialis occurs in the west and C. t. breviuscula in the eastern part of the species distribution). Hosts: C. aridula and C. hortensis have been recorded on a number of grasses and small grains including oats, barley, wheat and rye; however, oats and barley appear to be the most important. Adults of C. concinna, C. t. tibialis andC. t. breviuscula may be found feeding on a number “of hosts, but the most economic — damage occurs to sugar beets. Adults of C. concinna have also been recorded damaging buckwheat, strawberry, kale, hops, rhubarb, hemp, dullseed cornbind, ——————— (Chrysomelidae, Coleoptera) No. 137 of Series - 880 - lambsquarter goosefoot, Rumex spp., mangold and a number of other plants; and C. t. tibialis adults have also been recorded on barley, mustard, soybean, rippleseed plantain and all plants of the Salsolaceae. Life History and Habits: The biology of C. aridula and C. hortensis is quite Similar. Adults appear during May in France. Eggs are deposited toward the base of young grain or grass plants, sometimes in the axils of leaves or on the tips of leaves. Hatching occurs in a few days and young larvae penetrate into the internode of the stem. It first excavates a fine gallery which is perceptibly horizontal, then ascends irregularly without going beyond the node situated just above. As many as 3 larvae have been found in the same internode. The plant, hindered in development, sometimes appears sinuous and folded. Larvae mature in about 3 weeks and leave the plants through very conspicuous, little round holes at the ground level. Pupation takes place in the soil 6-8 days later and adult emergence occurs in 18-21 days. Adult feeding takes place on wild grasses and hibernation occurs at the base of grass tufts. Mating and Oviposition occur the following spring. Only one generation a year has been recorded. C. t. tibialis appears as early as April in France. They begin feeding on leaves of saltbush, Russianthistle and beets, riddling them with holes which encroach on the parenchyma but do not go through it. Copulation occurs around the first of May and oviposition begins almost immediately. Eggs are laid on the ground. Larvae hatch and feed on roots of host plants. Apparently 2 or more generations occur each year in France. Adults of the last, and even the preceding generations, overwinter. Overwintered adults of C. concinna appear as early as the last of April and immediately attack leaves of Polygonum. Copulation and oviposition occur during the warm hours of the first fine days. Isolated eggs are deposited in the ground at the base of host plants. Incubation takes 15-30 days, after which young larvae hatch and excavate fine superficial galleries in the roots of Polygonum. Larvae mature in about 28 days and leave plants to pupate in the soil. New adults emerge in about 30 days and seek hibernation quarters. The life cycle of C. t. breviuscula is similar to that of C. concinna and C. t. tibialis with the exception that larvae feed on the roots of sugar beets. Descriptions; The species of Chaetocnema that attack grain crops, C. aridula and C. hortensis, are similar in appearance as are the species and subspecies that attack sugar beets, C. concinna, C. t. tibialis and C. t. breviuscula. Detailed illustrations of C. aridula and C. concinna can be found on pages 881 and 882. Adult descriptions follow. C. aridula and C. hortensis ADULTS - Length 2.5 mm.; moderately shining metallic greenish to bronze piceous; head wide; frons without longitudinal oval relief between points of insertion of antennae that is found in C. concinna. Punctation of head rather fine, more marked at inner margin of eyes. Supraantennal plates inconspicuous (see fig. II). Antennae 1l-segmented; first 5 more or less tinted with yellowish. Pronotum uniformly punctate; narrow flange on base and sides. Metasternum regularly punctate ‘poth on its disc and on its sides (see fig. II). Scutellum smooth; elytra dark, dullish bronze with irregular punctures, sometimes more or less lined up in form of striae. Legs yellowish or brownish, with exception of femora which are greenish black. Four hind tibiae show externally, at the level of their terminal third, a large tooth underlined by a fringe of hairs, which represents the extremity of the very strongly lengthened tarsal basket. Tarsi 4-segmented; third widened and grooved (notched). First segment of four front tarsi in males very conspicuously dilated and as long as other 3; posterior femora strongly swollen. - 881 - Adults of C. aridula and C. hortensis can be separated by the following: 1. Top of head and surface of pronotum more finely punctate than the frons and the face. Elytra punctate at random, except sometimes behind and on the sides. Segments of the base of the antennae spotted with brown above, at least the first. Front femora of a metallic greenish black. General form rather elongated. -------- C. aridula. 2. Top of head and surface of pronotum strongly and densely punctate with punctures as strong as those of the frons and of the face. Elytra showing twin punctures in pairs and forming rather conspicuous striae behind and on the sides. Segments of the base of the antennae of a uniform yellow, without a spot. Front femora oft ay browndsh | placky ———————— -C. hortensis. Figure II. Illustrations of Chaetocnema aridula (Gyll.) : A - Adult seen from above. B - Front tarsus of female; C - same in profile. D - Front tarsus of male; E - same in profile. F - Head seen from above. G - Underpart of metasternum showing punctation. C. t. tibialis and C. concinna ADULTS - Small, 1.5 mm. long, relatively wide and rather strongly arcuate above. General color rather dull metallic green with more or less coppery reflection on head and prothorax. Antennae black, except for first 5 segments which are testaceous. Legs colored as follows: All femora black; tibiae and tarsi testaceous. C. t. tibialis head shows, between the antennae, a longitudinal oval elevation laterally edged by a row of punctures (or dots) which is prolonged and curved in along the cheeks. (see fig. III). Pronotum rather arcuate, densely and distinctly punctate; behind its anterior angles is found a well-marked callus; its sides distinctly flanged, but its posterior margin is not. This is the essential character permitting separation of C. t. tibialis from C. concinna. C. concinna shows a pronotum that is finely flanged behind all along its base; elytra with well-marked punctate striae; interstriae dull, finely punctate and reticulate. Males of both C. t. tibialis and C. concinna show greatly dilated first tarsal segments which are 2 times wider than the following ones. - 882 - C. t. breviuscula ADULT - It differs from C. concinna in that there are no Oblique depressions on the pronotum and no punctures near the base of the elytra. It differs from C. t. tibialis by the considerably smaller number of punctures on the frons between the eyes. Interspaces between punctate striae on elytra of C. t. breviuscula have small punctures, without transverse rugae; base of antennae, tibae and tarsi testaceous, lightly reddish; length 1.5-2.2 mm.

WEATHER OF THE WEEK ENDING SEPTEMBER 18 This week's weather was featured by hurricane Carla and beneficial rains in the northern Great Plains early in the week, an unusual temperature change east of the Rockies about midweek, and hurricane Esther's threat to the Atlantic coast as the period ended. Hurricane Carla and a cold front moving southward from Canada were responsible for most of the week's rainfall which was very heavy in much of the midcontinent area and extreme Northeast. Carla moved from Texas to the Great Lakes on the 11th to 14th, leaving 10 to 16 inches of rain along the first 50 miles of her path into Texas and over 5 inches from Texas to Michigan. Carla was blamed for 43 deaths and hundreds of millions of dollars damage, and heavy rains caused widespread flooding along her path. The cold front rains during the first 3 days in the northern Great Plains totaled over 2 inches in much of the Dakotas and parts of eastern Montana. The rains provided much-needed moisture, especially in eastern Montana. After Carla's passage the cold front moved into the southern Great Plains and was responsible for 7 to 11 inches of rain in the lower Rio Grande Valley of Texas on the 13th and 14th and light to moderate rainfall in the eastern part of the country on the 14th and 15th. West of the Continental Divide showers, mostly light, occurred near the end of the period. With the passage of the cold front about midweek, temperatures dropped 20° to 30° and relative humidity about 20 percent, thus, abruptly ending the period of hot, humid weather that had persisted for 3 weeks in many areas east of the Rockies. Minima fell below freezing at many northern stations and to the lowest level on record for early September at some stations in the central portion of the country. Ardmore, South Dakota, reported 18°; Sibley and Oelwein, Iowa, 32°; and Norfolk, Connecticut, 25°. Frost occurred over all of Nebraska with temperatures as low as 22°, and in some sections of Kansas with a low of 30° at Atwood. Temperatures for the week averaged 6° to 12° below normal between the Mississippi River and the Rockies, and generally within 3° of normal elsewhere. At the end of the pericd the large and dangerous hurricane Esther was moving toward the Atlantic coast. On Tuesday morning, September 19, hurricane warnings were displayed from Cherry Point, North Carolina, to the Virginia Capes. (Summary supplied by U. S. Weather Bureau). - 885 - CEREAL AND FORAGE INSECTS GRASSHOPPERS - NEW MEXICO - Populations threatening or above on total of 790,000 acres of rangeland, mostly in eastern portion of State.

Preparation of this information by each county involved a great deal of work; and yet, this data must of necessity be considered an estimate only, as all final crop report information is not available at the time of preparation. Animal pests are included in the estimate, but are not complete as they represent only a few counties. This year most county reports were complete, giving estimated crop value, percentage loss caused by insects and cost treatment. Considerable reinterpre- tation of the data presented was necessary for a comprehensive final report. There are some 250 different kinds of commercial crops grown in the State on 131,000 farms. The diversity of crops, geographical differences encountered with- in the State, and local cultural practices all contribute to the recording of a wide variety of insect/mite pests. Damage and loss figures from minor pests are not usually reported and are not included in the statistics. The totals for assessable yield loss and control costs do not always equal the estimated overall total due to the overlapping of treatments for several insects and other associated factors. In some instances one set of figures was not available and has been omitted. For a more accurate representation of statewide percent loss, the highest-lowest value is given rather than an average. Forest insect estimates are included in cooperation with the U. S. Forest Service, Pacific Southwest Forest and Range Experiment Station. Structural and commercial pest control is also represented. This section includes termite control and common household pest costs, along with the rodent control. Due to "termite clearances" incident to sale or transfer of property as required in many escrow instructions and by loaning agencies, termites have remained the number one structural pest.ias a rather high percentage of infestations occurs. Estimated dollar costs for individual structural pests is practically impossible as treatment for a combination of pests is of general practice in the industry. Information on structural pest control is furnished by the Pest Control Operators of California, Inc. In cases where a damage-loss figure is assigned to a single species, it is so credited, whereas such assignments for broader groups comprising more than one species are reported compositely. Loss costs of 36 individual pests listed ran over a million dollars. The attached table presents the breakdown of assigned damage-loss dollar value. Ronald M.

Woodruff et al. A CHINCH BUG (Blissus leucopterus insularis) - Damage is figured for St. Augustine grass lawns and has not changed from the estimate used for 1958. Loss - $6,500,000 Insecticide costs - $17,000,000 FLORIDA RED SCALE (Chrysomphalus aonidum) and PURPLE SCALE (Lepidosaphes beckii) - These two species are combined because of difficulty in separating damage caused by each. This figure is based on a 2 percent loss in crop value due to these two scale insects. Florida red scale is the more important of the two. Loss -— $5,300,000 Insecticide costs - $4,500,000 CITRUS RUST MITE (Phyllocoptruta oleivora) on citrus - This estimate is made on a single crop (citrus) damage and based on a 1.5 percent loss. Loss - $4,000,000 Insecticide costs - $3,750,000 i} A SERPENTINE LEAF MINER - A pest of several important Florida crops, including potatoes, tomatoes, cucumbers, watermelons, okra, celery and beans. Loss - $3,000,000 Insecticide costs - $2,000,000 SPIDER MITES on citrus - This is a composite group of pests, all very closely related and belonging to the family Tetranychidae. Nearly all of the one percent damage to citrus is caused by the following: CITRUS RED MITE (Panonychus citri), TEXAS CITRUS MITE (Eutetranychus banksi) and SIX-SPOTTED MITE (Eotetranychus sexmaculatus) . Loss - $2,670,000 Insecticide costs -— $1,500,000 CORN EARWORM (Heliothis zea) - The loss attributable to this insect is based on a damage estimate of 10 percent of the crop value. This high percentage is probably near the correct estimate since untreated corn ears were 40 to 100 percent infested. Loss - $1,312,500 Insecticide costs - $192,000 SOUTHERN ARMYWORM (Prodenia eridania) - Damaged tomatoes, potatoes, tobacco and various other crops. Some of the damage attributed to this species may apply to fall armyworm, however. Loss - $750,000 WIREWORMS - There are several species of Elateridae involved in the State, but SOUTHERN POTATO WIREWORM (Conoderus falli) seems to be the most abundant. About 50 percent of the damage done to potatoes can be attributed to wireworms. Loss - $500,000 FALL ARMYWORM (Laphygma frugiperda) - There are other species of armyworms which probably caused as much damage as this species. Some of the southern armyworm damage can also probably be attributed to this species. Loss - $350,000 - 905 - 10. CABBAGE LOOPER (Trichoplusia ni) - This species was the major pest of shade- grown tobacco in 1959, replacing TOBACCO BUDWORM (Heliothis virescens). Cabbage and tobacco were both damaged in 1960.

FR OK KK 26 2K 2K 2K KK Reports in this issue are for week ending September 22 unless otherwise indicated. - 908 - WEATHER OF THE WEEK ENDING SEPTEMBER 25 Cold air covering the Far West at the beginning of the period pushed eastward to a line joining Cleveland, Ohio, and Dallas, Texas, by the end of the period. Below- normal temperatures prevailed all week in most of this area, with freezing wide- spread in central and northern interior areas. Temperatures for the week averaged as much as 12° below normal in the central and northern Rockies. Elsewhere in the Nation, temperatures rose from below-normal levels at the begin- ning of the period to midsummer levels by the end. Weekly averages were 3° to 6° above normal in the Ohio Valley, eastern Great Lakes region and the Northeast. Some northeastern sections reported near-record heat for so late in September. Little or no precipitation fell in the extreme western and southern portions of the country, but most other areas received generous amounts which were particularly beneficial in the northern Great Plains and parts of the Far West. Moderate to heavy amounts were general in North Dakota where several stations measured more than 2 inches. Weekly totals exceeded an inch in most of South Dakota. General moderate to heavy amounts in Montana furnished adequate topsoil moisture, except north central areas, and even replenished subsoil moisture locally. This benefi- cial precipitation extended over much of Idaho, Utah, Wyoming and northeastern Nevada. Snow fell in the central and northern Rockies, and the higher mountains in Montana are now snowcapped. Heavy snow fell in the mountains of northern Colorado; 6 to 12 inches or more were record amounts for September in some areas. Rainfall along the Atlantic coast virtually all fell during the passage of hurri- cane Esther early in the week. Totals generally ranged from 1 to 2 inches in the lower Appalachians and along the middle and north Atlantic coast, except in south- eastern New England and Long Island, where amounts ranged up to more than 4 inches. Esther caused damage in coastal areas from New Jersey to southern New England that probably totaled a few million dollars. On the 22d, a small tornado and hail north of Grand Rapids, Michigan, damaged crops and orchards, chiefly fruit; losses were estimated at $2 to $3 million. (Summary supplied by U. S. Weather Bureau). = G08) = CEREAL AND FORAGE INSECTS GRASSHOPPERS - INDIANA - Melanoplus differentialis and M. femurrubrum counts in Ripley, Decatur and Shelby Counties ranged 2-12 adults per square yard; some damage to beans and leaf feeding on corn readily observed.

Alfalfa or alfalfa-grass mixtures principal grasshopper habitat, but high populations also observed in most other legumes and in grass plantings in some instances. Economic numbers observed in or associated with Conservation Reserve land in many instan- ces, causing considerable trouble in some areas. In fields with threatening to severe populations, approximately 30 percent in Conservation Reserve land and remaining 70 percent in crop or pastureland, indicating most infested acreage in croplands. Heavy damage occurred to hay crops in fields with high populations; less damage to soybeans, corn and some small grains in adjacent areas. Some controls applied to soil bank fields, roadsides and croplands; treated acreage generally limited. M. femurrubrum dominant species in all districts, followed by M. bivittatus and M. bilituratus in northwest. Increases in Camnula pellucida and M.

Several species of FLIES were reared from an African snail (Achatina fulica) which had been killed by a commercial snail bait. During May and June 1961, bait was set out at 8 locations in Honolulu and windward Oahu. A sample of the dead snails was taken from each collection 5 to 6 days after baiting and kept in the insectary for 6 weeks. A total of 158 snails yielded 109 specimens of Megaselia setaria, 245 Fannia pusio, 59 Helicobia morionella and 192 Sarcophaga misera. The absence of calliphorids, especially Chrysomya megacephala, was noteworthy. When crushed A. fulica was used as a bait in Honolulu, 49 percent of the flies trapped were calliphorids and the overwhelming majority of these were C. megacephala. (Wilton).

Above normal temperatures are predicted in the area from the Northern Rocky Mountain States westward to the Pacific coast, and also in California. In unspecified areas, near normal averages are in prospect. Precipitation is expec-— ted to exceed normal in the Atlantic Coast States, the Gulf States and Southern Plateau Region. Subnormal amounts are indicated for the area from the Upper and Middle Mississippi Valley westward to the Pacific coast, with near normal amounts elsewhere. Weather forecast given here is based on the official 30-day "Resume and Outlook", published twice a month by the Weather Bureau.

WEATHER OF THE WEEK ENDING OCTOBER 2 Abnormally cool weather prevailed over all except the extreme eastern and southern portions of the country this week as three successive cold air masses moved across the Nation from the Northwest. Average temperatures for the week ranged from 12° below normal in the northern Great Plains to 6° above normal in northeastern Maine. Coldest weather occurred in most areas late in the week when freezing and frost were widespread in all northern areas. Low temperatures ranged from near zero degrees to 15 degrees in the central Rocky Mountains, and freezing was reported in the Texas and Oklahoma Panhandles. The first general freeze of the season occurred in Iowa on the 28th when Carroll reported a low of 24°. This freeze on the 28th ended the growing season for most fall-maturing crops in many extreme north central interior areas. Freezing occurred in much of the upper Ohio Valley and Northeast on September 29 and 30. Ohio reported its first frost on the 29th and scattered frost occurred in West Virginia and western and northern Maryland on the same date. Although cooler weather moved into the Northeast on September 29 and 30, owing to abnormally high temperatures the early part of the week, temperatures averaged above normal. This was the sixth consecu- tive warmer than normal week in New England and some adjacent areas, where the past September was among the warmest on record. Precipitation was extremely light in the western half of the Nation and spotty east of the Great Plains. Eastern New England received from about 1.50 to 3.00 inches of rain when former hurricane Esther returned on September 25 and 26. Frontal rains of more than an inch were measured in the Great Lakes region and the Ohio and upper Mississippi Valleys. Arkansas, eastern portions of Kansas, Oklahoma and Texas, and northern Louisiana also measured over an inch of rain. Little or no precipitation fell in most of the Southeast and from the southern Appalachian region northward through New York State. Snow fell in the central Rocky Mountains and several north central areas. One to 7 inches were reported in the vicinity of the Black Hills of South Dakota and a trace in most of the remainder of the State. Traces also fell in an area from the southwestern corner of Minnesota to Minneapolis, with accumulations of 1 to 4 inches in the New Ulm-Mankato area. (Summary supplied by U. S. Weather Bureau). = G25 = CEREAL AND FORAGE INSECTS GRASSHOPPERS - WISCONSIN - Grasshoppers continued noticeable despite low temper- atures; populations reduced about half in some fields.

FO OR OR RK RK aK OK Reports in this issue are for week ending October 6 unless otherwise indicated. - 944 - WEATHER OF THE WEEK ENDING OCTOBER 9 Typical autumn weather with mild, sunny days and cool nights prevailed in most of the Nation on about 5 days this week. A cold front accompanied by light to heavy precipitation, and followed by much-below-normal temperatures, moved across the Atlantic and Gulf Coastal States at the beginning of the week. Heaviest rainfall occurred in the Appalachians where totals exceeded 2 inches at many stations. Lightest amounts fell in the southeastern coastal areas where amounts were negligible in southern Georgia and most of Florida. Almost all areas of the latter State now need rain badly. The first part of the week was cooler than normal in the South and East and the latter part unseasonably mild. In most of the South, temperatures for the week averaged from about 6° to 9° below normal, but in New England weekly averages generally ranged from about 2° to 6° above normal. This was the seventh consecutive abnormally mild week in the latter area. In the north-central interior portion of the country, average temperatures for the week were normal or slightly above, and precipitation was negligible. Temper- atures, even though rising, were much below normal at the beginning of the period, with minima in the 20's in the extreme north and frost as far south as western Kansas. By the 6th, maxima had risen into the 80's and 90's as far north as South Dakota and into the 70's and 80's in Minnesota. A cold front moved across the northern Great Plains on the 6th and 7th, however, and by the 8th maxima had fallen into the 40's. In the Far West, fair and mild weather was interrupted the latter part of the week by a cold front which brought much colder weather and scattered precipita- tion. Precipitation was heaviest in the central Rockies where heavy snows fell. Snowfall ranged up to 2 feet in Wyoming, and a heavy accumulation occurred in the mountains of northern Utah. Light snow fell at altitudes above 5,000 feet in Arizona. On Thursday and Friday, high winds in eastern Washington caused some crop damage and dust reduced visibility. Winds up to 50 m.p.h. caused some damage along the central California coast and aggravated a 2,000-acre fire in the Sequoia National Forest. (Summary supplied by U. S. Weather Bureau). = 945 - CEREAL AND FORAGE INSECTS CORN EARWORM (Heliothis zea) - UTAH - Adults scarce. Damage to corn generally light in northern and central areas; occasionally heavier in southern part of State. (Knowlton). SOUTH DAKOTA - Populations low in south central and south- eastern areas; only 2 larvae found in 800 corn ears inspected. (Hanten). WISCONSIN - Larvae feeding heavily on sweet corn in Dane County. (Wis. Ins. Sur., Oct. 2). OKLAHOMA - Light populations (1 per sweep) noted on alfalfa in Payne County. (Okla. Coop. Sur.). TEXAS - Light infestations of one larva per 10 heads noted in Hale County. (Newton). LOUISIANA - Marked adult activity on Dallasgrass infected with ergot. (Newsom, Chapin). ALABAMA - Light on corn in Lee County. (Guyton). VIRGINIA - Averaged 1.5 third instars per 10 soybean plants at locality near Chesterfield, Chesterfield County. Average of 2 percent of pods per plant damaged. (Matheny, Sept. 20). DELAWARE - Larvae in alfalfa statewide and in soybeans in Kent County. (Burbutis, Mason). SUGARCANE BORER (Diatraea saccharalis) - TEXAS - Caused local, heavy damage to grain sorghum in Brazos and Burleson Counties. (Newton). LOUISIANA - Causing light damage in few fields of late-planted rice in Port Barre area, St. Landry Parish. (Newsom, Chapin). RICE STALK BORER (Chilo plejadellus) - LOUISIANA - Causing light damage in few fields of late-planted rice in Port Barre area, St. Landry Parish. (Newson, Chapin). CORN LEAF APHID (Rhopalosiphum maidis) - ARIZONA - Infestations continue to increase in central and southeast area sorghum; now heavy in many fields. (Ariz. Coop. Sur.). OKLAHOMA - Some local, very light populations noted on wheat checked in northwest area. (Okla. Coop. Sur.). SOUTH DAKOTA - Populations considerably reduced due to frost and dry weather in southeast area; very little green corn present. (Hanten). RUSTY PLUM APHID (Hysteroneura setariae) - ARIZONA - Continues to increase on sorghum in central and southeast areas; now heavy in many fields. (Ariz. Coop. Sun) YELLOW SUGARCANE APHID (Sipha flava) - OKLAHOMA - Generally light on volunteer plants in field of wheat checked in Harper County. (Okla. Coop. Sur.). AN APHID (Aphis armoraciae) - CALIFORNIA - Heavy populations occurring on corn plantings in Ceres area, Stanislaus County. (Cal. Coop.Rpt.). A ROOT APHID (Rhopalosiphum rufiabdominalis) - WYOMING - Infesting small grains in greenhouses at University of Wyoming, Albany County. (Fullerton). NORTHERN CORN ROOTWORM (Diabrotica longicornis) - SOUTH DAKOTA - Adult populations reduced to scattered individuals in much of southeast area. However, adults numerous on corn ears in Minnehaha County. (Mast). RICE WEEVIL (Sito hilus oryzae) - LOUISIANA - Heavy on corn in field in St.Landry Parish. (Newsom, Chapin). GRASSHOPPERS - OKLAHOMA - Several species caused some localized marginal damage in fields of wheat checked in northwest area. (Okla. Coop. Sur.). WISCONSIN - Melanoplus femurrubrum remains plentiful in southeastern area, especially along roadsides. (Wis. Ins. Sur.). SORGHUM MIDGE (Contarinia sorghicola) - ARIZONA - First collection in State made in Kansas Settlement area of Cochise County, October 3. Initial surveys show most unseasonably late-planted grain sorghum in county infested, with 25-40 percent loss of grain common. Grain planted normally and now in harvesting stage not noticeably affected. Further surveys necessary to determine extent of infesta- tion. (Ariz. Coop. Sur.). TEXAS - Caused local heavy damage to grain sorghum in some sections of panhandle area. (Newton). 9460 — HESSIAN FLY (Phytophaga destructor) - NEBRASKA - Main adult emergence from samples collected occurred in eastern and central areas,September 18-25. (Bergman) . TWO-SPOTTED. SPIDER MITE (Tetranychus telarius) - CALIFORNIA - Medium on milo plantings in Knights Landing, Sutter County; light in Sacramento, Sacramento County. (Cal. Coop. Rpt.). SPOTTED ALFALFA APHID (Therioaphis maculata) - IDAHO - Some controls still required on late-emerging, fall-planted alfalfa in southwest. Many newly planted, untreated fields being abandoned as a complete or near-complete loss. (Waters). OREGON - Remains low in alfalfa in Malheur County from Adrian to Ontario. Aphids generally distributed throughout Umatilla County; no controls have been necessary this season. Newly seeded alfalfa in Stanfield area found infested October 4, but it is believed weather conditions unfavorable for development will reduce aphid populations before serious damage occurs. (Capizzi). CALIFORNIA - Medium on alfalfa in Siskiyou, Siskiyou County; heavy in Jacumba, San Diego County. (Cal. Coop. Rpt.).

Citrus Insect Situation in Florida - End of September - CITRUS RUST MITE (Phyllocoptruta oleivora) infested 71 percent of groves (norm 59 percent); 46 percent economic (norm 38 percent). Statewide population above average and will increase during October; high percent of groves in all districts will harbor destructive infestations. Highest districts with threatening conditions are west coast, Bartow, Gainesville, Brooksville and ridge. CITRUS RED MITE (Panonychus citri) infested 30 percent of groves (norm 42 percent); 7 percent = 949 7— economic (norm 21 percent). Infestations fewer and lighter than any year since 1950. Although increase will occur in October, only a few scattered groves will develop important infestations. TEXAS CITRUS MITE (Eutetranychus banksi) infested 21 percent of groves; 4 percent economic. Increasing trend will prevail, but no district will develop high populations during October. FLORIDA RED SCALE (Chrysomphalus aonidum) infested 58 percent of groves (norm 58 percent); 4 per- cent economic (norm 10 percent). Populations currently low in most districts. Current upward trend will cause spotty infestations to appear. Highest dis- tricts are upper east coast, with threatening conditions, and Indian River. PURPLE SCALE (Lepidosaphes beckii) infested 58 percent of groves; 2 percent economic. Slight increase from current low population level will occur, but only light infestations are expected. (Simanton, Thompson, Johnson (Citrus Exp. Sta., Lake Alfred)). General Forecast, Citrus Insects in Florida - October through December - CITRUS RUST MITE population will increase rapidly in October and continue above average level through November; decline to average level expected in December, with buildup more noticeable on leaves than on fruit. CITRUS RED MITE infestations will become more numerous in late October and November, but population generally will remain below average. A gradual increase of TEXAS CITRUS MITE will occur through November and population will approach the moderately high level recorded previous fall; expected to be a problem in more groves than in prior years. FLORIDA RED SCALE populations will be below average; infestations expected to be light and spotty. Although PURPLE SCALE infestations will be common, very few will reach destructive level. CHAFF SCALE (Parlatoria pergandii) will occur in about 50 percent of groves and increase gradually; occasional groves may develop infestations capable of downgrading crop as fresh fruit. (Simanton).

Current Status of Screw-worm (Callitroga hominivorax) Infestation in the Southeastern United States The first infestation found in the eradication area, other than the case in Holmes County, FLORIDA, during the calendar year 1961, was discovered in a native animal in western MISSISSIPPI near Vicksburg on August 15. Numerous cases were found in this area of Warren County, and shortly after infestations were reported in De Soto County, Mississippi, which is in the extreme northwestern corner of the State. No infestations had been reported in this area since the initiation of the eradication in the Southeast. After being disclosed in northwestern Mississippi, infestations were soon found in herds in several counties in western TENNESSEE near Memphis. Numbers increased rapidly and numerous infes- tations were reported in many herds and some reinfestations occurred. In slightly over 2 weeks, an infestation was reported by a veterinary practitioner in Franklin County on the Alabama border in middle Tennessee. Almost immediately after this discovery, ALABAMA reported the pest in the northern section of Madison County near Huntsville. From this initial foci of infestation in Alabama, screw-worm spread in the immediate area to 5 counties in Alabama and Floyd County, GEORGIA.

MISCELLANEOUS INSECTS EUROPEAN CHAFER (Amphimallon majalis) - MASSACHUSETTS - The following statement was issued by P. C. Kusmiski, Assistant Director, Division of Plant Pest Control, Department of Agriculture, Commonwealth of Massachusetts, to Plant Pest Regula- tory Officials of the States on October 4, 1961. ''Reference is made to the mailed notice dated August 30, 1961, relative to the finding of European chafer in Massachusetts. Subsequent information on this matter has revealed that previously collected adults of this insect from a known infested area outside of Massachusetts were inadvertently included with other insects collected in Massachusetts from a light trap used by a student for his insect collection project. As these were the adults submitted for official identification and the establishment of a first find, it is now in order to void the first find record as stated in the above referred announcement dated August 30, 1961. Cooperative visual and soil surveys, as well as trapping for the possible presence of this insect in Massachusetts are planned for the next spring and summer.''

Above normal temperatures are predicted for the Far West as well as the Northern and Central Plains. In the remaining area, near normal averages are indicated. Precipitation is expected to be subnormal over most of the country except for near normal amounts along the Gulf Coast, and for amounts in excess of normal over the Northeast. Weather forecast given here is based on the official 30-day "Resume and Outlook", published twice a month by the Weather Bureau.

WEATHER OF THE WEEK ENDING OCTOBER 16 Dry, Sunny weather and unseasonably mild temperatures prevailed in most areas east of Mississippi River until a cold front passage on Friday and Saturday brought moderate to heavy precipitation to the Northeast and light to moderate amounts along the Atlantic coast. Following the passage of the front, abnormally cold, windy weather persisted through the weekend. New England reported its first general snowfall of the season and the earliest in 27 years. Some snow also fell at higher elevations in New York and New Jersey and in the mountains of eastern Tennessee. Amounts in New England, although generally only a trace, ranged up to near 1/2 inch in northwestern Connecticut, up to 2 inches in the mountains of Massachusetts and New Hampshire, and up to 6 inches in northern Maine. Little or no precipitation fell in most southern areas, and soil moisture is short in much of the Southeast. The central and southern portion of the Florida Peninsula was an exception, as a soil moisture shortage there was relieved by showers all week along the southeast coast and after midweek in other central and southern portions of the Peninsula. The weather was also generally abnormally mild from the Mississippi River to the Rockies until Thursday and Friday when a change to much colder occurred. Moderate to heavy rains fell in a belt extending from south-central Texas to the upper Mississippi Valley. Amounts ranged up to more than 3 inches at many stations in the eastern portions of the Great Plains and 4.20 inches in 24 hours on the 10th and llth set a new record for Huron, South Dakota. Damaging winds and lightning accompanied the rains in Wisconsin and hail was reported in several counties of Iowa. In the Far West, precipitation fell in the Rocky Mountain area at the beginning of the week and in the Pacific Northwest during the first half. Heavy drifting snow was reported in Wyoming and snow fell in some mountain areas of Colorado. Most of Utah received light to moderate precipitation early in the week, but Nevada received only light amounts in the northeast. Only light amounts fell in eastern Montana, where topsoil moisture is short in north- central and northeastern areas. Temperatures rose to unusually high levels along the southern California coast over the weekend when maxima rose to well over 100°. Temperatures for the week averaged well above normal in New England for the eighth consecutive week. From the Great Lakes eastward weekly averages ranged up to 6° above normal, and also along the southern California coast. Elsewhere in the Nation, temperatures for the week averaged within 3° of normal. However, this was the sixth consecutive cold week in Wyoming and some other central Rocky Mountain areas.

Many others caused lesser amounts of damage and loss to forest stands and plantations. As a group, BARK BEETLES were the most important pests and several large-scale outbreaks occurred in the Western and Southern States. DEFOLIATING INSECTS were also important in many sections of the country, particularly in the Central States, the South, Southeast and along the Atlantic coast. SAWFLIES were abundant in many pine plantations in the eastern half of the Nation and several outbreaks occurred in forest stands in the East, South and West. Miscellaneous pests, including WEEVILS, APHIDS, SCALE INSECTS, SHOOT and TIP MOTHS, NEEDLE MINERS, SPITTLEBUGS and many others, were troublesome in local areas countrywide. Other insect infestations and conditions of regional significance were as follows: EUROPEAN PINE SHOOT MOTH was discovered in several additional communities in WASHINGTON and in Portland, OREGON; the program of importing insect predators to control the BALSAM WOOLLY APHID in the Northeast, the Pacific Northwest and NORTH CAROLINA was continued; the LARCH CASEBEARER continued its spread in northern IDAHO and eastern WASHINGTON; and a RED-PINE SCALE (Matsucoccus resinosae) was discovered for the first time in NEW JERSEY. Forest Insect Conditions in General: MOUNTAIN PINE BEETLE (Dendroctonus monticolae) was the most important bark beetle in 1960 and epidemics of varying magnitude occurred in several of the Western States. Stands of lodgepole pine in UTAH and IDAHO were particularly hard hit. Old-growth stands of western white pine in north Idaho were severely attacked and centers of infestation developed or continued in second-growth stands of ponderosa pine in parts of OREGON, CALIFORNIA, NEVADA and Idaho. Suppression of infestations was under-— taken in most outbreak areas. The largest project, on the Ashley National Forest, Utah, involved felling and treating of 166,808 infested trees. The Ashley project and others in the Western States resulted in treating 185,567 trees at a cost of $849,876. In addition to the above named states, several damaging infestations were reported in areas of WASHINGTON, WYOMING and MONTANA. ENGELMANN SPRUCE BEETLE (D. engelmanni) also was especially destructive during 1960. Outbreaks of most Significance were in the high elevation stands of where green trees had been blown down by strong winds. The most serious of the infestations occurred on the Uinta, Ashley and Wasatch National Forests, Utah. Others of nearly equal importance were on the national forests in southern Colorado and northern New Mexico. Infestations were suppressed in most outbreak areas by treating infested trees, cull logs and stumps. In some areas, green trees were felled to trap attacking beetles. To the extent feasible, trap trees were later logged and, wherever possible, infested trees also were salvaged. Suppression in all outbreak areas involved the treatment of 56,111 infested trees, stumps and windfalls at a total cost of $237,156. The number of centers of Engelmann spruce beetle infestations in OREGON and WASHINGTON increased consider- ably, but the total infested acreage declined somewhat from prior years. Most of the infestations were in stands scattered along stream bottoms. * Information contained in the Forest Insect Summary - 1960, was supplied by entomologists at the Forest and Range Experiment Stations, U. S. Forest Service. Copies of the "Forest Insect Conditions in the United States - 1960", as issued by the Forest Service, may be secured by request from the Division of Forest Insect Research, Forest Service, USDA, Washington 25, D. C. = 2/5 = BLACK TURPENTINE BEETLE (D. terebrans) was the primary insect in the Southern and Southeastern States. There were no major outbreaks, but tree-killing in moderate amounts was widespread and aggregate losses thus were severe. Exceptionally large acreages of pine stands were affected in LOUISIANA and MISSISSIPPI. Smaller acreages were infested in east TEXAS, ALABAMA, ARKANSAS, NORTH CAROLINA and SOUTH CAROLINA. Suppression of infestations was undertaken by treating infested trees or by salvage. In all, 548,810 trees and stumps were treated at a cost of $146,425. No estimate is available of how many thousand trees were salvaged. SOUTHERN PINE BEETLE (D. frontalis) continued to pose a serious threat to the extensive stands of southern pines in east TEXAS, ALABAMA and other Southern and Southeastern States. Group-killing of trees was widespread in east Texas during the early summer. The threat of heavier loss and spread of infestation was averted, temporarily at least, by prompt suppression in all accessible areas. A total of 134,299 infested trees in outbreak areas were treated at a cost of $119,758. Thousands of additional infested trees were salvaged. Populations were generally low throughout the Southeast, except in the Pickens District of the Sumter National Forest, SOUTH CAROLINA; in coastal pond pine in Dare and Tyrrell Counties, NORTH CAROLINA; and in Accomack and Northampton Counties, VIRGINIA. WESTERN PINE BEETLE (D. brevicomis) was troublesome within its range in the Western States. In CALIFORNIA, outbreak numbers occurred in a number of ponderosa pine stands adjacent to large burns and in areas of deficient precipi- tation in the Sierra Nevada Mountains below 5,000 feet elevation. Some local infestations were reported in northern IDAHO and in areas of MONTANA. Epidemic conditions lessened in most areas of WASHINGTON, but the infestation continued upward in most areas of OREGON; the increase being most noticeable on the Fremont, Malheur and Ochoco National Forests. BLACK HILLS BEETLE (D. ponderosae) was also troublesome within its range in the Western States. Populations in ponderosa pine stands in southern UTAH have shown a definite downward trend for the past several years, but increased in ponderosa pine along the Front Range of the Rocky Mountains. The greatest increase was reported on the Pike and San Isabel National Forests in COLORADO and on the Bighorn National Forest in WYOMING. The number of trees killed increased seven- fold as compared with 1959 in some areas of the latter two States. Infestation decreased in the Black Hills of SOUTH DAKOTA and were locally moderate on parts of the Carson National Forest in northern NEW MEXICO. The widespread epidemic of DOUGLAS-FIR BEETLE (D. pseudotsugae) that caused heavy losses in stands of Douglas-fir in areas of southern OREGON during the past 3 years subsided,except for a small outbreak center near the Oregon Caves National Monument. In WASHINGTON, infestations on the Colville Indian Reservation and Okanogan National Forest continued upward. No significant outbreaks were reported in CALIFORNIA. The beetle was abundant throughout south IDAHO, western WYOMING and UTAH, with Douglas-fir stands on the Sawtooth National Forest, Idaho, and on the Dixie National Forest, Utah, being particularly hard hit. Infesta- tions increased sharply throughout Douglas-fir stands in ARIZONA and NEW MEXICO, but were less severe than for the past few years in COLORADO and WYOMING. JEFFREY PINE BEETLE (D. jeffreyi) caused relatively little damage in CALIFORNIA, but ALASKA SPRUCE BEETLE (D. borealis) continued to cause epidemic losses of white spruce and Lutz spruce on the Kenai National Moose Range in southeast ALASKA and on several drainages of the adjacent Chugach National Forest. PINE ENGRAVERS (Ips spp.) were associated to varying degrees with most of the western pine beetle outbreaks in northern and central CALIFORNIA,and in several areas were aggressive in their own right. They were not a serious problem in the Intermountain and northern Rocky Mountain States, and they did not approach outbreak proportions in LOUISIANA, ARKANSAS and MISSISSIPPI despite late winter ice damage and severe summer drought conditions in parts of these latter States. = 270 = Ips spp. were often associated with southern pine beetle activity in east TEXAS and ALABAMA, Hurricanes in 1959 and 1960 were particularly destructive to stands of southern pines in Beaufort and Colleton Counties, SOUTH CAROLINA, and near Ft. Myers, FLORIDA. Ips spp. attacked the uprooted and broken trees, and beetles emerging from these trees attacked and killed many standing trees in South Carolina. This situation did not occur in Florida, however. In OREGON and WASHINGTON, the number of outbreaks of Ips oregoni increased, but the total infested acreage declined substantially from prior years. The Malheur and Wallowa-Whitman National Forests in Oregon suffered the bulk of the loss. I. oregoni was also reported killing tops of some mature ponderosa pines, as well as patches of pine reproduction on the Custer National Forest of MONTANA, scattered ponderosa pine in the northern Black Hills of SOUTH DAKOTA and top sections of pines in NEW MEXICO. Some mature ponderosa pines were killed by I. emarginatus on the Kaniksu National Forest of IDAHO and I. lecontei occurred in outbreak numbers in stands of second-growth ponderosa pine at several loca- tions on the Prescott National Forest of ARIZONA. Also in Arizona, an outbreak of CALIFORNIA FIVE-SPINED IPS (1. confusus) developed in pinyon pine adjacent to Walnut Canyon National Monument. I. avulsus weakened pines in ALABAMA enough to bring on attacks of southern pine beetle and later assumed a secondary role. A CEDAR BARK BEETLE (Phloeosinus Squamosus) was responsible for the death of large numbers of Alaska-cedar and western redcedar on Kuiu and Kupreanof Islands in the central part of the ALASKA Panhandle. FIR ENGRAVER (Scolytus ventralis) damage in OREGON and WASHINGTON was relatively unimportant during 1960, but the pest was much more abundant than usual and caused increased losses to white and red fir generally in CALIFORNIA. The killing of firs by this engraver was widespread in ARIZONA and NEW MEXICO, with the out- break covering approximately 25,000 acres on white fir on the Lincoln National Forest and the Mescalero Indian Reservation of New Mexico. Heavy broods of fir engraver were found in pole-sized grand fir near St. Maries, IDAHO. A small out- break of WESTERN BALSAM BARK BEETLE (Dryocoetes confusus) was reported in sub- alpine fir trees near Mt. Washburn, Yellowstone National Park, WYOMING, and large numbers of subalpine firs in southern COLORADO and northern NEW MEXICO were attacked and killed by this bark beetle. CALIFORNIA FLATHEADED BORER (Melanophila californica) continued to be an impor- tant factor contributing to the death of pines in various parts of CALIFORNIA. Some of the heaviest damage was in Jeffrey pine stands in the southern part of the State. WHITE-PINE WEEVIL (Pissodes strobi) damage was recorded throughout pine and Spruce stands in the Lake States. From 30 to 50 percent of the trees in many white pine and jack pine stands were infested and damage to red pines was also quite common. Treatments were applied in MICHIGAN and WISCONSIN. The pest was more destructive than usual in MASSACHUSETTS and damage was severe in NEW YORK. Generally, high populations prevailed over the Northeast. In CALIFORNIA, LODGE- POLE TERMINAL WEEVIL (P. terminalis) continued to cause damage to lodgepole pines. PALES WEEVIL (Hylobius pales) and Pissodes sp., probably approximatus, continued to be a problem in OHIO Christmas tree plantations where pine is cut and replanted within a year. Weevil damage occurred in most plantations in the eastern part of the State. Loss of year-old plantings in some instances reached 100 percent where replanting followed cutting soon after harvesting. An insect-canker complex on white pine was reported from Lake County, Ohio, during the early Spring. Heavy feeding by a pine weevil, tentatively identified as P. approxi- matus, was found consistently near the cankered areas. PINE CHAFER (Anomala oblivia) caused injury to about 2,500 acres of 2- and 3-year- old loblolly pines near Bolton, NORTH CAROLINA. The damage consisted of defolia- tion of current season's needles. = SHY = WHITE-PINE CONE BEETLE (Conophthorus coniperda) was quite abundant throughout New England where its toll on the seed crop was very high. In CALIFORNIA, the ponderosa pine seed crop was heavy and insect damage, mostly from PONDEROSA- PINE CONE BEETLE (GC ponderosae), was light. Damage to sugar pine cones was variable and the cone crop spotty, but in some localities SUGAR-PINE CONE BEETLE (C. lambertianae) killed practically all the cones. The SPRUCE BUDWORM (Choristoneura fumiferana) epidemics, a plague in the mixed conifer forests across the Nation, continued unabated in most areas. Infesta- tions in MINNESOTA increased in intensity and spread southward. Those in MONTANA, on a gross acreage of some 3,500,000 acres, were little changed from prior years even though a reduction in severity of defoliation and in moth popu- lations occurred in some places. In COLORADO and NEW MEXICO, outbreaks were the most extensive on record. Infestations in OREGON declined. The only known spruce budworm infestation in CALIFORNIA, which has been active but relatively innocuous for many years in white fir stands of the Warner Mountains, increased both in area and intensity in 1960. Populations were generally lower in southern IDAHO, except on the Challis and Targhee National Forests. Medium to heavy spruce budworm populations existed on balsam fir in the Ashland area of MAINE. Locations and acreages treated during 1960 in the various states were as follows: Maine, 217,000; Minnesota, 24,332; Montana, 117,845; Colorado, 500. Costs of aerial treatments on the 359,677 acres averaged 1.08 dollars per acre. Of the several new or rarely collected forest insects in CALIFORNIA, one of the more important ones found in 1960 was LARGE ASPEN TORTRIX (C EORTIAGtEMD) - The first recorded outbreak of this pest in California was discovered in aspen stands in Modoc County. The species had been found only twice before in the State. JACK-PINE BUDWORM (C. pinus) populations increased greatly in jack pine stands in several areas of MINNESOTA and MICHIGAN and heavy defoliation was noted on extensive acreages in WISCONSIN. Defoliation was severe on 15,000 acres in Minnesota and 7,400 acres in Michigan. BLACK-HEADED BUDWORM (Acleris variana) populations declined sharply in the hemlock-spruce stands of southeast ALASKA late in the larval feeding period of 1960, and the light infestation that was present on the Yakima Indian Reservation of WASHINGTON subsided. A small outbreak of light intensity developed in the fir-hemlock stands on the Mt. Hood National Forest, OREGON, but caused little or no damage. EUROPEAN PINE SHOOT MOTH (Rhyacionia buoliana) , which was first discovered in western WASHINGTON in 1959, was found during 1960 at 2 localities in Spokane and many in Seattle and vicinity. One infestation was also found at Portland,OREGON, which was the first record in that State. Mugho and Scotch pines were most preva- lently attacked of the 15 species and varieties found to be infested in the 2 States. European pine shoot moth populations remained essentially unchanged from prior years in pine plantations in MICHIGAN and WISCONSIN. The southern half of Lower Michigan contained moderate to heavy populations and the northern half was lightly infested. Populations were higher than in 1959 in Manitowoc County, Wisconsin. In the Northeast, the pest was again a serious depredator of red and Scotch pines. It was especially severe in parts of PENNSYLVANIA and the northern panhandle of WEST VIRGINIA. The shoot moth is becoming a more serious pest in coastal MAINE from Freeport to Newcastle and on Bailey Island. NANTUCKET PINE TIP MOTH (R. frustrana) killed tips and retarted growth in young loblolly and short leaf pine plantations throughout the South. In some Southern States, it attracted more attention and comment than any other forest insect. The pest was also common throughout the growing season in the Southeast. Damage to Scotch pine was heavy in New Castle County, DELAWARE, and seedlings in a soil-bank planting in MARYLAND were 90 percent infested. Damage to new shoots of young red and jack pines by R. adana was found recently in MICHIGAN. This insect could become a serious nursery pest. Similar damage to that reported in Michigan was found in WISCONSIN, but the insect causing the damage was not = ie) = positively identified. A PINE TIP MOTH (Rhyacionia sp.) caused heavy damage to understory pine stands on Custer National Forest, MONTANA and SOUTH DAKOTA. Two small centers remained of an extensive outbreak of a LARCH BUD MOTH (Zeiraphera griseana) which occurred in stands of western larch in the Cascade Mountains of WASHINGTON in 1958. The outbreak caused no material damage to host trees. LARCH CASEBEARER (Coleophora laricella) spread over an area of more than 8,000 square miles, including practically all of northern IDAHO and parts of eastern WASHINGTON since its discovery at St. Maries, Idaho, in 1957. In 1960, defoliation was severe enough to be visible over an area of 532 square miles in the vicinity of St. Maries and on the adjacent St. Joe National Forest. Approximately 2,500 adults of the BRACONID PARASITE (Agathis pumila) were released near St. Maries in an effort to promote biological control of the casebearer. DOUGLAS-FIR TUSSOCK MOTH (Hemerocampa pseudotsugata) infestations remained endemic on white fir in CALIFORNIA and a new 3,000-acre infestation was discovered in stands of white fir in the San Mateo Mountains of NEW MEXICO. ZIMMERMAN PINE MOTH (Dioryctria zimmermani) and D. cambiicola caused extensive damage to red pines of all ages on parts of the Cutfoot Sioux Experimental Forest near Cass Lake, MINNESOTA; and D. abietella and, to a lesser extent, Barbara colfaxiana caused major damage to the light to moderate crop of Douglas-fir cones in CALIFORNIA. PANDORA MOTH (Coloradia pandora) was reported heavy on about 15,000 acres of lodgepole pine in northwestern UTAH, but the infestation of this species along the COLORADO-WYOMING border decreased in intensity. Damage by larvae of an OLETHREUTID (Laspeyresia fletcherana) increased in Douglas-fir Christmas tree stock growing on the Kootenai National Forest in MONTANA and another olethreutid, Eucosma gloriola, commonly caused damage to Scotch and white pines in eastern OHIO. SAWFLIES of conifers were of considerable importance during 1960, but suppression of infestations was quite limited. A VIRGINIA PINE SAWFLY (Neodiprion pratti pratti) caused extensive defoliation during the year. In VIRGINIA and NORTH CAROLINA, noticeable defoliation occurred on 2,000,000 gross acres. This was the fifth year defoliation has occurred in Virginia and the third in North Carolina. Two small infestations of this sawfly were reported on shortleaf pine near Athens, OHIO. N. pratti paradoxicus defoliated pitch pine extensively in Plymouth County, MASSACHUSETTS, and in NEW JERSEY, south of Trenton. RED-HEADED PINE SAWFLY (N. lecontei) was the most serious sawfly in MICHIGAN, WISCONSIN and MINNESOTA. Outbreaks occurred on 3,500 acres of red and jack pine in the northwestern part of Michigan's Lower Peninsula; in the New Philadelphia area of OHIO; near De Ridder, LOUISIANA; and in certain localities of NEW YORK. Infestations of N. excitans were widespread, but spotty, on industrial lands in southern Polk County and western Hardin County, TEXAS; and the sawfly defoliated shortleaf pines locally in Paulding County, GEORGIA. WHITE-PINE SAWFLY (N. pinetum) was found in small numbers in most white pine plantations in eastern OHIO and EUROPEAN PINE SAWFLY (N. sertifer) was light to moderate on red and Scotch pine throughout most of Ohio, with the heavier concentrations occurring in the central and eastern parts of the State. Infestations were also reported on Austrian pine in the following counties of IOWA: Lucas, Monroe, Jefferson and Van Buren. European pine saw- fly also attacked hard pines, notably red pine, in NEW YORK and southern CONNECTICUT, and RED-PINE SAWFLY (N. nanulus nanulus) defoliated pitch pine in Plymouth, MASSACHUSETTS. In the Intermountain and northern Rocky Mountain States, two species, determined as N. fulviceps complex and N. nanulus contortae, defoliated overstory lodgepole pine in the Little Rocky Mountains, near Zortman, MONTANA, since 1958. The severity of the outbreak declined in 1960. An outbreak of N. edulicolus, which has been underway in stands of pinyon pine near Pioche, NEVADA, during the past few years, decreased in 1960. = M/S) = Infestations of N. taedae linearis were light and scattered on shortleaf pine throughout southeastern MISSOURI and scarce in LOUISIANA and ARKANSAS. HEMLOCK SAWFLY (N. tsugae) populations declined sharply in the hemlock-spruce stands in southeast ALASKA late in the larval feeding period of 1960. INTRODUCED PINE SAWFLY (Diprion similis) caused heavy defoliation of white and jack pines in several areas of MINNESOTA and MICHIGAN, and heavy defoliation was noted on extensive acreages in WISCONSIN. The sawfly was observed lightly feeding on white pine during the late summer and early fall in Lake County, OHIO, and it defoliated white and red pines in central CONNECTICUT and eastern MASSACHUSETTS. EUROPEAN SPRUCE SAWFLY (D. hercyniae) and YELLOW-HEADED SPRUCE SAWFLY (Pikonema alaskensis) were both common in MAINE. LARCH SAWFLY (Pristiphora erichsonii) continued active in stands of western larch in the Blackfoot River drainage, northeast of Missoula, MONTANA, and defoliation by this species was moderate to severe throughout most of the tamarack stands in the Lake States. In northern MINNESOTA, complete stripping was more spotty than previously noted. Farther south, noticeable defoliation was reported as far as central Pine County. In west central WISCONSIN, top- killing was evident in many of the defoliated stands. SEED CHALCIDS (Megas- tigmus spp.) caused moderate to heavy losses in white fir in CALIFORNIA. LODGEPOLE NEEDLE MINER (Evagora milleri) continued in outbreak proportions in lodgepole pine forests of the southern Sierra of CALIFORNIA. The most serious infestation was one that has been in progress for more than a decade in the Tuolumne River drainage, Yosemite National Park. Upwards of 60,000 trees remained infested in the park, and tree killing due to the needle miner alone, and to it in combination with mountain pine beetle, has been severe. A needle miner, closely related to this species, continued to defoliate lodgepole pines locally in Mono County, California. Populations were very heavy, but tree mortality was negligible. Infestations of lodgepole needle miner increased in severity in the lodgepole pine forests of the Intermountain States since 1957. Epidemic centers exist on the Targhee, Sawtooth and Caribou National Forests, IDAHO, and on the Bridger National Forest, WYOMING. Infestations in 1960 in the Intermountain States were epidemic on over 200,000 acres. An infestation was also reported near Zortman, MONTANA. The outbreak of an unidentified NEEDLE MINER (Argyresthia sp.) which developed on ponderosa pine on the Warner District of the Fremont National Forest, OREGON, during 1958, increased markedly in extent and severity in 1960. However, no controls were needed. WHITE-FIR NEEDLE MINER (Epinotia meritana) was serious in stands of white fir in southern UTAH where an increase in population was observed. Aerial treatments and heavy parasitism reduced the outbreak. An OLETHREUTID (Petrova albicapitana) , which is not normally considered an important forest pest, reached outbreak proportions and reduced over 3,000 acres of jack pine on the Upper Peninsula of MICHIGAN to a noncommercial stand. The infested area appeared to be increasing. Damage by the BALSAM WOOLLY APHID (Chermes piceae) in Pacific silver fir stands continued to decline in WASHINGTON and OREGON. Tree killing, especially in Washington, reached the lowest level recorded since the infestation flared up in 1954. Discovery of an aggressive |population on this host on the Little River Ranger District of the Umpqua National Forest, Oregon, extended the southern boundary of known infestation in the region. Four species of intro- duced foreign insect predators now appear to be established in the area. An infestation of balsam woolly aphid, which was discovered only a few years ago, killed approximately 6 percent of the Fraser fir trees as of 1960 ina 22,000-acre area of Mt. Mitchell, NORTH CAROLINA; and the aphid was a serious pest of balsam fir in the coastal area of MAINE as well as inland at the — Shs) Penobscot Experimental Forest. In MONTANA, a heavy population of COOLEY SPRUCE GALL APHID (C. cooleyi) was reported on needles of Douglas-fir east of Seeley Lake, and the aphid was abundant on ornamental spruce trees near Missoula. A light to moderate outbreak of SPRUCE APHID (Aphis abietina) on Sitka spruce on the OREGON coast in 1959 subsided to normalcy in 1960. PINE LEAF APHID (Pineus pinifoliae) severely damaged white pine in MAINE, with the seriously infested area being between Lincoln and Topsfield and extending southward to the sea. Less extensive, but locally severe infestations, occurred in the upper Connecticut River Valley in VERMONT and NEW HAMPSHIRE. Effects of this infestation, which dated from 1957, appeared to be more apparent than in prior years. PINE NEEDLE SCALE (Phenacaspis pinifoliae) has weakened and killed ponderosa pine in a number of places in OREGON and WASHINGTON during the past several years. The principal infestations in 1960 were near Hood River and The Dalles, Oregon, and in the lower Wenatchee Valley and lower Klickitat River drainage in Washington. BLACK PINE LEAF SCALE (Aspidiotus californicus) continued to cause damage to ponderosa and sugar pines in CALIFORNIA, and approximately 2,000 acres of jack pine in Polk County, WISCONSIN, were heavily infested. The scale insect also caused yellowing of shortleaf pine foliage at Jamestown, TENNESSEE. A RED-PINE SCALE (Matsucoccus resinosae) was discovered in NEW JERSEY for the first time -- in 160 acres of watershed planting around the Wanague Reservoir in the north central part of the State. Eradicative steps were undertaken. The SARATOGA SPITTLEBUG (Aphrophora saratogensis) potential for damage to red pine plantations at severl locations in WISCONSIN and Upper MICHIGAN was high in 1960, and damage was averted by treating some 2,600 acres on national forests in Wisconsin and Michigan. Approximately 1,600 acres of State and private lands in Wisconsin were also treated. Populations of a MEALYBUG (Puto sp.) continued at epidemic levels within Engelmann spruce stands in UTAH. The infestations occurred in three separate areas, totaling approximately | 60,000 acres. Mortality of Engelmann spruce reproduction was noticeable within the older infestations. A MIDGE (Contarinia sp.) caused damage to the light to moderate crop of Douglas-fir cones and red fir suffered heavily from SEED MAGGOTS (Earomyia spp.) in CALIFORNIA. An outbreak of an unidentified NEEDLE MIDGE was found on Douglas-fir between Newport, WASHINGTON, and Rexford, MONTANA, where a similar infestation was found in 1950. Christmas trees ready for harvest were badly damaged an the Lolo and Kootenai National Forests and the Flathead Indian Reservation. An epidemic of a PINE RESIN MIDGE (Retinodiplosis sp.),that caused severe damage to lateral branch tips in numerous ponderosa pine plantations over the Northern Rocky Mountain States in 1959, subsided in 1960. A SPIDER MITE (Oligonychus milleri) occurred in outbreak numbers in pine stands over the vast coastal area from NORTH CAROLINA into FLORIDA. Adults were numerous in June. Extensive outbreaks of this mite on pine have been reported in previous years in the Southern States. TEXAS LEAF-CUTTING ANT (Atta texana) destroyed many new pine seedlings throughout its range in east TEXAS and west central LOUISIANA. Of the various defoliators of hardwoods reported during 1960, ELM SPANWORM (Ennomos subsignarius) was one of the most important. Defoliation by elm spanworm was severe over large acreages in GEORGIA, TENNESSEE and NORTH CAROLINA. The infestation, encompassing a gross area of 1,670,000 acres, was the first reported outbreak of these dimensions in the Southeast since 1878. Oaks and hickories growing on ridgetops have been most severely affected. Nearly 200,000 acres of such stands were moderately to severely defoliated. Areas of heavy defoliation spread in 1960 to the north and east into previously uninfested forests. At the same time, defoliation decreased in severity in other areas. = Qeul o Extensive defoliation of oaks and other hardwood species was observed in south central KENTUCKY in June. Damage to red oak was particularly heavy in Wayne County, with several stands of 1,000 acres or more being completely stripped. The total area of defoliation through- " out Wayne and adjacent counties exceeded 100,000 acres. Damage in Kentucky was believed to be caused primarily by LEAF ROLLERS and two or more species of LOOPERS. The identified species of insects collected from the Kentucky defoliated area were BUCK MOTH (Hemileuca maia), a NOCTUID (Morrisonia confusa) , a SPHINGID (Deidamia inscriptum) and elm spanworm, ELM SPANWORM ==} 1960 ) ict DEFOLIATION WESTERN OAK LOOPER (Lambdina fiscellaria somniaria) almost completely defoliated Oregon white oak on approximately 2,080 acres west of Monmouth, OREGON, during the early summer. The trees refoliated later. Extent of elm spanworm defoliationin Georgia, NorthCarolina, GREAT BASIN TENT CATERPILLAR (Malacosoma and Tennessee depicted by shaded areas on map. fragile) has occurred in outbreak numbers in aspen over large areas in northern NEW MEXICO and southern COLORADO for the past decade. Beginning in 1958 and continuing in 1959, larval populations were reduced by natural factors. New infestations were reported on about 100,000 acres in northern New Mexico in 1960 and natural control was negligible. In southern Colorado, infestations continued on a downward trend. FOREST TENT CATERPILLAR (M. disstria) popula- tions were the lowest on record in the Lake States in several years, but the pest severely defoliated water tupelo, blackgum, sweetgum and other bottomland hardwoods in extensive areas of LOUISIANA and ALABAMA during April and May. In Louisiana, areas immediately west of New Orleans and along the Atchafalaya Basin, about 500,000 acres were completely defoliated. An additional 1,000,000 acres in localized areas had some defoliation In the Alabama River Valley, where an outbreak had been underway since 1953, the total area of infestations was esti- mated at more than 1,000,000 acres, of which 56,000 were heavily defoliated. The forest tent caterpillar was also in outbreak status in hardwood forests in MARYLAND, PENNSYLVANIA and NEW YORK. Heavy feeding occurred in Carroll, Wash- ington and Frederick Counties, Maryland; but the extent of feeding was reduced there as well as in WEST VIRGINIA. Heavy feeding occurred in Cumberland County, Pennsylvania, and light feeding in Dutchess and Columbia Counties, New York. Over 5,000 acres of oak and other hardwoods were 90 to 100 percent defoliated in one New York locality. The parasite, Sarcophaga aldrichi, and virus and bacterial diseases helped reduce populations in the Northeast. EASTERN TENT CATERPILLAR (M. americanum) was abundant in NEW YORK, PENNSYLVANIA and WEST VIRGINIA. Tite SGT Gia ana GYPSY MOTH (Porthetria dispar) control was continued in 1960 in the Northeastern States. The various State and Federal programs covered 19,000 acres in NEW YORK, 1,800 acres in MASSACHUSETTS, 20,000 acres in CONNECTICUT, and 2,400 acres in NEW JERSEY. Some 50,000 acres of defoliation were mapped by aerial surveys in the Northeast during 1960; this represents an increase over 1959. Acres defoli- ated, as reported by the various states, were 6,000 in Maine, 4,500 in New Hampshire, 6,000 in Vermont, 15,000 in Connecticut, 150 in Massachusetts, and 16,500 in New York. About 4,500 acres in New York were 75 to 100 percent defoli- ated. No moths were trapped in MICHIGAN in 1960. Hardwood forests on approximately 25,000 acres of the Jefferson National Forest, VIRGINIA, were severely defoliated by FALL CANKERWORM (Alsophila pometaria). In addition, heavy defoliation was reported on the George Washington National Forest, = SEH = Giles County, Virginia, and on two small tracts of timber near Hot Springs, NORTH CAROLINA. Fall cankerworm and SPRING CANKERWORM (Paleacrita vernata) defoliated large areas in CONNECTICUT and PENNSYLVANIA. SPINY OAKWORM (Anisota stigma) , ORANGE-STRIPED OAKWORM (A. senatoria) , YELLOW-NECKED CATERPILLAR (Datana ministra) and VARIABLE OAK LEAF CATERPILLAR (Heterocampa manteo) stripped oaks on thousands of acres in localized areas of ARKANSAS, TEXAS and LOUISIANA during the late summer and fall. A LEAF ROLLER (Argyrotoxa Semipurpurana) caused severe defoliation over extensive areas in southwestern MASSACHUSETTS, northwestern CONNECTICUT and NEW YORK. Black, red, scarlet and pin oaks were attacked. Orange-striped oakworm and RED-HUMPED OAKWORM (Symmerista albifrons) were locally abundant in CONNECTICUT and NEW YORK. FALL WEBWORM (Hyphantria cunea) was prominent in the Northeast coincident with its general abnormal abundance all over the Eastern United States. Also in the Northeast, infestations of SOLITARY OAK LEAF MINER (Cameraria hamadrya- della) and GREGARIOUS OAK LEAF MINER (Cc. cincinnatiella) were widespread. A LEAF MINER (Phyllocnistis populiella) continued to inflict extensive damage to aspen stands in western WYOMING and eastern IDAHO, and BEECH SCALE (Crypto- coccus fagi) was found farther north than ever before in NEW YORK -- in Arietta, Hamilton County. ASIATIC OAK WEEVIL (Cyrtepistomus castaneus) increased markedly in numbers in southern WEST VIRGINIA. It was also found statewide in PENNSYLVANIA and in Allegany and Washington Counties, MARYLAND. rey) Flo inh Pt P) Head rey EAN hi \ V PEST CONTROL OI | ey NICULTURAL RESEARCH SERVICE AGRICULTURAL RESEARCH SERVICE PLANT PEST CONTROL DIVISION SURVEY AND DETECTION OPERATIONS The Cooperative Economic Insect Report is issued weekly as a service to American Agriculture.

FIO IIR IK KE Reports in this issue are for week ending October 20 unless otherwise indicated. = Chew o WEATHER OF THE WEEK ENDING OCTOBER 23 A week of dry, sunny weather with warm days and cool nights in the southern por- tion of the Nation favored harvesting operations, but increased the need for moisture in some dry southeastern areas. In northern areas, general precipita- tion moved from the upper Great Plains to the Atlantic coast on the 18th, 19th and 20th, and rains fell along the North Atlantic coast during the weekend. Precipitation fell in northern areas of the Far West during the latter part of the period. In the Southeast, many stations have had no rain at all for periods ranging from 3 to 6 weeks, while many others report only insignificant amounts or amounts much less than needed. Soil moisture is short to very short in South Carolina,Georgia, and the western, northern and central portions of Florida. Precipitation in northern areas east of the Rockies on the 18th to 20th was generally light. A storm which developed off the middle Atlantic coast, however, brought extremely heavy precipitation to Virginia and southern Maryland during the weekend. Totals in Virginia ranged up to nearly 12 inches in central portions and from 2 to 9 inches in the remainder of the State, and flooding occurred along some streams. Over 3 inches of rainfall was reported in southern Maryland. Light to heavy snow fell in the lower Appalachians. A few inches of snow were reported in southwestern Virginia, but in Nicholas County, West Virginia, a fall of 23 inches was reported. The snow was wet and heavy and caused considerable damage to power and communication lines and trees. Weekend storms off the North Atlantic coast brought strong northeast winds and gales to coastal New England. Heavy sea and surf caused extensive damage to small boats and other property along the shore. Precipitation in the Far West was generally light, with some snow in the central and northern Rockies, but some heavy amounts of moisture for the season were reported in southern Montana. Temperatures in northern areas east of the Rockies were below normal at the beginning and end of the week and above during the middle part of the period. Maxima in the 80's were recorded in North Dakota and Minnesota on the warmest days, and 89° at Sioux City, Iowa, on the 17th, was the highest temperature ever recorded there so late in the season. The weekend was abnormally cold in the Pacific Northwest. Temperatures for the week averaged well below normal in the Pacific Northwest and in southern areas east of the Great Plains, and near to slightly above normal elsewhere. (Summary supplied by U. S.

FOREST, ORNAMENTAL AND SHADE TREE INSECTS SOUTHERN PINE BEETLE (Dendroctonus frontalis) - TEXAS - Epidemic continues serious in southeast counties. Aerial inspection during mid-September detected only 40 new spots, a definite decrease in number found previously during summer inspections; however, 65 new spots located September 26. This increase in late September is reverse of previous year's experience. Hurricane Carla brought rains of 4-10 inches to epidemic area, thus hampering control operations.

SPRUCE BUDWORM (Choristoneura fumiferana) - MAINE - Egg mass survey in Squapan Lake area, Aroostook County, indicates heavy deposition on fir in general area; heavy defoliation of fir in area noted earlier in year. Parasitism of larvae not sufficient to effect natural control. Isolated heavy infestation at Bancroft, 30 miles south of Houlton, Aroostook County, detected late in season, but total size not yet determined. Possible control in 1962 will be based on complete analysis, later this fall, of egg mass survey data and present condition of trees in Squapan Lake area. (Northeast. For. Pest Rpt., Oct. 16). EUROPEAN PINE SHOOT MOTH (Rhyacionia buoliana) - WEST VIRGINIA —- Common on red pine in 4 northern panhandle counties. (Northeast. For. Pest Rpt., Oct. 16).

(Northeast. For. Pest Rpt., Oct. 16). PINE SAWFLIES - An outbreak of Neodiprion pratti pratti has occurred in MARYLAND, VIRGINIA and NORTH CAROLINA for past few years. Defoliation continued extensive on Virginia, pitch and shortleaf pines during 1961, but was less severe than in 1960. Egg surveys in these states should indicate if outbreak is finally declin- ing. Egg surveys of 1960 indicated 1961 defoliation would be severe; however, protracted cool, wet weather decimated larval populations in many places early this year by interfering with development as well as permitting high incidence of disease. Even where larval populations remained high, interference with development was so great defoliation was not in proportion to larval numbers. Natural control forces were documented in 1961 by study of pupal stage in Virginia. Studies were made in stands moderately to heavily defoliated in 1960. Biological agents, including mites, ants and parasites, effected nearly 90 percent control of pupae. (Northeast. For. Pest Rpt., Oct. 16).

VELVETBEAN CATERPILLAR (Anticarsia gemmatalis) - SOUTH CAROLINA - Charleston (10/9-15) - 59. - 996 - Summary of Insect Conditions - 1960 (continued from page 982) ORNAMENTAL AND SHADE TREE INSECTS Ornamental Insects: As in 1959, BAGWORM (Thyridopteryx ephemeraeformis) was the most frequently reported and most widespread of the lepidopterous species infes-— ting ornamentals during the 1960 season. The pest appeared to be spreading in southern Fairfield County, CONNECTICUT, where some serious, localized infesta- tions were observed. Injury was rather heavy in DELAWARE during 1960, with several possible deaths of ornamentals occurring in northern New Castle and central Kent Counties. First instars were initially noted on cedars and arborvitae in Kent County during May. Larvae became common to abundant on mimosa, pines, dogwood, sycamore and many other hosts throughout the State, development being completed in most areas of Delaware by mid-August. Infesta- tions were common, but somewhat below normal, on evergreens in all sections of MARYLAND and were prevalent on conifers throughout VIRGINIA. Bagworm occurred mainly in the northern Piedmont in NORTH CAROLINA, where it caused defoliation and mortality, and was quite prevalent on various coniferous shrubs in TENNESSEE, Infestations appeared in June on arborvitae in Jefferson Davis Parish and on pyracantha in Orleans Parish, LOUISIANA, and were rather heavy and general over TEXAS during 1960. Bagworm caused heavy damage to evergreens in most areas of OKLAHOMA, the loss of shrubs, because of untreated infestations, being not un- common during the summer in many communities. Minor infestations occurred on Many varieties of plants in MISSOURI during the season. As in 1958 and 1959, bagworm was a problem on junipers, arborvitae, Norway spruce and some deciduous trees and shrubs in KANSAS. The pest was more serious in the State because of the appearance of new larval populations in late June, July and August on ever- greens on which control was obtained for the first population in May. Popula- tions returned to normal in INDIANA during the 1960 season, being important on both deciduous and evergreen plants. Another PSYCHID (Apterona crenulella) extended its known range in CALIFORNIA into Butte and El Dorado Counties. Although heavy populations occurred without noticeable damage, the snail-like mud cases were a nuisance. Larvae of AZALEA LEAF MINER (Gracilaria azaleella) were common and active in azaleas in DELAWARE during late May and early June and again in late August and early September. LILAC LEAF MINER (G. syringella) was extremely common in MONTANA during 1960, both east and west of the Continental Divide. Several noctuids were reported troublesome and damaging during 1960. IRIS BORER (Macronoctua onusta) damaged plants in South Kingston, Washington County, RHODE ISLAND, on August 9, and was troublesome in various hosts over IOWA during the 1960 season. CORN EARWORM (Heliothis zea) was observed feeding on chrysanthemum in New Orleans, LOUISIANA, in September. LILAC BORER (Podosesia syringae syringae) was reported from numerous areas of CONNECTICUT during 1960 and was troublesome in various hosts over IOWA. Unspeci- fied BORERS in various ornamentals, especially lilac, dogwood and rhododendron, appear to be a problem that is becoming more intensive in PENNSYLVANIA. Various other lepidopterous pests were reported from several sections of the Nation during 1960 as damaging or infesting various ornamentals. In New England, infestations and damage by ARBORVITAE LEAF MINER (Argyresthia thuiella) were heavy on arborvitae in Kennebec County, MAINE, and SATIN MOTH (Stilpnotia salicis) caused complete defoliation of some ornamental poplars in Berlin, Coos County, NEW HAMPSHIRE. In New Castle County, DELAWARE, larvae of RED-HUMPED CATERPILLAR (Schizura concinna) were very common on dogwood in late August, causing moderately heavy feeding injury, and larvae of a SPHINGID (Dolba hylaeus) attacked Japanese and English holly in one area of the county during early July. = 880 = Larvae of another SPHINGID (Pseudosphinx tetrio) were collected on frangipani in FLORIDA at Sarasota,Sarasota County, on August 28. This is first record of this species for Sarasota County and is the northernmost record for the State. caused considerable defoliation of ornamental passionvines in CALIFORNIA, but did not damage commercial plantings of this host. In ALASKA, an undetermined species of LEAF ROLLER rolled leaves of delphiniums in Cook Inlet and Tanana Valley areas during 1960, and a SPEAR-MARKED BLACK MOTH (Eulype hastata) appeared to be diminishing in numbers, although it remained numerous in some areas of the State. In the extreme western portion of the Nation, a NYMPHALID (Agraulis vanillae) Several species of Coleoptera were reported troublesome on ornamentals during 1960. JAPANESE BEETLE (Popillia japonica) was reported more often than other coleopterous species and was of considerable concern in a number of Eastern States. It was generally more abundant in VERMONT, especially in the Windsor, Westminster and Bradford areas. In RHODE ISLAND, mature larvae were observed forming pupal cells in soil at Narragansett, Washington County, on June 3. Adults were observed in North Providence and Smithfield, Providence County, on June 29, and by July 6 complaints were numerous from all areas of the State. Adults and larvae were numerous in some localized areas of CONNECTICUT. Most of these locations were in new developments, formerly fields or brush areas, where the entire areas were regraded. Larval damage to these new lawns was extensive, with other local vegetation also being damaged. Damage by Japanese beetle in northwestern PENNSYLVANIA was more severe than usual during 1960 and numbers in MARYLAND were generally up over those of 1959, with numerous requests for control information from homeowners in suburban sections of the State. Japanese beetle caused considerable concern throughout VIRGINIA during the spring and summer of 1960, adults feeding on a variety of forest and shade trees, defoliating grapes and Virginia creeper in some areas and heavily attack- ing linden and horsechestnut. Heavy adult flights of ASIATIC GARDEN BEETLE (Autoserica castanea) occurred in the Narragansett area of Washington County, RHODE ISLAND, during mid-May and heavy numbers were observed on American holly during July at Hyattsville, Prince Georges County, MARYLAND. Moderate numbers of ROSE CHAFER (Macrodactylus subspinosus) caused moderate damage to many plant species in areas of Androscoggin and Sagadohoc Counties, MAINE, and were abundant in Chittenden and Washington Counties, VERMONT. Adults were abundant on rose locally in Washington County, RHODE ISLAND, during early June. BLACK VINE WEEVIL (Brachyrhinus sulcatus) infested Taxus in many communities of CONNECTICUT during 1960, feeding upon the roots and foliage, and larvae caused the loss of 60 percent of small rhododendron plants in pots at a RHODE ISLAND nursery. POPLAR-AND-WILLOW BORER (Sternochetus lapathi) caused heavy damage locally on pussy willow in the Fiskeville area of Providence County, Rhode Island. Adults of a JAPANESE WEEVIL (Pseudocneorhinus bifasciatus) fed heavily on a variety of shrubs in northern New Castle County, DELAWARE, in early September and another JAPANESE WEEVIL (Calomycterus setarius) and P. bifasciatus attacked deciduous ornamentals in central and southern sections of MARYLAND during July and August. Adults of ROSE CURCULIO (Rhynchites bicolor) fed on tips of roses in Narragansett, Washington County, RHODE ISLAND, in late June. In UTAH, roses were damaged by rose curculio and another WEEVIL (Brachyr- hinus sp.). A LILAC WEEVIL (Brachyrhinus meridionalis) was damaging in Ravalli and Missoula Counties, MONTANA, during the 1960 season. Several other species of Coleoptera were reported troublesome during 1960. A NITIDULID (Conotelus mexicanus) was extremely abundant on flowers, such as roses and chrysanthemums, in Southern counties of NEW MEXICO. PINE COLASPIS (Maeco- laspis pini) caused considerable damage to ornamental pine, spruce and cypress in East Baton Rouge, Jefferson Davis, Acadia and West Feliciana Parishes, LOUISIANA, during May. However, there were no infestations on commercial stands Of pine in the State. Adults of a BLISTER BEETLE (Macrobasis sp.) infested orna- mental mountain ash in South Kingston, RHODE ISLAND, during late June. = 998 - Various species of APHIDS were reported infesting ornamentals during 1960 in several states. Among these were SNOWBALL APHID (Anuraphis viburnicola) which occurred on viburnum in the East Greenwich area of Kent County, RHODE ISLAND, during early June and ROSE APHID (Macrosiphum rosae) which became moderately abundant on roses in Narragansett, Washington County, late in the summer. CHRYSANTHEMUM APHID (Macrosiphoniella sanborni) was abundant on chrysanthemums in northern New Castle County, DELAWARE, in early May. Another APHID (Cinara tujafilina) was quite common on arborvitae in most parts of OKLAHOMA during late winter and early spring. Light numbers again appeared the following October in the Stillwater area, Payne County, and moderate populations were reported in the south central area of the State during late December. Popula- tions of SPIREA APHID (Aphis spiraecola) were below normal in UTAH during 1960, but POTATO APHID (Macrosiphum euphorbiae) did cause some damage to ornamentals. GREEN PEACH APHID (Myzus persicae) was damaging to many ornamentals and trees in CALIFORNIA in the early part of 1960, persisting over a much longer period of time than normal in some areas of the State. A SPRUCE GALL APHID (Chermes sp.) was common on spruces used as ornamentals in the Juneau area of ALASKA during the 1960 season. Infestations of several species of APHIDS were heavy on ornamental plants and roses in ARIZONA during the spring of 1960. Moderate to heavy populations of various species occurred on ornamentals over NEVADA, and curled foliage of ornamental flowering hawthorn in UTAH in some instances. Several species infested ornamentals in MISSOURI and various species were abundant on rose, chrysanthemum, pyracantha and tulip, as well as poplar, oak and pine, in MARYLAND during the season. Heavy infestations of RHODODENDRON LACE BUG (Stephanitis rhododendri) occurred on rhododendron in RHODE ISLAND during mid-July at Johnston, Providence County. Adults of AZALEA LACE BUG (S. pyrioides) were abundant on azaleas in Sussex County, DELAWARE, during mid-May, causing moderately heavy damage. Several species of LACE BUGS were primary pests of ornamentals in CONNECTICUT during 1960 and were again abundant on azaleas, hawthorn, rhododendron, oaks and other ornamentals in MARYLAND during the summer of 1960. Adults of a SPITTLEBUG (Prosapia bicincta)* were rather abundant, with noticeable injury to new growth of American holly during mid-July in northern New Castle County, DELAWARE. ROSE LEAFHOPPER (Edwardsiana rosae) conspicuously discolored foliage of culti- vated roses throughout UTAH during the 1960 season and became numerous on spirea at Logan and Ogden in the fall. VIRGINIA-CREEPER LEAFHOPPER (Erythroneura zZiczac), E. elegans and other species of LEAFHOPPERS damaged Virginia creeper foliage during late summer and fall in many counties in Utah, leaves frequently being killed before late August. Another LEAFHOPPER (E. aclys) was again abun- dant on redbud throughout INDIANA, most ornamental redbuds being yellow by mid-September. COCCIDS were reported as infesting and damaging various ornamentals during the 1960 season. Heavy infestations of OYSTERSHELL SCALE (Lepidosaphes ulmi) occurred in Androscoggin County, MAINE, and damage was moderate to lilacs. In RHODE ISLAND, crawlers were first observed about June 13. The coccid was injur- ious to ornamental maples and lilac in MARYLAND and was reported to have been more plentiful than normal in nurseries in WISCONSIN during the 1960 season. The pest was more numerous this year in WYOMING, damaging many species of trees and shrubs and frequently caused injury in UTAH, especially to ash, poplar, willow and lilac. First crawlers of JUNIPER SCALE (Diaspis carueli) appeared about June 13 in Providence County, RHODE ISLAND, and the pest was damaging to ornamental junipers in several localities of UTAH during the season. PINE NEEDLE SCALE (Phenacaspis pinifoliae) infested many plantings of pine and spruce in IOWA during 1960 and was injurious to various ornamental pines in MARYLAND. * Fennah, R. G. 1948. Ann. and Mag. Nat. Hist. Ser. 12, 1(9) :606. = EE = Infestations of EUONYMUS SCALE (Unaspis euonymi) were very heavy on some euonymus in northern Kent County, DELAWARE, in mid-May. The pest was also injurious to this host in MARYLAND and attacks were heavy in NORTH CAROLINA. In MARYLAND, SAN JOSE SCALE (Aspidiotus perniciosus) was injurious to pyracantha and other orna- mentals and WHITE PEACH SCALE (Pseudaulacaspis pentagona) damaged privet, lilac and ornamental cherry. White peach scale also occurred frequently on ornamental and shade trees in NORTH CAROLINA. The collection of CAMPHOR SCALE (Pseudaonidia duplex) on camellia at Gainesville, Alachua County, FLORIDA, on November 16,1960, constitutes a new State record. During December, the scale was also collected on camellia or azalea in Alachua, Pinellas, Escambia, Hillsborough, Nassau and Polk Counties, for new county records. Camphor scale has previously been reported from Louisiana and is known to occur in the Hawaiian Islands, India, Philippine Islands and Argentina. OLEANDER SCALE (Aspidiotus hederae) infested many ornamentals over CALIFORNIA during the 1960 season, heavy populations making plants unsightly rather than causing damage. CALIFORNIA RED SCALE (Aonidiella aurantii) has become wide- spread in California and now attacks many ornamental shrubs and trees. TEA SCALE (Fiorinia theae) caused considerable damage to citrus trees and camellia plants in Orange County, TEXAS, and isolated infestations were found on camellias during September in LOUISIANA. FLETCHER SCALE (Lecanium fletcheri) continued to be a problem on junipers and arborvitae in IOWA during 1960 and infested Taxus spp. in CONNECTICUT during the season. This scale also occurred on arborvitae in Prosser, WASHINGTON; it was previously recorded at Pullman in 1958. COTTONY- CUSHION SCALE (Icerya purchasi) caused moderate damage over TEXAS during the 1960 season. Light infestations occurred on many ornamental shrubs in CALIFORNIA, with plants being occasionally damaged. Generally, these shrub infestations act as breeding locations for VEDALIA (Rodolia cardinalis). Various other COCCIDS were reported as damaging or troublesome from several of the states. Hatch and crawler dispersal of Lepidosaphes yanagicola on euonymus and of Pulvinaria floccifera on yew were both observed in the Warwick area of RHODE ISLAND on June 29. Various species of coccids were generally abundant in PENNSYLVANIA during the 1960 season and P. floccifera infested Taxus spp. in CONNECTICUT. In MARYLAND, Ceroplastes sp. was injurious to hemlock and holly and Fiorinia externa was injurious to hemlock and yew. In NORTH CAROLINA,Ceroplastes sp., near ceriferus, was frequently observed on ornamentals, including shade trees. A MEALYBUG (Geococcus coffeae) was collected on philodendron at Lockhart, Orange County, on September 27, for a new locality record in FLORIDA. The species was first reported in the United States at Apoka, Orange County, in 1958 and again at Oviedo, Seminole County, in 1959. Another MEALYBUG (Trionymus diminutus) occurred on nursery ornamentals and lilies in northern CALIFORNIA during 1960 and heavy infestations of Chionaspis ortholobis occurred on snowbrush ceanothus in the Mammoth Lakes area of Mono County. Continuous infestations of this latter species can seriously damage browse and undercover plants in this area. Lecanium Kunoensis infested pyracantha in the Chico area of Butte County, California, during the season, eradicative treatment being applied to infested plants. In San Diego Courty, heavy populations of Parlatoria pittospori occurred on Pittos- porum sp. and Melaleuca sp. and were medium on Hakea sp. in the area of the city of San Diego. Varied infestations of Stomacoccus platani occurred over California during 1960, but the species was not as prevalent as in previous years. Asterole- canium arabidis occurred in San Joaquin, Santa Cruz, Mendocino and Butte Counties. The species is an eradication pest in California when occurring in nurseries, and it severely damages oaks and some shrubs. This pit scale occurred for the first time on sage during the 1960 season. THRIPS were of some concern in a few areas of the Nation during 1960. General infestations of CUBAN-LAUREL THRIPS (Gynaikothrips ficorum) occurred on Ficus retusa in San Diego and other local areas of San Diego County, CALIFORNIA. Another THRIPS (Frankliniella occidentalis) was severe on many yard and street = iO) = ornamentals and general on native plants in California, causing considerable damage during the season. Damage by GLADIOLUS THRIPS (Taeniothrips simplex) was about normal in UTAH, while undetermined species of THRIPS caused some damage to roses and were again abundant in most cultivated and wildflower blossoms in the State during 1960. FLOWER THRIPS (Frankliniella tritici) caused considerable damage to rosebuds in Baton Rouge, LOUISIANA, during May. In RHODE ISLAND, another species of thrips, probably Dendrothrips ornatus, caused drastic damage to a 30-foot privet hedge in Coventry, Kent County, the damage being evident in early July; and Gnophothrips piniphilus caused severe injury to black pine in a nursery in Wakefield, Washington County. In RHODE ISLAND, a moderate infestation of BOXWOOD PSYLLID (Psylla buxi) developed during mid-May on boxwood in Wakefield. WHITEFLIES were minor pests of ornamentals in CONNECTICUT during 1960 and were generally not as prevalent on ornamentals and native plants during 1960 in CALIFORNIA as in previous years. BOXWOOD LEAF MINER (Monarthropalpus buxi) was fairly heavy during 1960 in untreated American boxwood in DELAWARE, where pupation was completed and adults were emerging in early May. Adult flights occurred in RHODE ISLAND in the vicinity of boxwood in the Barrington area of Bristol County during late May. A HOLLY BERRY MIDGE (possibly Asphondylia ilicicola) , a recent insect in CONNECTICUT, was reported as spreading slowly from the general area in which it was first found in the south central part of the State. EUROPEAN EARWIG (Forficula auricularia) was a pest and damaging to yard orna- mentals from April through August in CALIFORNIA in most of the counties north of Santa Barbara, and caused the usual widespread annoyance and some damage about homes and gardens in UTAH. Light numbers were reported in Cumberland County, MAINE, and reports from other areas in the State infested in 1959 indicate the pest made no substantial headway during 1960. Several Hymenoptera were reported as damaging and annoying during 1960. BRISTLY ROSE-SLUG (Cladius isomerus) infested roses in Henderson County, NORTH CAROLINA, during mid-June. Bristly rose-slug and CURLED ROSE SAWFLY (Allantus cinctus) were widespread and abundant in ILLINOIS, causing severe browning and defoliation of roses. Browning and defoliation were especially noticeable in multiflora rose hedges. PEAR-SLUG (Caliroa cerasi) larvae were observed as late as November on ornamental plums in Dane County, WISCONSIN, during 1960. ROSE-SLUG (Endelomyia aethiops) damaged roses in UTAH during the season and two undetermined species of Endelomyia infested roses in MISSOURI. A SAWFLY (Neodiprion sp.) caused considerable defoliation of evergreen plantings in southern and western ILLINOIS, with controls being applied in both areas, and GIANT HORNET (Vespa crabro germana) debarked lilac bushes in a few counties of VIRGINIA during the 1960 season. MITES were also of some concern in various parts of the country during the 1960 season. A buildup of SPRUCE SPIDER MITE (Oligonychus ununguis) occurred on spruce in the vicinity of treated elms in RHODE ISLAND. The species is apparently causing decline and contributing to subsequent death of spruce trees in the neighborhood of the Scituate reservoir in Providence County. In CONNECTICUT; heavy, localized infestations occurred on hemlock, arborvitae, spruce and Taxus spp., but injury was spotty. The species was particularly troublesome on spruce in MARYLAND during the season and was abundant in DELAWARE, causing heavy webbing on spruce trees in late April. In NORTH DAKOTA, infestations were moderate to heavy on spruce, arborvitae and junipers in nursery and home plantings and the pest caused localized damage to ornamental blue spruce in the Portland area of OREGON during the fall months. Heavy populations of spruce spider mite developed on junipers in CALIFORNIA during March. TWO-SPOTTED SPIDER MITE (Tetranychus telarius) occurred in heavy, localized infestations on hemlock, arborvitae, spruce and Taxus spp. in CONNECTICUT during 1960, but injury was spotty. Infestations ranged moderate to heavy on spruce, arborvitae and junipers in nurseries and home plantings in NORTH DAKOTA and the mite was prevalent on trees and ornamentals in WYOMING, inflicting moderate = 1001) = damage in many areas. Very little control was conducted in Wyoming during the past season, except on a small amount of ornamentals. Two-spotted spider mite damaged roses in UTAH during the 1960 season and varied populations developed on many ornamentals in CALIFORNIA, with local infestations becoming quite severe on both yard and street plantings. SOUTHERN RED MITE (Oligonychus ilicis) was very abundant in DELAWARE, with 10-15 per leaf on American holly in northern New Castle County in mid-May, was particu- larly troublesome on holly in MARYLAND during the year and was also very abundant on azaleas in lathhouses during March in Abita Springs, St. Tammany Parish, LOUISIANA. Light to heavy infestations of CLOVER MITE (Bryobia praetiosa) occurred on ivy plantings in the Potter Valley of Mendocino County, CALIFORNIA. Several species of SPIDER MITES were troublesome on various ornamentals in MARYLAND during 1960, especially during hot weather. In FLORIDA, Eotetranychus lewisi was collected on poinsettia at Homestead, Dade County, on November 15, and at Deland, Volusia County, on November 28. This mite can probably be found everywhere poinsettias are grown in Florida, although it was only recently collected in the State. Infestations of undetermined species of spider mites occurred on evergreens in Lincoln County, NEBRASKA, during 1960 and varied from light to heavy on broadleaf and evergreen shrubs and trees in NEVADA, requiring extensive control throughout the latter State. Heavy infestations of undeter- mined species were present on home plantings statewide in ARIZONA throughout the summer and fall of 1960. In CALIFORNIA, Schizotetranychus celarius was heavy on several species of bamboo in the Carmel Valley, Monterey County. Moderate populations of E. lewisi damaged poinsettias in San Diego County. In CALIFORNIA, heavy populations of CYCLAMEN MITE (Steneotarsonemus pallidus) developed on ivy in the Oxnard area of Ventura County and the pest severely injured begonias in a large commercial greenhouse in NORTH CAROLINA during the 1960 season. A buildup of an unspecified species of ERIOPHYID MITE was noted on ash over much of MONTANA during the past year. GARDEN SLUGS were present in heavy numbers and caused annoyance in the Boothbay area of MAINE during 1960, and were also destructive in areas of ALASKA other than the southeastern section where they usually are annoying. BROWN GARDEN SNAIL (Helix aspersa) was recorded for the first time in WASHINGTON, causing considerable damage to flowers in Pacific County. Lawn and Turf Insects: Some additional pests of grasses included FRIT FLY (Oscinella frit) which damaged foliage of turf on golf greens in Fairfield, Hartford and New Haven Counties, CONNECTICUT. Injury was localized in all instances. Infestations of a CHINCH BUG (Blissus leucopterus insularis) were heavy on St. Augustine grass in GEORGIA during 1960. In NEW MEXICO, a MIRID (Orthotylus coagulatus) was very destructive to Tif-green Bermuda grass lawns in the Las Cruces area of Dona Ana County and in Sierra County, and a GRASS BILLBUG (Sphenophorus phoeniciensis) became a problem on Bermuda grass during the summer months in Dona Ana County. A SNAIL (Vallonia pulchella) became locally heavy in lawns in CALIFORNIA during the 1960 season, but apparently was not damaging. GRANULATE CUTWORM (Feltia subterranea) was damaging to dichondra lawns generally in California, with controls required in a few local areas. A WEBWORM (Crambus sperryellus) was also a general lawn pest in California, infestations becoming severe in a few local areas and requiring controls. Infestations of FALL ARMYWORM (Laphygma frugiperda) ranged moderate to heavy on lawns over GEORGIA during the season. = 1002 - Shade Tree Insects: Various species of Lepidoptera were reported during 1960 as infesting and damaging shade trees, the degree of damage depending upon the pest species, as well as the host and geographical area involved. FALL WEBWORM (Hyphantria cunea) was one of the more important species during the season. Populations were considerably above normal in MAINE, damage being found for the most part on roadside brush, although severe damage occurred to untreated orna-— mental and shade trees in many areas. In RHODE ISLAND, larvae were hatched in the Warwick area of Kent County by June 29. Larvae fed on planetrees, boxelder, sycamore, sweetgum and wild cherry throughout DELAWARE, with heaviest infesta-— tions and injury occurring in southeastern Sussex County during late June to early August, as they did the previous year. Fall webworm was very conspicuous over VIRGINIA during the past season, especially on sourwood and persimmon, and was light to moderate in GEORGIA, similar to 1959. Light to medium infestations of fall webworm were common on a wide variety of native trees in the eastern two-thirds of OKLAHOMA again this year, while in KANSAS, many elms were infested early in August, but the populations died out from natural causes. In INDIANA, the fall generation of this pest was unusually heavy in the most southern counties. Larvae first appeared in Racine County, WISCONSIN, the last week of July but webs were scarce throughout the area. How- ever, webs were more evident near Endeavor, Marquette County, although in the State as a whole populations were low. Fall webworm damaged shade trees throughout NEW MEXICO during the 1960 season. Larvae also became a nuisance in many areas where they crawled on walls, walks and entered homes. Damage continued high on trees in Bandalier, Chaco Canyon and Aztec Ruins National Monuments during 1960, where the pest caused complete defoliation in many areas during 1959. Adults began to appear the week ending March 19 at Salem, OREGON, and emergence peaked in early June with over 60 adults collected each night for 10 nights at one blacklight trap. Larval infestations were the heaviest on record in the Willamette Valley. Untreated walnut trees, a common shade tree in most cities and towns in Oregon, were heavily attacked. PINE NEEDLE MINER (Exoteleia pinifoliella) was more abundant on pitch pine in NEW HAMPSHIRE during 1960 than in 1959 and adults of PALE TUSSOCK MOTH (Halisidota tessellaris)were abundant in the light trap in the Kingston area of Washington County, RHODE ISLAND, on July 25. In DELAWARE, larvae of another GELECHIID (Fascista cercerisella) caused heavy injury between webbed leaves of redbud trees in New Castle County during mid-July and larvae of JUNIPER WEBWORM (Dichromeris marginella) heavily webbed leaves of juniper in northern New Castle County in mid-May. Juniper webworm was collected for the first time in FLORIDA at Daytona Beach, Volusia County, on Irish juniper on January 27, 1960. Deter= mination was made by H. W. Capps. Two other WEBWORMS, Salebria afflictella and Tetralopha melanogrammos, were present in Kent County, DELAWARE, in early July on sweetgum trees, causing light injury and again in mid-August in one area of Sussex County where they caused moderately heavy injury. Infestations of these two webworms did not increase over those of previous years in the State. PINE WEBWORM (Tetralopha robustella) was common on young stands of various ornamental pines in several localities of VIRGINIA, and infestations of another WEBWORM (I. asperatella) occurred in the Turkey Run State Park in INDIANA. Several severe infestations of an undetermined WEBWORM occurred at Linton,Emmons County, and at Harvey, Wells County, NORTH DAKOTA, where ornamental cotoneaster plantings were defoliated. During 1960, MIMOSA WEBWORM (Homadaula albizziae) was reported for the first time from Champaign County, ILLINOIS, and continued to spread farther north in INDIANA, infestations being very serious on honeylocust trees in central and southern por- tions of the State. The pest was also quite severe on honeylocust, as well as mimosa, in the southern half of PENNSYLVANIA. The first adult mimosa webworm was noted in northern Kent County, DELAWARE, on June 11, larvae in Kent and Sussex Counties on mimosa by late June and heavy webbing in early July. Second-genera- tion larvae were well advanced by mid-August and webbing was very noticeable in - 1003 - early September. Although injury was severe in Delaware during 1960, the pest was not as heavy as during 1959. As in past years, mimosa webworm was severe on mimosa and honeylocust in most sections of MARYLAND during 1960, infested mimosa in many localities of VIRGINIA and caused considerable defoliation of host trees in TENNESSEE. Infestations ranged light to heavy in GEORGIA during the season. Mimosa webworm was collected in FLORIDA on mimosa at Macclenny, Baker County, on July 19, for a new country record. The pest was first found in Florida in 1958, but has yet to be collected in the peninsular portion of the State. SPRING CANKERWORM (Paleacrita vernata) caused medium damage to live oaks in San Mateo County, CALIFORNIA, as well as causing some damage in OKLAHOMA during the season. Elm, hackberry and locust were so severely attacked in KANSAS commu- nities where dormant sprays were not applied against elm bark beetles that it was difficult to determine when leaves were produced. In NEBRASKA, some damage to foliage of shade trees occurred in the city of Lincoln during early May. A severe population of spring cankerworm defoliated native American elms growing along the Heart River at Belfield, Stark County, NORTH DAKOTA, during June, and light to moderate defoliation occurred on scattered elm trees at Fargo, Cass County, with scattered, light infestations being reported in several other communities. Larvae defoliated trees in central and eastern IOWA during 1960, the infested area covering portions of 5 counties but being less severe than during 1959. Spring cankerworm was very abundant and caused serious defoliation of many elm trees throughout ILLINOIS during April, May and June, and was fairly common on elms in one area of Sussex County, DELAWARE, in mid-April. Many nearly mature larvae of FALL CANKERWORM (Alsophila pometaria) fed heavily on deciduous trees in the Cranston area of Providence County, RHODE ISLAND, in early June, and defoliated large areas of elm, boxwood and other trees in eastern MONTANA during the 1960 season. TENT CATERPILLARS (Malacosoma spp.) caused some damage in OKLAHOMA during the 1960 season and damage and infestations of various species ranged from light to heavy in various other states. Outbreaks of EASTERN TENT CATERPILLAR (M. ameri- canum) were very light in most areas of RHODE ISLAND during 1960, although a moderate outbreak did occur in the East Greenwich area of Kent County during the season. Infestations were very severe in DELAWARE this year, with highest popula- tions occurring in Kent County. Eggs hatched by mid-April, and by late April larval feeding became quite noticeable along roadsides, especially on apple and wild cherry, reaching a peak in early May. Populations were high on wild cherry, crabapple and apple in most sections of MARYLAND during 1960 but were down from those of 1959. Large numbers appeared across TENNESSEE in the spring, being a nuisance mostly after-leaving the webs. The pest caused the usual heavy defolia- tion of wild cherry in GEORGIA during the season, as well as causing some damage to laurelcherry in East Baton Rouge Parish, LOUISIANA. Infestations of eastern tent caterpillar were severe but local in KANSAS during 1960 and the pest was common on apple and black cherry trees during April and May in INDIANA. Eastern tent caterpillar was again on the increase in ILLINOIS during 1960 as was the area of infestation. The species was present throughout the northern and southern portions of the State, but was scarce or absent in the central portion. Wild cherry trees 50-60 feet high were completely defoliated. The pest occurred as far north as Price and Ashland Counties in WISCONSIN during 1960. Infestations were considered normal for all of the State except a section of Rock County, where populations were very heavy. FOREST TENT CATERPILLAR (Malacosoma disstria) damaged maple, ash and apple trees and various shrubs about communities in UTAH during the season and was also a moderate forest and shrub pest in canyons over the State. However, damage during 1960 was much less than that which occurred during the period 1957 through 1959. Also in Utah, GREAT BASIN TENT CATERPILLAR (M. fragile) caused normal injury to poplars in Washington, Kane, Grant and San Juan Counties. On the Pacific coast, - 1004 - CALIFORNIA TENT CATERPILLAR (M. californicum) caused some damage to native oaks in the northern portion of CALIFORNIA during 1960. Infestations of BIRCH SKELETONIZER (Bucculatrix canadensisella) were not as serious in CONNECTICUT during 1960 as in past years. Several species of LEAF MINERS were reported as abundant and injurious in some sections of the Nation during the season. In DELAWARE, mature larvae of Phyllocnistis liriodendrella were especially abundant on sucker growth of sweetbay or swamp magnolia in Sussex County late in July and larvae and pupae of P. liquidambarisella were abundant in the southern portion of the county in mid-August, especially on new growth of sweetgum trees. Infestations of P. populiella were generally higher in MONTANA than for the past 1-2 years. Severe infestations of Proleucoptera albella occurred in Montana east of the Rocky Mountains, but caused only light damage to narrow leaf cottonwoods in the Sevier-Piute County area of UTAH. Paraleucoptera heinrichi caused severe leaf damage to Prunus lyoni in Alameda County, CALIFORNIA. VARIABLE OAK LEAF CATERPILLAR (Heterocampa manteo) caused extensive defoliation of red, white, black and post oaks on several hundred acres in Pushmataha County during early fall, which is the first outbreak of this pest to be reported in OKLAHOMA in several years. WALNUT CATERPILLAR (Datana integerrima) defoliated walnut trees in northern INDIANA in late August and was widespread in ILLINOIS, completely defoliating the same host in many areas of that State. YELLOW-NECKED CATERPILLAR (D. ministra) populations were light throughout the northern half of Illinois during the 1960 season. A heavy infestation of POPLAR TENT MAKER (Ichthyura inclusa) occurred on willows in one area of Sussex County, DELAWARE, during mid-June. SOLITARY OAK LEAF MINER (Cameraria hamadryadella) occurred in very light, local infestations in RHODE ISLAND during 1960, being virtually absent in many areas that were heavily infested during 1959. Although this pest was very destructive in CONNECTICUT in 1958 and 1959, it was practically nonexistent during 1960. BOXELDER LEAF ROLLER (Gracilaria negundella) developed heavy infestations and caused severe damage to boxelder in Elko County, NEVADA, during the 1960 season, and another GRACILARIID (Gracilaria sp.) rolled leaves of sugar maples in INDIANA. Heavy infestations of FRUIT-TREE LEAF ROLLER (Archips argyrospilus) occurred on oaks in the San Gabriel Valley in Los Angeles County, CALIFORNIA. A LEAF ROLLER (Archips ne dana) caused local damage in UTAH, and another LEAF ROLLER (Acleris chalybeana) was present in Turkey Run State Park in INDIANA during the 1960 season. GYPSY MOTH (Porthetria dispar) was somewhat more abundant in localized areas of NEW HAMPSHIRE during 1960 than it was in 1959. Larvae of WHITE-MARKED TUSSOCK MOTH (Hemerocampa leucostigma) infested sycamore trees in Kent County, DELAWARE, in early July, and in late August were common on sycamore in one area of southern Sussex County, causing light injury. CARPENTERWORM (Prionoxystus robiniae) severely damaged shelterbelts in eastern MONTANA, along with other borers, and an undetermined CARPENTERWORM bored into understocks and scions of budded and grafted locusts in KANSAS. DOGWOOD BORER (Thamnosphecia scitula) occurred in numerous areas of CONNECTICUT during the past season and infested grafted dog- wood plantings in several nurseries in the Portland area of OREGON in January. Extensive surveys delimited the premises infested and all stock originating out-of-State. All infested stock was destroyed or fumigated. The first fall record of a MAPLE CALLUS BORER (Sylvora acerni buscki) for FLORIDA was collected on silver maple at Gainesville, Alachua County, on September 15. Four adults were collected on that date and there was considerable damage apparent to trunk and larger branches of planted silver maples on the campus of the University of Florida. —lOOos = A lone infestation of EUROPEAN PINE SHOOT MOTH (Rhyacionia buoliana) was dis- covered in OREGON in a Portland nursery on September 6. The infestation and all host plants in the area were destroyed. Larvae entered buds in Manitowoc County, WISCONSIN, by May 13, and emergence had begun in Door County by July 13. Incidence of the pest increased both in population and nursery infestation during 1960 over those of 1959. European pine shoot moth did some damage to Christmas tree plantings in MICHIGAN, damaged many pines in CONNECTICUT, and pupae were present in red pine tips in RHODE ISLAND on June 3 in Warwick, Kent County. NANTUCKET PINE TIP MOTH (R. frustrana) infested Scotch pine in KANSAS, and another PINE TIP MOTH (Rhyacionia Sp.) waS common on young stands of pine in several VIRGINIA localities during 1960. ZIMMERMAN PINE MOTH (Dioryctria zimmermani) caused some damage to Christmas tree plantings in MICHIGAN. Maple and sycamore trees were damaged by AMERICAN PLUM BORER (Euzophera semifuneralis) in a few locations over CALIFORNIA, and another PHYCITID (Canarsia sp.) was abundant on sycamores in many areas of ILLINOIS. MOURNING-CLOAK BUTTERFLY (Nymphalis antiopa) severely damaged Chinese elms in San Benito County, CALIFORNIA, and another NYMPHALID (Asterocampa celtis) caused much defoliation of hackberry in KANSAS during the 1960 season. Although several other lepidopterous species were reported as causing damage during 1960 in several of the states, ORANGE-STRIPED OAKWORM (Anisota senatoria) was not observed in areas of RHODE ISLAND previously heavily infested, the absence of the pest being unexplained. Larvae of CATALPA SPHINX (Ceratomia catalpae) were first noted in DELAWARE on catalpa trees in northern New Castle County in late June, and had caused considerable injury by early July. As in 1959, several catalpa trees in eastern Kent County were completely defoliated by early August, but infestations were localized as in previous years. The pest defoliated catalpa trees in north central counties of INDIANA in August and September and was very abundant, defoliating catalpas in all areas of ILLINOIS. However, parasites were also very abundant in Illinois and killed larvae by the thousands before they matured. An undetermined PSYCHID also was abundant on evergreens and sycamores in many areas of Illinois. PUSS CATER- PILLAR (Megalopyge opercularis) was a serious pest of shade trees and a hazard to inhabitants of several communities in south central and southeastern OKLAHOMA during late summer and fall, several people being hospitalized as a result of direct contact with this venomous pest. Heaviest infestations occurred in Love, Carter, Johnson, Bryan, Coal, Pittsburg, Choctaw and McCurtain Counties, with limited infestations in a few other areas of the State during the same period. CALIFORNIA OAKWORM (Phryganidia californica) was abundant in many locations of CALIFORNIA during 1960, with considerable defoliation of native oaks, and unusually early broods of larvae occurred in the north coastal area of the State. Heavy larval infestations of a SHIELD BEARER (Coptodisca sp.) damaged foliage of poplars in central and southwest ARIZONA during June, July and August. Infestations of undetermined LEAF MINERS occurred on poplars and cottonwoods in scattered communities in UTAH and were especially numerous on hardwoods in the southern half of NEW HAMPSHIRE during the 1960 season. Of the Coleoptera reported as damaging various shade trees during 1960, ELM LEAF BEETLE (Galerucella xanthomelaena) appears to have been the most destruc- tive and most widespread. The pest was reported for the first time from IOWA, at Council Bluffs and Glenwood, and was recorded for the first time in Humboldt County, NEVADA. Elm leaf beetle was a major pest of Siberian elms in OKLAHOMA for the third successive year. Infestations continued to spread during these past few years, and by the fall of 1960 could be found throughout the State except in the panhandle area. Elms in many communities of Oklahoma were extensively defoliated, to such an extent in some instances that skeletonized leaves remaining on trees hardly cast shadows. However, in many other communi- ties only elms in certain sections of the city were infested, while remaining areas were relatively free of this pest. Elm leaf beetle migrated into southern KANSAS and, in some instances, into the east central portion of the State. - 1006 - Adults were present and laying eggs in southern ILLINOIS the week of May 15. By the week of June 26 much defoliation of elms had occurred and new adults were beginning to emerge as far north as Springfield. Elm leaf beetle was exceedingly abundant on Chinese elms in central INDIANA during 1960, with nearly every tree brown by late July. Elm leaf beetle infestations and injury were equal to, or slightly above normal level during midseason in MAINE, heavy populations developing by late July and causing severe injury to elms in Kennebec, Cumberland and York Counties. The pest was generally prevalent and as troublesome as usual in NEW HAMPSHIRE and adult activity was general in RHODE ISLAND by June 1. The pest was notice- ably destructive in PENNSYLVANIA. In DELAWARE, eggs were fairly abundant on elms in eastern Sussex County in mid-May and in northern New Castle County in early June. However, injury was less severe during 1960 than in 1959. The pest was numerous in VIRGINIA and caused considerable defoliation in TENNESSEE during the season. In ARIZONA, heavy Populations of elm leaf beetle defoliated elms in the St. Johns area of Apache County and in some areas of Maricopa County during July and August. This chrysomelid was less destructive to elm foliage in 1960 than during 1958 in several UTAH communities, except in areas of Salt Lake County, where damage was severe. Adults became active early in April in NEVADA due to warm weather, but no eggs were laid until the normal mid-May period. Damage to untreated and improperly treated trees was severe, with the beetle being found as far south as Hawthorne, Mineral County. The pest was very damaging to elms in CALIFORNIA where no control was applied. In a few locations, control was not effective and required repeat applications. Adults appeared in the Salem area of OREGON on April 28 and larvae were reported as abundant on elm at Eagle Pass on May 28. Moderate to heavy damage occurred over the entire State during the 1960 season. Distribution of Elm Leaf Beetle - 1960 — OOM a Several other LEAF BEETLES were also damaging during 1960. LOCUST LEAF MINER (Xenochalepus dorsalis) caused considerable defoliation in TENNESSEE and was responsible for brown foliage on black locust trees in southern INDIANA. How- ever, infestations failed to develop in RHODE ISLAND. Adults and eggs of IMPORTED WILLOW LEAF BEETLE (Plagiodera versicolora) were very abundant on willows in one area of Sussex County, DELAWARE, during late April, and adults were present on willow and mimosa throughout May and June in Kent and Sussex Counties, causing light injury. Unspecified WILLOW LEAF BEETLES occurred in all areas of CONNECTICUT during 1960. LARGER ELM LEAF BEETLE (Monocesta coryli) increased in intensity and in area of infestation for the second year in NORTH CAROLINA, with infestations reported from 5 counties in the southern Piedmont. Another LEAF BEETLE (Altica carinata) was observed for the first time in IOWA defoliating elm trees in one locality in Sioux City. Adults were collected during December hibernating under debris. ELM CALLIGRAPHA (Calligrapha scalaris) damaged foliage on American elms in south central, central and north central OKLAHOMA during late spring and summer, infesta- tions being somewhat heavier than those noted during 1959, especially in the north central area. The species was also present in southern, east central and locally in northern KANSAS, Also in Kansas, Chrysomela scripta complex defoli- ated many cottonwoods in southwest area, and Anomoea laticlavia stripped many honeylocusts and fed on other deciduous trees and shrubs. Because of this latter species, many nurserymen in eastern Kansas are no longer growing honey- locust. SMALLER EUROPEAN ELM BARK BEETLE (Scolytus multistriatus) was collected for the first time in OREGON during 1960 at Klamath Falls, Klamath County, on October 10. Subsequent limited surveys indicate the beetle has been in the suburban area for at least 2 years; however, no Dutch elm disease was discovered. The pest was also reported for the first time from TEXAS during 1960, specimens determined by W. H. Anderson having been collected in El Paso, El Paso County, on April 20, 1959. A new county record was Washoe County, NEVADA.

On the other hand, warmer than normal conditions are expected to prevail over much of the East except for near normal in the Northeast. This temperature pattern breeds frequent storms which are expected to produce precipitation in excess of normal over most of the Nation, except the southeast and Pacific North- west where subnormal amounts are indicated. Over the West, the Northern Plains and the Western Great Lakes, a considerable portion of the precipitation is expected to occur as snow. Weather forecast given here is based on the official 30-day "Resume and Outlook", published twice a month by the Weather Bureau.

WEATHER OF THE WEEK ENDING NOVEMBER 6 The week was unusually cold in the West and extremely warm in the East. Average temperatures for the week ranged from 18° above normal at Charlotte, North Carolina, to 15° below at Sheridan, Wyoming. In most of the Far West, tempera- tures were below normal all week. Weekly minima were below the zero level at many higher stations in the Rockies, and light frost was observed at many low-altitude stations in the northern two-thirds of California. Weekly averages generally ranged from 9° to 12° below normal in the Rockies and 6° to 9° elsewhere from the western portions of the Great Plains to the Cascade and Sierra Nevada Mountains. In the midcontinent area, the first part of the week was unseasonably warm. On November 1, maximum temperatures ranged from 90° at Laredo, Texas, to 67° at Bismarck, North Dakota. Cold air from the west moved into the Great Plains on November 2 and 3 and reached the Appalachians by the end of the period. This first wintry blast of the season produced a 24-hour temperature drop of 50° in the northern Great Plains on the Ist and 2d of November. The first general freeze of the season in the Panhandle and High Plains of Texas on the 3d followed in the wake of the season's first "norther" in that State. The entire week was warm east of the Appalachians, and the first 4 days of the week between the Appalachians and the Mississippi River. Maxima in the 80's in the Ohio Valley and Middle Atlantic States on the 2d and 3d set new records for the dates and for so late in the season at a number of stations. Precipitation generally was moderate to heavy in the midcontinent region and light in the Far West and along the east coast. Generous rainfall was very beneficial in Texas and the lower Ohio Valley. In an area including the Carolinas, Georgia, Florida, and southeastern Alabama, rainfall was much below normal, and soil moisture continued short. Much of the precipitation in the Far West fell in the form of snow. Unusually heavy amounts fell in the central Rockies where a 44-inch fall during the last 3 days of October set an early season record at Salida, Colorado. Considerable snow also fell in the Cascade Mountains, and depths above 4,000 feet in the northern Cascades now range from 1 to 2 feet. In Arizona's White Mountains, more than a foot of snow accumulated during the week. (Summary supplied by U. S.

Extracts from the bark of Acacia decurrens and Awae mollis are used in tanning. Whole wattle plantations may be completely defoli- ated. The true economic loss resulting from damage caused by the bagworm is not known with certainty, but there is a serious check to growth which, if repeated, will permanently damage the tree. There is also a substantial loss of both bark and wood increment. A secondary effect is that the increased penetration of light into the plantation, consequent upon the loss of foliage, allows strong growth of weeds. Where a mature plantation is heavily attacked, stripping may become difficult or impossible as the season progresses. The wattle industry contributes considerable income annually to South Africa; the annual value of wattle exports reached nearly 21.5 million dollars by 1953. The annual loss has been estimated to be approximately 3 percent, which would mean that if the export trade was taken as a basis the loss to the wattle-growing community of South Africa would have been about $645,000 in 1953. Losses to individual plantation owners may sometimes be quite severe during outbreak years; a bark loss of 30 percent has been recorded. Peak infestations seem to occur every 5-7 years. The endemic stage is followed by 2 years of a preparatory stage when the bagworms become more numerous, and then by a prodromal or premonitory stage of about 2 years when bagworm popula- tions increase rapidly and damage becomes evident. The eruptive stage, which follows, may last 1-3 years. Trees become completely defoliated, and bagworms may die from lack of food and are also prone to disease. An abatement of the infestation follows and populations return to normal. Assessing the degrees of infestation is best done during February, when the bag- worms are full grown and can be easily seen and when damage to foliage has reached its height. The standard system of classification of the degrees of infestation follows: (LIGHT) 1. Very few bagworms on occasional trees throughout plantations. 2. Few bagworms on most trees; no observable damage. 3. Bagworms on nearly all trees; slight damage to crowns of some trees. (MODERATE) 4. Bagworms on all trees; crowns of all trees damaged, but none completely defoliated. 5. Bagworms on all trees; some trees completely defoliated. (HEAVY) 6. Almost complete defoliation throughout plantation; occasional trees showing green foliage. 7. Virtually complete defoliation. The number of empty male bags in one partic-— ular season gives some indication of the severity of the infestation which may be expected that season. The proportion of females to males which reach maturity and are able to reproduce is approximately one to two. Therefore, by making an estimate of the number of male bags and dividing by two, a rough estimate of the number of females, expected number of larvae and degree of infestation can be made, Distribution: South Africa. Hosts: Several species of Acacia of which Acacia decurrens mollis is the most important. Life History and Habits: The species takes 12 months to complete its development. Males emerge and copulation begins at the end of July and continues through August. Adult females, which never leave their bags, reach sexual maturity around the end of July and during August, and after mating lay up to 2,000 eggs or more each. The exact number of eggs depends on the vigor of the particular female. Females lay a greater number of eggs when food is abundant during their larval development. (Psychidae, Lepidoptera) No. 138 of Series - 1040 - Hatching begins 8-10 weeks later and young larvae leave the maternal bag and start spreading in search of food. The main brood of larvae emerges during September and the adults begin dying off. Larvae encase themselves soon after hatching and feed for the better part of 6 months. At first they congregate mainly on the tops of trees and at the ends of branches with young foliage. Larval feeding damage begins to appear in October and reaches a peak in January when the larvae near maturity. Feeding generally ceases in March, at which time larvae tend to congregate. It is not unusual to find several bags attached to the same twig or grouped in bunches. Pupation begins for the males in April and in May for the females. Description: Superficially,Kotochalia juncdi more closely resembles the North American bagworm (Thyridopteryx ephemeraeformis) than does any other foreign species. (See photograph below). The males of the two species may be separated in a number of ways, the most obvious being the difference in color. K. junodi is dark brown, while T. ephemeraeformis is black. Briefly, K. jumodi is described as follows: ADULT MALE - Wing expanse about 3 mm. and length of body 1.2 mm. or less. Body clothed with dense, velvet-like, brown pile. Wings practically with- out scales; few present along basal margin. BAGS - Male bag is smaller and more slender than that of female, and after the emergence of the adult male it can be clearly distinguished by the empty pupal case protruding from the end. LARVAE - Bodies black, or almost so, and soft and fleshy except for thoracic segments which, like the head, are sclerotized and have tortoise-shell markings. PUPAE - Males and females strikingly different. Male pupa rather typical, while female shows little resemblance to a lepidopterous pupa.

In the Far West, abnormally cold weather at the beginning of the period was followed by rising temperatures until cold weather again overspread the area following the passage of a cold front during the weekend. The week was colder than normal, generally by 3° to 6° in that area. Light frost extended over agricultural areas of central and northern California, and frost ended the growing season for most crops in virtually all of New Mexico. An extreme low of -23° was recorded at Bondurant, Wyoming. The first half of the week was abnormally cold and the second half warm in the midcontinent area. Temperatures ranged from near zero to 75° in North Dakota. Freezing extended almost to the Gulf coast in the Mississippi Valley. A low of 24° in northeastern Louisiana on the 10th was a month earlier than usual for a temperature that low there. Along most of the east coast, temperatures were relatively warm at the beginning and end of the period and cold the remainder of the week. In much of the North- east, however, this was the coldest week of the season to date. Freezing for the first time this season covered all parts of New England, much of Georgia, and the northwestern interior sections of -Florida. Most of the week's significant precipitation fell along the north Pacific coast, in the central and lower Rockies, along the Gulf coast, and in the Northeast. In the Southeast, where the dry spell is one of the most persistent on record in a number of areas, rainfall was extremely light in Georgia and the Carolinas. Florida, however, received general beneficial showers early in the week. Amounts were variable, but, generally ranged up to 1 or 2 inches in the southern portion and eastern half of the Peninsula and under 0.50 inch elsewhere. Soil moisture was improved and is now adequate on the east coast of Florida. A storm in the Southwest early in the period brought precipitation to much of Arizona and New Mexico, but missed southern California where damaging fires occurred last week. Some precipitation fell at Blythe, California, last week, the first rain there in 4 months. Snow fell in the mountainous and northern sections of the country. Depths are now 2 to 3 feet in the northern Cascades at elevations above 4,000 feet. Snow in the western Great Plains ranged up to 3 inches at Goodland, Kansas. Parts of Ohio and middle and northern portions of Pennsylvania reported their first snow- fall of the season. In the snow belt immediately east of Lakes Erie and Ontario in western New York State, snowfall ranged up to 9 inches. (Summary supplied by U. S. Weather Bureau). - 1043 - CEREAL AND FORAGE INSECTS SOUTHWESTERN CORN BORER (Zeadiatraea grandiosella) - NEW MEXICO - Larvae much less abundant in roots of corn in Bernalillo and Sandoval Counties than in eastern and southern counties.

A LEAFHOPPER (Protalebrellia brasiliensis) - Single specimen collected in light trap at Public Health Service Quarantine Station in Honolulu on July 17, 1961, in addition to specimen collected in same light trap on September 13, 1960. These single records in the harbor area indicate that the species is still doubtfully established in Hawaii. (Joyce). A REDUVIID (Polididus armatissimus) - A specimen taken in Aina Haina, Oahu, on July 20, 1961, resting on side of a house, and another specimen taken in a light trap at Kailua, Oahu, on September 11, 1961, appear to be a new island record for this species. (Joyce). A SCIOMYZID FLY (Sepedon praemiosa) - Release of this predator of the liverfluke snail (Lymnaea ollula) was approved by the board members of the Department of Agriculture at their September meeting. Like S. macropus from Nicaragua, and which is now well established in the Islands, S. praemiosa is strictly an aquatic species, the larvae feeding on snails which are in the water. The original breed- ing stock of S. praemiosa was collected in Los Angeles County, California,by Dr. Clifford 0. Berg of Cornell University. (Mabel Chong). A THRIPS (Aleurodothrips fasciapennis) - This predaceous species was found effec-— tively preying upon heavy infestations of PINEAPPLE SCALE (Diaspis bromeliae) on pineapple plants in Waialua, Oahu. Several collections have been recorded from pineapple and other plants, but this is first observation of the thrips preying upon the scale. The new island records are from Hawaii at Hilo in 1951 by Cc. J. Davis and from Lanai in 1955 by K. Sakimura. The presence of the scale in the native forest at high elevations was observed at 2,500 feet on Kanehoa, Oahu, and at 3,400 feet on Lanaihale, Lanai. (Sakimura). MOTH FLIES - A new island record for two species of Psychodidae resulted from recent collecting by Prof. T. C. Maa on Kauai. Psychoda quadrifilis and P. uncinula were taken in the dry cave of Haena Caves on August 7, 1961, and P. uncinula was taken at Kokee Park on August 6, 1961. Det. by L. W. Quate. (Lofgren). RUSTY PLUM APHID (Hysteroneura setariae) - Numerous specimens collected on wire- grass (Eleusine indica) at Ewa, Oahu, several times during September. Species appears to be a recently established immigrant as it has not previously been reported in Hawaii. Determination was confirmed by L. M. Russell. H. setariae has recently been shown to act as a vector of sugarcane mosaic in Louisiana; this disease, along with its other known vector, CORN LEAF APHID (Rhopalosiphum maidis), occurs in Hawaii.

Above normal temperatures are predicted for the Atlantic Coast States and extreme Northern Plains. In unspecified areas, near normal averages are indicated. This temperature pattern favors considerable storminess and heavy precipitation in most of the eastern half of the Nation and also the Southern Plains. Much of this precipitation should occur as snow in a broad band from the Southwest to the Great Lakes. Light precipitation is in prospect for the Far West and extreme Northern Plains. Weather forecast given here is based on the official 30-day "'Resume and Outlook", published twice a month by the Weather Bureau.

WEATHER OF THE WEEK ENDING NOVEMBER 20 Unseasonably mild weather prevailing across the Nation at the beginning of the period ended after one or two days in the Far West,about midweek in the mid- continent area and on Friday in the East. Temperatures for the week averaged as much as 15° below normal in the southwestern Great Plains and central Rockies and well below normal in all areas west of the Continental Divide. Subzero minima occurred at most higher elevations in the Rocky Mountain region, with lows of -22° in Wyoming and -27° in Colorado. Temper- atures fell almost to zero in the Great Basin area and frost caused slight damage to vegetable crops in some interior valleys of California late in the week. The week was warmer than normal in the northern Great Plains, about normal in the Mississippi Valley, and unusually warm in the southeast area where weekly averages were as much as 9° above normal. Precipitation fell over the east and south central areas the first two days of the period, the midcontinent areas on Wednesday and over the northeastern quarter on Thursday. A weak storm system over southern California on the 16th moved across the Nation producing a band of precipitation from northern Nevada to the Middle Atlantic Coastal States. Total precipitation for the week was very light from the extreme upper Mississippi Valley and northern Great Plains to the Cascade Mountains. Amounts exceeded 0.50 inch at many points in the central and lower Rocky Mountain area and east of a line joining Escanaba, Michigan, to El Paso, Texas, except that amounts were very light in Florida and South Atlantic Coastal areas. More rain is still needed badly in Florida, central and southern Georgia and parts of the Carolinas. Moderate to heavy precipitation fell in California and Nevada as the period ended.

The losses presented in that volume began on page 841 and were completed on page 960. A total of 17 cooper- ating states submitted losses for 1959. Figures for 1960 were submitted by 18 states. Losses for 1960 from California, Florida and Minnesota were published in CEIR 11(38); those from Colorado, Utah, Wisconsin and Wyoming in CEIR 11(40) ; and cotton insect losses from Arizona in CEIR 11(41). Insect losses for the States of Arkansas, Georgia, Idaho, Illinois, Kansas, Maryland, Nebraska, New Mexico, Oklahoma and Texas are presented in this issue of the Report, utilizing the form approved by the Entomological Society of America's Committee on Insect Survey and Losses. The acceptance of this standard form is being emphasized and it was used by the majority of the states that submitted loss information for 1959 and 1960. Special Instructions for Use of the Loss Table: 1. Under the "Pest or Pest Complex" columns, abbreviations of pests are used. A legend of the pest or pests can be found at the end of table. 2. The numerical figures in several of the columns have been reduced to thousands, the letter "M" being used when applicable. 3. The loss estimates for Texas were submitted on a district basis in most cases in 1960. As an aid to the reader, a map showing Crop Reporting Districts in Texas, is reproduced on the following page.

FORO A ORK AK OK AK Reports in this issue are for week ending November 24 unless otherwise indicated. - 1084 - WEATHER OF THE WEEK ENDING NOVEMBER 27 The past week's weather was generally stormy, with widespread precipitation that occurred as heavy snow in the Pacific Northwest and as mostly heavy rain in much of the eastern third of the Nation. The week was abnormally cold in the Pacific and south Atlantic Coastal States and unseasonably mild elsewhere. The entire week was cool in the Pacific States, where average temperatures for the week were 9° below normal in northern Washington and the Sierra Nevada Mountains and generally 3° to 6° below elsewhere. Freezing occurred in northern and central portions of California. From the Rocky Mountain States to the Atlantic coast, the week was abnormally cold at the beginning, followed by rising temperatures the remainder of the period. In north-central areas, maximum temper- atures rose into the 50's and 60's the latter part of the week. Detroit,Michigan, reported 58° on the 26th. A storm off the north Atlantic coast on Monday and Tuesday produced the most general snowfall of the season to date in the Northeast. In New England, total snowfall for the storm ranged from 4 to 10 inches, except near 1 inch along the coast where the snow turned to rain, 1 to 4 inches in northwestern Vermont, and over 10 inches from east-central New Hampshire to coastal Maine. At Greenville, Maine, 25.0 inches of snow in 24 hours on the 21st set a new record for any month and greatly exceeded the previous November record of 16.0 inches in 1943. At Rockland, Maine, 4.24 inches of precipitation in 24 hours on the 20th and 21st set a new November record. The storm that produced the most extensive precipitation, as well as the heaviest in many areas, moved from California at the beginning of the week to the Atlantic coast on Thursday. Heavy amounts fell from the Mississippi Valley to the Appala-— chians on Tuesday, Wednesday and Thursday, and’ east of the Appalachians on Thursday, Friday and Saturday. Total falls during this storm generally exceeded an inch from the central and lower Mississippi Valley to the Atlantic coast. These heavy rains further replenished soil moisture in the lower Ohio Valley and South- east. Amounts ranged from 1 to 2 inches in Georgia and North Carolina and gener- ally exceeded an inch in South Carolina. More rain is still needed in parts of Georgia and the Carolinas to fully replenish subsoil moisture. In Florida, totals generally ranged from about 0.30 to 0.75 inch, enough to only slightly improve soil moisture. Storms at the beginning and end of the week produced moderate to heavy precipita- tion over most of California and light to moderate rain and snow in the central and lower Rockies. In the Pacific Northwest, precipitation occurred almost daily. Heavy snows fell in the mountains of Oregon and Washington, and even at lower elevations in Washington and western Oregon. In Washington, heaviest snowfall occurred on the eastern slopes of the Cascades where Chelan measured 13 inches and Leavenworth 24. At the end of the week, 1 to 2 inches of snow covered the ground in the central basin of Washington, 3 to 8 inches in the eastern portion of the State, and 6 to 10 inches in the northern valleys. In Oregon, heavy snow from Eugene to Medford and in the Klamath Falls area closed many highways, damaged power and communication lines, and isolated some communities. Flooding also occurred along Oregon's coastal streams where total precipitation for the week ranged up to 9.70 inches. (Summary supplied by U.S. Weather Bureau). - 1085 - CEREAL AND FORAGE INSECTS GREENBUG (Toxoptera graminum) - OKLAHOMA - Light, 15 per linear foot, in wheat in Jefferson County. (Okla. Coop. Sur.). ARKANSAS - None found in small grains in Washington County. (Ark. Ins. Sur.). CORN LEAF APHID (Rhopalosiphum maidis) - OKLAHOMA - Light, 8 per linear foot, on wheat in south central area. (Okla. Coop. Sur.). APPLE GRAIN APHID (Rhopalosiphum fitchii) - OKLAHOMA - Light, 5 per linear foot, on wheat in Jefferson County. (Okla. Coop. Sur.). ENGLISH GRAIN APHID (Macrosiphum granarium) - ARKANSAS - Numbers low, 1-2 per linear foot, in northwest area. (Ark. Ins. Sur.). CHINCH BUG (Blissus leucopterus) - KANSAS - Annual survey conducted in 58 counties in northeast, east central, southeast, north central and south central districts during early November; 2 stops made in each county. Average counts were non- economic (0-250 bugs per square foot of bunch grass) in all counties, except in Montgomery County (southeast) where counts were light (500 per square foot). (Bell, Gates, Hohnholt, Peters). OKLAHOMA - Results of 1961 survey indicate populations declined or remained the same in all but one county surveyed. Okfuskee County showed increase to moderate (500-1,000 bugs per square foot of bunch grass) which was highest county rating included in survey. Lincoln, Rogers and Tulsa Counties were light (250-500 per square foot), with remaining counties non- economic (0-250 per square foot). This is fourth consecutive year that overall ratings have declined. (Okla. Coop. Sur.). GRASSHOPPERS - MINNESOTA - Limited checks on egg development made during period November 13-20, with only eggs of Melanoplus bivittatus found; majority in coagu- lated stage, with few in early eye-spot stage. On sheltered ditch bank, few segmented eggs observed. Fall weather has been warmer than usual, allowing some egg development before winter. (Minn. Ins. Rpt., Nov. 20). SPOTTED ALFALFA APHID (Therioaphis maculata) - SOUTH DAKOTA - Egg-laying forms found for first time in State November 20 in alfalfa near Missouri River in Charles Mix and Gregory Counties. (Walstrom). ARKANSAS - Counts very low in Washington County; only occasional specimen taken in sweeping several fields. (Ark. Ins. Sur.). ARIZONA - Infestations generally low in alfalfa, statewide. (Ariz.Coop.Sur.). PEA APHID (Macrosiphum pisi) - ARKANSAS - Averaged 30-40 per 10 sweeps of 15-inch net in Washington County vetch. (Ark. Ins. Sur.). TARNISHED PLANT BUG (Lygus lineolaris) - ARKANSAS - Continues active in legumes in northwest; counts 1-4 per 10 sweeps of 15-inch net. Occasional nymph taken in sweep net on November 20. (Ark. Ins. Sur.). A LEAFHOPPER (Fieberiella florii) - OREGON - Collected on quince in Corvallis, Benton County, during August. This species is known to transmit both western X and aster yellows viruses. This collection west of the Cascade Mountains is a new record for the State. (Swenson, Nov. 18). SOYBEAN CYST NEMATODE (Heterodera glycines) - TENNESSEE - Infestation found in second field in Carroll County, approximately one-half mile from original find. (PPC, So. Reg., Oct. Rpt.). ILLINOIS - Second infested property in Pulaski County confirmed during October. Property immediately adjacent to first find in county. (PPC, Cent. Reg.).

(Tarpley). = OST — Some Highlights of Insect and Mite Occurrences in Canada 1961 Prepared by C. Graham MacNay In British Columbia, GRASSHOPPER populations continued to be relatively small, although increases were evident in some areas. In much of the agricultural area of the Prairie Provinces, a continuation of the impressive increase of recent years was recorded, and damage was aggravated by extremely dry, hot weather. In Alberta, the area infested (19,000 square miles) was about 80 percent greater than in 1960, the most severe infestations occurring in the southwestern part of the Province. In the prairie area of Saskatchewan, the outbreak in field crops, pastures and gardens was the most severe in 20 years; crop damage was mainly Marginal but extended throughout many fields. In Manitoba, the total area of infestation (9,000 square miles) was more than double that of 1960, the area of severe infestation being more than 3 times as great, and the area of moderate infestation more than 4 times as great as in 1960. In British Columbia, RED-BACKED CUTWORM (Euxoa ochrogaster) was at a low ebb and GLASSY CUTWORM (Crymodes devastator) again caused some damage to pasture in the Dawson Creek area. In Alberta, ARMY CUTWORM (Chorizagrotis auxiliaris) was injur- ious to winter wheat for the second successive year in the Bow Island, Milk River, Warner and Vulcan districts, and the infestation extended into southwestern Saskatchewan. RED-BACKED CUTWORM severely damaged garden and irrigated crops in southern Alberta and attacked grain in the central part of the Province, but crop losses were much lighter than in 1960. There was a marked increase in infesta- tion and damage by PALE WESTERN CUTWORM (Agrotis orthogonia) in the southern part of the Province and a further increase is expected in 1962. In southern and western areas of Saskatchewan, this cutworm severely damaged thousands of acres of cereals and flax in the most severe and widespread infestation in many years. In Manitoba, CUTWORMS continued to be very injurious in gardens and RED-BACKED CUTWORM was numerous in cereal and sugar beet crops. In Ontario, CUTWORM damage increased, especially in tobacco-growing areas. In the Saguenay-Lac St. Jean area of Quebec, CUTWORMS were numerous in truck gardens. In New Brunswick, ARMYWORM (Pseudaletia unipuncta) was injurious to hay in widely-separated areas from Fredericton southward and much cutworm damage occurred in gardens. In Nova Scotia, a moderate infestation of BRONZED CUTWORM (Nephelodes emmedonia) was present in grassland at Cow Bay. In southwestern Ontario, WIREWORMS were more injurious than during the previous 5 years, damaging tobacco, corn, potatoes and grain, and Oestodes tenuicollis occurred in oats in Oxford County. In Kent County, Nova Scotia, counts in sod revealed 12 or more wireworms per square foot. In Quebec, WHITE GRUBS damaged grassland, lawos and gardens in the Eastern Townships. In Ontario, SLUGS were very injurious in both field and garden. In Saskatchewan, FALSE CHINCH BUG (Nysius ericae) damaged crested wheatgrass, wheat and flax at Vanscoy, Dunblane, Milden and Saskatoon, the first record of severe damage by this insect in the Province. In the Milk River Valley, Alberta, where ALFALFA WEEVIL (Hypera postica) was first found, the number of larvae per net sweep averaged 483, compared with 263 in 1960, and in the Lethbridge area, damage was noticeable for the first time. At Taber, a SUGAR-BEET NEMATODE appeared for the first time in Western Canada. In Manitoba, a new species of SPIDER MITE (Tetranychus n. sp.) heavily infested barley in the south central area of the Province, and light infestations occurred in rye, corn and wheat near Winnipeg. Damage resembled that of net blotch. Large flights of BEET WEBWORM (Loxostege sticticalis) occurred late in Jume. FLEA BEETLES were very injurious to seedling rape. In Ontario, ROOT MAGGOT infestations in tobacco ~= 1092 - were severe for the fourth consecutive year. Hylemya liturata was the principal species, indicating a change in the species complex. Early turnips were damaged by CABBAGE MAGGOT (H. brassicae). In corn-growing areas, NORTHERN CORN ROOTWORM (Diabrotica lon icornis) continued to increase markedly. In Prince Edward Island, BARLEY JOINTWORM (Harmolita hordei) was more widespread and numerous than in 1960. In British Columbia, a pest resembling corn earworm on corn, insecticide-resistant strains of CARROT RUST FLY (Psila rosae) and CABBAGE MAGGOT, and increased numbers of GARDEN SYMPHYLAN (Scutigerella immaculata) were injurious. In Saskatchewan, FLEA BEETLES on crucifers and COLORADO POTATO BEETLE (Leptinotarsa decemlineata) were unusually numerous. In Manitoba, SIX-SPOTTED LEAFHOPPER (Macrosteles fascifrons) caused much "yellows" in lettuce, and resistant strains of ONION MAGGOT (Hylemya antiqua) were injurious in market gardens. In Ontario, SLUGS headed the list of pests. An outbreak of H. liturata severely damaged seeds and tubers in Norfolk County; resistant ONION MAGGOTS were injurious; peppers were severely attacked by PEPPER MAGGOT (Zonosemata electa) and EUROPEAN CORN BORER (Ostrinia nubilalis), but the latter insect was generally less numerous on corn. In Quebec, CABBAGE MAGGOT in Montreal market gardens, SPINACH LEAF MINER (Pegomya hyoscyami) in the St. Hyacinthe and St. Hilaire areas, and ASPARAGUS BEETLES (Crioceris spp.) generally, were major pests. At Lincoln, New Brunswick, APHID populations on potatoes were the largest on record. In Nova Scotia, there was an upsurge of MELON APHID (Aphis gossypii) on cucurbits and of SPINACH LEAF MINER on Chenopodi- aceae, and GREENHOUSE SLUG (Milax gagates) was recorded for the first time at Amherst. In Prince Edward Island, COLORADO POTATO BEETLE, FLEA BEETLES and especially TARNISHED PLANT BUG (Lygus lineolaris) were very numerous on potatoes; and a WEEVIL (Trachyphloeus bifoveolatus) damaged many vegetable crops. In western Newfoundland, CABBAGE MAGGOT was a major pest of crucifers. Important occurrences on fruit included: At Saanichton, British Columbia, MEADOW SPITTLEBUG (Philaenus spumarius) on strawberry and PEAR LEAF BLISTER MITE (Erio- phyes pyri); at Vancouver, the first report of damage by a WEEVIL (Brachyrhinus singularis) ; in the Okanagan Valley, GRAPE PHYLLOXERA (Phylloxera vitifoliae) was new, CODLING MOTH (Carpocapsa pomonella) was unusually numerous, Tetranychus mcdanieli and RUST MITES on apple, pear and cherry, and LEAFHOOPERS on many hosts. In Ontario, ORIENTAL FRUIT MOTH (Grapholitha molesta) caused no economic losses, partly because of very heavy parasitism; EUROPEAN RED MITE (Panonychus ulmi) was very numerous on peach, plum and apple; EUROPEAN FRUIT LECANIUM (Lecanium corni) declined markedly as a pest of peach; CURRANT FRUIT FLY (Epochra canadensis spread southward and EASTERN TENT CATERPILLAR (Malacosoma americanum) increased in eastern Ontario. In southern Quebec, EUROPEAN RED MITE, APPLE MAGGOT (Rhagoletis pomonella) , FRUIT-TREE LEAF ROLLER (Archips argyrospilus) and EASTERN TENT CATERPILLAR increased markedly and CODLING MOTH decreased. In Nova Scotia, FALL CANKERWORM (Alsophila pometaria) and WINTER MOTH (Operophtera brumata) were numerous generally, and EUROPEAN RED MITE in some orchards. In Prince Edward Island, a TENTIFORM LEAF MINER was numerous. Among miscellaneous pests, MASKED HUNTER (Reduvius personatus) appeared as a predator of stored-product insects in coastal and interior British Columbia, ROCKY MOUNTAIN WOOD TICK (Dermacentor andersoni) was unusually numerous, CLOVER MITE (Bryobia praetiosa) was a major pest at Kamloops, British Columbia, and Edmonton, Alberta; AMERICAN DOG TICK (D. variabilis) was abundant in southern Manitoba; and an outbreak of LARDER BEETLE (Dermestes lardarius) occurred in packaged fish meal in several processing plants in Newfoundland. O93 = INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES GOUT FLY (Chlorops pumilionis (Bjerkander)) Economic Importance: This chloropid fly is one of the most serious pests of winter and spring wheat, barley and rye in Europe. When climatic conditions are favor- able, destructive outbreaks may occur. Activity of the pest is greatly reduced by cold, windy or rainy weather. The symptoms of infestation differ according to the time of year. The second-generation or winter-brood larva stunts the attacked shoot and causes an increase in the breadth of the leaves which appear unusually green. There appears to be no stem, while the central leaves are spirally curled. The first-generation or summer-brood larva causes a characteristic swelling of the stem of two or three internodes ending in the swollen head imprisoned in its sheathing leaves. It is from this latter symptom that the name gout fly is derived. Infested plants cease growth almost immediately. The reduction in grain yield has been over 50 percent in many instances and sometimes total loss of the crop has resulted from infestations of the pest. A Damage to Cereal Crop Plants by Larvae of Chlorops pumilionis (Bjerkander) A - Typical Injury by Second Generation (Winter Brood) B - Typical Injury by First Generation (Summer Brood) J ee EE EE eee ; (Chloropidae, Diptera) No. 139 of Series = ilojeyl Hosts: Wheat, barley and rye are the principal cultivated hosts and quackgrass (Agropyron repens) the most important and probably the only wild host plant. Distribution: Recorded throughout all of Europe and into Siberia in the USSR. The pest is also believed to be present in the Far East. Life History and Habits: Two generations are reported throughout most of the area of the insect's distribution; a summer and a winter brood. In the British Isles, adults emerge about the end of May and deposit eggs singly, usually on the upper side of the leaves of host plants. Normally only one egg is laid on each shoot. Eggs hatch in about 8 days. The young larva enters the center of the shoot and then feeds its way down one side of the developing head and on as far as the first internode, leaving a characteristic groove. The larva passes through 2 molts, after which it turns around with its head pointed upward and ascends a short distance before pupation. Second-brood adults emerge about 36 days later in August. Oviposition by this brood usually takes place on quackgrass, but occasionally on winter wheat or barley and on volunteer wheat and barley. Larvae overwinter head downwards in shoots of host plants and pupate after reversing their position about late February or early March. Description: ADULTS - Male: Head yellow, occiput dark, a black triangular patch about the ocelli; frons brownish-yellow; antennae black, yellow at base; lower part of face paler, eyes green and rather large.

Greatest departures are indicated for the Ohio Valley area. Below normal temper-— atures are predicted for most of the area west of the Continental Divide, with most unseasonable values in the Pacific Northwest. In the remaining unspecified area, near normal averages are in prospect. This predicted temperature pattern, it will be recalled, is more or less opposite to that of last December which was so cold in the East. Precipitation is expected to exceed normal over most of the area west of the Continental Divide and also from the Great Lakes westward. Sub- normal amounts are indicated for the southern half of the Nation eastward from the Divide. In unspecified areas, near normal amounts are indicated. Weather forecast given here is based on the official 30-day "Resume and Outlook", published twice a month by the Weather Bureau.

WEATHER OF THE WEEK ENDING DECEMBER 4 This week was unseasonably mild and dry in contrast to the stormy weather and widespread precipitation of the previous week. Temperatures for the week averaged above normal everywhere, except in Florida and the lower Atlantic coastal areas where they were slightly below. The week was mildest, relative to normal, in the northern Great Plains where temperatures averaged as much as 9° above normal. This was the second consecutive unseasonably mild week in the midcontinent area, and the second consecutive cooler than normal week in the lower Atlantic Coastal States. Precipitation exceeding an inch for the week generally was limited to portions of the Pacific States and was mostly negligible east of the Rockies. Considerable fog and occasional drizzle or snow flurries occurred in central and northern areas between the Mississippi River and the Rocky Mountains. Tempera- tures were unseasonably low in northern areas east of the Rockies the first part of the period when subzero minima were reported from points in North Dakota and Wisconsin. Cold air overspread the South on Thursday and subfreezing minima were reported as far south as Lake Charles, Louisiana; Mobile, Alabama; and Tallahassee, Florida. The weekend was unusually mild everywhere east of the Rockies, with Maxima ranging in the 70's and 80's in Florida and Texas and in the 50's and 60's in northern areas. Weekend maxima rose to near-record high levels in the upper Mississippi Valley and Great Lakes region. In the Far West, temperatures remained slightly above to well above normal all week. Precipitation in California for the week totaled 2 to 5 inches in the San Joaquin Valley and along the north coast, with even heavier amounts in the mountains, but totaled less than an inch in southeastern desert areas. This California precipi- tation brought seasonal totals to date up to 100 to 200 percent of normal. Weekly totals ranged from 1.50 to 3.00 inches along the Oregon coast, 1.00 to 1.50 inches in the inland valleys of western Oregon, and up to about 1.00 inch just east of Cascade Mountains; but only a few hundredths of an inch fell in the remainder of the State. In Washington, precipitation totaled 1.00 to 2.00 inches along the coast and over 0.50 inch in the east. Amounts generally were light elsewhere in the Far West. Large areas east of the Rocky Mountains received no precipitation at all during the week. In much of the Southeast, soil moisture remained defi- cient, and in some sections that received beneficial rains during the previous week the soil was getting dry again. Most precipitation fell in the form of snow in mountainous and northern areas. In the Far West, the mountain snowpack ranges up to nearly 4 feet in the Sierras, to 6 feet or more in the Cascades, and 2 feet at scattered points in the central and northern Rockies. In the southern Rockies, (Continued on page 1100) = 1097 = CEREAL AND FORAGE INSECTS GREENBUG (Toxoptera graminum) - OKLAHOMA - Populations general over all counties checked in eastern area.

Lower elevations are generally bare in the remainder of the Far West, although following a locally heavy weekend snowstorm in central Nevada, Austin reported an 1l-inch cover on Sunday morning. Snowcover east of the Rockies is limited to extreme northern areas and generally amounts to no more than a few inches. In northern New England, the snowcover exceeds a foot at Greenville, Maine, and Berlin, New Hampshire; most of this fell during a storm on Monday and Tuesday. (Summary supplied by U. S. Weather Bureau). Oe INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES HOP FLEA BEETLE* (Psylliodes attenuata Koch) Economic Importance: This chrysomelid is considered to be one of the most important pests of hop and hemp in Europe. Local, sporadic outbreaks on hops have been very severe in England and in areas of middle Europe, particularly when weather conditions are favorable. The adults feed on the tender leaves of hop plants, which become badly skeletonized if the adults are numerous, and growth may be severely retarded. The hop cones are also attacked; particularly on young plants and those in nursery beds. Cone damage has been regarded as the most economic, since feeding by the adults riddles them with small holes, which decreases their market value. In the USSR, damage by the adults to hemp has been placed second only to the damage caused by the European corn borer (Ostrinia nubilalis). The adults of P. attenuata skeletonize the leaves of hemp and retard development of the plants. The stems, from which fiber is obtained, are shorter by 7 to 37 percent and the loss in yield of seeds varies from 13 to 47 percent. Some larval damage also occurs. In England, several other species of flea beetles have been reputed to attack hop, but P. attenuata is the only one that caused economic damage. This beetle has often been mis- taken for Chaetocnema concinna in England. Distribution: Apparently occurs throughout most of Europe, except in the extreme northern and some southern portions, and east into Siberia in the USSR. Hosts: Hop, hemp and bigsting nettle (Urtica dioica). General Distribution of Psylliodes attenuata Koch Life History and Habits: The biology as recorded in England is as follows: Adults overwinter in various places, including old hop bins, in crevices of hop poles and under debris and soil. The adults may be found on nettles adjacent to hop gardens until the winter is far advanced. Only one generation a year occurs, the total we * Also known as hemp flea beetle (Chrysomelidae, Coleoptera) No. 140 of Series - 1102 - life cycle from egg to adult being 67-71 days. Adults first appear in May and begin feeding on nettle and hop plants. Eggs are deposited in the soil near hop hills during May and June and the resulting larvae feed on roots of various plants including hop. Adults reappear in September and start to feed in the cones. In the USSR, the biology as recorded in the northern districts of the Black Soil Zone is as follows: Adults begin to emerge at the beginning of May, being particularly abundant in July and disappearing about the middle of August. Each female may lay about 300 eggs, which are deposited in the upper layer of soil. Larvae hatch in 8-10 days and feed on small roots of hemp, pupating in the soil. The total life cycle from egg to adult is completed in 52-70 days. New adults attack leaves of hemp and hop plants, passing to these crops from bigsting nettle (Urtica dioica). Description: ADULT - Oval, coppery or greenish. Head small, with punctures; two crossed furrows present between eyes; antennae dark, lighter at base. Thorax thickly punctured. Elytra long, with regular and deep punctures. Legs reddish- brown, femora darker. Differs from Chaetocnema concinna and C. tibialis in the 10-segmented antennae and hind tibiae. (See illustration below). Length 2-3 mm. EGG - Pale yellow, oval. Length 0.5 mm. LARVA - White; head capsule, prothor- acic and anal plates light brown. Length 5-6 mm. PUPA - White. On first four abdominal segments are four setae in a cross-line and six on the remaining segments. Length 3 mm.

Temper- atures for the week averaged below normal from the western Great Plains to the Pacific coast and above normal in most of Texas and from the Mississippi Valley eastward. The week was 12° colder than normal in the northwestern Great Plains, where latter part of the week was extremely cold,and as much as 9° warmer than normal along the west gulf coast and in northern Maine where unseasonably mild weather prevailed until the last day of the period. A weekend cold wave over most of the area west of the Appalachians brought the first general subzero temperatures to the North Central Interior. On Sunday morning, Goodland, Kansas, had -10°, and Dalhart, in the Texas Panhandle, 3°. In Montana, where lows were -20° or lower, this severe cold spell was reported to be the worst in nearly 2 years. Subfreezing minima extended to the coast in Washington and Oregon, and frost occurred in the southern valleys of Arizona. Ice now covers lakes and streams in Minnesota. Precipitation fell in most areas from the Mississippi Valley eastward early in the week and over most of the Nation, except California and Florida the last 3 days. Weekly totals exceeded 2 inches in the lower Ohio and lower Mississippi Valleys and ranged up to nearly a foot in central gulf areas. From the Great Lakes eastward amounts generally ranged from 0.50 to 1.00 inch. Amounts were light in Florida and along the south Atlantic coast. Soil moisture continued short to very short in Florida and more rain is needed in southeastern Georgia. Most precipitation in the north central and western Interior areas fell in the form of snow. Weekend snows at higher elevations in New Mexico ranged up to 30 inches. In the central Great Plains, falls ranged from 2 to 7 inches over much of Nebraska, 4 to 9 inches in Kansas, 2 to 4 inches in all of Missouri, except the southeastern portion, 1 to 5 inches in South Dakota, 2 to 4 inches in the lower Ohio Valley, and a few inches in parts of the Northeast. From one to several inches of snow now covers the Rocky Mountain area as far south as northern Arizona and New Mexico, the Great Plains to western Oklahoma and northwestern Texas, and the Mississippi Valley to central portions of Missouri and Illinois. In the northern Cascade Mountains, depths now range from 40 to 80 inches. (Summary supplied by U. S. Weather Bureau). - 1105 - CEREAL AND FORAGE INSECTS GREENBUG (Toxoptera graminum) - NEW MEXICO - Infestations range from none to relatively heavy. Counts averaged from approximately 30 to over 300 per linear foot in infested fields of wheat in Curry County. (N. M. Coop. Rpt.). OKLAHOMA - Checks in Enid-Kingfisher area indicate no general outbreak has occurred; however, there is some indication that localized "spots" may exist and that close obser- vation of situation in wheat-growing areas of State should be made. Counts per linear foot, by county, were as follows: Garfield - usually less than 5, but up to 10-25 in one field; Kingfisher - 1-15, up to 50 in one field; Caddo - 0-2; Tillman - 0-6; Jackson - 3-25; Marshall - 10. Checks in some fields at Guthrie, Logan County, revealed greenbug less common now than 3 weeks previous. (Okla. Coop. Sur.). ARKANSAS - Very few found in fields checked in east and northeast areas; none present in most fields. Highest count; 12 per 50 sweeps of 15-inch net. (Ark. Ins. Sur.). KANSAS - Only species of aphid observed in the few fields of wheat and barley checked in southeastern area. Highest counts averaged 2 per foot of row; counts much less than one in majority of fields. (Peters). Occasional specimens found on wheat plants examined in Rooks County November 29. (Somsen). APPLE GRAIN APHID (Rhopalosiphum fitchii) - OKLAHOMA - Light to medium popula- tions observed on wheat, by county, as follows: Harmon, 8 per linear foot; Jackson, 18-20 per linear foot; and Marshall, up to 40 per linear foot. Occa- sional counts of less than 5 per linear foot noted on wheat checked in Enid area of Garfield County. (Okla. Coop. Sur.). CORN LEAF APHID (Rhopalosiphum maidis) - OKLAHOMA - Light populations of 5-20 per linear foot observed in Kingfisher and Garfield Counties, and 10-12 per linear foot in Tillman, Jackson and Greer Counties. (Okla. Coop. Sur.). ENGLISH GRAIN APHID (Macrosiphum granarium) - OKLAHOMA - Light populations of 3-20 per linear foot noted on wheat checked in Kingfisher and Garfield Counties. (Okla. Coop. Sur.). CHINCH BUG (Blissus leucopterus) - ILLINOIS - Samples for annual survey were collected November 13-30 and processed November 20 through December 4 by cooper- ating Federal and State agencies. Populations were the lowest for many years. Based on county averages, 2 counties rated light, one moderate, and one severe in 1961, compared with 12 light, 11 moderate and 3 severe in 1960. State average of chinch bugs per square foot for 1961 was 90.5, compared with 289.7 for 1960. There is a potential threat of damage during 1962 in an area of eastern part of State including the northern half of Champaign County and exten- ding northeastward into southern Iroquois County. Light infestations may occur from this area southward into Douglas County and westward into McLean County and also in an area extending from central Grundy County southeastward into northern Iroquois County. However, these potentials will develop only if weather condi- tions are ideal for chinch bug survival and development between now and small grain harvest in 1962. (111. Ins. Rpt.). WINTER GRAIN MITE (Penthaleus major) - KANSAS - Counts less than 5 per foot of row in one field of wheat checked in Montgomery County. (Peters).

FRUIT INSECTS OLIVE SCALE (Parlatoria oleae) - CALIFORNIA - Heavy on dwarf peach nursery stock in Yuba City, Sutter County, and medium on flowering peach in Marysville, Yuba County. (Cal. Coop. Rpt.). Citrus Insect Situation in Florida - End of November - CITRUS RUST MITE (Phyllo- coptruta Oleivora) infested 68 percent of groves (norm 72 percent); 46 percent economic (norm 49 percent). A downward trend has developed and populations will drop below normal level in most districts during December. Highest districts are Bartow, Gainesville, west coast, Brooksville, Indian River and ridge. CITRUS RED MITE (Panonychus citri) infested 38 percent of groves (norm 57 percent); 10 per- cent economic (norm 26 percent). Population is at lowest level in 10 years of record and little increase is expected. Highest district is Brooksville. TEXAS CITRUS MITE (Eutetranychus banksi) infested 30 percent of groves; 11 percent economic. Population continues in low range in all districts. Very few damaging infestations are expected. FLORIDA RED SCALE (Chrysomphalus aonidum) infested 60 percent of groves (norm 62 percent); 7 percent economic (norm 12 percent). The low statewide level of abundance will continue. Only a few scattered infes- tations are likely to become important. Highest districts are Indian River, ridge and Bartow. PURPLE SCALE (Lepidosaphes beckii) infested 77 percent of groves; 10 percent economic. Population will remain near current low level. An increase may occur in scattered groves, especially where sulfur has been applied within past few weeks. Highest districts are ridge, Brooksville, west coast and Orlando. BLACK SCALE (Saissetia oleae), CHAFF SCALE (Parlatoria ergandii) , YELLOW SCALE (Aonidiella citrina), Pinnaspis stachani, CITRUS FLAT MITE (Brevipalpus lewisi), and 3 other COCCIDS are above average abundance, but none are presently of much importance.

COTTON INSECTS BOLL WEEVIL HIBERNATION SURVEYS IN NORTH AND SOUTH CAROLINA, TENNESSEE, MISSISSIPPI AND LOUISIANA - FALL 1961 The fall collection of surface ground (woods) trash samples (two square yards per sample) have been completed in 5 Southern States by State and Federal agencies to determine the number of boll weevil (Anthonomus grandis) adults that went into hibernation. The same areas were sampled as in the fall of 1960 in each of the States. A total of 3 samples was collected at each location in all States except Tennessee where 12 samples were taken. In North and South Carolina, 30 locations were sampled, with the number of counties per area from which samples were taken varying from 3 to 6. A total of 30 locations was also sampled in northeastern Louisiana; 5 each in East Carroll and Tensas Parishes and 20 in Madison Parish. In Mississippi, either 7 or 8 locations were sampled in each area. Wherever possible, the samples were taken from locations that could be sampled again in the spring of 1962. Average counts (live weevils per acre) this past fall exceeded those of the 1960 survey in McNairy County, Tennessee, and in areas 1, 2 and 4 in North and South Carolina, while those in the tri-parish area of northeastern Louisiana, all areas in Mississippi and area 3 of North and South Carolina were lower than in 1960 (see table on following page). The average of 3,025 live weevils per acre found in McNairy County, Tennessee, is the highest number of weevils ever found in the fall trash survey. During the past 26 years that records have been made in Madison Parish, Louisiana, there have been only 7 years in which a larger number of weevils have been found in ground trash than the 4,358 found in 1961. The average number of boll weevil adults found in the 2 other Louisiana parishes surveyed in 1961 was 9,038 in East Carroll and 17,593 in Tensas. In Florence County, South Carolina, the number of weevils found per acre (12,266) is 2.1 times the average for the 19 years that such examinations have been made. This is the highest number of weevils ever found in the fall examinations in Florence County. This could be because of the unseasonably warm weather this fall. The 1961 State average for Mississippi was 8,403 live weevils per acre as compared with 14,502 in 1960, 5,127 in 1959, 3,792 in 1958 and 6,715 in 1957. - 1108 - Number of Weevils Per Acre Area (County and State) 1960 1961 NORTH AND SOUTH CAROLINA South Central South Carolina (Orangeburg, Bamberg, 3,308 3,361 Dorchester Counties (area 1)).

SS = HAWAIIAN INSECT NOTES The following reports were submitted by the Hawaiian Entomological Society and were abstracted from the "Notes and Exhibitions" in the minutes of the November 6, 1961, meeting. SOUTHERN GREEN STINK BUG (Nezara viridula) - First found on the University of Hawaii campus on October 17, 1961, feeding on various vegetables, such as mustard cabbage, turnip, sweetpotato and garden beans. Det. by R. C. Froeschner. (Haramoto) . ? GREEN PEACH APHID (Myzus persicae) - Papaya mosaic, a destructive disease of Papaya, was recently confirmed from Puna, Hawaii, by University pathologists. Papaya mosaic has been present in the Waimanalo district of windward Oahu for several years, but this is the first record for the Island of Hawaii. M. persicae is the vector of this disease. Also, Panama wilt (Fuscarium cubense), a destruc- tive disease of banana, was confirmed from Honaunau, Hawaii, recently. This disease has been present in east Hawaii for many years, but was reported as a new record for the Kona district by the State Resident Entomologist at Hilo, Hawaii. (Davis). ORCHIDFLY (Eurytoma orchidearum) - This pest of cattleya orchids was found in an orchid collection at Kukuihaele near Waipio Valley, Hamakua district, on October 30, 1961, and marks a considerable extension of its range from Hilo, Hawaii, where the pest was first reported in 1952. (Davis). A PARASITIC BRACONID (Macrocentrus sp.) - Four specimens belonging to this genus, which appears to be a newly established immigrant, have been collected in light traps at Ewa and Waipio, Oahu, so far this year. The genus includes a large number of species, most of which appear to be internal parasites of lepidopterous larvae. None has previously been reported established in Hawaii, although at least one, M. ancylivorus Rohwer, which differs from the species at hand, has been purposely introduced. (Beardsley).
