The coolest weather in several weeks spread over the Northeast. Numerous severe thunderstorms spotted south from Texas to South Carolina. PRECIPITATION: Wide areas from California to the central Great Plains received no rain or only light sprinkles during the week. Numerous light to moderate scattered thundershowers occurred in the Northwest but most weekly totals did not exceed 0.50 inch. Much heavier showers in the Northeast and across the South from Texas to the Atlantic Ocean. Generous showers fell in the Northeast on Friday and Saturday with flash flooding resulting in parts of Pennsylvania. Heavy rain fell early in the week in North Carolina where Wanchese received 8.10 inches from Sunday afternoon to Monday night, June 21 and 22. Hail as large as baseballs fell at Bethlo, Florida, Tuesday afternoon. On Wednesday heavy thunderstorms became general from the central Great Plains to the western gulf coast. Palacios, Texas, received 3.96 inches Wednesday forenoon when 4.50 inches fell at Ottumwa, Iowa. More torrential rains fell in the afternoon with Corpus Christi, Texas, receiving 4.72 inches and Memphis, Tennessee, 2.28 inches. Much needed rain fell in all parts of South Carolina. One of the heaviest weekly totals, 6.58 inches, fell at Sumter, South Carolina. Strong winds raked western Montana late Saturday and early Sunday. High winds raised clouds of dust in the agriculatural areas of the Southwest. TEMPERATURE: The week began sunny and pleasant especially over the North Central States. Minimums were mostly in the 50's from the northern Rocky Mountains to New England and as far south as the central Great Plains. Warm humid weather pre- vailed over the Deep South with temperatures ranging from the 70's in the morning to the 90's in the afternoon. The West warmed early in the week and | the heat intensified as each day passed. Miles City, Montana, registered 100° or higher. By Thursday numerous locations in the Southwest set new high-temperature records. Afternoon maximums at Thermal and Blythe, California, reached 122° and Needles recorded 121°. In Arizona, Phoenix registered 116° and Flagstaff 95°. The extreme heat spread eastward. By Sunday, 100° maximums were common over the central Great Plains from Grand Forks, North Dakota, to Wichita Falls, Texas. Almost all areas in Nebraska and Kansas warmed to 100° or higher on Sunday. Meanwhile, cool temperatures became general over the Northeast with minimums tumbling to the 40's and low 50's as far south as Kentucky and Virginia. Weekly temperatures averaged above normal from the Pacific Ocean to the northern and central Great Plains and below normal from Texas to New England. Much of the Northeast averaged 3° to 8° cooler than normal. (Summary supplied by Environmental Data Service, ESSA.)

Curtis Wilson 2/, Robert E. Treece 3/ : and Richard E. Shade 2/ The cereal leaf beetle (Oulema melanopus (L.)) survey, designed to estimate larval populations and loss to the oats crop from foliar feeding damage, was conducted for the third season in 1969. Previous reports have been published by Wilson’ and Treece (1968), and Wilson, Treece, and Shade (1969). In the last report (CEIR 19(23) :409-417, 1969), it was pointed out that the cereal leaf beetle had not only spread rapidly, but was building up populations at a massive rate, particu- larly in eastern areas 300 to 500 miles distant from the focal point of initial infestation. An expanded survey of 222 counties (Illinois 12, Indiana 59, Michigan 58, Ohio 65, Pennsylvania 16, West Virginia 5, Wisconsin 4, and Ontario 3) con- firmed this in 1969. Data from this survey are tabulated in four tables. Table 1 summarizes losses from the cereal leaf beetle from 1967 through 1969. Table 2 shows a breakdown of losses by State districts. Districting is basically the same as that used by the Statistical Reporting Service. Some districts, however, have been subdivided into A and B areas according to infestation levels. Where counties that occur in the district are not listed, they have been excluded because cereal leaf beetle popula- tions were generally too low to be of economic significance. In Table 3, a comparison of infestation estimates for each of the three years the survey was conducted is tabulated. Some general infestation comparisons based on State averages are shown in Table 4. Surveys continue to reveal that ecological conditions have been more favorable for cereal leaf beetle buildup from north-central Indiana eastward than they have been in a westward direction from the same point (La Porte County). This is apparent in all tables. Losses occurred in Pennsylvania (Tables 1 and 2) after only two years of known infestation, while after six years in western Indiana and eastern Illinois, there are still no damaging populations. The comparisons in Table 4 show that population levels east and southeast of La Porte County in north-central Indiana are comparable to the high populations of Michigan, but south and west they appear static at low numbers. On the otherhand, in an eastward direction, five counties in West Virginia attained populations one year after detection equivalent to those found in western Indiana after six years. In western Pennsylvania counties, after two years, populations were threefold those in western Indiana. Comparative infestation levels are shown on the map on page 468. 1/ The following agencies cooperated to complete this survey: USDA, Plant ~ Protection Division; Indiana State Entomologist's Office, Purdue University; Ohio Department of Agriculture, Ohio Agricultural Research and Development Center; Michigan State University; Pennsylvania Department of Agriculture, Pennsylvania State University; Wisconsin Department of Agriculture; and the University of West Virginia. Estimates of oats acreage from which losses were calculated were obtained from the USDA Statistical Reporting Services of Indiana, Ohio, Michigan, and Pennsylvania. The value of oats was estimated at 59¢ per bushel by the Statistical Reporting Service Office at Lafayette, Indiana. 2/ Department of Entomology, Purdue University, Lafayette, Indiana. Agricultural Experiment Station paper no. 4074. 3/ Department of Entomology, Ohio Agricultural Research and Development Center, Wooster, Ohio. - 457 - “- 458 - With the exception of Indiana, cereal leaf beetle infestations increased and losses were greater in all of the States that had previously suffered losses. In Indiana and Illinois there was a downward trend in populations. In Illinois and parts of western Indiana they were sufficiently low that even traces of damage were not detected by this survey as in previous years. In contrast, conditions in an eastward direction from Indiana have been so favorable for the cereal leaf beetle that the loss in the oats yield increased 44 percent in 1969 over 1968. All population estimates are calculated from foliar feeding data and are based on consumption of approximately 20 percent of the foliage per larva per stem (Wilson et al, 1969). The index for loss of 3.17 bushels of oats per larva per stem infestation used in the 1968 report was also applied to the 1969 data.

Spotty showers dotted much of the Nation being heavier over the eastern half. PRECIPITATION: Most areas in the western half of the United States received no rain or only light sprinkles. The main exceptions included the Idaho Panhandle, western Montana, and some mountain localities in Arizona and New Mexico where a few weekly totals exceeded 1 inch. Showers were more generous over the eastern half of the Nation with many small areas receiving 1 to 2 inches of rain. Hail and high winds accompanied some of the heavier showers. Some spots in the East missed by the rains need moisture badly. TEMPERATURE: Ocean breezes cooled the Pacific coast last week but the heat intensified over the western interior with the mercury reaching 100° or higher over much of the West. Maximum temperatures Wednesday afternoon included: Ephrata, Washington, 100°; Portland, Oregon, 102°; Boise, Idaho, 100°; Winnemucca, Nevada, 102°; Grand Junction, Colorado, 100°; Needles, California, 117°; Prescott and Winslow, Arizona, 100° and 103°, respectively. A warm humid airmass lay over the eastern half of the Nation through most of the week. Sharp cooling dropped maximums near the Great Lakes late in the week. Green Bay, Wisconsin, registered 89° Friday afternoon but no higher than 74° Saturday. Greater contrasts occurred the following day in the northern and central Great Plains. Norfolk, Nebraska, recorded 98° Saturday but the highest temperature Sunday was 68°. Minimum tempera- tures from the Dakotas were about 15° to 20° colder Sunday morning than 24 hours earlier, dropping from the 60's Saturday to the 40's on Sunday. The Saturday and Sunday minimum temperatures at Sioux Falls, South Dakota, were 63° and 45°, respectively. Weekly temperatures averaged slightly below normal from the northern Great Plains to the Atlantic Ocean and from southern Texas to the Florida Panhandle and above normal over most other parts of the Nation. Parts of the southwestern deserts averaged 6° to 10° above normal.

Tropical storm Becky brought rains almost daily to portions of the Southeast. TEMPERATURE: Cold air poured into the North-central States early in the week dropping temperatures sharply. Monday morning readings plummeted to the 40's and 50's as far south as the northern portions of Kansas and Missouri. Spring- field, Missouri, registered 44° early Tuesday morning. These temperatures are near normal for September but are about 15° below normal for July. Warm humid weather continued over the Deep South and hot weather persisted in the South- west. Temperatures continued near normal over the West at midweek. Over the East, however, cool air continued to pour southward. Afternoon temperatures re- mained in the 70's and low 80's over a large area from Minnesota to New England and southward to the central gulf coast. Alexandria, Louisiana, registered The) Wednesday afternoon in contrast to the 92° maximum Monday. Afternoon maximums in the 70's are common over the Deep South in October. Late in the week, a High pressure area remained centered over the central Appalachians. This system brought the return of high temperatures and increased relative humidity to the eastern half of the Nation. By the weekend, maximums in the upper 80's and lower 90's were common from Minnesota to New England. Weekly temperatures averaged above normal over most of California, western Nevada, southwestern Arizona, and New England, and below normal over the rest of the Nation. Parts of the central Great Plains averaged.6° to 10° cooler than normal. PRECIPITATION: Generous showers fell early in the week along the gulf and Atlantic coasts while lighter, more scattered showers fell in the Southwest Interior, the Great Basin, and the northern Rocky Mountains. Scattered showers occurred over the northern and central Great Plains late in the week and light rains began in the Far Northwest on Sunday. Tropical Storm Becky was responsible for most of the other precipitation last week. Weather continued on 547. — (53) = SPECIAL INSECTS OF REGIONAL SIGNIFICANCE ARMYWORM (Pseudaletia unipuncta) - IOWA - Moth catches in light traps by county: Monona 38 (7 nights), Hancock 177 (7 nights), Plymouth 180 (11 nights), Louisa 3 (7 nights), and Dubuque 25 (5 nights).

TROPICAL STORM BECKY: Becky began quite humbly as a weak tropical depression that formed in the central Atlantic Ocean about 750 miles east of the Lesser Antilles late on July 14. The depression moved westward into the Caribbean, causing some shower activity over Cuba and the Florida Straits. Once reaching the Gulf of Mexico, the depression begans to intensify rapidly, and by afternoon on the 20th, a poorly organized tropical storm had formed. Becky moved northward and continued to intensify, Becky continued northward toward the Florida Panhandle with just below hurricane-force winds near the center, and hurricane warnings were issued from Fort Walton to Point St. Joe, Florida. The storm remained poorly organized, however, and by 3 a.m. on the 22d she had begun to weaken and turn slightly towards the northeast. At 5 a.m. on the 22d, hurricane warnings for the Florida coast were discontinued. Gale warnings remained in effect from Panama City to St. Marks, Florida. Tropical storm Becky moved inland near Point St. Joe at 7 a.m. on the 22d, bringing heavy rain and squalls to the Florida Panhandle. A total of 8.16 inches of rain was dumped on Tallahassee, which also recorded a sustained 29 m.p.h. wind with gusts to 44 m.p.h. A tornado destroyed three houses in Panacea, Florida, but no injuries were reported, and a high tide of 3 feet above normal was recorded at Panacea. Becky rapidly became extratropical, but the remnants of the storm continued northward bringing rain to the south- eastern and Middle Atlantic States. Flash flood warnings were issued for the Appalachian region. The storm moved through Georgia, Tennessee, and Kentucky, and by the morning of the 24th she had completely dissipated over Indiana, leaving behind a great deal of moisture.

Spotty nighttime thundershowers brought little relief from the heat and humidity. PRECIPITATION: Widely scattered showers and thunderstorms dotted the Nation last week, They occurred principally over the northern and southern Rocky Mountains early in the week from the northern Great Plains to New England and across the Deep South at midweek, and over the weekend. Gusty winds and hail accompanied some of the nighttime thunderstorms in the central and eastern parts of the country. A few tornadoes occurred but caused relatively little damage. Weekly totals ranged widely from none or only light sprinkles to near 1 inch over the West and from sprinkles to 2 inches or so over the East. A few spots in the East received more than 2 inches. TEMPERATURES: Cool weather prevailed only along the northern Pacific coast last week with temperatures reaching the 60's in the afternoons and dropping to the 50's at night. The Southwest continued hot with nighttime temperatures in the upper 70's and 80's and daytime maximums from the 90's to 110° or more, Maximums in the southwestern deserts averaged about 110°. Summer heat and high humidity continued in the stagnant air that lay east of the Rockies. At midweek, temperatures from the Great Plains to the Atlantic Ocean were mostly in the upper 80's and 90's except 100° or warmer over the central Great Plains. Nighttime minimums ranged from the 60's in the northern border States and Appalachian Mountains to the 70's elsewhere, The high relative humidity in this large stagnant airmass added to the discomfort caused by the high temperatures. Cooler drier air moved over the Northeast Sunday. Weekly average temperatures were below normal northwest of a line from Bakersfield, California, to Fargo, North Dakota, and above normal elsewhere, A large area from the central Great Plains to New England averaged 3° to 9° above normal.

Some relief from heat and humidity occurred in the Northeast. Flood producing thundershowers fell in parts of Iowa, Missouri, North Carolina, and Georgia. PRECIPITATION: Hurricane Celia dumped some heavy rains in the southern portions of Texas and New Mexico early in the week. Moderate to heavy Showers also fell in other parts of the country. More scattered in the central and southern Rocky Mountains, but not so scattered from the middle and southern Mississippi River Valley to the middle and southern Atlantic coast. Heavy rains in Iowa, 4 to 7 inches at some spots, caused lowland flooding along some creeks and rivers on Wednesday. The weekend brought scattered moderate to heavy showers from Missouri and Arkansas to the western portions of the Carolinas and southward to the Florida Peninsula, Many streams in North Carolina and in the Savannah area of Georgia overflowed their banks. Precipitation was light over the western half of the Nation with many western areas receiving no rain or only light sprinkles. TEMPERATURE: Typical summer heat continued over much of the Nation last week. Maximum temperatures reached the 60's along the Pacific coast but climbed much higher over the rest of the country. The southwestern deserts and the southern Great Plains warmed to 100° or higher on almost everday. Havre and Miles City, Montana, registered 100° Wednesday and Goodland, Kansas, recorded 108° Thursday. Kansas, Oklahoma and nearby parts of neighboring States averaged 3° to 9° warmer than normal, The mercury soared to 114° at Thermal, California, Thursday. The Deep South continued hot and humid with maximums in the 90's on most afternoons, Wednesday afternoon readings included 99° at Macon, Georgia, and 96° at Palm Beach and Miami, Florida. Sunny weather with a cooling trend occurred from the northern and central Great Plains to New England. Temperatures from northern Minnesota to Upper Michigan dropped to the 30's and 40's Tuesday morning but bounced up to the 80's by Thursday afternoon, A large area from Iowa to New York averaged 3° to 6° cooler than normal.

WEATHER OF THE WEEK ENDING AUGUST 17 HIGHLIGHTS: Summer heat continued last week over most of the Nation. Severe flash flooding occurred in western North Carolina. Drought intensified in many areas. PRECIPITATION: Early in the week, a quasi-stationary front extended from the southern Great Plains to the southern Atlantic coast. Heavy downpours, up to 10 inches or more, fell in the Appalachians north of the front. Mortimer, North Carolina, received 11.10 inches of rain in 48 hours ending at 2 p.m., Monday, August 10. Severe flooding occurred in the central and southern Appalachians. Moderate to heavy thundershowers occurred along the gulf coast during the first half of the week. Lighter, more scattered showers dotted the Rocky Mountains and adjoining Great Plains. Weekend showers occurred over the northern and central Great Plains, and along the gulf and Atlantic coasts. Wide areas from the Pacific coast to the western edge of the northern and central Great Plains received no rain last week. Many smaller scattered areas in the Central and East were missed by the showers. Drought intensified in many areas.

Texas in the southeast averaged cooler than normal. Mid-America received no rain or only light widely scattered showers. Generous rain fell along the gulf. PRECIPITATION: Early last week, showers occurred along and in the moist air south of a Slow moving front near the gulf and Atlantic coasts. Daily totals ranged to 1 or 2 inches and weekly totals were 3 to 4 inches or more. Lighter showers fell in northern Great Plains, the Great Lakes region, and in New England. Light scattered showers also fell in the northern and central Rocky Mountains. Heavy thundershowers with hail occurred at Las Vegas, Nevada, on Wednesday and over 4 inches of rain fell at Elko, Nevada, on Thursday. High pressure stretched along mid-America from New Mexico to New York producing cloudless skies and no rain or only light sprinkles from Arizona to Ohio and from Montana to Oklahoma. Only a few light sprinkles fell in Kentucky, Virginia, and North Carolina except along the coast of the latter States. Frontal activity produced weekend showers in the Northeast. Scattered showers also continued along the gulf coast and widely scattered thunder- showers occurred in the Great Basin and the Rocky Mountains. TEMPERATURES: Hot weather was present throughout most of the West last week. Temperatures averaged above normal except Slightly below along the coast as far south as San Francisco. On most days, maximums reached the 90's as far north as southern Washington and 100° or higher in the southwestern deserts. Thermal and El Centro, California, registered 100° Saturday afternoon. Temperatures were warmer than normal from the northern and central Great Plains, east across the Great Lakes to Massachusetts. A large area from Texas to central North Carolina averaged cooler than normal. The Atlantic coast areas and most of the Florida Peninsula averaged slightly above normal. A large High brought comfortable temperatures to much of the East last week. Early morning temperatures dropped to the 40's and 50's in the Northeast. Nights were clear and days were sunny. Afternoons were noticeably cooler and less humid than in the previous week. Temperatures of mid-America climbed to 100° or more on 1 or 2 days at midweek, reaching 103° at Bismarck, North Dakota, Chadron and North Platte, Nebraska, on Wednesday. Cooler air moved into the northern Great Plains and Thursday tempera- tures remained in the 70's over most of North Dakota with 90's in Nebraska. Early morning fog occurred over much of the East early in the week. It was especially widespread on Wednesday morning extending from Missouri to Maine, and from Lower Michigan to northern Georgia. Weather of the week continued on page 650. ROO i a SPECIAL INSECTS OF REGIONAL SIGNIFICANCE CORN EARWORM (Heliothis zea) - FLORIDA - Larvae 1 per 3 row feet of soybeans near Gainesville, Alachua County. (Whitcomb et al.). ALABAMA - Larvae infesting soybean pods in southern area; reported light to medium in many Geneva County fields. Cotton, corn, and peanuts maturing in area; soybeans more attractive for egg laying. Moth flights heavy. (Reynolds et al.). Larvae of H. zea, Spodoptera frugiperda (fall armyworm), and Feltia subterranea (granulate cutworm) light to medium and widespread throughout Covington County. Similar infestations throughout 9-county peanut area. (Pike et al.). SOUTH CAROLINA - Up to 25 larvae per row foot on pods and blooms of early planted soybeans and on leaves and blooms of younger plants in coastal Plain area. (Thomas). TENNESSEE - Increased moth activity in soybeans expected. Corn and cotton becoming less attractive; soybeans should be watched. (Gordon). VIRGINIA - Damaged 40 percent of ears in some Halifax County fields. Larvae averaged 10 per 100 sweeps in 3 Charlotte County alfalfa fields. (Hendrick). Widespread in peanut belt. Average per 100 sweeps and dominant stage by county: Sussex 18, second instar; Southampton 80, third instar; Nansemond 70, third instar; Isle of Wight 28, second instar. No larvae found in peanuts in Prince George County. Surveys of soybeans in Sussex, Southampton, Nansemond, Isle of Wight, and Prince George Counties indicate few larvae and less than 1 percent of soybeans in any field cut. Reports from southern Piedomont area indicate damage levels to soybeans similar. Based on blacklight catches, expect Nansemond County and surrounding areas to experience much damage next few weeks. Adult catches doubled at each light trap location, corn has dried in southern Piedmont and Tidewater areas. This will force moths to peanuts and soybeans in these areas. (Allen). MARYLAND - Corn earworm egg laying starting on soybean stems and pods in Wicomico County. Adults averaged 102 per night in blacklight trap at Salisbury. (U. Md., Ent. Dept.). DELAWARE - Increased, 35-40 per night in blacklight traps in Kent and Sussex Counties. (Burbutis et al.). NEW JERSEY - Adults increasing in corn, beans, and lettuce in most areas. (Ins.-Dis. Newsltr.). MICHIGAN - Still absent in blacklight traps throughout State. Populations should be late in appearing and limited in numbers. (Newman, Aug. 24). NEBRAKSA - Increasing rapidly at Lincoln light trap. Sweet corn ears averaged about 70 percent infested with third to fifth instars at Lincoln, Lancaster County. (Berogan, Keith). KANSAS - Ranged up to 0.2 per corn ear in 4 Greeley County fields; light in 4 Wichita County fields. (Bell). OKLAHOMA - Generally light to moderate in southwest area alfalfa, increasing rapidly in some areas. (Okla. Coop. Sur.). COLORADO - Larvae ranged 0-8 per 100 row feet of corn in Cheyenne and Kit Carson Counties. Infestations ranged 5-60 percent; damage light to moderate. (Johnson). UTAH - Very light in Cache County sweet corn. (Thornley). Light infestation developing in Davis County. (Knowlton, Stokes). CORN LEAF APHID (Rhopalosiphum maidis) - CALIFORNIA - This species and Dalbulus maidis (a leafhopper) increaSing in corn plantings in some areas of San Joaquin Valley. (Cal. Coop. Rpt.). GREENBUG (Schizaphis graminum) - COLORADO - Ranged 0-3,000 per sorghum plant in eastern area. Heavily infested fields scattered in Cheyenne and Kit Carson Counties and in Arkansas Valley. Averaged 250 (range 100-3,000) per plant in untreated fields or where one application made in Arkansas Valley; some plants killed in isolated fields. Ranged 0-2,000 per plant in Kit Carson, Cheyenne, and southern Yuma Counties; damage to sorghum light to heavy. (Johnson, Burchett). NEW MEXICO - Spotted infestations of up to 8 per leaf in grain sorghum in Roswell and Dexter area, Chaves County. (Mathews). TEXAS - Light to moderate in El Paso, Hudspeth, and Reeves Counties. Remained light to moderate in isolated fields in Pecos County; slight increase noted. Parasitized greenbugs in Pecos County remained light. Populations decreased sharply during past 14 days in most Panhandle counties. Parasites greatly reduced population throughout area. (Clymer et al.). KANSAS - Generally light in sorghum surveyed in southwest district. Predators and parasites generally heavy in area. Greenbug ranged 0-225 per plant (boot to soft-dough stage) in 18 fields checked in Stevens County, 0-300 in 6 - 638 - fields in Morton County, 0-10 in 2 fields in Stanton County, 0-10 in 3 fields in Hamilton County; none found in field in Greeley County. (Bell). NEBRASKA - Few remain in sorghum in east; some in northeast. Ranged 25-75 per lower leaf in 2 Thurston County fields August 25. Parasitism 65-70 percent. (Keith, Berogan). POTATO LEAFHOPPER (Empoasca fabae) - VIRGINIA - Adults 90 per 100 sweeps in one peanut field in Prince George County. (Allen). OHIO - Damaging populations (6 per sweep) built up on alfalfa in August with dry weather. (Flessel). WISCONSIN - Continues variable in alfalfa; more numerous on alfalfa on lighter soils than on heavier soils. (Wis. Ins. Sur.). SPOTTED ALFALFA APHID (Therioaphis maculata) - OREGON - Moderate in Vernal alfalfa in Hermiston area, Umatilla County. Averaged 20 per sweep in 1 field. Predators not abundant. Damaged seedling fields earlier this season. None found in Lahontan alfalfa. (Penrose). WYOMING - Averaged 6 per 10 sweeps in 8 scattered alfalfa fields of Weston, Crook, Johnson, Sheridan, and Converse Counties. Johnson and Sheridan are new county records. (Parshall). COLORADO - Increasing in Arkansas Valley; counts ranged 0-1,200 per 100 sweeps. (Burchett). KANSAS - None found in alfalfa field in Morton County; 120 per sweep in field of blooming alfalfa in Stanton County. In latter field, many lower leaves yellowing and some fallen. (Bell). WISCONSIN - Increasing in alfalfa but not in southwest as much as in sandy regions. Ten-fold increase noted over 14-day period in Spring Green area, Sauk County; ranged as high as 150 per sweep. (Wis. Ins. Sur.). TOBACCO HORNWORM (Manduca sexta) - ARIZONA - Larvae damaging tomatoes in Kirkland and Skull Valley areas of Yavapai County. (May). CORN, SORGHUM, SUGARCANE EUROPEAN CORN BORER (Ostrinia nubilalis) - NEBRASKA - Increasing at Lincoln, Lancaster County, light trap; declining at Concord, Dixon County. Second brood apparently not heavy in many fields. First or second brood infested 80-100 percent of plants; second brood averaged 1.7 per plant in about 10 fields checked in Burt, Thurston, Dakota, Dixon, and Wayne Counties. Most second brood in second to fourth instar and feeding mainly in ear tips. Many fields surveyed suffering from drought, probably most important factor in high second-brood egg and larval mortality. Populations heaviest in irrigated corn. (Hill et al.). IOWA - Third generation of moths emerging at Ankeny, Polk County; appeared in blacklight traps August 21. (Iowa Ins. Sur.). NORTH DAKOTA - Larvae ranged 8-176 (averaged 64) per 100 corn plants in Barnes and La Moure Counties. Infested plants ranged 8-44 (averaged 24) percent. First and second-generation larvae present. (Kaatz). WISCONSIN - Adults decreasing. Fresh egg masses still found, so danger not past. Egg masses 1+ per 10 plants in parts of Fox River Valley. Infested sweet corn ears ranged 4-44 percent. Controls generally effective. (Wis. Ins. Sur.). MICHIGAN - Moth counts at all blacklight stations moderate. Recovered 462 moths at Lenawee County station; about half last week's total. Heavy count means larval control period will be extended for another 10-12 days. Larval count 5 per 12 ears of sweet corn in roadside stand in Monroe County. (Newman, Aug. 24). OHIO - Moth flights peaked first 10 days of August; relatively large numbers still active in mid-August. Larval feeding should soon be notice- able with constant increase during September, due to staggered adult activity in August. (Roach). MARYLAND - European corn borer stalk infestations continue to increase in all sections; ranged 16-48 percent in Kent and Queen Annes Counties. Moths averaged 42 per night in blacklight trap at Salisbury, Wicomico County. (U. Md., Ent. Dept.). DELAWARE - Adults averaged 300 per night in blacklight trap in western Sussex County. (Burbutis et al.). NEW JERSEY - Eggs and larvae easy to find on late sweet corn. (Ins.-Dis. Newsltr.). GEORGIA - Severely damaged corn in Crisp County.

OHIO - Numerous adults feeding on silks in Licking County field corn. (Roach). WESTERN CORN ROOTWORM (Diabrotica virgifera) - ARIZONA - Averaged 1 per plant on 10 acres of corn at Kirkland, Yavapai County. (Ariz. Coop. Sur.). INDIANA - Adults taken in Fulton County by P. Lehker, and in Jasper, Starke, and Marshall Counties by Munter. These are new county records. (Gould). SOUTHERN CORN ROOTWORM (Diabrotica undecimpunctata howardi) - NORTH DAKOTA —- Adults collected from corn in Barnes County for a new county record. (Kaatz). CORN ROOTWORMS (Diabrotica spp.) - NEBRASKA - Ranged 1-6 per plant in 10 corn- fields in Burt, Thurston, Dakota, Dixon, and Wayne Counties. (Keith, Berogan). KANSAS - Adults, mostly D. virgifera (western corn rootworm), ranged 2-8 per corn plant in 4 Greeley County fields, I-3 in 4 Wichita County fields. (Bell). FALL ARMYWORM (Spodoptera frugiperda) - OKLAHOMA - Heavy in scattered sorghum fields in Jackson County. (Okla. Coop. Sur.). ALABAMA - Larvae, 2-6 per stalk, destroyed late sweet corn in Lee County gardens. (McQueen). WISCONSIN - First adults appeared August 21. (Wis. Ins. Sur.). WESTERN BEAN CUTWORM (Loxagrotis albicosta) - KANSAS - Most larvae in corn in Greeley County about full grown. Larvae averaged O-1 per ear in 4 Greeley County fields; up to 4 late instars per ear in 1 field. None found in Wichita County fields. (Bell).

General Vegetables - All stages of SWEETPOTATO WEEVIL (Cylas formicarius elegan- tulus) moderate to heavy in 4 acres of sweetpotatoes at Hoolehua, Molokai. (Fujimoto). TOBACCO FLEA BEETLE (Epitrix hirtipennis) trace to light (1 adult per 4 leaves) in one acre of young eggplant at Haleiwa, and in 0.25 acre of mature eggplant at Waianae, Oahu. (Kawamura). Field samplings of BEAN FLY (Melanagromyza phaseoli) infested petioles from home yardlongbean plantings from various areas on Oahu Showed high percentage of parasitism by Opius spp. (braconids). Percent parasitism by area; Waipahu 93, Ewa 95, Kunia 75, Wailua 99, Waianae 100, Kawailoa 83, and Kaneohe 67. Incidental parasitism by Halticoptera patellana (a pteromalid wasp) occurred in some areas, Similar samplings taken at these areas in October 1969, revealed heavy M. phaseoli infestation (up to 50 adults emerged per 20 petiole sample). (Au). Fruits and Nuts - COCONUT SCALE (Aspidiotus destructor) colonies light to moderate on pinnae of 20 percent of coconut tree fronds at Keehi Lagoon Park, Oahu. Adults of Lindorus lophanthae (a lady beetle) trace. Infestations, although generally light on Same host at most leeward areas, appear to be spreading. (Kawamura). Ornamentals - Larval broods of BLACK TWIG BORER (Xylosandrus compactus) found in wild bamboo orchid (Arundina bambusifolia) at Hilo, Hawaii. This is a new host record, (Davis).

On Maui, Tarvae collected at random under loose bark were: 124 M. indomita, 19 P. umbri- cola; on Kauai, 19 M. indomita, 1 P. umbricola. M. indomita now appears to be major cause of unusually heavy defoliation of monkey pod trees this year. (Sugawa, Miyahira). Beneficial Insects - MELASTOMA BORER (Selca brunella) heavy on young leaf buds of Melastoma bordering 3-mile strip along Kulani Road at Hilo, Hawaii; damage severe.

Else- where near normal temperatures are in prospect, Precipitation is expected to exceed normal over the Pacific Northwest, as well as eastern portions of the Great Basin, and in the gulf coast region. Subnormal totals are indicated for the upper and middle Mississippi Valley, the Ohio Valley, and the middle Atlantic Coast States. In unspecified areas near normal precipitation is expected. 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 7 HIGHLIGHTS: Rains in the Far Northwest dampened the forest and relieved the dangerous forest fire situation, Soaking rains fell in spots in the Great Plains and in some previously dry areas of the Southeast. Summer heat continued over much of the Nation, PRECIPITATION: As a high pressure area moved eastward from the northern Great Plains early in the week, it was replaced by a low pressure area with a cold front extending southward to Kansas and a warm front extending southeastward to South Carolina, Scattered thunderstorms occurred over much of the Nation except the Pacific Coast States and the Northeast. Heavy rains in southeastern Oklahoma and eastern Texas at midweek caused considerable flooding along many streams in that area. Sugarland, Texas, registered 3.84 inches in the 24-hour period ending at 7:00 a.m. Wednesday, and Tahlequah, Oklahoma, received 3.52 inches in the next 24-hour period. Shortly after midweek, light rains began to dampen the Northwest. These helped the fire fighters in that area, At some locations these were the first measurable rains since August 2. A number of violent thunderstorms occurred in the central Great Plains.

Below normal temperatures are expected along the Pacific coast and in the northern Plains. Elsewhere near normal temperatures are in prospect. Precipitation is expected to exceed normal over the Mississippi Valley, the Great Lakes, eastern portions of the Great Plains, and the north Pacific coast. Sub- normal totals are indicated for portions of the middle and south Atlantic Coast States, and also for California and the southern Plateau. In unspecified areas near normal precipitation is expected. 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 14 HIGHLIGHTS: The first winter storm hit the northern Rocky Mountains. Hurricane Ella brought beneficial rains and no significant damage to Texas. PRECIPITATION: Widespread sunshine covered most of the Nation last week. Pre- cipitation occurred along a cold front as it advanced southeastward. On Monday, these rains were scattered from Abilene, Texas, to Lower Michigan. Tuesday was another fine day, except in the showers which prevailed from Kentucky to New England. The northern and central Great Plains and eastward to Michigan and Indiana received scattered showers Wednesday. Thursday's showers covered the Northeast from West Virginia to New England. Light scattered rains continued along the gulf. The first major winter storm swept into Montana on Friday. A low-pressure area moved into the western part of the State from Alberta Thursday afternoon and by Friday noon 3 inches of snow covered the ground at Cut Bank. Elsewhere in Montana, the snowfall ranged from traces to several inches in the lower elevations and there were reports of a foot or more in the southern mountains. Snow accumulated to 14 inches on the highway in the Big Horn Mountains in Wyoming.

The snow hindered automobile travel and chains were required on many mountain roads. Cold rain fell south and east of the snow area. By Sunday the rain area extended from central Colorado to New England. Parts of the Corn Belt received from 1.00 to 2.00 inches. Most of Texas received beneficial weekend showers as the result of being caught between a cold front from the north and the peripheral circulation of Hurricane Ella in southern Texas. The hurricane brought beneficial rains but no important damage to Texas. California, Nevada, and parts of nearby States received no rain or only light sprinkles last week. TEMPERATURE: The approach of autumn brought the coolest weather of the season to much of the Nation last week. Skies were mostly clear. Temperatures dropped abruptly over the Great Plains as a cold front advanced southeastward. Aberdeen, South Dakota, registered 98° Tuesday afternoon but the highest temperature at Aberdeen Wednesday was 62°. Similarly, the maximum temperatures at Wichita, Kansas, on Wednesday and Thursday were 102° and 76°, respectively. Southerly winds on Friday brought the return of summer temperatures to the Great Plains, 86° at Aberdeen and 90° at Wichita. The Deep South and the Atlantic Coastal States as far north as Maryland continued warm until the weekend approached. Baltimore, Maryland, and Washington, D.C., registered 93° Thursday afternoon before a cold front passed. Northerly breezes brought subfreezing temperatures to the northern and central Rocky Mountains. Big Piney, Wyoming, registered 19° Friday morning. Subfreezing weather also occurred in parts of the central Great Plains. North Platte, Nebraska, recorded 30° and nearby Sidney, 29°, Friday morning. Minimums in the 30's and 40's were common from Utah to Minnesota and northern Wisconsin. Bryce Canyon, Utah, registered 28° Friday morning. Weekly temperatures averaged above normal over most of California and nearby parts of Nevada and Arizona and southeast of a line from southern New Mexico to northern Ohio, and below normal over most of the rest of the Nation. A large area from eastern Washington to western North Dakota and southward to the Nebraska Panhandle averaged 9° to 14° cooler than normal. (Summary supplied by Environmental Data Service, ESSA.)

BOO OO ogc Gocouounoc oll WEATHER OF THE WEEK ENDING OCTOBER 12 HIGHLIGHTS: An early winter storm spread subfreezing weather over the Rockies and nearby areas. Snow fell as far south as the Texas Panhandle. Generous rain fell ahead of the storm and along the frontal area. PRECIPITATION: Only meager precipitation fell early in the week. This included Tight rain in Washington and northwestern Oregon and scattered showers in southern New Mexico, southwestern Texas, and southern Florida. A large storm developed Tuesday over the northern Great Plains. Warm moist air streamed north- ward ahead of the storm setting off showers and local thunderstorms from the upper Mississippi River Valley to eastern Texas. Snow fell in the cold arctic air behind the storm, driven by strong northerly winds. By 2 p.m. Wednesday the snow at Wheatland, Wyoming, had accumulated to 12 inches. Three to 7 inches covered other parts of Wyoming. By evening, snow up to 12 inches covered the Colorado Rockies and 5- to 7-inch depths were common over Wyoming and western Nebraska. The snow pushed southward and eastward. By midnight Wednesday, moderate snow was falling as far south as Clovis, New Mexico, and Dalhart, Texas. Thursday evening and Friday morning, snow reached measurable depths at Grand Island and Lincoln, Nebraska. This was the first time either of those localities has seen more than a few flakes of Snow so early in the season. About midweek a tropical depression produced torrential rains in the Caribbean and caused flooding in parts of some of the islands. At dawn Friday, 16 rivers in Puerto Rico overflowed as the result of 25-33 inches of rain in 5 consecutive days. The flooding waters destroyed or damaged hundreds of houses and numerous bridges. Early Thursday morning, heavy local downpours of from over 5 inches to almost 12 inches in 6 hours caused flash floods in Oklahoma. As the weekend approached, light rains continued in the Pacific Northwest, snow fell from western Minnesota to eastern Kansas, bright sunny weather prevailed from California to western Texas and widespread thundershowers covered the large area from the Great Lakes to the Gulf of Mexico. These showers were especially heavy in southeastern Texas and southwestern LouiSiana. Beaumont, Texas, received 11.50 inches of rain Sunday.

WEATHER OF THE WEEK ENDING OCTOBER 19 HIGHLIGHTS: Most of the Nation enjoyed sunny, cool autumn weather. Snow fell in the central Rockies, in the Syracuse, New York, vicinity, and in northern Maine. Heavy thundershowers and a few tornadoes occurred in Mississippi. PRECIPITATION: Early in the week, precipitation continued along a front that stretched from the lower Great Lakes to southwestern Louisiana. Numerous locations in Louisiana and Mississippi received more than 1.0 inch in the 6-hour period ending at 8 a.m., Monday, October 5. Lake Charles, Louisiana, received 4.8 inches in the 24-hour period ending at that time. A few tornadoes occurred Tuesday morning in Louisiana and Mississippi, and many more in the forenoon in Mississippi. Damages were mostly light. A wide band of rainy weather spotted by thunderstorms preceded the front as it moved eastward toward the Atlantic Ocean. Snow flurries fell in southern Wyoming, northern Colorado, and western Nebraska, and a mixture of rain and snow fell from the northern and central Great Plains to the Ohio River Valley and the lower Great Lakes Wednesday. In the afternoon and evening, snow continued in southeastern Colorado and spread to northern New Mexico. Albuquerque, New Mexico, measured 5 inches late Thursday. Showers con- tinued ahead of the cold front from New England to the southern Atlantic States on Thursday. Light rain was still falling along the coast on Friday. Oklahoma and northern Texas received light, scattered weekend showers. The weekend also brought 5-10 inches of wet snow to some communities in the Syracuse, New York, area; 5 inches at Pompey and 10 inches at Marcellus, early Saturday morning. Several inches of snow fell in northern Maine Sunday forenoon. Elsewhere the weekend was mostly sunny due to the large high-pressure area that extended from the Great Basin to the Atlantic Ocean and from Canada to Mexico. TEMPERATURE: Sunny, mild weather prevailed over most of the Nation early in the week. Afternoon temperatures were mostly in the 40's and 50's in the North and the 70's and 80's in the South. The main exception to the fine weather was a cloudy, rainy area from Arkansas to the Great Lakes along and ahead of a front that separated two high-pressure areas. By Wednesday much cooler weather was spilling across the Nation's midsection. The front moved eastward and by Thursday high pressure dominated the weather from the Rocky Mountains to the Appalachians. This was accompanied by sunny, cool, dry weather over most of the Nation. North Platte, Nebraska, registered 19° Thursday morning. In contrast, Macon, Georgia, still in the warm air ahead of the front, registered 91° By Saturday the cold front had moved off the coast, and Sunday morning subfreezing temperatures were common in the central Appalachians and Piedmont. Columbia, South Carolina, registered 31° Sunday morning. The Atlantic Coast States averaged near or slightly warmer than normal in spite of the cool weekend. Else- where over the Nation, weekly mean temperatures were mostly below normal. A large area from the central Rocky Mountains to the middle Mississippi River Valley and southward to New Mexico and Texas averaged 6-14° cooler than normal.

Generous rains fell in the Deep South early in the week and over the weekend. Mid- week rains soaked the central and southern Great Plains. Light autumn weather prevailed over the northern Great Plains. PRECIPITATION: Skies were mostly clear as the week began. The main exception was an area from the central Great Plains to the Gulf of Mexico where clouds produced intermittent rain. Heavy amounts fell at a few places, 5.89 inches at Meridian, Mississippi, in the 24-hour period ending at 8:00 p.m. Monday. The rains spread eastward over the Deep South with numerous localities from Alabama to Georgia receiving 24-hour totals ranging from 2 to more than 3 inches. Light rains also fell in the Pacific Northwest as the week progressed. A series of fronts brought a changeable weather pattern, clouds and snow alternating with sunny skies. As one system moved to the Atlantic late Thursday another produced thunderstorms, some with winds and hail over the central Great Plains, and a third system, the most intense, dotted the Washington coast with winds up to 70 m.p.h., soaked coastal areas with heavy rains, and covered the mountains with snow. Snow depth accumulated to over 30 inches in some of the higher mountains of Idaho and Wash- ington. A large area from the southwestern deserts to the western portions of Kansas, Oklahoma, and Texas received no rain or only widely scattered light sprinkles during the entire week. To the other extreme, spots in the Deep South received over 4 inches. Key West, Florida, received 6.88 inches and 4 to more than 6 inches fell along the northern Pacific coast where the rainy season is getting underway. TEMPERATURES: High pressure continued to bring clear skies and moderate tempera-— tures to most of the Nation at the beginning of the week. As the week progressed, a series of cold fronts brought clouds and in general, smaller daily temperature ranges. The temperature range at Elkins, West Virginia, Monday was 45° from 22° in the morning to 67° in the afternoon. On Thursday the range was 8° from 52 in the morning to 60° in the afternoon. Subfreezing minimum temperatures occurred on 1 or 2 mornings over parts of the northern Great Plains and on several mornings over the central Rocky Mountains. Alamosa, Colorado, registered 22° Monday morning. A warmer trend occurred over the central and southern Great Plains during the week. Maximums in Oklahoma increased from the 60's on Monday to the 70's on Tuesday and the 80's on Wednesday and Thursday and dropped to the 60's and 70's on Saturday. Weather of the week continued on page 751.

CITRUS Citrus Insect Situation in Florida - Mid-October - CITRUS RUST MITE (Phyllocoptruta oleivora) infeste norm percent of groves; economic in 65 (norm 41) per- cent. Still in high range. Population on leaves highest for mid-October in 19 years of record. Near record high level on fruit. Decrease expected in November. Highest districts south, west, north, central, and east. CITRUS RED MITE (Panonychus citri) in 26 (norm 23) percent of groves; economic in 8 (norm 5) percent. Above normal but still at low level in all districts. Highest district central. Fall increase started. Scattered heavy infestations may be expected. TEXAS CITRUS MITE (Eutetranychus banksi) in 20 (norm 18) percent of groves; economic in 6 (norm 4) percent. Near normal and low in all districts. Buildup expected, especially in young groves. Highest district central. GLOVER SCALE (Lepidosaphes gloverii) in 60 (norm 56) percent of groves; economic in 6 (norm 7) percent. Near normal and moderate. Little change expected. Highest district south. PURPLE SCALE (L. beckii) in 52 (norm 53) percent of groves; economic in 3 (norm 2) percent. Normal and low. Increase expected but will not be severe. Highest district north. BLACK SCALE (Saissetia oleae) in 44 (norm 35) percent of groves; economic in 18 (norm 13) percent. At low level but above normal. Decrease expected through October; little change in November. Central district high. YELLOW SCALE (Aonidiella citrina) and CHAFF SCALE (Parlatoria pergandii) will remain very low in all districts. An ARMORED SCALE (Unaspis Citri) in 28 percent of groves; moderate to heavy in 15 percent. Record high level of September persisted into October. Decrease expected in late October with little change thereafter. WHITEFLIES infested 88 percent of groves; economic in 29 percent. Increased and near record high October level of year ago. Decrease to moderate level expected in November. Highest districts north and east. (W.A. Simanton (Citrus Expt. Sta., Lake Alfred)). Quarterly Citrus Insect and Mite Outlook in Florida - October through December - This outlook iS based on the asSumption that weather beyond the period of the current U.S. Weather Bureau 30-day Outlook will be normal. Therefore, the fore- casts given below cannot be viewed with the same degree of confidence as those in the "Insect and Disease Summary'' usually released twice each month by this station. CITRUS RUST MITE will continue in high range until December. Increase expected until mid-November followed by gradual decrease. Heavy infestations will occur in about 20 percent of groves. CITRUS RED MITE and TEXAS CITRUS MITE will increase steadily until year's end. Statewide population not expected to exceed normal low to moderate level. Heavy infestations of either species may build up rapidly in young groves. WHITEFLIES will increase in October, then decrease in November and December. Expected to be above average and in high range in most districts. GLOVER SCALE, PURPLE SCALE, YELLOW SCALE, and BLACK SCALE will gradually increase through December but not expected to become troublesome during rest of year. An ARMORED SCALE (Unaspis citri) will attain higher statewide level than in any =e Oli prior month due to intensification within groves and probable spread to previously uninfested groves by picking crews and equipment. MEALYBUGS will continue to decline to very low level. (W.A. Simanton).

Gurney 1/ Ten years ago, my friend Dr. Karlis Princis of Lund, Sweden, reported finding that the above Fabrician name applies to the species then almost universally known as Supella supellectilium (Serville) (Princis, 1960, p. 193). Personally, I wish that conservation of sSupellectilium (Serville, 1838) had been requested from the International Commission on Zoological Nomenclature. However, that was not done, and during the past 10 years there has been sufficient use of S. longipalpa (F,) 1798 to make any current effort to conserve supellectilium unwarranted. For this reason, I have recommended that S. longipalpa be adopted in the forthcoming edition of the Common Name List. That longipalpa has priority over supellectilium is clear. Fabricius (1798, p. 185) described Blatta longipalpa from “India orientali Dom. Daldorff," i.e., eastern India, Mr. Daldorff (collector). Princis (1960) examined the type specimen, a male, which also was recorded by Zimsen (1964, p. 614) as part of the Fabrician Collection in Copenhagen, Denmark, it having been obtained from a collection of Fabrician specimens in Kiel, Germany. Earlier, Shelford (1908, p. 468) had reported the unavailability of the type, but he was unaware of its presence at that time in Kiel. Judging from the travels of D.K. (or I.K.) Daldorff, as reported by Henriksen (1923, p. 121) and Zimsen (1964, p. 12), the type of longipalpa probably was collected in Tranquebar, which is in the State of Madras, on the eastern side of the Indian peninsula. It is not known how early longipalpa was established there, but Annandale (1907) said that it was "found throughout the Peninsular region." Daldorff arrived in Tranquebar in early 1791 and was there or nearby much of the time for 7 years or longer. Princis (1963, p. 249) mistakenly listed the type locality of longipalpa as "Ile-de-France (=Mauritius) ,"" probably by inadvertence while thinking in terms of supellectilium. Serville (1838, p. 114) described Blatta supellectilium from "Ile de France." Now known as Mauritius, located in the Indian Ocean about 500 miles east of Madagascar, the island was called Ile de France by the French who colonized it during 1715- 1810, but since then it has been under British administration. Prior to the French, the island was colonized by the Dutch, so there was a long history of international shipping to and from the island. Serville said that supellectilium was reported to be very common on Mauritius only in houses, occurring always amidst furniture, especially in the drawers of chests, and he referred to it (in French, "Blatte des meubles") as the furniture cockroach, a common name which has persisted in some countries. The species name is from the Latin noun "supellex," meaning household goods, furniture, utensils, and the like. The logi- cal depository for the type specimen of supellectilium is the Paris Museum, but Rehn (1947, p. 65) said that Dr. L. Chopard wrote him that the type had been lost. Even in the absence of a type specimen, however, it appears that what usually has been called supellectilium is indeed the species agreeing in description and behavior with Serville’s Species, and with longipalpa, so there is no reason to question the synonymy reported by Princis (1960). Related species of Supella have been reviewed by Rehn (1947, pp. 60-92) and Princis (1963, pp. 248-252; 1969). Evidence from related species and early records of longipalpa (usually under the name supellectilium) indicate clearly that the brown-banded cockroach is native to Africa, whence it Spread by association with man. Rehn (1945, 1947, pp. 68-70) has discussed its occurrence in Africa and the history of its growing distribu- tion. Prior to 1960 there was very little use of the name longipalpa in entomological literature, consisting of only about a half-dozen catalogue-style listings. Beginning in 1967, there have been at least 5 widely circulated papers: on 17 Systemic Entomology Laboratory, ARS, USDA, U.S, National Museum, Washington, DCE - 752 - - 753 - cockroach biology by Dr. Louis M. Roth, including an important review paper (Roth, 1970) in which the name longipalpa is used. Also, usage of longipalpa has begun in Canada, and a very strong precedent for accepting longipalpa has been its use by Princis (1969) in a carefully prepared world catalogue of the cock- roach fauna. Usage of the name supellectilium grew rapidly after 1900, as the species became more generally established and came to the attention of entomolo- gists in numerous countries, so that the list of references under that name by Princis (1969) occupies the equivalent of about 4 full pages in the Junk Catalo- gue format. In spite of this wide contrast in usage, the name longipalpa should now be adopted because of priority and the extent to which longipalpa is already being accepted in substantial literature. Family and ordinal placement - In the most generally used or "modern" classifi- cation, living (not fossil) cockroaches are placed in 5 families, in contrast to the traditional recognition of only one family (Blattidae) or of numerous fami- lies, as has been done by several entomologists. Accordingly, Supella now is placed in the family Blattellidae, following the conclusions of McKittrick (1964) , which are Supported in large part by current fundamental studies such as those of Roth (1970). Similarly, current“usage favors removal of cockroaches from the Orthoptera in a restricted modern sense and placing them as a suborder, the Blattaria, in the order Dictyoptera. The subordinal names Blattaria and Blattariae both were used for suprageneric categories earlier than Blattoidea and several other more recent names. Blattaria was introduced by Burmeister (1829, p. 32) and is preferable to Blattariae, established by Latreille (1810, p. 244), because the ae ending is the standard one for insect families and subfamilies, thus is misleading if used in a subordinal sense. Blattaria is now used in the revised Imms textbook (1960 printing) and many other standard works. The modern classification of this species, therefore, now stands as follows: Order: Dictyoptera Suborder: Blattaria Family: Blattellidae Genus: Supella Species: longipalpa (F,) References Annandale, N. 1907.

WEATHER OF THE WEEK ENDING NOVEMBER 2 HIGHLIGHTS: Flood producing rains fell in southwest Texas and nearby parts of Louisiana. The West continued relatively cool, the East mild. PRECIPITATION: A front stretched across the middle of the Nation from Wisconsin to Texas early in the week. A blocking high pressure area lay east of the front. By midweek, the southern end of the front had drifted only to Louisiana. A snow- storm moved out of the central Rocky Mountains to the central Great Plains. Several inches of snow fell Monday in parts of Nebraska and Kansas; 7 inches at Hays Center in the latter State. Severe thunderstorms, heavy showers, several funnel clouds, and a few tornadoes occurred in the warm moist air east of the front. Five to eight inches of rain fell in some localities in Arkansas on Tuesday forenoon, 8.20 inches at Jessieville, 6.12 inches at Little Fork. Deweyville, Texas, received 17.53 inches in the 24-hour period ending at 7:00 p.m. Central Standard Time and the rain was still falling at that time. Soaking rains occurred Tuesday night over a wide area from the Great Lakes to the Gulf of Mexico. As the far end approached, the southern part of the front swung east to Georgia. It brought rainy weather over a wide band from New York to Georgia. A low, centered over eastern South Dakota, produced snow flurries over the northern Great Plains and rain showers over the central Great Plains. A high in the Far West was accompanied by fair weather. Weather continued on page 762.

As the weekend approached, snow fell in the Rocky Mountains and in the Great Plains from the Dakotas to Oklahoma. Rain flooded lowlands along some streams in south-central Pennsylvania, northeastern West Virginia, and extreme northern Virginia late Thursday night. The weekend weather was mostly gloomy and depressing. The rains continued in the Pacific Northwest and generally inclement weather prevailed from the Mississippi River to the Atlantic Ocean TEMPERATURES: A cooling trend held afternoon temperatures over the northern Great Plains to near freezing; elsewhere there was little temperature change during the week. In both the West and the East maximums ranged from the 50's near the Canadian border to the 70's across the South. Freezing temperatures occurred on several mornings over the Great Basin, the Rocky Mountains, and the northern and central Great Plains. Douglas, Arizona, registered 28° on November 9, Subfreezing weather occurred on 1 or 2 mornings early in the week in the central Applachians.

A weekend storm brought subzero temperatures to the northern Rockies and the northern Great Plains, and strong winds accompanied by heavy snow and freezing rain to those areas eastward to the Great Lakes. PRECIPITATION: Light rain continued in the Far Northwest. Elsewhere precipitation was mostly light and widely scattered early in the week. Snow flurries occurred in the northern border States. High pressure dominated the West and the East and a cold front lay between. The front brought little precipitation, however, and fair weather prevailed until about midweek. By Thursday, Snow was occurring over a wide belt from the northern Rocky Mountains to the Great Lakes and cold rain fell from the central Great Plains to the middle Mississippi River Valley. Snow also fell in northern Maine and at higher elevations in the northern Applachians. A storm developed in the central Great Plains. The storm center moved from central Oklahoma to Illinois on Thursday afternoon and evening setting off severe storms. Tornadoes associated with the storm caused considerable damage and a few injuries in Arkansas. Precipitation became widespread over the eastern half of the Nation. Snow and fog reduced visibilities in the northern Great Plains. Late Thursday evening, artic air streamed southward at the western edge of the northern Great Plains causing intermittent snow accompanied by strong winds. This storm blanketed the eastern slopes of the northern Rocky Mountains and the northern Great Plains with 4-10 inches of snow. By late Sunday night, severe wintry weather and high winds with heavy snow or freezing rain covered a large area from the Great Lakes region to the southern Great Plains. TEMPERATURES: A cooling trend early in the week brought subfreezing temperatures over most of the Nation. The middle Atlantic coast escaped the freezing tempera-— tures, Savannah, Georgia, and Jacksonville, Florida, registered 28° and 29° respectively, however. Temperatures in the southern part of the Florida Peninsula dropped to the 40's, 41° at Fort Meyes and 46° at Miami. Southerly winds warmed the Great Plains. Grand Island and Lincoln, Nebraska, registered 62° Tuesday afternoon. As the weekend approached, cold temperatures and strong winds moved down across the western edge of the northern Great Plains. The temperatures at Cut Bank, Montana, dropped 17° in 30 minutes Thursday afternoon, and by Friday morning had fallen to 4 from 43° the previous afternoon. The weekend brought cold weather to much of the Nation. Subzero temperatures occurred in the northern Rockies Monday morning and subfreezing weather as far east as the northern Applachians, and as far south as Little Rock, Arkansas, and Memphis, Tennessee. Weekly mean temperatures averaged below normal from Montana and North Dakota to western Colorado, and from the Ohio River Valley to the Gulf of Mexico and the middle and southern Atlantic coast. The Great Basin and the wide band from Minnesota to Michigan southwestward to Arizona, New Mexico, and Texas, averaged warmer than normal.

Temperatures were quite erratic over the northern border States and averaged below normal. Heavy rains fell along the Pacific coast. Light to moderate precipitation occurred over the Northern States. Little or none over the South. PRECIPITATION: Only sparse precipitation occurred over much of Nation last week. The area with little or no precipitation extended from Arizona to the Atlantic coast. Cold air blowing across the relatively warm waters of the Great Lakes became loaded with moisture and dumped heavy snow on the south and east shores of the Lakes especially in western portions of Pennsylvania and New York where snow depths ranged up to about 12 inches. Some roads became completely blocked. A new surge of arctic air swept down into the northern and central Great Plains at midweek. Winds at Minot, North Dakota, gusted to 58 m.p.h. Wednesday. Heavy snow fell at some localities in the northern border States. As the weekend approached, a Pacific storm centered off the Washington coast was bringing rain along the coast as far south as northern California and snow in the coastal ranges and Cascades and eastward to the western edge of the northern Great Plains. At elevations of 3,000 to 5,000 feet in the Cascades snow sepths now range from 30 to 50 inches. Another low brought heavy weekend rains to southern California and heavy snow at Mount Shasta where 35 inches fell in 36 hours Friday and Saturday. TEMPERATURE: The week began with a cold wave pushing southward over central and eastern portions of the United States. On Monday morning temperatures in Iowa had tumbled close to the zero mark and by Wednesday morning many Floridians shivered in subfreezing weather with Tallahassee recording 13°. A warming trend occurred over the West. The mercury at Chardon, Nebraska, climbed from 7 Monday morning to 69° Tuesday afternoon and the minimum temperature at Salt Lake City, Utah, Wednesday morning was 57°. Denver, Colorado, registered 76° Wednesday afternoon, the warmest in that city so late in autumn. Temperatures were eratic over the northern Great Plains, climbing from much below zero in northern Montana Monday morning to 40° and 50° Tuesday afternoon, and tumbling back to near zero Wednesday morning as a new cold wave moved in from Canada. Imperial, Nebraska, registered 77° Wednesday afternoon before falling back to 27° Thursday and remaining below freezing all day Thursday. A warming trend pushed afternoon temperatures to 60° over Nebraska and Kansas on Saturday. Oklahoma and Texas warmed to 70° and 80°. North Dakota remained below freezing. Weekly mean tempera- tures were 6° to 12° below normal along the Canadian border from northeastern Washington to the Great Lakes and 6° to 12° above normal from the Great Basin to the Nebraska Panhandle, (Summary supplied by Environmental Data Service, ESSA.) = YO = SPECIAL INSECTS OF REGIONAL SIGNIFICANCE GREENBUG (Schizaphis graminum) - OKLAHOMA —- Ranged 2-3 per linear foot in wheat- fields in Caddo, WaShita, and Kiowa Counties.

COOPERATIVE ECONOMIC INSECT REPORT ESTIMATED LOSSES AND PRODUCTION COST ATTRIBUTED TO INSECTS AND RELATED ARTHROPODS - 1969 Introduction Prior to 1966, insect loss estimates were published in the Cooperative Economic Insect Report as individual reports. An attempt has been made for the fifth year to condense loss estimates from various States into a single report. This gives a more meaningful and better overall picture of the crop losses. The data have been compiled from the crop loss estimates submitted from 19 States. The entomologists submitting the 1969 estimates are listed below. H.F. McQueen Alabama J.E. May Arizona W.P.

TEMPERATURE: A southwesterly flow of the upper levels of atmosphere brought unseasonally mild weather to much of the Nation. On Monday afternoon, temperatures climbed to the 70's from the southern Great Plains to the Atlantic Ocean, and to the 80's in southern Texas and parts of the Florida Peninsula. Monday afternoon, a cold front accompanied by winds gusting to 60 m.p.h. and a wall of dust that reduced visibility to near zero moved into the Great Plains. At midweek, mild weather continued over the East as subzero weather moved into the northern Great Plains. At 2 pm Wednesday, the temperature at Cut Bank, Montana was 8° below zero while persistent southerly winds brought record breaking high temperatures to 21 States from Kansas and Oklahoma to Maine and Florida. Weekly mean temperatures averaged 12° to 18° below normal in northeastern Montana, 9 to 10° above from Colorado to West Virginia, and 10° to 15° above normal in Arkansas and eastern Texas.

Map. Centerfold. WEATHER OF THE WEEK ENDING DECEMBER 14 HIGHLIGHTS: Winter cold prevailed along our northern border. It was especially cold from Pennsylvania to New England. Mild temperatures predominated from Texas to Virginia. Heavy snow fell from Great Lakes to New England. PRECIPITATION: Fair weather continued over most of the Nation early in the week. The exception included light precipitation from the northern and central Pacific coast to the northern Rocky Mountains, and from the Great Lakes to the Northeast. For the most part, precipitation was sparse in the first half of the week although a blanket of fog covered central Oklahoma and much of Louisiana Wednesday morning. A change of weather pattern began to take shape about midweek. Moist Pacific air invaded the northern Rocky Mountains. As the storm system moved to the Great Lakes, another system brought mixtures of snow, sleet, and freezing rain, creating hazardous driving conditions across Upstate New York and northern New England. A foot of fresh snow fell at Massena, New York, increasing the depth at that location to 20 inches by early Wednesday evening, and by early Thursday 23 inches lay on the ground. By late Thursday, a major storm was sweeping across the Great Plains. Several inches of snow fell from northeastern Nebraska to southern Minnesota, and by Friday, the snow had spread eastward to the Great Lakes. A band of rain and freezing rain lay south of the snow belt. Showers and thunder- storms occurred in the middle Mississippi River Valley. The weekend brought inclement weather from the Great Lakes to the Atlantic coast. Heavy snow fell in the northern portion of that area. Madison, Wisconsin, received 16 inches, the greatest 24-hour amount and the greatest storm total of record for that station. Freezing rain coated wires, trees, and streets south of the snow area. Rain fell further south, but parts of the Deep South received no rain. Some areas in Georgia received rain on Saturday after three weeks of dry weather. Forest fire danger increased in the rainless areas. By late Sunday, snow fall intensity was decreasing in the Northeast, but a Pacific storm was approaching the western coast. TEMPERATURES: Fair weather prevailed over most of the Nation early in the week. Monday afternoon temperatures in the 60's were common in mid-America as far north as Nebraska. Montana and North Dakota registered maximums in the 40's. The Northeast was cool with afternoon readings near freezing. In the Southwest, the mercury approached the 80° mark with 82° at Thermal, California, and at Tucson, Arizona. Subzero temperatures occurred in northern Maine Tuesday morning. The warming trend continued in mid-America with Grand Island, Nebraska, recording 73° Tuesday afternoon. Cooler air moved into the northern Great Plains Wednesday when much of Montana and the Dakotas remained below freezing. The East warmed at midweek. Washington, D.C., was about 20° warmer on Saturday afternoon than 24 hours earlier. Weather of the week continued on page 834.

Roseau, Minnesota, registered 36° below zero and snow in Washington accumulated to more than 100 inches above 5,000 feet. TEMPERATURES: Clear cool invigorating weather prevailed over much of Nation early in the week. Subfreezing temperatures occurred as far south as the Gulf States on Monday December 14. Temperatures plunged to below zero at some northern locations in sharp contrast to 60° temperatures in parts of the South, At 7 a.m, Wednesday temperatures ranged from 25° below zero at Houlton, Maine, to 74° at Key West, Florida, A gradual warmup occurred over the East during the week. By Saturday, maximums were reaching the high 50's and low 60's as far north as the Ohio River. Sunday was slightly cooler, A cooling trend over the northern Rocky Mountains and the northern Great Plains dropped temperatures to below zero on 1 or 2 mornings. Big Piney, Wyoming, registered 26° below zero Sunday morning. One of the coldest temperatures of the week occurred at Roseau, Minnesota, on the 21st, when the mercury plunged to 36° below zero, Temperatures averaged below normal from the Pacific Ocean to the Great Lakes in the North and to the Continental Divide in the South, Eastern New York and New England also averaged cooler than normal, Above normal average temperatures prevailed from Oklahoma and Texas to the middle Atlantic coast, Most of Montana, Wyoming, and the Dakotas averaged 6° to 16° below normal, PRECIPITATION: Precipitation was occurring in three areas early in the week. One low pressure system centered north of Lake Erie was causing snow flurries from Michigan to Maine, but accumulations were slight. A low centered over northeastern New Mexico was dumping snow on the southern Rocky Mountains. A third storm pro- duced snow in coastal ranges and the Cascades in Washington and Oregon, Precipi- tation in the Northwest was accompanied by strong winds. Cape Blanco registered 86 m.p.h. gusts Tuesday. Several inland stations recorded wind gusts exceeding 45 m.p.h. By Tuesday morning, typical winter weather had replaced clear skies of the previous day over much of the Country. At midweek the Pacific storm continued to batter the Northwest, while another low centered over southwestern Arkansas dumped heavy snow in eastern Kansas and northern Missouri, Heavy thunderstorms occurred in the Deep South. By afternoon, precipitation was widespread from the Mississippi River to the Atlantic Ocean, As the storm moved northeastward Thursday, it dumped snow at the rate of l-inch an hour at some locations in the Northeast. Portland, Maine, received 20 inches in 12 hours on Thursday. The weekend brought rain along the Pacific Coast, snow in the western mountains, northern border States, and the Northeast, and freezing rain in some areas south of the snow belt. Light rain or drizzle fell from Texas to the southern Appala- chians. Weekly precipitation totals ranged up to 4 inches or more along the Washington coast to less than an inch inland in the Far West. Totals across mid- America were generally from traces to less than 0.25 inch, Totals in the Deep South increased to 2 to 4 inches along a narrow band from New Orleans, Louisiana, to Wilmington, North Carolina. In Washington, snow has accumulated to over 100 inches at elevations above 5,000 feet.
