THE MORE IMPORTANT RECORDS FOR JULY

Grasshoppers continued to be the most serious problem of the year. Rather heavy migrations were under way over much of. the infested area. In the southern part of this area — Nebraska and Colorado — the outbreak was probably as heavy and widespread as the outbreaks in the late 70' s.

A slight outbreak of Mormon crickets occasioned considerable alarm in the' Dakotas during the month. In the western part of the range of this insect egg laying began the second week of July,

The Japanese beetle was appearing in unprecedented numbers. Around the periphery of the infested area reports of heavy emergence have been received from the metropolitan area surrounding New York City, and from Connecticut, Rhode Island, DolaSare, and northeastern Maryland.

The recently introduced weevil Naupactus leucoloma Boh. 'reached its peak of emergence the second week of July. In some fields in Florida it was emerging at the rate of about 500.000 beetles per acre. The insect was discovered at Laurel, Missi, on August 9*

Another weevil but recently reported from this country, Calomycterus setarius Roelofs, again appeared in numbers in parts of Connecticut.

A heavy outbreak of the variegated cutworm occurred in Wisconsin, Minne- sota, Nebraska, and South Dakota. In many places the outbreaks were unprece- dented.

Unusual numbers of the sugar beet webworm were reported from North Dakota and the Groat Basin States.

The white-lined sphinx appeared in startling numbers over a very wide area extending from Michigan westward to the Dakotas and Idaho.

Serious armyworm outbreaks occurred over much of the United States, reports having been received from the New England, Middle Atlantic, East Central, West Central, and Great Basin States.

The European corn borer was much more destructive than last year in the New England States and New York.

Codling moth abundance was variable, New Jersey reporting the heaviest infestation since 1933 and Delaware the lowest since 1929» In general, in- festations appear to be about normal.

The flatheaded apple tree borer is still destructive ^ver much of the area that has suffered severe drought during the last few years.

-263-

-26H-

Blister "beetle injury was reported generally from New England to Kansas and trie Gulf.

Serious damage to tomato fruit from the corn ear worm was reported from the Middle Atlantic and East Central States. The usual damage to sweet corn is being generally reported. The infestation in southern California is ap- parently increasing.

Unusual injury to potatoes "by leafhopper was reported from the Middle Atlantic States and from some parts of Indiana and North Dakota.

Prom New York westward to South Dakota the imported cabbage worm was generally destructive.

False chinch bug attacking sugar beets is reported from Idaho south to Arizona and east to Oklahoma .and Texas.

The boll weevil is causing more damage in South Carolina than it has in a number of years. Infestation, is also quite heavy in northern Georgia. In the Gulf region, although populations are not unusually high, weather favor- able for weevil development has increased the hazard. Heavy infestations are also reported from eastern and southeastern Texas.

Cotton flea hopper damage was reported from northern Georgia westward to southern Texas.

A half-grown cotton leaf worm was found on July. 22 in southern Georgia and one on July 13 in southern Alabama. Up to August 2, however, no leaf worm had been reported from Louisiana or Mississippi.

Gypsy moth infestation in New England is heavier than it has been for many years and very serious defoliation is generally reported.

Severe defoliation by the forest tent caterpillar is also reported from New England and Minnesota.

Cankerworms are generally reported from Nbt2[ England, and the most serious outbreak of the spring cankerworm ever to be reported is under way in Nebraska.

The bagworm is generally prevalent from New England and the East Central States southward to the Sulf.

A heavy infestation of the spruce budworm on ponderosa pine is reported from Colorado.

THE MORE I IMPORTANT ENTOMOLOGICAL FEATURES IN CANADA

In areas in Saskatchewan where crop conditions have been poor, and control measures consequently generally neglected, grasshopper ravages were completing the work of the drought. Local dispersal of the insects resulted in severe defoliation of remaining crops throughout west- central and northwestern parts of the Province, with heavy reduction in feed supply for livestock. Infestations are spreading north and north- eastward into many new districts. In Alberta there was little loss from grasshoppers up to the end of June and the use of poisoned bait was proceeding with satisfactory results. However, with the advent of hot weather in July, the grasshoppers were migrating into grain fields, and some districts reported losses in spite of the stenuous poisoning campaign. Toward the middle of July hoppers were migrating into southern Alberta and losses were increasing in drier sections, particularly in the southeast. Severe damage was still occurring in southern sections, in the latter part of the month, insspite of recent rains. In Manitoba the distribution of poisoned bait was necessary only in the extreme south- west, and excellent kills were obtained. Late in July, grasshoppers in the Red River Valley were reported dying of fungous disease. By mid- July, a large proportion of the grasshoppers over extensive areas of the Prairie Provinces had reached the adult stage.

In areas of Saskatchewan and Alberta affected by extreme drought, the destruction of host plants may result in a marked reduction of the wheat stem sawfly population, and reduce the economic importance of the insect in such areas for some time to come. In the Rockyford, Nobleford, and Barons districts of Alberta, wheat is severely infested.

The armyworm is causing considerable loss of excellent stands of oats, other grains, and grasses in a wide area in eastern Saskatchewan and has defoliated some fields of oats and barley at scattered points in Manitoba.

Severe outbreaks of the western chinch bug occurred in old brome- grass pastures in the Red River Valley, Manitoba and, where the insects attacked wheat in numbers, completely destroyed the crop.

Weather conditions in southwestern Ontario were ideal for pupation and emergence of the European corn borer. The first moths and eggs were found at Chatham on June 28.

-266-

Extcr.sive outbreaks of blister beetles of several species again occurred in the Prairie Provinces. The abundance of these insects is reported to be associated with repeated outbreaks of grasshoppers, on the egg pods of which the larvae feed.

The Colorado potato beetle appears to be more abundant and in- jurious than usual in Ontario and part's of Quebec. A marked reduction over previous years is noted in Manitoba.

Heavy infestations of flea beetles of several species were reported on field and garden crops in various parts of' Eastern 'Canada and in Manitoba.

Important damage by the cabbage maggot was reported in Ontario and on Prince Edward Island. In the latter Province and in eastern Ontario the onion maggot is also causing notable 'Injury.

Extensive flights of the diamondback moth occurred in southern Alberta and Saskatchewan in spring, and the larvae have caused rather severe damage to cruciferous crops.

The first brood, of codling moth was heavy in southern Ontario, as a result of the large carry-over from 1936. There were no serious worm infestations, however, in well-sprayed orchards.

The infestation of oriental- fruit moth continues very low in peach orchards of southern Ontario.

The apple aphid and the black cherry aphid are troublesome in orchards of the Okanagan Valley, British Columbia.

An infestation of the spruce bud worm is present over a large territory in Manitoba and Ontario. It apparently extends from the SandiLands Forest Reserve, Manitoba, to the Eagle River, Ontario, and appears to bo spreading eastward.

The spruce mite, which has long been a serious pest of planted spruce in the Prairie Provinces, has this year assumed outbreak pro- portions, and reports indicate that defoliation is proceeding rapidly.

An extensive and , injurious infestation of the yellow-headed spruce sawfly has developed in northern and central Manitoba, .Saskatchewan, and Alberta.

-267-

The European pine shoot moth, which was largely eliminated in the Niagara district, Ontario, by the severe winter of 1933~3^» nas recover- ed and increased to a some what alarming extent.

Severe defoliation "by the satin moth is reported on Prince Edward Island and Cape Breton Island. Defoliation also occurred at Monston ~nd in Westmoreland County, New Brunswick. A new infestation was dis- covered at McAdan, New Brunswick. Little damage was done this year at Amherst, Nova Scotia, where the out "break has "been much reduced.

GENERAL FEEDERS

GRASSHOPPERS (Ac'rididae)

Vermont. H. L. Bailey (July 2'6) : The lesser migratory grasshopper (Me- lanoplus atlanis Riley) is abundant in West River Valley, Windham County, southeastern Vermont.

Georgia. .0. I. Snapp (July l): "Grasshoppers originating in wheat stubble have moved to adjoining cotton and corn and have caused considerable damage *to those crops at Marshallville, in central Georgia. (July 13)t Grasshoppers are unusually abundant and have caused consider- able damage to old corn at Port Valley.

C. H. Alden (July 19) J Severe damage to corn by grasshoppers. Most abundant species were M. differentialis Thos. and Dissosteria Carolina L. Grasshoppers are generally more abundant and injurious in the southern half of the State than they have been in many years.

Florida. J. R. Watson (July 23) : Grasshoppers, particularly the so-called "bird grasshopper" (Schistocerca americana Drury) , did much damage in the northern part of Alachua County, where corn was badly riddled over a considerable section.

Ohio. T. H. Perks (July 22): But one report has reached this office con- cerning grasshopper damage. This came from Brown County, southern Ohio, where the insects were reported injuring tobacco and soybeans on a farm. During the wheat- insect survey grasshoppers were found to be present in only moderate numbers.

Indiana. J. J. Davis (July 26): Grasshoppers are abundant in more or less isolated spots throughout the northern half of the State, with great- est prevalence in the we stern part, especially near the Illinois State line. Although most of the trouble is in the field crops, a number of reports of injury in gardens were received the first half of the month.

Illinois. W. P. Flint (July 2l): Grasshopper damage continues to be moderate over much of the infested area in the State. There is considerable migration to corn and soybeans, now that the small grain is being cut. Hoppers in -all cases are showing distinct preference for soybeans over corn.

Minnesota. A. G. Ruggle3 (July 19): Grasshoppers being reported from

all southern and western counties of the State. Not alarming, but unless controlled will build up.

Missouri. L. Haseman (July 2^) : The infestation in Missouri continues to be serious. Some second-brood emergence, apparently of Me- lanoplus mexicanus Sauss.

-269-

North Dakota. F. G. Butcher (July IS): Grasshoppers continue to be the most important insects in all counties, except in the northeast corner of the State, with M. mexicanus the predominant form. Most of the important species are in the adult stage. Localized mi- grations have been commonly reported during the last 2 weeks over most of the infested area but the hoppers have not spread out ex- tensively into noninfested areas. Control operations are slowing down considerably in some areas, since farmers are becoming dis- couraged because of the continued invasion by adult flights. M. bivittatus Spy, M. packardii Scudd. , M. mexicanus, and M. femur - rubrum Deg. have been observed mating and M. bivittatus has started laying eggs.

South Dakota. H.. C. Severin (July 2): Many grasshoppers are now fully

winged. Considerable migration is taking place. Hordes of grass- hoppers are moving into South Dakota from the south and many are leaving the State for regions elsewhere. Owing to harvest, the poisoning campaign has lagged. (July 3): M* mexicanus is the species most harmful in South Dakota. Of considerable less im- portance are M. differentials and M. bivittatus. A very serious infestation covers much of eastern South Dakota, east of the Missouri River. Much less serious west of the Missouri, but become more abundant near the Black Hills. Considerable damage has alr§ady been done to small grain, corn, and garden crops.

Nebraska. 0. S. Bare (May 20 to July 20): Grasshoppers proved to be

the outstandingly major pest in the State during the period here covered. The grasshopper infestation is unquestionably the heaviest and most widespread since the pioneer "grasshopper years" of 187*+- 76. Every county in the State has experienced serious crop damage, with the possible exception of five or six counties in the sandhill area, and more or less scattered but somewhat destructive infesta- tions have occurred there. M. bivittatus and M. mexicanus had hatched in large numbers by May 20, and hatching of those species continued into the early part of Juno. M. different ialis had barely started to hatch on May 20, but developed rapidly and continued well through June. The first noticeable crop damage was reported about May 20, and became increasingly heavy throughout the 2-month period. Spring seedings of alfalfa and clovers were badly damaged or destroyed and spring-planted grains and older alfalfa and clover fields in many sections were badly stripped. Serious damage to corn began early in June and has continued to the close of the period covered by this report.

M. H. Swenk (July 20): Po.rasites of grasshoppers have begun to appear in force. The amount of parasitization by the sarcophagid fly Sarcophaga kellyi Aid. had by July 20 become quite large. Dead M. bivittatus, M. different ialis, M. femur-rubrun, .and M. mexicanus, collected from two farms near Lincoln from June 25 t^> July 1, began giving up maggots of this species within 2U hours. Of the 691 grass- hoppers collected on one farm, a total of 125 sarcophagid noggots

-270-

emerged and 103 pupated and successfully reached the adult-fly stage, giving a total successful parasitization of IS percent. Even heavier parasitization has been reported from western Nebraska, especially in Garden County, where the toll of Sarcophaga kellyi on the grasshopper papulation has become obvious on'Some farms. Parasitization of grass- hoppers by St kellyi was. first reported from Hall County on June 22« A. great abundance of the mite Eutrombidium trigonum has also developed on Nebraska grasshoppers. The first reports of the presence of these

., mites in abundance came from Jefferson, Boone, and Dodge Counties on June 25, 26, and JO, resoectively, and reports have since become

. .' general over the State. Since the end of June, and especially during July, there have been reports of heavy infestation of grasshoppers, especially of K, bivittatus and M. differentialis with hairworms (Gordiacea). These have come from Richardson County north to Douglas and Madison Counties and west to Furnas County.

Kansas. H. R. Bryson (July 22): Although grasshoppers are abundant in most sections of the State, the situation is not alarming and not as bad as last year. . In some localities parasitization is playing an important role in- the natural control. The most common parasites are the dipterous ones and the horsehair snake (Mermis sp.)« In northeastern Kansas 50 percent parasitization has been observed in some localities, but the number of reports received by corre-r spondence have been comparatively few. This is no doubt due to the effective organized control campaigns that have been instituted in the counties. Such campaigns are usually accompanied by the dis- tribution of information that would ordinarily be sent out in correspondence. Most of the species involved at present are Me- lanoplus bivittatus, M. mexicanus, M, differentialis, ' and M. femur- ■ ruorufli' The lubber grasshopper Brachystola magna Gir# is more abundant on the highlands north and around Manhattan that it has been for several years.

Tennessee. G. M. Bentley (July 2l): The outbreak of M. ' femur- rub rum and M. differentialis in several counties has been satisfactorily controlled. The nurserymen of Franklin County have reported that the peach leaves on young growing stock were badly eaten by grass- hoppers before they knew of their presence.

L. B. Scott (July 16): Grasshoppers are still present in large numbers, with the most noticeable damage in tobacco. Where no baits have been applied the damage amounts to as much as SO percent.

Arkansas. D. Isely (July 2^): It has been estimated that 335,000 acres of

crop land had potentially. injurious infestation of grasshoppers during the latter part of June and the early part of July. The greater part of this infestation, was M.-. differentialis. In some spo'ts, however, "M. mexicanus was the dominant species, and its appearance was earlier in June,. The most seriously injured area, was . in the Delta between the St.' Francis and Mississippi Rivers, in .northeastern- Arkansas, with some heavy infestation in the counties immediately '.vest of this. The

-271-

outbreak has been brought under control fairly well. In the north- western part of the State, where injury was most severe in 193&> grasshoppers have been less numerous than average, except in a few spots. Where injury has occurred, the destructive species have been M. differentialis and M. femur- rub rum. M. bivittatus, ordinarily regarded as an unusual species in northwestern Arkansas, has been abundant in a few spots,

Oklahoma. F. A. Fenton (July 20): Grasshoppers continued to be the most injurious insect pest in Oklahoma during the past month. The most common species, M. differentialis, has now largely reached the adult stage and is prevalent in alfalfa and cotton fields. Most of the crops, with the possible exception of alfalfa, are beyond the point where they can be injured by these insects.

C. F. Stiles (July 22): Grasshoppers continue to be very numerous in Oklahoma, except in the extreme southeastern counties, and in some localities there are outbreaks. Corn, cotton, and alfalfa are suffering most at this time. Many cornfields are being completely defoliated and the third cutting of alfalfa is being seriously damaged, where the hoppers have not been poisoned. The species doing the most damage are M. bivittatus, M. differen- tialis, and M. mexicanus. The species most prevalent in the western Panhandle counties is Dissosteira longipennis Thos.

Alabama. J.. M. Robinson (July 21): In Jackson County grasshoppers were reported on July 17 as being a very serious threat to field crops. The bird grasshopper (Schistocerca americana Drury) is causing serious concern at Deatsville attacking over 2 acres of cotton and about 1 acre of oat stubble. Adults vrere emerging on July 19*

Mississippi. C. Lyle (July 2]>) : Schistocerca americana Drury was damaging corn and cotton at State College about the middle of July. It was necessary to use poisoned bait to control them. Infestations of grasshoppers have been found in Warren, Washington, and Quitman . Counties, attacking cotton and other crops.

Texas. F. L. Thomas (July 23): Grasshoppers were damaging wheat on June 26 and 27 in Hemphill and Ochiltree Counties. Fifty percent of the wheat heads were on the ground at Canadian in Hemphill County and also in Dallam and Sherman Counties, of the north Panhandle area.

Idaho. C. Wakeland (July 2l): Small local outbreaks of grasshoppers are being baited in Bear Lake, Bannock, and Caribou Counties, south- eastern Idaho; in Fremont County, northeastern Idaho; in Lincoln and Gooding Counties, south-central Idaho; and in Payette County, southwestern Idaho. The population is increasing and we expect outbreak conditions in larger areas in 1938.

Utah. G. F. Knowlton (July 29): Grasshopper conditions are becoming increasingly serious as late-hatched nymphs increase in size.

-272-

Large populations are encountered in many localities in northern Utah. Alfalfa is being seriously damaged at Liberty, Eden, and Smithfield by grasshoppers, ^percent of which are nymphs. More of the grasshoppers are winged in central and southern Utah. Pastures are being damaged at Dry Lake, Sardine Canyon, and Benson, (July 19) : Grasshopper damage is very severe to alfalfa in the Newton-Clarkston area. Damage is very severe in many parts of Millard County.

Arizona. 0. L. Barnes (June 28): First- ins tar nymphs of the second -generation of M. mexicanus were appearing generally in alfalfa fields in the Blaisdell district, 12 miles cast of Yuma, on June 18. Populations ranged from 1 to $ per square yard. A. few nymphs were in the second instar. Pirst-generation females were first noted on April 22 and were • numerous by May 5» In 1936 first-instar nymphs of the second generation were first taken. June 1J.

MORMON CRICKET (Anabrus simplex Hald. )

North Dakota. P. G. Butcher (July 19): Pirst actual reports of damage by Mormon crickets in North Dakota were obtained this month. These insects are alarmingly numerous, especially in southern Burleigh County, Emmons County, and in McKenzio County. Some crop injury has been reported in these areas.

South Dakota. H. C. Severin (July 3)-* A. simplex has increased

enormously in abundance in. South Dakota this year. This is the first time in history when complaints have reached us that Mormon crickets are doing considerable damage in the State. The Mormon crickets are found in large numbers, chiefly west of the Missouri River, but they are numerous in the Ree Heights Hills, as far east of the Missouri River as Hand County. (July 2l): The Mormon cricket situation is becoming more serious, especially in Butte and 'Lyman Counties.

Montana. H. B. Miller (July 22): Mormon crickets were laying eggs in Powder River County on July 10.

Utah. C. J. Sorenson (July 21): Mormon crickets arc very abundant

in Juab and Tonele Counties. They are only moderately abundant in Millard County, because of control work.

SUGAR BEET WIREWORM (Limonius californicus Mann.)

California. R. E. Campbell (July 2U): A letter just received says: "Wireworm damage in Ventura County this year has" been more widespread and severe than any of the oldest inhabitants can recollect." Other reports indicate that at least three-fourths of the bean fields show wireworm damage'' in- varying1 degrees* •'

-273-

• . JAPANESE BEETLE' (Popillia japonica -Newm. )

Connecticut. W. E. Britton (July 23): ■ More prevalent than ever before in the southern half of Fairfield and Hew Haven Counties, and in the Hartford and Now London areas* The heaviest infestations seem to he in Bridgeport, ' Hartford,- New Haven, and Ridgefield. The earliest emergence recordod was on June 22. Two lots of adults from. Now Haven have been received for identification.

Rhode Island. A, E. Stene (Jtily 23): The Japanese beetle 'is 'showing increase in present infested localities but so far as known no new localities have been discovered in which infestations are sufficiently heavy for neople generally to discover them.

New York. E. P. Felt (July 23): P. japonica is more abundant than heretofore in southeastern New York. In some localities- in- festations approach outbreak proportions.

New Jersey. T. N. Dobbins (June): In the vicinity of Moore stown the first adult beetle above ground was found on June lU, whereas in 1936 the corresponding date was Jtinc J, Adults increased slowly, probably as a result of the comparatively cool, cloudy weather, but by the end of the month they were becoming abundant locally, espe- cially in southwestern New Jersey, where feeding damage became evident by the close of the month. The normal, evenly distributed rainfall of May and June provided ample soil moisture so that in most sections the soil is in excellent condition for rapid emerg- ence and oviposition with the advent of normal July weather.

Delaware. L. A. Stearns (July 23): Severe injury throughout the northern portion of New Castle County. Apparently about the peak in the cycle of infestation by this insect.

Maryland. E. N. Cory (July 26): Many reports and requests for informa- tion being received from many parts of the State.

ASIATIC GARDEN BEETLE (Autoserica castanea Arrow)

Connecticut. W. E. Britton (July 23): This insect prevalent in certain

localities and caused damage. Seventy-five adults were received

from a garden in Stojnford. It is attacking various flowering and vegetable plants.

"WHITE- FRINGED 73EEVIL (Naupactus leucoloma Boh.)

Florida. J. R. Watson (July 23): N. leucoloma apparently reached the

peak of its emergence in Walton and Okaloosa Counties between July 10 and 15. It was estimated that there were close to 50^,000 beetles per acre in someaof these fields., The beetles are actively laying eggs. One of the most striking observations was that they are breeding parthenogenetically. A. N. Tissot was the first to observe that no moles were to be found.

-27^-

Elorida and Alabama. H. C. Young (July l): Known infested area, 35 square miles — 20 square miles in Walton and 13 in Okaloosa Counties, Fla. t and 2 in Covington County, Ala. One- third of area is in cultivated crops and remainder in cutover and woodland range. Host plants of the larvae are corn, cotton, velvetbeans, sugarcane, peanuts, sweet-potatoes, parsley, cocklebur, carpetgrass, paspalum, cabbage, collard, amaranthus, and apple, trees. Adults attack cotton, corn, and peanuts.

Alabama. .J. M. Robinson (July lU): Adults are emerging near Lockhart.

Mississippi. C. Lyle (August 10): Light infestation discovered at 'Laurel.

A WEEVIL (Calomycterus setarius Roelofs)

Connecticut. M. P. Zappe (July 22): Adults plentiful in Stratford, about

as many as last year. In old infestations at Sharon not so many adults as last year, but adults plentiful at two new localities in the southern part of town. Plants attacked are clover, sweet clover, Ampelopsis, and Helenium. Some injury to garden peas in one place.

GREEN JUNE BEETLE (Cotinis nitida L. )

Virginia. A. M. Woodside (July 2l): Green June beetles became very numerous in codling moth bait pails at Staunton on July 6 and have contimied so, although their numbers are now decreasing.

C. R. Willey (July 10) : These beetles were swarming about and feeding on Chinese elms U miles east of Amelia and 5 miles southwest of Amelia they were as bad on several medium-sized black oaks, feeding on the tender new growth ^ mile away. On the same farm they were swarming about several apple trees and several Wild Goose plums. -

GRAPE COLASPIS (Col asp is brunnoa F. )

Virginia. C. R. Willey (July 13 to 17): This beetle quite numerous on-

crapemyrtle and Deutzia in nurseries around Norfolk. Doing consider- able damage to some by chewing tender tips of new growth.

Georgia. T. L. Bissell (July 29): Adults feeding on the inside of bracts surrounding cotton squares and bolls. Little damage apparent. •

Arkansas. D. Isely (July 2U) : Has caused some local injury by feeding on the bracts of the cotton squares and on foliage in the northeastern part of. the State.

Alabama. J. M. Robinson (July lU) : Actively feeding on cotton and soybeans in Madison and Limestone Counties, adjoining Tennessee. Some years • ago this beetle was observed in the Tennessee Valley, affecting the stands of cotton, corn, and soybeans, the larva

-275-

having fed on the roots of these plants. We also found that the larva feeds on the roots of lespedeza, which is grown in a large way as a hay crop in the Tennessee Valley. Apparently these- insects are spreading into the cotton at this time.

CUTWORMS (Noctuidae)

Illinois and Wisconsin. N. F. Howard (July l): Full-grown larvae of

Prodenia ornithogalli Guen. were found in pea fields in Illinois and Wisconsin, hut were not numerous enough to cause noticeable damage •

Nebraska. D. B. Whelan (July 22): Moths of the cotton cutworm (P. ornithogalli) have recently been very numerous at lights at Lincoln, reaching their peak about July 15-20, and indicating a possible outbreak later in the season.

Mississippi. C. Lyle (July 23): D. W. Grimes collected specimens of the yellow-striped army worm (P. ornithogalli) at Durant on July 13» It was attacking cotton at Puckctt on July 8.

Wisconsin. C. L. Fluke (July 20): Lycophotia margaritosa saucia Hbn.

is in very destructive numbers in southern Wisconsin, particularly in Iowa, Grant, Lafayette, Green, Rock, Dane, Dodge, Columbia, Pond du lac, and Manitowoc Counties. They emerged first in the hayfields and as soon as the hay was cut moved into adjoining grain, corn, or potatoes. Have also caused trouble in the barns around the milking machinery, many dying there and emitting con- siderable odor.

Minnesota. A. G. Ruggles (July 19): L. margaritosa saucia is very abundant. Reports coming from all over the State.

Nebraska. M. H. Swenk (July 22): A very severe outbreak of the varie- gated cutworm occurred from June 8 to July 10. It did considerable damage to alfalfa, corn, potatoes, many garden crops, flowers, meadows, shrubs, and trees. These complaints were received from many parts of the State.

South Dakota. H. C. Soverin (July 3): Cutworms of several species,

including the pale western cutworm (Porosagrotis orthogonia Morr. ) , have done an immense amount of damage in South Dakota this year. In fact, this has been the most destructive cutworm year we ever had in this State.

SUGAR BEET WEBWORM (Loxostege sticticalis L.)

North Dakota. F. G. Butcher (July 19): Sugar beet webwerns have caused considerable alarm in various places, being particularly numerous in a weedy flax field in Grand Forks County and in potato, wheat, and barley fields in Foster County.

-276-

Idaho. C. lakeland. (July 2l): Local outbreaks of the beet webworm in Latah and Benewah Counties, in northern Idaho. Lambsquarters has been almost completely defoliated and larvae have attacked peas, doing very heavy damage in small areas. The attack is much worse along the margins of the fields, but some injury occurs throughout the fields, owing to the presence of lambsquarters, on which the spring brood evidently oviposited. The second generation of moths began appearing July 13.

Colorado and Utah. 0. A. Hills (July 6): Outbreaks' this year are un- usually numerous, particularly in the Grand Valley of Colorado, whore this insect rarely becomes of economic importance. It has been necessary this year to spray about 15 percent of the sugar beets in western Colorado and eastern Utah.

GARDEN WEBWORM (Loxostege similalis Guen.)

Missouri. L. Haseman (July 2*0 : During the first half of the month

the garden webworm did much damage to corn, alfalfa, and garden' crops in_ central Missouri.

Nebraska. D. B. Whelan (July 22): There have also been large flights of the moths of the garden webworm at the light trap. Trouble with this "oest later in the season was indicated again on July 16-18.

Texas. F. L. Thomas (July 23); L. similalis is causing more injury than usual in central Texas in cotton and alfalfa in the Bell, Hunt, and Limestone Counties from the middle to the last pf June.

WHITE-LINED SPHINX ( Sphinx lineata F. )

Michigan. R. Hut son (July 22): The white-lined sphinx moth is common about Saint Johns and Lansing.

-Wisconsin. C. L. Fluke (July 20): Extremely numerous in hay, potato, and alfalfa fields. Feeding mostly on purslane but unconfirmed reports on potatoes and sudan grass. Reporte'd from .nearly every county in south-central Wisconsin, running northeast from Lafayette County to Brown.

Minnesota. A. G. Ruggles (July 19): Larvae sent in from two-thirds of the counties of the State. So numerous that, farmers are alarmed, but little damage thus far. Feeding mostly on purslane, then fire- weed, then leafy spurge. ' Has been found feeding on lettuce and carrots and did some damage in a field of potatoes.

South Dakota. H. C. Severin (July 23): The white-lined sphinx has

appeared in enormous numbers over the entire State. Consider- able damage -is being done to garden and field crops, as well as to shade trees.

Tennessee. L. B. Scott (July 22): Being taken in traps in large numbers in Montgomery County. This species is at least twice as numerous as in a normal year. No reports of damage by larvae have been received.

Idaho. C. lakeland (July 21): Larvae are very abundant in several' localities of this State and are occasioning many inquiries. Reports have been recei ved from Fremont and Teton Counties of eastern Idaho and from Latah, Nez Perce, .and Benewah Countins in northern Idaho. Larvae are feeding almost exclusively on dock and what is locally called tar-weed, only attacking other crops after these weeds are defoliated, at which time the larvae are practically mature; therefore little damage to economic crops is caused,

EIGHT-SPOTTED FORESTER (Alypia octomaculata F. )

South Dakota. H. C. Severin (July 23): The eight-spotted forester has been more abundant than usual and has done considerable damage to grape, woodbine, and related plants.

Nebraska. M. H. Swenk (July 22): Numerous reports of the presence of larvae on wild or cultivated grapes and woodbine were received from June 12 to July 15 from Sheridan, Lincoln, Howard, Nuckolls, Wayne, Lancaster, and Do\iglas Counties.

CEREAL AND FORAGS-CROP INSECTS

T7HEAT AND OTHER SMALL GRAINS

ARMYWORM ( Cirphis unipuncta Haw. )

Connecticut. R. B. Friend (July 20): Six acres of oats in Newingtor.

and about 5 acres of grass in on orchard in Farmington destroyed. Caterpillars about fully grown. Also reported from Guilford, where between 5 and 6 acres of grass and clover in an orchard and 1 acre of sweet corn were infested. The sweet corn was severly damaged. This insect has also been reported as feeding on grass in an orchard in Hampton.

New York. N. Y. State Coll. Agr. News Letter (July 6) : Armyworms showed up in Niagara County this week, eating all the clover cover crop in one orchard. (July 26): Armyworms have come to the front during the past week in Chautauqua County. They are pretty well scattered over the entire county, but are serious only in a few places on the Lake Erie plain. The armyworms are heavily parasitized by braconids.

-27&-

R. W. Leiby (July lpj): Two local outbreaks on sudan grass and alfalfa appeared from July 13 to 15 in Suffolk County.

Pennsylvania. H, P. Antoine (July 27): Infesting oats and corn; 50 acres 50 percent damaged in Newton Township, Lackawanna County. Attack is localized.

Virginia. D. W. Jones (July 27): In Onley a few local cornfields are

practically ruined at this time "by army worms of the second genera- tion. They are now about j/h inch long and have not yet begun to migrate.

E. J. Udine (June 10): Damage heavy. In an infestation at Tiraberville the barley stems wore eaten nff just below the heads, allowing the heads to drop to the ground. Damage was greatest in the low parts of the field.

Ohio. T. H. Parks (July 22): A flight of armyworm moths has been in progress for the last U weeks. They have been caught in large numbers in the codling moth bait pans, and at an electrocutor trap light. The numbers caught have decreased greatly during 'the 'last few days and the flight seems to be about over. Injury to ripening cherries by the moths was received from Lorain, Sandusky, and Franklin Counties. No complaints of outbreaks have been reported to us during July. The chief injury caused by the June outbreak was to young grass seeded in the wheatfields. This was destroyed in many fields of southwestern Ohio.

Illinois. W, P. Plint (July 21): The armyworm outbreak, which occurred during the last month has about run its course. There is still some trouble in the extreme northern counties, where the army\7orm larvae are now about half grown. In this section of the State the worms are less numerous than they were in central and northern Illinois.

Michigan. R. Hutson (July 22): There is an outbreak of armyworms in the Saginaw Valley, in the east-central part of the State,

Wisconsin. C. L. Fluke (July 20): Outbreaks were just becoming apparent

on July 17. Reports from Dane, D'dge, Columbia, Washington, and Fond du Lac Counties are more numerous than usual.

Minnesota. A. G-. Ruggles (July 19): Armyworm reports beginning to come in from Clay County and some southern counties.

Iowa. C. J. Drake (July lH): The second generation of armyworms is doing some damage in oatfields. The infestation seems to be quite wide- spread in the northern half of the State.

North Dakota. J. A. Munro (July 20): Armyworms were present in most of the oatfields examined in the Harwood, Argusville, Durbin, and Kindred

-279- -

vicinities. The infestations were spotted over Cass County. In one case where the field of oats was being cut— Durbin — the worms were moving out into an adjoining field of wheat. Reports, most of which were accompanied by specimens, indicate that the distribution of the worms is much more widespread than was the case in 1927. Reports have been received from points in Richland, Cass; Traill, and- Sargent Counties. I noticed only a few tachinid flies in areas where the worms were prevalent.

Oklahoma. F. A. Ponton (July 20): The Calosoma beetle which was so prevalent following the amy worn outbreak lias been identified by the National Museum as Calosoma lugubre Lee.

Montana. H. B. Mills (July 22): There is now a rather critical outbreak -of the army worm in Richland County.

Utah. G. F. Knowlton (July 5): Armyworms are damaging wheat in one field near Roosevelt.

HESSIAN FLY (Phytophaga destructor Say)

Ohio. J. S. Hnuser (July 1937) : T^-G hessian fly is less abundant in Ohio than it has been at any time since 1929* The average infestation of the 3^ counties visited during the course of the annual wheatfield survey was found to be U,U. percent. In 193& the state-wide average was 12. h percent. Clermont County, in the southwestern part of the State, was more heavily infested than any other. The average of the 10 fields examined was 15 percent. The lowest infestation in the State (2 percent) was found in Tuscarawas County. In 193& Butler County ranked highest in the State, with an infestation of 50 percent, but this year the infestation there was only 5*7 percent.

Minnesota. A. G. Ruggles (July 19): Hessian fly is scarce. One report re- ceived from Winona County.

Missouri. L. Haseman (July 2*+): Stubble infestation in northeastern and south- eastern Missouri is running as high as from 50 to 70 percent withtMsome cases, as much as three-fourths of the flaxseeds showing- parasitization in southeastern Missouri, according to recent observations by G. D. Jones.

WHEAT STEM MAGGOT (Meromyza amcricana Fitch)

Ohio. E. W. Mendenhall (July 2): The wheat straw maggots e.ro quite bad in

wheatfields in western Counties — Miami, Champaign, Auglaize, and others.

Kansas. H. R, Bryson (July 27) ■ The wheat stem maggot is more abundant this

year than it has been for several years, according to observations by R.

H. Painter,

CORN CORN EAR WORM (Heliothis obsoleta, F. ) Minnesota. A. G. Sandahl (July 20): Corn ear worm is moderately abundant in

UBRARY STATE PLANT BOARD

-280-

Lake Crystal, Blue Earth County,

Iowa. E. V. Walter (July l4): Eggs and larvae are present on 84 percent of the ears in one field of early corn in Van Buren County. Counts made in sweet corn from July 12 to 15 showed 12 percent of the ears "infested at Charles City and l6 percent, at Belmond, in northern Iowa; 40 percent infested at Polk City, in central Iowa; and -80 percent infested at Chariton, in southern Iowa, Larvae, probably first brood in northern Iowa, were near- ly full grown. In- southern -Iowa mature larvae had left the ears, and eggs presumably of the second generation constituted most of the infesta- tion, ,. '•• :

Missouri, L, Haseman (July 24) : Corn ear worm has been very s'erlbus In the tassels of field corn and in early sweet corn ears. Worse for this season of the year than usual,

Nebraska. M. H. Swenk (July 22): Our only complaint of the corn ear Worm so far this season was received on July 3 from Pawnee County, where it was working in popcorn.

Kansas. H. R. Bryson (July 23): This pest is still causing considerable in- jury to corn, particularly sweet corn.

STALK BORER (Papaipema nebris nitela Guen, )

Indiana. J. J. Davis (July 26): The common stalk borer was reported damaging corn at Noblesville and Elwood the first few days of July. At Elkhart it was reported damaging lilies on June 30* *n all' cases the specimens submitted were rather small, being hardly more than one-fourth grown..

Minnesota. A, G-. Ruggles (July 19): The stalk borer is moderately abundant. A number of reports of injury to potatoes and corn.

Tennessee, G. M. Bentley (July 21): Reported as attacking cotton and corn grown in proximity of weed patches. The report has just come from Ripley, Lauderdale County, where there is a considerable infestation in weedy cotton.

EUROPEAN CORN BORER (Pyrausta nubilalis Hbn.)

Vermont. H, L. Bailey (July 26): Many adults about old cornfields* in Essex, . Chittenden County, northwestern Vermont, the last i,7eek in June and the first week in July, Scattering of moths noted in the couniy on July 21.

Massachusetts. A. I. Bourne (July 23): The European corn borer is at least

normally abundant throughout the State, : Here in the Connecticut Valley . .;■•■•• it is proving to be much more conspiciious generally than it was last year. We are beginning t^ note a considerable amount of damage from corn borer in fields of potatoes. This particular type of damage is most conspicuous in southern Hampden County, in fields just above the Connecticut State lino. Early maturing sweet corn in many fields shows from 80 to 90 percent of the stalks infested and the ears are heavily infested.

-281-

Cormecticut. N. Turner (July 2l): Infesting sweet corn, the corn "borer has been unusually destructive locally and is much earlier than in 1936. First-generation moths are present.

M. P. Zappe (July 22): Very abundant in southern New Haven County. Many larvae have reached pupal stage. Attacking corn.

Indiana. J. J. Davis (July 26): According to reports from Auburn, emergence of corn borer moths was the latest of any season on record in Indiana. The first male adults were taken on June 23. nearly 2 weeks later than in 1936. The first female was taken June 25 and the first eggs June 28. Cool nights delayed oviposition; otherwise weather conditions have been ideal for borer increase,

A CORNSTALK BORER (Diatraea sp. )

Texas. 0. D. Deputy (July l): Green corn offered for sale in the markets at

Brownsville seems to run about 25 percent damaged. The stem end of the ear is most frequently attacked.

CHINCH BUG (Blissus leucopterus Say)

Ohio. T. H. Parks (July 22): Excessive rains through June and July have completely eliminated the chinch bug as a problem for this season.

Indiana. J. J. Davis (July 26): The cool, wet weather has apparently checked the development of chinch bugs. In Porter County, in the extreme north end of the State, reports of conspicuous abundance were received on July 10. From Morgan County, in central Indiana, where chinch bugs have not been conspicuous for many years, came the report on July 15 that sorgo was being badly attacked in spots. The bugs submitted were from second instar to nearly mature. It is believed that these are the immediate progeny of overwintering bugs. Reports from Greene County (between Vincennes and Terre Haute) on July 20 indicate some trouble from the first brood, these being sufficiently numerous to indicate probable trouble from the next brood of bugs. 'The outbreaks are scattered and slow in showing up, making control applications difficult.

Nebraska. M. H. Swenk (July 22): Chinch bugs did slight damage to corn in Nemaha County during the second week in July, but were not injurious elsewhere in the State. No migrations were reported from elsewhere than Nemaha County.

Oklahoma. F. A. Fenton (July 20): Damage has been reported from Vinita, Craig County; Bixby, Tulsa County; and Haskell, Muskogee County, in north- eastern Oklahoma.

C. F. Stiles (July 22): Chinch bugs are present in larger numbers in Choctaw County, southeastern Oklahoma, than they have ever been, ac- cording to reports from old settlers. Corn in some fields has been seriously damaged.

-.282-

A CERCOPID (Lepyronia quadrangular i s Say)

New York. R. W. Leiby (July 13): This angulate frog hopper migrated to a field of corn from a freshly cut meadow and completely destroyed a portion of the field. In another field, where corn was just up, a third of a 15-acre field was destroyed. The injury took place during a period of very hot weather in Fonda.

SOUTHERN CORN ROOT WORM (Diabrotica duodecimpunctata P. )

Ohio, T. H. Parks (July 22):. A serious outbreak of the larvae was reported in sweet corn during July. Reports came from Hamilton and Hocking Counties, southern Ohio.

Indiana. J. J. Davis (July 26): The southern corn root worm has "been re- ceived as damaging corn from the northern half of the State, the first reports coming from Frankfort and Remington, on July 8 and 12, re- spectively. At Crown Point, corn following this spring's planting of sugar beets was damaged on July lU. At Conner sville 90 percent of commercial sweet corn acreage in one field was destroyed on July 19. Considerable damage also reported from Winamac, Pulaski County, on July 21.

Missouri. L. Haseman (July 2H): Serious throughout central Missouri. Beetles emerging in great numbers.

CORN ROOT WORM (Diabrotica longicornis Say) . •

Kansas. H. R. Bryson (July l6): Reported causing injury to corn at Garnett.

CORN SILK BEETLES (Luperodes sppO

Mississippi, C. Lyle (July 23) J The corn silk beetle was found attacking roses at Kilmichael on June 25, and cotton at Laurel, Ripley, and Decatur during the first week in July. It was also reported on cotton and corn at Lake on July 7 a-T-d on cotton at Aberdeen on July 20.

Louisiana. B. A. Osterberger and M. B. Christian (July): Pound injuring corn in Franklin garish. About 80 percent of the silks completely destroyed; very few grains of corn on ears. Also found injuring cotton.

CORN FLEA BEETLE (Chaetocnema y.ptilicaria Melsh.)

Indiana. E. V. Walter (July 20): The corn flea beetle is much more numerous at this time of the year than it has been for the last 2 years at Lafayette.

ALFALFA

ALFALFA WEEVIL (Hyper a postica G-yll.)

Utah. J. C. Hamlin (June): Injury by the alfalfa weevil was light this season,

-283-

except in Millard County, Utah, and in Douglas County, Nevada, where 50 percent of the fields were severely damaged. Scouting revealed the weevil. in five counties not heretofore known to he infested; namely, Boston, Campbell, Sheridan, and Johnson in Wyoming, and Custer in South Dakota.

California, A. E. Michelbacher (July 19) : In the San Joaquin Valley there was

a marked increase in the alfalfa weevil population. On July U the average number of larvae collected per 100 sweeps of an insect net ran as high as 785» This increase is probably the result of a partial second genera- tion. In the Pleasanton and San Francisco Bay areas the larval popula- tion has remained small. On July 12 the average number of larvae collect- ed to 100 sweeps in the most heavily infested field in the San Francisco Bay area was llU. In other fields larvae and adults have been difficult to find, Parasitization by Bathyplectes curculionis Thos. has dropped very rapidly. On July h it was less than 1 percent in the San Joaquin Valley, while in the cooler regions it was about 12 percent.

POTATO LEAFHOPPER (Empoasco fabae Harr. )

Virginia. F. W. Poos (July 20): More abundant on alfalfa this season than at any time during the last 8 years. All cuttings are severely yellowed and injured. The yellowing began to show up as early as June 8, although this insect first appeared the night of May 5» only 2 days earlier than in some, other years.

Indiana. J. J. Davis (July 26): Alfalfa yellows, caused by the potato leaf- hopper, has been unusually prevalent since July 15 throughout a large portion of the southern half of the State and extending north, at least as far as Lafayette. Also less conspicuous to the northern border of the State.

. . A CLOVER SEED CHALCID (Bruchophagus sp.)

Oklahoma. C. F. Stiles (July 22): The clover seed chalcid is quite numerous in the alfalfa-seed-producing area of Washita County.

THREE-CORNERED ALFALFA HOPPER (StictQcephala festina Say)

Louisiana. L. 0. Ellisor (July): Is very abundant in fields of alfalfa in the southern part of Louisiana, In some fields at least 75 percent of the alfalfa plants are girdled.

COWPEAS

COWPEA CURCULIO (Chalcodermus aeneus Boh. )

Georgia. T. L. Bisscll (July 23): The curculio is very destructive to cowpeas this year, unst'ung pods being hard to find. First-generation adults appeared in cages on July 18.

Alabama. J. M. Robinson (July 2l): Active on cowpeas in central and southern

Alabama.

-2gH-

VETCH .

VETCH BRUCHID (Bruchas brachial is Fahraeus)

Pennsylvania. C. C. Hill (July 7): Heavy damage in Arendtsville "by this pest.

SUGARCANE

SUGARCANE BORER (Diatraea sac char al is F. )

Louisiana. A. L. Dugas (July): Infestation of the sugarcane moth "borer is generally light throughout the sugarcane area. A number of localized areas present a rather hea\ry infestation. The very abrupt decline in egg deposition in the last 2 weeks has been accompanied by a heavy natural parasitization of Trichogramma. An unidentified larval parasite was collected on July 26.

FRUIT INSECTS

...,-■ SHOT-HOLE BORER (Scolytus rugulosus Ratz.)

Maryland. E. IT, Cory (July f): Found on Japanese weeping cherry at Pikesville.

Ohio. T. H. Parks (July 22): More than the usual number of complaints have been received about this insect in peach, plum, and cherry,

Indiana. J. J. Davis (July 26): Destructive to cherry at Hammond on July 5 an<^ at Noblesville on July 10.

SAN JOSE SCALE (Aspidiotus pemiciosus Comst.)

New York. R. E. Horsey (July): A couple of branches on glossy buckthorn at Rochester were found to be infested with scale. Young moving scales were noted here on July 20.

Georgia. 0. I. Snapp (July 13): Infestation has increased rapidly in a number of peach orchards at Port Valley, central Georgia..

COMMON RED SPIDER (Tetranychus telarius L.)

Idaho. R. 1. Haegele (July 23): Within the last week or 10 days extremely

severe infestations of the two-spotted mite have appeared on apples and prunes that were free of mites 2 weeks ago. Prune orchards sprayed 2 weeks ago for European red mite are now badly infested with the two- spotted mite.

APPLE

CODLING MOTH (Carpocapsa pomonella L.)

Massachusetts* A. I. Bourne (July 23): There are indications that the codling moth is more abundant this year than for the last few seasons.

-285-

New York. D. W. Hamilton (July 2k) : First-brood adults began to emerge between July 12 and 15, and daily bait-trap captures are still increasing. Band captures were, still increasing on July 19» Peak flight* of first-brood moths will probably occur about August 2. Most of the first-brood en- trances occurred during the second and third weeks of June; consequently there should not be as much late August and early September injury as there was in 193&.

New Jersey. E. Kostal (July 12): First-generation infestation seems to be the heaviest. since 1933»

Delaware. L, A. Stearns (July 23) J Injury at close of first-brood attack less than at any time since 1929» First first-brood moths emerged on July 2; peak flights on July lU and 17« First second-brood eggs deposited on July 5 and first second-brood larvae emerged on July 9»

Virginia. A, M. Woodside (July 21): Adtilts.of the first summer brood began to emerge at Staunton on July 5» Emergence has apparently passed its peak. Infestation is generally fairly light.

Georgia. C. H. Alden (July 21): Well-sprayed orchards at Cornelia have only a light infestation, even tho the weather has been dry and favorable for codling moth development.

Ohio. T. H, Parks (July 22): The bait-pan catch of moths has been rather low since June 23» No definite peak of second-brood moths has yet appeared, nor is one expected. The frequent summer rains have apparently done much to prevent many second-brood entrances,

Indiana. J. J, Davis (July 26): The first full-grown larvae left apples at Orleans, in south-central Indiana, on June l6, 2 days earlier than in 1936 and 3 days earlier than in 1935* However, cool, wot weather slowed up activity and the development of the second-brood worms is several days later than normal.

L. F. Steiner (July 22): Activity of first-brood adults as indicated by bait-trap captures, reached its peak in southwestern Indiana between July lh p.nd 17, or approximately 1 week later than in 193&» Although first-brood adults are only about half as abundant as the spring brood, the present population is nearly as great as that of the first brood in 1936, which was far above normal. Weather conditions have been much less favorable for -second-brood establishment this season. In one moderately well-sprayed orchard first-brood worms averaged more than 25 per 100 apples, with additional sting injuries of 80 per 100.

Illinois. W. P. Flint (July 2l): Second-brood codling moth was. somewhat delayed because of the cool weather during the first part of July. The hatch of worms is now heavy over the entire southern half of the State.

Michigan. R. Hutson (July 22): The first adults of the second brood arc be- ginning to appear at Buchanan, Monroo, Lapeer, Vandalia, and Allegan.

-286-

Minnesota. A. G-. Ruggles (July ig) : Codling moth is moderately abundant,

Missouri. L. Haseman (July 2^): Second- brood worms emerging all over the State but they are being effectively controlled. .

H, Baker (July 30): The first first-brood' moth was caught June 30 at Saint Joseph, in the northwestern part of the State. The first big catch was on July 15 and the peak catch to date was on July 2U. Damage by second-brood worms is at its peak at present and is heavier than was( anticipated. Abundance about .average.

Nebraska, W. TUT. Darlington (July): Damage by the codling moth was identified from as far west as Sheridan County in apples sent in the first week of July. The survival of overwintering larvae at Lincoln was 67 percent, as indicated by larvae gathered under bands and placed in racks in the fall, of 1936» a11^ 57 percent of the overwintering larvae of the spring brood had pupated by May 12,- when the initial 1937 observations were made. Pupation continued to June 2U, although bulk pupation had oc- curred by May 29» The first moth emerged on. May 22; peak of emergence, May 29; the last moth of this brood emerged on July 3? 60 percent of the spring-brood moths had emerged ^oy May 29. In bait-trap catches at Agricultural College orchard the first and last moths were taken on May 19 and June 25» respectively, with the peak of catches on May 25 # 28, and 29. Egg laying by moths of the spring brood began May 27 and continued through July 3» the largest number of eggs laid on any 1 day being on May 30, The earliest date on which first-brood larvae were found under bands was June 19» the number collected increasing daily to July 6. From July 7 to July 20 the number of larvae collected under bands gradually decreased} a sufficient number was collected on the latter date to indicate continuance of first-brood larvae for several weeks. Pupation of first-brood larvae began June 20 and reached its peak on July 6 and 10. First— brood moths began to emerge on Jxily 3» Peaks of emergence occurred on July 10, 12, 18, 20. Oviposition by first-brood moths was first observed on July 11 and the greatest number of eggs were laid on July l6. First-brood moths have been taken in bait traps since July 11, with the largest single catch on July l6.

YELLOW-l'JECKED APPLE WORM (Datana ministra Drury)

Missouri. L. Haseman (July 2*+): Larvae were maturing on July 20 and are far more abundant in central Missouri than for years.

LEAFH0PPERS (Cicadellidae)

Indiana. J. J. Davis (July 26): Leafhoppers were reported as serious on apple at Valparaiso on June 23 and observations show them to be common and destructive throughout the State.

Massachusetts. A. I. Bourne (July 23): The white apple leafhopper ( Typhi ocyba pomaria McAtee) is most commonly encountered. This year our attention has been called to an unusual abundance of the green potato leafhopper

-287-

(Empoasca fabae Harr. ) and where it is abundant it has occurred at least 2 weeks later than the white apple leafhepper; therefore, its control offered further complications.

Connecticut. P. Garman (July 2l): Potato leafhepper nore abundant on apples than for the last 10 years in. Hartford, New Haven County.

W. E. Britton (July 21): Specimens of Empoasca fabae Harr. on apple have been received from Norfolk and Cannondale.

APPLE MAGGOT (Rhagoletis poraonella Walsh)

Maine. F. H. Lathrop (July 19): The first fly of the season emerged in a cage at Monmouth, Kennebec County, On June 2H. Emergence nearing the peak on July 19.

Massachusetts. A. I. Bourne (July 23): Apple maggot emerging normally and seems to be normally abundant.

Connecticut. P. Garman (July 2l): Plies began to emerge this year much earlier than usual in our cages and have beer, observed in fair numbers in certain orchards. . ■

New York. N. Y. St. Coll. Agr. News Letter (July 6): Apple maggot flics are emerging steadily in the Hudson Valley from cages ojierated by entomolo- gists of the Poughkeepsie staff. In general, it might be said that emergence records and weather conditions indicate a favorable season for . the development of apple maggot.

New Jersey. E. Kostal (July 12): Flies scarce and emergence late. First flies noted on June 25. Larval infestation in early apples light,

FLATHEADED APPLE TREE BORER (Chrysobothris femorata 01 iO

Indiana. J. J. Davis (July 26): The flatheaded apple tree borer was reported to be killing maple trees at Frankfort on June 19 and at Greentown on June 22.

Missouri. L. Haseman (July 2^): Luring the month the adult beetles have con- tinued to be unusually abundant, with some evidence of tree infestation by the larvae. Some larvae practically full grown on July 2^.

Kansas. H. R. Bryson (July 27): The flatheaded apple tree borer appeared from June 20 to July 23» Because of the drought of the last four or five seasons, trees have become weakened and this insect has caused and is still causing considerable damage to shade and fruit trees, as well as to some shrubs. Reports of injury have been received of this pest in- juring walnut trees at Pittsburg and shade trees at Topeka, Arnold, Olathe, Kansas City, and Leavenworth.

Oklahoma. F. A. Fenton (July 20): The flatheaded apple tree borer continues to be possibly the most destructive tree borer in Oklahoma. Reports of borer damage have been received from Claremore, Roff, Chickasha, Roose-

-28g~

velt,. and Prague.

PACIFIC FLATHEADED BORER (Chrysobnthris mali Horn)

Arizona. C. D. Lebert (July 22): Quite a number of shrubs in local yards at Phoenix have been severly injured or killed by this borer. Common among the host plants are Pyracantha, rose, sycamore, willow, and poplar. Infestations seem more numerous this season than usual.

APPLE SEED CHALCID (Syntomaspis druparum Boh.)

Maine. P. H. Lathrop (July 19) ' The first adult emerged in cage at Monmouth, Kennebec County, on June l6. Emergence reached a. peak on 'June 2H.

X LEAF MIIIEH . (Crnix geminatella Pack.)

Kansas and Missouri. H. Baker (July 30): This insect, which is usually pre- sent in smo.ll numbers and of minor importance, is unusually abundant in northeastern Kansas and northwestern Missouri.

PEACH

PLUM CURCULIO (Conotrachelus nenuphar Hbst.)

Maine. P. H. Lathrop (July 19) : Larvae began leaving dropped apples at Mon- mouth, Kennebec County, during the week ended July 17»

New York, N. Y. St. Coll. Agr. News Letter (July 6): In Monroe County, western New York, the plum curculio has caused almost a total loss of some prune crops.

Delaware. L. A. Stearns (July 23): The peak of first-brood adults, as de- termined by jarring at Bridgeville, Sussex County, was on July 8. In- jury will be light.

Virginia. A. M. Woodside (July 2l): Some adults were collected in May at Staunton; still alive in the insectary but feed very little and no eggs have been found for over 2 weeks. All of the beetles. from drops have emerged, but none found to contain eggs and no eggs have "been found in the cages. Beetles feed greedily but do not mate.

Georgia. 0. I. Snapp (July 20): At Port Valley the second-generation qqq deposition began on July 6, just before the Elberta peaches began to ripen; therefore that variety was subjected to a second-brood attack this year. All other varieties of peaches escaped a second brood of larvae. Forty-nine percent of the first-generation females had started to deposit second-generation eggs by July 20. The infestation is lighter than average.

Missouri. L. Hascman (July 2U) : This pest is seemingly greatly delayed in its breeding. Some varieties of plums at Columbia show considerable numbers of larvae from half to full grown.

ORIENTAL FRUIT MOTH (Grapnel Una nolesta Busck)

Connecticut. P. Gar man (July 2l) : In Hartford and New Haven Counties second- generation larvae are abundant in many orchards.

New York. N. Y. St. Coll. Agr. New Letter (July 19): In Orleans and Niagara Counties terminal injury of the Oriental Fruit Moth is becoming more conspicuous.

Delaware. L. A. Stearns (July 23)1 Injury by second brood moderately severe. Brood. about mature. Parasitization approximately average.

Virginia. W. J. Schoene (July 21) : Infested peach twigs, which became num°rous about 2 weeks ago, are dropping off in numbers. Considerable fruit in- festation is appearing in some orchards in Staunton.

Georgia. C. H. Alden (July 20): Fruit scored at harvest showed about 2.0 percent infestation, as compared with 0. 5 percent in 193^. This insect is in- creasing slightly over the upper middle and northern parts of the Peach Belt, at'Thoraaston and Monticello.

GRAPE

GRAPE BERRY MOTH (Polychrosis viteana Clem.)

Virginia. C. R. Willey (July): Much more numerous than usual, judging from my own and my neighbors1 grapes and by requests for identification and control.

GRAPE LSAFHOPPER (Erythroneura comes Say)

New York. N. Y. St. Coll. Agr. New Letter (July 19): In Niagara County the

grape leaf hopper hatch appears about complete with older nymphs develop- ing wing pads. In a few vineyards these pests will cause considerable damage. Also reported from Ulster, Dutchess and Columbia Counties.

-290-

Delaware. L. A. Stearns (July 23): Population so light that the usual spray in early. July was omitted.

doing any damage. The first new weevils emerged in the insectary at Tifton early in the week. (July 2U): Upland cotton in southern Georgia has set a large crop of "bolls, which are fairly well matured and past danger. Part of the Sea Island cotton failed to set early "bolls, there- fore most of it has a scarcity of well-grown "bolls and is likely to suffer,

Florida., K. H. Smith (July 2*4) : In Alachua County, northern Florida, square, infestation in Sea Island fields under observation showed an average of 6,9 percent for the week ending July 3 an& o*1 July 2H .an average of 27«5 percent.

Tallulah, in Madison Parish (Delta section) have been unfavorable for the multiplication of boll weevils. First generation weevils havo been emerging for a week or 10 days but, owing to unfavorable conditions, the infestation has not increased as expected. (July 2^): In some fields cotton is fast reaching maturity. In field plots the infestation ranged from 5. to. 32 percent, averaging 6 percent during the week,

C. 0, Eddy (July): Boll weevil has increased its activities during the last. half of the month, owing to rains.

Texas. K. P. Ewing (July 3): Infestation in Calhoun County increased during the week to an average of 23»12 percent, as compared to 10.7 percent the preceding week. In the Lavaca River bottom at Edna there was an average of 70*28 percent punctured squares. (July 2*+): Average in- festation 70.^+9 percent. The maturity of the cotton combined with the high weevil infestation in all of this area, particularly in Calhoun and Jackson Counties, has caused the cotton to practically stop blooming in many fields. There was a noticeable migration into small cotton this week.

Prog. Rpt. Tex. Agr. Expt. ;Sta. (July 3)' In general, boll weevils are causing far more damage in the coastal prairie section north of Corpus Christi than is realized. All cotton fields in the Lavaca River bottoms of Jackson County are being severely damaged where no control measures have been used. (July 10): The boll weevil infestation is increasing in southern and south-central Texas. (July 17): ' Average infestation records from eight counties in t he State, ranging from Van Zandt and Smith in northern Texas to.

Texas. K. P. Ewing (July 10): Daring the last 2 weeks there has been a marked decrease in the flea hopper infestation in Calhoun County. (July 2H): In the young cotton flea hopper infestation continues sufficiently high to cause nearly all squares to be blasted.

R, W, Moreland (July 17): In Brazos and Burleson Counties the in- festations have been very light in upland cotton fields. On July 10 some dusting was being done in the bottom fields.

Tex. Agr. Expt, Sta. Prog. Rpt, (July 17): Plea hoppers are in small numbers and causing -practically no damage, except in northern and northwestern Texas. J. R. Quinby states that this insect is responsible for the loss of from three to five' small squares each on 90 percent of the plants of May-planted cotton in Hardeman County. In Dickens County the average infestation in 11 fields is 100 flea hoppers to 100 buds, with a maximum of 222. flea hoppers. (July 2U): Plea hoppers have de- creased in northern Texas but have increased on young cotton in southern Texas.

Florida. K. H. Smith and J. T. Roy (July 6): Pupae of the leaf worm were

collected on Sea Island cotton today near Alachua and Mcintosh. As these fields are some U-5 miles distant, this indicates that the leaf worm may be scattered over the northeastern part of the State. (July 19) : In a UO-acre field near Alachua loaf worms were found in sufficient numbers to be ragging the cotton in spots. As many as 25 worms were found on a

-311-

s ingle plant i ranging from tiny threadlike worms a day or so old to pupae.

Florida, T7. E. Conn (July 12): Light infestations in 2 acres of cultivated cotton at Miami and some larvae now entering into pupal stage.

K. P. Ewing (July 2*0: The infestation in Calhoun County in the Gulf coast section is very spotted. _

Tex. Agr. Expt. Sta. Prog. Hpt. (July 2*0: Leaf worms have been reported in west-central Texas. Their appearance near San Angel o, in Tom Green County, is from 2 to 3 weeks earlier than usual and may in- dicate an earlier invasion of northwestern Texas. T7 rms collected in south-central Texas have been found to be heavily parasitized for this time of year. (July 31)' Have caused comparatively little injury to date. They were found last week in Reeves Crunty. The recent hot, dry weather in central Texas tended to cause the newly matured moths to fly a greater distance, even though uninfested cotton is near.

Arizona. 7T, A. Stevenson (July 2*+): At Fresnal, Pima County, a very light infestation was discovered on July 23. The first infestation in 193& was found on August 12.

BOLLWORM (Heliothis obsoleta F. )

TARNISHED PLANT BUG (Lygus pratensis L. )

Tennessee. D. M. Simpson (July 8): In 1935 we practically had a crop failure, owing to damage from tarnished plant "bugs. We have a heavy "infestation of those insects again around Knoxville and a large percentage of the plants are practically devoid of squares. The insects are abundant in nearby fields of soybeans and lespedeza, also in weeds and grass. On a recent visit to western Tennessee several farms were visited in Pay- ette County near Somerville. On every farm damage similar to that at Knoxville was noted and tarnished plant bugs were found in the fields.

Maine. J. V. Schaffner, Jr. (July 16): N. Urafton reports defoliation of hundreds of acres of woodland in Kennenec, Sagadahoc, and Lincoln Counties. The infestation is the heaviest on record for these three counties. Defoliation was spotty and local in the northern part of York, southern Oxford, Androscoggin, and Cumberland Counties,

Portland Press Herald (June 29) : Officials of the State depart- ment of agriculture report the worst gyptyy moth scourge ever to sweep southwestern and central Maine. Occurrence of the moths in devastat- ing numbers is reported as far as Kennehec and Knox Counties, and in less serioue intensity eastward along the Oastal counties to .Washing- ton County.

Massachusetts. J. V. Schaffner, Jr. (July 6): Thousands of acres of wood- land in the eastern part of the State are completely defoliated. The defoliation within 25 or J>0 miles of Boston is more extensive than it has "been for many years.

A. I. Bourne (July 23): The defoliation this year was much more general and widespread than in any recent year. There are "beginning to he many centers of rather serious defoliation just west of the Connecticut River. Throughout central and eastern Massachusetts are similar large areas of very serious foliage strippings; however, in the Cape district, from Buzzard's Bay to Province tov:n, conditions are apparently "better than for several years.

Rhode Island. A. E. Stene (July 23): Prohably the most outstanding note

regarding insect prevalence during the past month is the increase in gypsy moth infestation. We have had large areas heavily infested with this insect in the past, "but there were a greater numher of * places involved during the past season and the aggregate area where defoliation has taken place is quite large.

Pennsylvania. A. P. Burgess (July 17): The interest of. a former W.P.A. worker resulted in the discovery of a larval infestation near the Coolbaugh-Paradise Township line in Monroe County. This man, now employed "by the Delaware, Lackawanna, & Western Railroad Company, observed an egg cluster Of the gypsy moth while working along the railroad right-of-way and reported to the field supervisor in charge of that district. Numerous larvae have since "been discovered in a rather restricted area. Intensive treatments will "bo applied in an effort to eradicate the infestation.

BROWN- TAIL MOTH (Nygraia phaeorrhoea Donov. )

Reports received from the supervisory personnel in Vermont indicate that much damage is "being done in certain sections. Peeding is also noticeable in limited, areas in sections of Massachusetts and northwestern Connecticut.

Maine. N. Trafton (July 15) ! Many acres of woodland were severely defoliated in Cumberland, Oxford, and York Counties.

Vermont. J. V. Schaffner, Jr. (July 23): In Addison, Bennington, Orange,

Rutland, Windham, and Windsor Counties infestation was heavy. Thousands of acres of maple sugar orchards and mixed hardwood forests were from 50 to 75 percent defoliated. The humid weather in the spring favored epidemics of disease and large numbers of the caterpillars while in the fifth and sixth instars succumbed to Mwiltn, thus reducing the infesta- tion so that few trees were completely defoliated.

H. N. Bean (June 23): In Randolph, Royalton, and vicinities small areas of naple and "birch were defoliated. Large areas of defoliation in town.

Minnesota. P. W. Porbes (June 20): Tent caterpillars reported very abundant at Bemidji, Beltrami County.
