THE INSECT PEST SURVEY BULLETIN A periodical review of entomological conditions throughout the United States issued on the first of each month from March to December, inclusive. Volume 10 October 1, 1930 Number 8 BUREAU OF ENTOMOLOGY UNITED STATES DEPARTMENT OF AGRICULTURE AND THE STATE ENTOMOLOGICAL AGENCIES COOPERATING A" ~ INSECT PEST SURVEY BULLET IUl Vol. 10 October 1. 1930 No. 8 OUTSTA2TDING ENTO.CLOGICAL FEATUTJS IN THE Uiil11. STATES FOCR SEPTEMBPER, 1930 Grasshoppers still continue to attract considerable attention through- out the gr-"-.ter part of the country. In mny places the d-'.nage h-s even increased over th-'t done in August. Sev--r-1l species of cutvorms Pre reported from the Rocky Mountain and the .West Coast Sta.tes. The'fall arm--orm became generally prevalent over the Middle Atl-ntic States during the month, ,.attracting unusual attention by attacking lavMns in toTv-ns and cities. Damage by .7hite grubs is becoming very evident, as the season advances, in the Centr-al St-"tes from Indiana 7,esttiard to Nebraska, and southward to Mis souri. In this number of the Survey Bulletin is a suanrtry of the survey work on the Hessian fly for the Middle Atlantic, East Central, and Jest Central States. The Hessian fly situation as a whole is not, alarming. From con- ditions in southern and west-central Illinois and parts of .Jiissouri and Indiana, hoa'ever, there is reason to believe th'At unless checked by adverse weather conditions this insect will be decidedly more troublesome next year in this region than it has been in several years. The cotton leaf worm made one of its very extensive north.. rd flights about the middle of September. The moths were observed in large numbers in southern M.issouri on September 14. in southern Illinois on September 15, in the District of Columbia on September 23, in southern Michigan and ITE York City on September 24, and in Boston, Mass., on September 25. Codling moth eggs continued hatching during the first two reeks in September in Illinois, Indiana, *nd Yentuck-y, and moths were still emerging in centr-l Ohio during the third week of the month. In the L-ke Region of Ohio late brood of the oriental fruit moth -352- seriously dram-.ged late varieties of perches harvested after the middle of September. To the southward, in Indian,-, Illinois, and ,entucky, infestation se,;med to be much less serious, particularly in apple, ,nd only moderate abundance is reported over the lIe'- England and South Atl-ntic regions. A green stink bug, Chlorochro. sayi Stal, is recorded from the St-.te of Nebraska for the first time. It was found injuring potatoes in Eimb-ll County. The imported cabbage worm is very seriously infesting cabbages in Illinois, Iowa, and Miinnesota, and rather serious infestations by the cabbage webworm are reported from North Carolina, Alabama, and ;'iszissip2i. The cabbage looper is appe-aring in very considerable numbers over the same region and also northward into Virginia. The beet leafhopper is abundant in northern Utah and considerable damage is resulting from the infestation. The fall webworm is occurring very abundantly throughout the eastern States from Vermont southward to ilorida ;nd Alabama. The birch leaf skeletonizer is occurring in a heavy outbreak in northern Maine and the upper and lower peninsulas of Michigan. The elm leaf beetle is so prevalent in Connecticut that unsprayed trees are brown in many parts of the St'te, and it is more prevalent at Raleigh, N. C., than it has been during the past fifteen years. In the drought-affected States mosquitoes are unusually prevalent, perhaps because small streams, having been dried to puddles, afford ex- cellent breeding places. OUTSTA.lDIIIG L1ITOIOLOGICAL FEATURES I:: CAIIADA FOR AUGUST AND SFT-,3ER, 19cO A correction: The outstanding entomological features in Canr-d, in the August 1 number of the Insect Pest Survey bulletin, referred to July, 1930 instead of AuCust,1930, as published on page 259. Reports during the past two months indicate a definite up-rd trend in gra-sshopper populations extending from southern Quebec, thr"u i Ontario and the Prairie Provinces, to British Columbia. With the exception of the C'iilcotin ranges, British Coluibi', -io.vever, grasshoppers, in general, - .ere nowhere sufficiently nuj,1erous to cause serious crop d- mge. The pale western cut-.'orm continued in severe outbreak form in Saskatchewn, but the outbreaks of the bertha armyworm which developed in 1929, in "-,itoba and Alberta, completely subsided, and there w"7 no . -353- recurrence of damage this season.* -In British Columbia, cut'.orms, generally speaking, were scarcer and less injurious than for many years .ert. A r-ther heavy, infestation, of the .-herit stem saWfly occurred in south, western 1,anitoba and locally in eastern Alberta, and serious damage by this species was anticipated in sections of Saskatchewan. .1hite grubs have been on the increaLse for several years in sections of southern Quebec, -nd a heavy flight of the beetles is forecast in 1931. Severe damage to field and garden crops was reported from southeastern Ontario. In British Columbi- this pest 7 as about normal. The diamond-back moth was prevalent in Saskatchewan and Alberta and -.'as extraordinarily abundant and destructive in sections of British Columbia. The European corn borer infestation in the M.aritime Provinces continues very local and light. Hornworms ,ere more abundant on tomato and tobacco in southwestern Ontario than they have been during the past few years. Thelccucnber beetle was unusually destructive in ITe-i Brunswick. srrpe A species of grain aphid caused much damage to late sown Oats in sections of eastern Saskatchewan and locally in western :,anitoba. Aphids of many species "ere unusually abundant in British Columbia this season, but the woolly apple aphid -7-s notably scarce. Reports indicate that in most ports of the Dominion fruit aphids were of comparatively minor importance in 1930, The aple aphid, however, was noted in outbreak numbers in sections of [e'- Brunswick. The codling moth was reported as unusually injurious in Ontario and the Maritime Provinces. An increase also was noted from southern Vr-ncouv.cr Island. Else7hcre in British Columbia the codling moth was notably scarce. Fruit injury by the oriental peach moth in southern Ontario is light. Red spider mites were conspicuously injurious to small fruits in south- western Ontario and southern Manitoba. Grape and apple leofhoppers increased in abundance in southern Ontario. A fruit blight, possibly carried by thrips, caused material damage to raspberries and loganberrics in coastal sections of 3ritish Columbia. During the past summer in British Columbia, a u:cd decrease was noted in the abundance of several species of injurious fruit insects including the oyster-shell scale, lesser apple rorm, pear slug, peach twig borer, curratt fruit fly,and the imported current worm, The European beech bark louse h.s caused the doe-th of many treCs on the mainl-.nd of Yova Scotia, -354- The black headed budworm continued to effect material d.-r=,ie on C:1F: Breton Island,.. Nova Scotia, and. also wrs rt.Fortedipi outbreak form- on the British Columbla coast. Widespread and he.a*vy inf-stationIs of. thw birchx leaf. skeletonizer occurred in the Maritime Provinces, and southern Quebec. ;.. The fall webworm is present in conspicuous .bundance throughout eastern Canada, but has shown a, decided dcrc*ase ,.in the Lower Fraser Valley, British Columbia. .. - The maple leaf-cutter occurred in greatly reduced nhumb:-rs, compared with previous years, in Ontario and southern The' hemlock looper outbreak which developed on th f"i.';trsheds of the Trinity and Pentecote Rivers on the .north shore of thi St. L.-.rcnce, Quebec, in 1928-29, subsided entirely in 1930. .;, A survey of the satin moth in the Maritime Provinces revealed several sm!nll infestations, of the insect in Westmoreland and Albert Counties, Noe- Brunswick, in addition to the 'one previously reported'dt Moncton. In iTov, Scotia, outbreaks were located'at'various points between Anr..polis and Yarmouth. In British Columbia, this species has continued to spread on Vancouver Island and in the ,Lower Fras er V-.lley..:.; -. In general, bark beetles have" shown adecided'increase over large areas in British Columbia, rnd have- been unusu'uly destructive this sEzmcr. -5 5- G E I ; R AL FEEDERS GRASS-HOPPERS (U`crididae) South Carolinp illinois 'ichigan Einnesota Uorth Dakota South Dakota Iow a Missouri :Tebrz ska Colorado SI-er:,an (2epttzber 19): Several species of grasshooOers especially J cl no3-us f1rfr-rubrn' DeG., are very abundant in Salud.a County.

F. Knowlton (September 21); Grasshoppers are moderately to very abundant. They seem to be becoming less abundant than they wore last month. G. G. Schweis (September 22): Grasshoppers are very abundant in -'estern ievada. Considerable damage has been done to the second crop of alfalfa. C. D. Lebert (September 25): Grasshoppers are troublesome only in the northern part of the State at the present time. They were eating truck near Prescott, rather voraciously about the 15th of Se-ptember. D. C. 1Jote ( uCuzt): Grasshoppers are very abundant on field crops in Lane County. CUT,'OR'.S (Noctuidae) J. A. Munro (September 19): Cutworm injury to flax fields extended through the first week in July at Te-7he, Pembina County, according to a report received from a 'rm.er of that vicinity. He states that many fields of flax, which had been resoown during June on account of previous cutworm injury, had been seriously injured a second time. He estimated that cutworms had caused 50 per cent injury to flax fields in his part of the country. The cutworms were identified as -uxoa ochrogaster Guen. H. E. Jaques (Septerber 25): Ten counties report marked fall activity of cutworms. C. P. Gillette (September 19): Lycophotia margaritosp saucia Hbn. is very abundant and injurious to celery in the Denver area. It is also doing considerable injury to potato vines in parts of the San Luis Valley. G. G. Schweis (August 19): Species of Prodenia have been reported from a wide area, including many counties in Nevada and eastern California, where they have been reported as doing damage to alfalfa, potatoes, grapes, and other crops. C. K. Fisher (August 27): The yellow-striped armyworm (PIdenia -raeficia Grote) has been doing considerable doaxkge to baby lima and blackeye beans in the vicinity of Modesto. .;orms first started in lIfqlfa. FALL AZMYiVORN (Lnphygm,. {gipgrda S. & A.) L. A. Ste:.rns (September 15): The fall army-orm w.s seriously abundant ip certain localities about Felton and Ccmden, August 20, -357- Maryland District of Columbia Virginia North Carolina Georgia E. N. Gory (September 22): Lanhyma fruginerda is present in injurious numbers on lawns in Baltimore, on bent grass in Baltimore County, on barley and wheat for forage in Harford County, on rye in Montgomery County, and on alfalfa and barley in Kent County. U. S. D. A. Press Service (By Dr. '. H. Larrimer) (Sept'ember 20): The long, dry summer has prevented the growth of succulent grass in pasture lands and as a result hundreds of lawns are now being overrun with these caterpillars, not only in the District of Columbia but throughout nearby States. Vhat is perhaps more serious economically, this caterpillar is destroying fall-sown -.heat -.nd other small grains which have been planted for early fall pasture, because the long dry season prevented the usual growth of grass in the pasture lands. G. E. Gould (September 24): The fall ariyworm has been exceedingly'abundant this year. The present brood of larvae commenced to do noticeable damage early in September and since then reports of damage to many crops have come in from all parts of eastern Virginia. On the Eastern Shore damage was observed to Sudan grass and sorghum. Around Norfolk the larvae have caused damage to rape, kale, broccoli, collards, turnip salad, savoy cabbage, rutabagas, grass, and garden peas. In the northern part of Virginia a field was observed where this insect had destroyed 30 acres of German clover and had done some damage in 50 acres more. i7. J. Schoene (September 17): Reports of serious injury in several counties in eastern and central Virginia have been received. It seems that the insect is generally distributed. F. N. Darling (September 15): There is an infestation of the armyworm in Northampton County, where much damage is being done, Evening Star, Washington, D. C. (September 26): The fall armyworm, after campaigning in nearly every other section of the State, has crossed Chesapeake Bay and attacked the crops on the Mastern Shore. G. T. French, State Entomologist, said yesterday the worm has appeared in large numbers in both Accomac and :Torthampton Counties, and County Agent 7. E. Strong of Accomac has written the State Department of Agriculture that "the armyworm is destroying hundreds of acres of our fall hay crops such as rye, -heot, and crimson clover." C. H. Brannon (September 20): This species is continuing widespread damage over the State. H. S. Adair (September 25): Larvae were numerous in Albany and other localities in southern Georgia during July S-358- Florida Alabama Mississippi Pennsylvania West Virginia Iowa Uevada Indiana and were oQbserved fe'.dinrg on grasses and various field crops. Moths emerg.2d the latter part of August from material placed in the insectary and were observed quite numerous in the field during the latter part of August and the first of September. J. R. Watson (September 24): The fall armyorm did con- siderable damage about Raiford.-in September. J. M. Robinson (September 19): The fall army-ormn started its injurious work, but a fungus destroyed a large percentage of the larvae. R. W. Harned and assistants (September): The southern grass worm has continued to attract considerable attention on corn, cotton, soybeans, and grf-.sses of various kinds during September. Clay Lyle (September 8): Many fields of hay in Cktibbeha and surrounding counties have been ruined by the southern grass wormduring the past week. This seems to be the worst outbreak of the worms since 1912. ',.here fields of young corn are located near maadows.that are being cut, the worms are likely to-move into the corn and destroy it quickly. ;IREP0R;.:S (Elateridae) C. A. Thomas (September 22): Potatoes in several fields in Bucks- County were badly injured by lrxvae of Pheletes agonus Say, during September. At least 20 per cent of the tubers were bored into by these wireworms and the gro-wers estimated that they reduced the value of such potatoes by at least 50 per cent. L. :". Peairs (September 20): Wireworms are injuring potatoes in Wood County. H. E. Jaques (September 25): ;7ire7cr-,s are moderately abundant in several counties in northeastern Iowa, G. G. Schweis (September 22): ;.ireworms are modEr.ately abundant. Doing considerable damage to potatoes. WHITE GRUBS (Phyllopha,& spp.) J. J. Davis (September 22): Numerous reports of abundance and destructiveness of white grubs have been received from northern Indiana and along the 7est side, north of abcut the center. The reports indicate a continued southward spread of this destructive brood of grubs. The majority of inquiries referred to injury to corn, although some referred to serious damage to timothy, blue grazs, the turf of golf courses, and ,trawberries and general crops. The drought conditions intensified injury in some cases. Illinois Missouri Nebraska Pennsylvania W. P. Flint (September 15): White-grub injury is becoming more apparent with the advance of the season. Dcrnz.e is showing at the present time in many areas where little injury was noted up to the middle of August. This damage is confined to the northern half of the State. H. E. Jaques (September 25): Most of the counties in the eastern half of the State show moderate to heavy d.:rage to corn, potatoes, and pastures. The insects are only moderately abundant in the northwestern white-grub area. L. Haseman (September 24): White grubs are moderately abundant. Emergence of adult beetles continued later than usual this summer. M. H. Swenk (August 15-September 1).: During the latter part of August the number of complaints of injury by white grubs increased greatly. These all related to the part of the State lying north of the Platte River and east of Holt and Buffalo Counties. The injury was to hay meadows, lawns cornfields following grass, and strawberry bods. CEREAL AND FORAGE-CROP INSECTS WHEAT HESSIA, FLY (Phytophaga destructor Say) C. C. Hill (August 18): The result of the summer survey for the Hessian fly indicates the following percentages of infestation in the several counties of this State, as follows: County Infestation (Per cent, .

H. Parks (September 27): Early sown and volunteer heat in central and northern Ohio was remarkably free from Hessian- fly eggs during late September. We have not yet visited the heaviest infested area in our State (Butler Ccunty) to determine the presence of eggs on the heat there. It is apparent that the hot, dry weather gave the fly a serious setback. Ohio County w361- ... P. Flint (August).: ..Thu annual survey which was carried On by the Tatural History Survey cnd the Bureau of -ntomology has been conrpleted. This year the survey covered 57 counties and the infestation is about the same as last year uith slight increase of the fly in parts of the State. Dry weather has reduced volunteer -"7heat and considerably retarded fly development.

J. R. Horton (September): In Missouri the aver:.ge in- festations ran below 25 per cent of the stems infested. Only in occasional fields were infestations high encuih to affect the yield. In Kansas infestations 7-_re quite generally low, averaging but 10 per cent of the stems in the eastern portion and 14 per cent in the western portion of the State. Yields -7ere not measur-bly affected by the fly except in Hia-L-.tha in the extreme northc,-st portion and Colby in the extreme northwest portion of the State. On the other hand Nebraska infestations were in general. exceptionally high, averaging 41 per cent of the stems infested.

CORN CHINCH BUG (Blissus le-.copterus Say) J. J. Davis (September 22): The chinch bug is moderately abundant in the extreme northeastern corner of the State. W. P.Flint (September 15): Chinch bugs are reported from several counties in the south and west-centr-l pcrts of the State. The increase in -'bujndance of chinch bui: this ye-r has been extremely rapid. They have prob-bly increased in abundance more rapidly this year than at any time during the last twenty-five years. Unless checked by -dv-rse 7eather conditions we would expect commercial injury in sc.'cral counties next season. H. E. Jaques (September 25): Chinch bugs vere moderately abundant in Lee County, Iowa, but otherwise practically absent in the State. I found them very -%und-nt in Henry County, Missouri, early in September. L. HWseman (September 24): The chinch bug is moderately to very abundant; very abundant on some farms in centrral belt across State. CORN EAR i;OBM (Heliothis obsolet: Fab.) H. L. Bailey (Septembecr 23): The corn ear -worm is moderately abundant at Moritpelier; plentiful in a small cornfield in the city, A. E. Stene (September 18): The corn ear worm is very abundant. T. J. Headlee (September 9): The corn ear -orm is moderately abundant. E. N. Cory (September 22): The corn ear worm is very abundant, L. :'1. Peairs (September 20): The corn ear rorm is very -bund- t in Yonongolia County, their "ork especi-lly noticeable in vie" of the short crop. North Carolina South Carolina Florida Ohio Illinois Michigan !..'i nnesOta Kentucky Iowa Mis souri Arkansas ,.:ississippi W. A. Thomas (September 11): The larvae are now extremely abundant on late tomatoes and beans at Chadbourn. Some plants were observed today where every tomato fruit had been injured, many of the young fruit buds destroyed, and some stems eaten off. The foliage was also injured by the larvae feeding on leaf and petiole. P. K. Harrison (September 4): Late corn is quite heavily infested. J. R. ;Yatson (September 24): The corn ear worm is feeding extensively on the seeds of beggar-7ecd, and mining the ground cherry, Physalis spp. E. W. Mendenhall (September 23): The corn ear worm is very bad on sweet corn, in most parts of the State. The ravages of this pest are quite marked, destroying a large percentage of the kernels of corn and making the ears unma rke table. W. P. Flint (September 15): This insect increased very rapidly during the last few days of August and the early part of September. Counts made in sweet corn fields on the east side of the State showed from 44 to 57 per cent of the ears infested. Eggs ore very common on Indian mallow. J. H. Bigger (September 15): The corn err worm is moderately abundant. Thirty-one per cent infestation in west-central. Illinois but moderate dan-age done. R. H. Pettit (September): The corn ear worm is scarce in general. A. G. Ruggles and assistants (September): The corn ear worm is generally scarce throughout the State. A. Price (September 24): The corn ear worm was present in 80 out of 100 ears of corn at Springfield. H. E. Jaques (September 25): The corn ear worm is moderately abundant in the western half of the State. Winneshiek, Benton, Mahas':a, and Jefferson Counties also report moderate abundance. It is very abundant in Henry County, Missouri, in field corn. L. Haseman (September 24): The corn ear worm is very abundant, in southern Missouri attacking soybean pods. D. Isely (September 24): Corn ear worms are very abundant. The crops attached are corn, soybeans, and cotton. R. 7'. Harned (September 22): Only two complaints have been received during the past month. -3.66- STALK BORER (Pnpaipem. nebris nitela Juen.) Indiana M1ichigan Iowa Nebraska J. J. Davis (September 22): The stalk borer hrs continued to be commonly referred to in correspondence. Th6 first pupa '7as received September 2 and all received since that date (the last, September 17) were pupae. All reports were of infestation in corn, excepting one received from Otterbein which was in golden. glow. R. H. Pettit (September): The stalk borer is very -.buniant in general. H. E. Jaques (September 25).: The stalk borer is moderately abundant in Crawford, Harrison, and Madison Counties. M. H. Swonk -(August 15-September 1): A few reports of cornstalks bored by the common stalk borer received during the last half of August. After August 20 most of the specimens sent were pupae rather than caterpillars. Other reports received add Thurston, Colfax, and Merrick Counties to the list given in my previous report.

Haseman (September 24): There has been an epidemic of close-wing moths, consisting mostly of some three species, during the last two weeks of September through, central Missouri. They are attracted in swarms to light on warm nights. LESSER CORN STALK BORER (7lnsmopalpus lignossllus Zell.) J. R. Watson (September 24): The lesser corn stalk borer has been destroying chufas on the State Farm nt Raiford. . R. W. Harned (September 22): This insect has attracted considerable attention during the Ir-st month in various districts of the State. Specimens collected from copee, bean, and lima bean plants have been received from Holmes, Marshall, Tippah, Forrest, and Pike Counties. . A CER-:.3YCID (Prionus fissicornis Hald.) M. H.

Gillette (September 19): The Colorado root worm is moderately abundant in northern Colorado and very abundant in some cases where corn followed corn. SOYBEA IS VELV-TBE.'_ T CAiTERPILLAR (Anticarsia p-ermatilis Hbn.) W. E. Hinds (August 29): This insect is now quite abundant in the district around ilew Iberia and Jeanerette and ragging of foliage has occurred in some fields. The outbreak is generally some two weeks later than that of 1929 and will be less severe. Moths and larvae occur in some numbers as far north as Baton Rouge, and probably farther than this. The soybean crop is being harvested for hay, or turned under, very generally regardless of worm occurrence, and in the southern section about 80 per cent of the crop is already safe from worm injury. I do not anticipate serious da.ir-g, to the crop except in late-planted beans. C. F. Stiles (September 22): This insect and the corn ear worm (Heliothis obsoleta Fab.) have destroyed the soybean seed crop in most districts of Oklahoma. It first attacks the small beans and later the leaves. ALFAL-JA A'7D CLOVER Wisconsin J. E. Dudley, Jr. (September 24): Owing largely to parasites, predators, and possibly drought, the pea aphid practically disappeared from fields lite in August. Largest array of natural enemies ever observed, Nabis ferus L. being the most prevalent species. During the past 10 days infestation has developed until now from 20 to 50 are secured in 50 sweeps of a net. Accompanying the rise of the aphids, there is a falling off of the number of narLturl-1 enemies taken. PEA APHID (Illinoia pisi Kalt.) -368- Anri z ona Arizona Mississippi (Hemiptera) E. A. McGregor (September 1): Exmin-i-ations of alfalfa fields near Aztec, where .hu crop is being gro-Th for seed, developed the fact that the seed yield is beinG materially reduced through the activities of bugs, of which the follo'.ving .;ere the more common: Lyus.elisus Van D., Ceresa occidentalis Funkh,, Chlorochroa sa.

Wolcott (September 25): This is to report the appearance of large numbers of moths of the cotton caterpillar, on the warm and rainy night of September 24 at B-rnveld. G. Myers (September 24): The cotton leaf worm 7ns observed in great numbers on the buildings and lamp posts in Washington on the morning of September 24. T. H. Parks (September 27): These moths have -ppeared in the Lake Erie peach section and have been puncturing the skin of ripening pe-ches. The injury is not so serious as during some years. S. C. Chandler (September 15): The cotton le-f -.-orm is found v:ry sc-rce in the cottonfields of Pulaskl:i cnd Alexr-nder Counties. .369.- 1ichigan Missouri M4ass achus etts North Carolina Ohio Indiana Illinois J. P. Flint (September 18): There.is report of a heavy flight of the cotton leaf caterpillar in southern Illinois on the night of September 15. R. H. Pettit (September 25): On the 24th of September a specimen of the Alabama moth was sent in from Kalamazoo. This is evidently the first record for Michigan in 1930. L. Haseman (September 24): During August and September cotton fields in the cotton-growing counties of southeastern Missouri were serious damaged by the cotton leaf worm. On September 14 moths were taken in considerable numbers for the first time this year at Columbia in codling-moth bait pans. CODLING ':OTH (Carpocrpsa pomonella L.) A. I. Bourne (September 23): The codling moth is moderately to very abundant. There are a considerable number of late-season stings. The second brood this year was larger than normal. C. H. Brannon (September 3): Damage to apples in the mountains is exceptionally light this season. T. H. Pirks (September 27): This insect is much more serious than usual in our State. LawrEnce County has suffered most and ir. this county a third brood of codling moth larvae developed this year and damaged the fruit since August 20. Moths are still emerging end a sprry program carrying three cover sprays following the calyx application did not prove effective in controlling the insect. Elsewhere in the State the insect is under control but has increased rapidly. J. J. Davis (September 22): The codling moth problem is a serious one in southern Indiana. F. H. Lathrop (Septe.mber 15): In labor-tory studies in- cluding large numbers of codling moths, the emergence of moths declined sharply during the first week in September, showing that the larv-.e are going into winter quarters. This is confirmed by field obs.rv-tions. Nevertheless, considerable numbers of newly hatched larvae are still entering the fruit in the orchards about Vincennes at this date. P. Flint (September 15): Eggs have been hatching during the first two weeks of September. Many apple orchards are showing an unusual amount of damage from very late worms. S. C. Chandler (September 15): There has been a general heavy hatch of codling-m:oth -orms in the orchards of southern Illinois beginning about the 1st of September. Intr,-.nces were especially noticeable by September 7. -1) fA Kentucky Missouri Kansas Arkansas Alabama Nevada *Znshington Oregon Connecticut Delaware W. P. Flint (SepteMiber 18): On 'eptember 2, 3'r. S-.z_-ra ex:-mined a number of bands that had been on apple tr-e-s for ten days in one orchard at Parkersburg. A count revealed 700 larvae and only one pupa, indicating that the worms are going into hibern-.tion. :Ie-7ly hatched larvae were entering the fruit in numbers,. ,. A. Price (September 24): Otserv-tions of the cc-linU. moth at Henderson indicate a decline in emergence of -jaults since September 1. :um:crs of new entrances were observed on apples September 17, indicating that moths are still plentiful in some orchards, R. M1. Jones (SeptembEr 17): '.7ell sprayed orc-'-rds are relatively free of worms in south--estern Missouri. Other orchards show moderate to serious infestations, depending upon thoroughness .and timeliness of sprays. L. Baseman (September 24): late worms are'v-?ry abundant. In' northern Missouri we have had three broods this year -ith the third-brood worms very -,'bund.int. P. M. Gilmer (September 19): There has been rather severe late injury from codling moth in the southern section of the State during the first half of September. P-rt of this is without question due to a small fourth brood. D. Isely (September 24): The codling moth is very -bund-.nt in northwestern Arkinsas. 0. I. Snapp (September 18): The infestation is heavy at Fort Payne. G G. Schweis (September 22): The codling moth is r-rorted on unsprayed fruit, 90 per cent wormy,- E. J. Newcomer (September 22): Owing to cooler -5-ther in June and September, the codling moth infestation is not so severe this season as it wz.s last year. D. C. Mvlote (July): !he first generation of codling moths is about over at Corvallis. Pupae of the second generation appe-ring.,h (August): The codling moth is moderately abundant in hillnmette Valley. Peak of second brood just passed. EAST-TE TENT CATERPILLAR. (::.,-.lacosom- -ric.n- Fab.) W. E. Britton (September 24): The e-stern tent caterpillar is sc-rce. L. A. Stearns (September 15): In New Castle County the tent caterpillar was very -bundint, during late August :nd -371- early September, on practically all shrubs which they commonly infest. Oregon B. G. Thompson (July): The tent caterpillar adults are very abundant in the Willemette Valley. APPLE MAC-GOT (Rhagoletis pomonella Walsh) Ohio T. H. Parks (September 27): The apple maggot was not so serious as last year in northern Ohio where it w-s an economic pest in 1928 and 1929. Emergence of flies in considerable numbers occurred between July 20 and August 9 as determined by R. .i. Dean, who is investig-ting this insect. Two special sprays were advised during this period. In the test orchards the apple maggot seems to be well under control at this writing, owing apparently both to the spraying and to the adverse weather of the season. In a few unsprayed orchards the insect is still serious. No complaints have reached us from localities other than northern Ohio. JAPANTESE BEETLE (Popillia "j,2ponica Newm.) Rhode Island U. S. D. A. Press Service (September 18): During the present summer, surveys have resulted not only in confirming the continuation of the infestation at Providence but in the discovery of additional beetles at ITewport and Westerly. SHOT-HOLE BORER (Scolytus rugulosus Ratz.) Ohio T. H. Parks (September 27): Following the serious drought of midsummer, shot-hole borers are more numerous than usual in peach, cherry, and even apple trees. In Lorain County, the beetles were emerging during August from a brush pile containing prunings of the orchard and were damaging the near-by young apple trees. OYSTER-SiELL SCALE (Lepidosaphes ulmi L.) Minnesota A. G. Ruggles and assistants (September): The oyster- shell scale is quite generally abundant over the southern half of the State. Michigan R. H. Pettit (September): The oyster-shell scale is moderately abundant in general. EUROPEA;I RED :TITE (Paratetranychus pilosus C. & F.) Ohio T. H. Parks (September 27): The European red mite is not a very serious pest in northern Ohio this year. Well sprayed orchards are remarkably free from this mite. ..

Davis (September 22): The peach-tree borer was reported from W7lkertown and Ligonier during the month. S. C.Chandler (September 15): Infesta.tion has evidently not been decreased to any extent by the extremes of heat of the past suMMer. A recent survey in southern Illinois peach sections sho-ed from 50 to 90 per cent of the trees not treated in the past two years to be wormy. By September 3, 84 per cent of the old -orms hnd emerged, 13 per cent were in the pupal stage, and only 3 per cent were still in the larval stage. *.'e are recomra.cnding treatment by SeptEmber 20 in this section, this year, which h is a little earlier than usual. R. H. Pettit (September): Th, peach borer is vcry obund.nt in general. L. Haseman (September 24): The perch borer is moderately abundant. In central Missouri borers are quite abunjar.t. P.

Gould (September 24): Th2 oriental fruit moth is mod er at ely an undant. T. H. Parks (September 27): .hilo the infest.-tion in the Elbcrt' peaches w-s "'*ry light, there h-s developed a late brood which seriously d-'-.d late vwrictics harvested ift.-r the middle of September. This st-t.:..:t ap -lies to counties joining Lke Eric, a.s the crop in -11 other counties was killed by severe winter tcperature. -373- Indiana Kentucky Connct icut Rhode Island Maryl--nd rest Virginic South Carolina Geor- i ; F. H. Lathrop (September ]5): Since August 15, the numbers of oriental fruit moths in peach orchards of Vincennes have steadily declined. Since September 1 it has been difficult to find infested tigs. Infestation does Lot seem to be a serious factor in apple orchards of this section this season. A. price (September 24): Infestation in apples does not soem to be severs in the orchards observed in western Kentucky. However, a cuince tree observed at Henderson bearing about 1 bushel of fruit was heavily infested. F. G.r"an (September 24): The oriental fruit moth is reported in Hartford, ,T&' Haven, end ITe London Counties. tuinces in general, although wormy, show improvement over last year. S "- .tene (September 18): The oriental fruit moth is mod( eratcly abundcaiht. ICory (August 16): The oriental fruit moth is moderately abundant, . L. 1'.. Peairs (Sept-mber DO): The oriental fruit-moth is moderately abiundnt in the eastern panhandle; distinctly less numner:ous than in 1929. A. Lutken (September 19): Th- oriental fruit moth is moderately abundant in the northwestern part of the State. 0. I. Snap (September 17): ,uince fruit in a dwelling is novi ieaviiy infested. This insect causes little damage at Fort Valley in o.c. d.s wler. no fiuit is availa-ble after the harvest of .Iberta peaches. 3. h. -.Lden (September 20): Illinois i4ichigan F-Le oriental fruit moth is scarce. 2. 0. handler (September 15): In the peach sections from Centralia south there have been no ne-; entrances into peach tiigs for a mr:th and scarcely any for two months. Apples in interplanted orchards or close to peach have shown either very light cr no infestation. Parasitism was not over 20 per ceC1t. It is tlought that the extreme L.eat of summer has aided in the reduction "iich has evidently occurred. To date no live larvae can be found cocooned on peach trees. H. Pettit (September): The oriental fruit moth is moderately abundant in the southeastern part of the State; not spreading so r'nidly as expected. ''jiji Georgia :.ichigan Minnesota "'issouri Mississippi Utah -374- J. .... Robinson (Stptember 19): r.e oriental fruit moth is moderately abun-i-nt at Auburn. R. "0.

R. ,i. Harned (September 22): Specimens tentatively identified as larvae of the oriental fruit moth were collected in peaches at Guliport. on September 2 and in pears at :.:errill on the same date. PLUM CU? JULIO (Conotrachelus rnurh r .: st.) 0. I. Snapp (September 11): Only three adults were captured during jarring on three one-half days in a numbc-r of reach orchards at Fort Vallv:. This insect has either left peach orchards for hibernation or Lhe population is very li'set. "e are expecting the adult carry-over to be less than usual. (September 26): Frequent jarrirns in a nxmrier of reach orchards since September 9 have netted a total of only 9 adults. Evidently they left pe ch orchards in this locality unusually early for places of hibernation. R. H. Pettit (September): -.. plumn curculio is very acur.dant in general. A. G. Ruf-les and assistants (September): 2he plum curculio seems to be quite generally scarce over the State, only one County (Lyon) reporting it as very abundant. L. Haserman (September 24): Picked arples show their usual a'hundance of stirgo by the plum curculio. R. Harned and assistants (SepteT'.er): The plum curculio is generally reportc- as scarce throughout the State. PEA P2ArL LEAF ::.;S:':R kl ':(2riop)hves -.Tri F_-st.) F. F.

GBAPE BERRY LOTH (Polychrosis viteana Clem.) T. H. Parks (September 27): Berry-moth injury is present in the grape belt of northern Ohio, but it is not so serious as it was one year ago. Encoura:-ing results were secured by growers who sprayed aE:ainst the first brood during June. PECAJ AN APHID (VMyzocellis fumipennellus jZitch) Georgia Alabama Mississippi Mississippi H. S. Adair (September 25): Th-. black pecan aphid bigan to appear in some pi-can orchards in this locality (Albany) in injurious numbers the latter part of August. Although the infestation is not so extensive as last year it has done considerable darm-age by causing the defoliation of pccan trees. J. M. Robinson (September 19): The black n..cnn aphid is abundant on pecan foliage at Tuscaloosa, Camp Hill, and Auburn. R. ..

The larvae were in their second instar. Several clusters of eggs were examined and it was found that the hatch was 100 per cent. A heavier infestation may be anticipated next year, since the parasitism seems to be low. Tre walnut caterpillar has been practically absent from the pecan orchards in southern Mississippi ever since the heavy infestation in 1927. That year, it will be rcrembtred, wve had three distinct generations. Thr egg parasitism of the third generation averaged 92.3 peor cent. Since that time only an occasional colony has been found. J.
