THE M0E3 IMPORTANT H2C0HDS 102 MAY

By the fourth reek in May egg hatching of tho migratory grasshopper and the two-striped gras sh jpper was almost completed in the upper Great Plains region. Complete destruction of some fields of crops had occurred in the western part of the Dakotas and N« ' ro ska -and in eastern Montana and Wyoming. In the Southern Plains region hatching of the migratory range grasshopper -also was practically complete. East of the Great Plains migratory grasshoppers were advanced to second- stage nymphs during tho third week in tho month in Michigan, central Wisconsin, and in parts of Minnesota and Iowa, and control operations are well under way at sev- eral points. In southern Missouri hatching was well advanced during the second week of Mav, In the Pacific Northwest the migratory grasshopper and tho red-, legged grasshopper were damaging wheat and alfalfa in Idaho during the first week in the month.

The heaviest infestation by the Mormon cricket ever recorded in South Dakota was 'reported during the second week in the month in Walworth County, This insect was also reported as very abundant in southern Tooele County, Utah, and in several counties in Nevada.

Very heavy flights ,of June beetles are reported from the East Central States. Damage to pecans by these insects is reported from the lower Mississippi Valley.

Damage bv wireworns occurred very widely throughout the country. Heavy damage to tomatoes and watermelons by the sugar beet wireworn was reported from the San Joaquin Valley in California.

Very heavy infestation by grubs of Japanese beetle was reported from south- eastern New York and northeastern Maryland.

The' first adults of white-fringed beetle were collected in northern Florida on May 22. Larvae have caused serious damage to crops in limited areas this season. The first adult was taken in the Now Orleans area on May ll. The first

papa of Naupactus sp. was found at Saucier, Miss., on April 29 and at Gulfport Miss., on May 1.

In general, cutworms were subnormal in abundance during the month; however the pale western cutworm appeared in outbreak numbers in western Kansas, where over 10,000 acres of wheat had been destroyed by the first week in May*

In the East Central States there was a general infestation by. hessian fly in northern Indiana and northwestern Ohio.

Spring migration of the chinch hug to snail grain started during the first week in May in Indiana, Illinois, western Missouri, in the three southern tiers of counties in Iowa, and in southeastern Nebraska and north-central Kansas during the third meek in May.

The greenbug ' is generally prevalent throughout the Wheat Belt of Kansas and Oklahoma but little injury has occurred to wheat in Kansas, although oats and barley have been damaged in places. In Oklahoma oats mere a complete failure in Kay County.

A somewhat heavy flight of arnyworm moths was reported from Indiana during the second '■'■reek in May. Some damage by army worm is also reported from south- eastern Missouri and from the .Delta counties of Mississippi*

The wheat brown nite seriously damaged many fields of wheat in western Kansas and southwestern Oklahoma*

Corn ear worm damage is being reported from the South Atlantic .and lower Mississippi Valley States. Pupae in hibernation cages in Illinois failed to pass the ’"inter, but in the St. Louis area of Missouri a 23-percent survival occurred. Bather severe damage to corn was reported from southern California*

Pea aphids began to appear in the Middle Atlantic States early in the month, largely on clover and alfalfa. Severe damage to alfalfa was reported from the northern tier of counties in Indiana, in west— central and south-central Illinois, in southern Michigan end Wisconsin, and in eastern Kansas, Early in the month damage to vetch was recorded from the Willamette Valley of Oregon and some damage to cannery peas was reported from northwestern Oregon,

Tent caterpillars were doing considerable damage to fruit trees in Washington, Oregon, and California*

First adult codling moths of the season were taken on May 3 at Paducah, Ky. , on May 6 in the Vincennes area of Indiana, on May S at Staunton, Va. , end in southern Ohio, in northeastern Kansas and northwestern Missouri on May 10, and on May 19 in central Ohio.

Very heavy populations with considerable damage by the fruit tree leaf roller was reported from western Illinois and eastern Missouri.

Aphids attackin'* apple wore abnormally abundant early in the month in Now England ant the heaviest infestation in the last 10 years occurred during the latter part of the month in the Hudson Hiver Valley, Heavy infestations also reported from western New York. From 10 to JO percent of the apple crop in the Cornelia section of Georgia has been damaged by the rosy apple aphid. Increasing damage by this insect is also reported from the Vincennes area of Indiana. Apple grain aphid is very prevalent in Michigan and Wisconsin, In the latter State it is one of the most severe* outbreaks ever observed,

Inf estation by the plum curculio in the Port Valley section of Georgia is heavier than usual. A fairly heavy drop of peaches is also recorded from the Cornelia section of Georgia, Increased abundance of this insect was reported fron Kentucky, Illinois, Missouri, and Kansas,

Large pecan trees were completely defoliated by a tortricid, Cacoecia in- furaatana Zell., in southwestern Louisiana, This appears to be a new pecan pest.

Potato flea beetles were seriously damaging potato foliage late in the month in New York, Virginia, and Indiana, Heavy infestations ^ere also reported from the Pacific Northwest,

The bean leaf beetle was generally prevalent along the south Atlantic sea- board and in the East Central States.

The pea weevil reached i.ts peak of migration into fields on May S in Oregon and between May 13 and 15 in Washington and Idaho,

The pepper weevil was discovered in two* additional counties in Florida— Charlotte and Hillsboro.

Flights of moths of the beet webworm were observed in the latter half of the month in Utah, Idaho, and Montana.

Large populations of beet leafhopper were reported in the Promontory Point breeding area of Utah, This is the heaviest infestation in the last 4 years for that area.

Heavy populations of overwintered cotton boll weevil were reported from South Carolina, Georgia, and Florida, with somewhat heavier emergence than last year in Louis iana and Texas •

A very unusual outbreak of cankerworns covers a wide belt from Ohio ’across Illinois and Indiana to South Dakota, Nebraska, and Kansas. Elms and unsprayed apples in many places are completely defoliated.

GENERAL FEEDERS GRASSHOPRERS (Acrididae)

General* W. E. Dove (May 26): In the Red River Valley areas of Minnesota and North Dakota, in eastern Montana and Wyoming, and in western North Dakota, South Dakota, and Nebraska, hatch of migratory grasshopper Melanoplus mexi- canus Sauss. and two-striped grasshopper M. bivittatus Say ‘is almost complete^ while hatching of the big yellow grasshopper M. diff erentialis Thos* is just j beginning. Rapid hatch and acceleration of development of young hoppers caused by warm, dry weather. Rapid movement frcan adjacent idle and range lands into cropped areas temporarily reduced by rains occurred during the week. Although average percentage of damage to crops in the northern Great Plains area remains small, some fields have been completely destroyed in parts of Wyoming, eastern Montana, and the western part of North Dakota,

South Dakota, and Nebraska, Heaviest damage where grasshoppers hatched in fields in which the grain had been stubbled in. Hatching of migratory range grasshopper in the Texas Panhandle, Oklahoma, northeastern New Mexico, and eastern Colorado practically complete in some areas and less advanced in other areas of higher altitudes, A very small hatch occurred in the Missis- sippi Valley during the last week,

Iowa. C. J. Drake (May 26): M. bivittatus and M, mexicanus hatching in large numbers, particularly along the Missouri Valley, Control operations in progress for 2 weeks, particularly near the larger cities. Semi-drought con- ditions favorable for young grasshoppers during the hatching poriod,

Missouri, L, Haseman (May 24); Hatch in the north-central part of Missouri de- layed by the weather, and until the middle of May very little hatching had occurred in the northern tier of counties. Heavy hatch in places reported from southern Missouri 2 weeks earlier,

G, D, Jones (May 10) : North-central Missouri is the area most heavily infested with eggs, according to the survey of last fall, which indicated that more than normal egg populations exist in every district where grass- hoppers were abundant last year. Eggs held back in development owing to cool

-115-

woather. Reports indicate hatching of -snail brownish grasshoppers as start- ing last week in southern Missouri, In central Missouri eggs of the yellow grasshoppers about ‘ready to hatch,

Nebraska, M, H. Swank (May 18): Hatching started in such abundance during the

second week in May that distribution of bait was begun in eastern and western Nebraska. Species concerned include chiefly M. bjvittatus and M, nexicanus. with a lesser number of 'M, differential is.

Oklahoma, C. E. Stiles (May 23): Dissosteira longipennis Thos, hatching- in large numbers in Texas and Cimarron Counties, in r the Panhandle, Control operations under way for 2 weeks • M. moxicanus reported as hatching in largo numbers in the northern part of the Panhandle, M. confusus Scudd, generally dis- tributed over the pasture land of the western half of the State, many having reached the adult stage, and damaging some pastures. Hatching of M, differ- ent ialis and M. bivittatus delayed, and nymphs not appearing in damaging numbers yet.

Montana. H. B. Mills (May 20): Practically a 100-percent hatch of eggs of M.

nexicanus occurred from May 3 to 5» sotith of the Missouri River, in an area involving Richland, McCone, Garfield, Petroleum, Rosebud, Treasure, Custer, Prairie, and Dawson Counties. At the same time approximately 20 percent of the eggs had hatched north of the river, the hatch being about a week later than in the southern -area.

California. L. A. Burtch (May 9)! Unusually early hatch and intensity of infesta- tion of the valley hopper Oodaleonotus enigma Scudd. necessitated intensive control measures in Kern County* Infestation heaviest ever seen by the writer Considerable damage done to crops bordering grasslands, extending for a mile or two. Heavy infestations have occurred in the foothills east of Delano, McFar- land, Fanossr, Lerdo, around the Edison orahge groVes and potato fields, and through the Arvin and Coramanche Point sections, where there were the greatest losses and heaviest infestation in the county. Grasslands infested from the edge of the cultivated fiolds' cloar back to the mountains.

of Monocrepidlus spp. done on November 3, 1933, in a field of soybean stubble near Reeky Mount, an averags of 1.2 wireworms per square foot being found by examining a 6- inch depth of soil in 10. square-foot samples taken at random. Thirty-two similar samples "on March 27, after field had remained undisturbed during fall .and winter, showed an average of 1.9 wireworms per square foot. Fields thoroughly plowed to a depth of about 6 inches soon after March 27, and on April 12, from J>2 similar samples, there was found an average of .1,1 .wire- worms per square foot. Soil loose and rather dry on last sampl.ing date and it seems probable that some wireworms were below the 6-inch depth of sampling. Sampling on first date confined to on area of 0.4 acre, while for the second and third dates original area extended to include 1-| acres.

near Santa Ana over 5U percent of the plants were killed, and in a 6-acre planting near Stanton over 3S percent of the stand was replanted. Lima "beans planted early in May also damaged extensively. In parts of a 60-acre plant- ing near Santa Ana every seed examined was infested with from 1 to 9 larvae, and an average of 5 larvae obtained per foot of row. Damage in the 6CUacre planting of melons near Downey, Los Angeles County, continues. Between April l4 and May 18 the number of plants in 86 hills was reduced from 3^ to 109*

B, E . Campbell (May l): Many watermelon fields in southern Eresno County, central California, being damaged by L, canus Lee. In a typical 20-acre field the infestation was scattered, except in one corner where over 2 acres were al- most completely denuded of plants. Counts on 5 plants showed from l6 to 4g wireworms attacking a single plant, averaging 26 per plant. Eield had been replanted 4 times, 4 acres being abandoned and planted to kafircorn.

CEREAL AND FORAGE-CROP INSECTS WHEAT AND OTHER SMALL GRAINS HESSIAN FLY (Phytophaga destructor Say)

General, C. Benton (April 20): Pupation started near La Fayette, Ind, , about April 1. Dissections made on April 19 showed 32 live pupae- present in 100 puparia. No emergence of the flies has. been observed. A spring survey of

-123-

fall-sown wheat was made from March 7 to April 5, covering 4S3 fields _ in SO counties of Indiana; 34 fields in 4 southeastern Illinois counties; 22 fields in 4 northwestern Ohio counties; end l4 fields in 2 south-central counties of .Michigan. In the area covered the 2 sections showing the most general infesta- tion by the fall "brood were northwest-central and northeastern Indiana and adjacent counties in northwestern Ohio. In these areas many fields were heavily infested, with thinned stands of. wheat in poor condition of growth.

Ohio. T, H. Parks (May 22); Ho serious damage to wheat is anticipated in any part of the State.

Indiana. C. Benton ( May 22); Pupae were found throughout April. First fly emer- gence and egg laying occurred on April 26. The crest of fly emergence and egg laying, first week of May, gradually decreased until May 22. First small larvae found on May 3* Mostly half-grown larvae, with a few full-grown, were found "by May 20 in wheat. About 10 percent of overwintered puparia still con- ; tained viable larvae not pupated on May 20.

Kansas. E. T. Jones (May 26); Of 17 wheat fields examined on May 24 in Geary, Dickinson, and Marion Counties infested plants were found in 15. Based on samples of 5^ stems each, average infestation per field was 9*7 percent, rang- ing from 2 to 30 percent, with an average of 3*7 puparia per infested stem.

He injury apparent .

CHIHCH BUG (Blissus leucopterus Say)

South Carolina. W. C, Hetties (May 22); Present but less abundant than formerly

in Chester County. Of 10 small-grain fields surveyed, only 2 had corn planted adjacent, which apparently will help protect the corn.

Indiana, C. Benton (May 23); Si>ring migration to small grains started about May 1 and was practically completed by the middle of May. First mating observed in the field on May 9« By May 20 more than 50 percent found mating. Present numbers found in small-grain fields near La Fayette show a few spots in thin winter wheat and rye, with enough old bugs to produce a light- to-noderate infestation with continuation of present favorable dry-field, conditions. Ho eggs or nymphs were observed,

Illinois. W. P. Flint (May 26); Scattered reports of infestation are coming in. Infested fields widely separated in most areas, the worst infestations occur- ring in heavily pastured rye.

Iowa. C, J, Drake (May 26); Very abundant in the three southern tiers of counties of the State, and here and there, infestation extends into the fourth tier. Weather conditions favorable this spring for the bugs to move from winter quarters to the small-grain fields.

-129-

Oregon. D. C. Mote (May 19): Aphids have continued to increase in peafields in the Willamette Valley since early April, and field peas are injured in. places. In most vetch fields examined the predators have held the aphids in check. More aphids were reported as infesting the cannery peafields oi Umatilla County, than any year since 193^*

M. M. Reeher (May 22); Alates began moving into late fall-sown fields on April 17* On April 20 a few early fall-sown fields of common vetch and Austrian winter field peas were beginning to show some damage to individual tips. By May 15 several early fall-seeded Austrian winter field peas began to show damage in places. Some late fall-sown peas, close to early fall- sown fields also show some injured spots. Common vetch showed some tips killed late in April and early in May. By May 9 most of these fields had been nearly freed of aphids by coccinellid larvae and beetles. Injury not serious on either vetches or field peas but probably increasing in Austrian peas, owing to few natural enemies, fungous disease has remained at a very low point, owing to dry weather. Aphids did not increase as rapidly on Austrian peas, as expected and it is believed that some of this retardation of reproduction may be attributed to the slow growth of the plants during dry weather.

COTTON INSECTS BOLL WEEVIL (Anthonomus grand is Boh.)

South Carolina. E. F. Bondy and C. F. Rainwater (May 27): Very active,

as the week has "been warm in Florence County. A total of 175 weevils removed from cages during the week, as compared to 21 in 193^ . Examinations in the field show generally more weevils in the field for the week than in 1938, as follows: 1 to 43 plants in 1939: and 1 to 128 in 1932. Emergence from cages in May totaled 635 this year, as compared to 2l6 in 1938. Trap— crop and screen— trap catches less than in 1938.

Georgia. P. M. Gilmer and P. A. Glick (May 20): Practically all fields in Dooly, Tift, Cook, Lowndes, Berrien, and Echols Counties show infesta.tion; those planted in the vicinity of old fields quite heavily infested in spots. Fields remote from hibernating quarters or from old cotton have light infestations, averaging from 1 to 3 weevils per 1,000 plants. Average is about 1 to 2 weevils per 500 plants in large fields and from 4 to 6 per 500 in small fields.

Florida. C. S. Rude and L. C. Fife (May 27): Found in several fields in Lake County. Heaviest population noted to date was 17 weevils per 100 plants in a field that was in cotton last season. None found in Lake County in 1938 until about August 1. Many farmers using control measures. Light populations found in each of the fields where experimental plots are located. In treated and un- treated fields examined in Alachua County infestation ranged from 0.5 to 78 percent; in Union County from 0 to 10 percent; in Marion County from 2.6 to 27.8 percent; in Gilchrist County from 0.2 to 12.2 percent; and none found in Putnam County. For the same period last year infestation in these counties ranged from 0 to 14 percent, but cotton was not so far advanced as this season.

Stub cotton in some old fields is heavily infested.

Mississippi. E. W. Dunnam, et al. (May 27): In Washington County 9 weevils found on 150 cotton plants next to woods. Plants in the 6-leaf stage. This area yields weevils earlier, as cottoa la usually seeded earlier than in other .fields 'examined..

Louisiana. R. C. Gaines and assistants (May 27): Weevils removed from hibernation cages in Madison Parish through the week ended May 26 totaled as follows: 311, or 0.89 percent, in 1939; and 310, or 0.89 percent, in 1938. Total taken on field flight screens for the week was 7, as compared with 5 in 1938 and 3 in 1937. Popula- ln fields in Madison Parish has averaged almost the same as in 1-/3°* x94 being found on 4l,000 plants inspected, or 1 per 211 plants.

Texas. F. L. Thomas (May 24): Weevils continue to emerge from hiberna- tion quarters and now exceed average survival; already occurring m noticeable numbers near hibernating quarters.

Texas. H. S. Cavitt (May 27): Total moth emergence somewhat lower than

last week. Only 11 moths from winter-buried and irrigated treatments. A big drop in emergence from the cocoon series, 37 as compared with 62 last week. All but 3 moths emerged from cocoons not disturbed following installation of the larvae. Only 3 moths emerged from thurberia bolls this week, as compared to 15 last week. Apparently emergence from these bolls is practically over.

APHIDS (Aphiidae)

South Carolina. C. E« Rainwater (May 20): Observations this spring in Elorence County have brought out more forcibly than before the fact that Trif idaphis phaseoli Pass, is the most serious root aphid on cotton. Usually a heavy mortality to seedling cotton wherever it occurs. One severely infested field in this vicinity has not more than 25 percent left of the plants that came up.

Arizona. E. R. Tinkham (May 12): Aphis gossypii G-lov. quite abundant on cotton at Continental, Pima County, but heavily parasitized.

COTTON ELEA HOPPER (Psallus seriatus Reut . )

Texas. E. L. Thomas (May 24): With the exception of a few fields in southern Texas, flea hoppers have not done much damage to early planted cotton. There has been a substantial increase in the numbers of young flea hoppers which practically doubled during the last week in Calhoun County. Hatching of overwintered eggs apparently nearly over in southern Texas, but in central Texas considerable numbers have hatched since the rains. In north-

ern and northwestern Texas the hatch is running into fairly large numbers.

C. P. Rainwater (May 20): Thrips appeared suddenly in Florence County. Last week practically none on cotton and this week a heavy infestation. Apparently they came to. cotton.- at the time the first small grain was being harvested.

F. F. Bondy and C. F. Rainwater (May 27) J Some damage to young cotton in Florence County, hut not severe and loss than in 1938.

Mississippi. E. W. Dunnam, et al. (May 27): Of 44 plants examined on May 25 at the experiment station in Washington County, 1 was in- fested with 1 thrips; on May 26 of 75 plants, 25 .were infested with 31 thrips; and of 75 other plants, 19 were infested, with 21 thrips.

Texas. F. L. Thomas (May 6): Some d.amago continuing to cotton in most sections of the State. More abundant than usual in the southern and central parts of Texas since spring began. Early increase, stimulated by the mild winter and the cool, dry weather of the last few weeks, has retarded the growth of cotton so that feeding by thrips has caused leaves to curl and on some plants killed terminal buds.

A CRICKET (Anurogryllus muticus Deg.)

Mississippi. C. Lyle (May 23): Specimens received from Smith County with statement that they were causing injury to corn, cotton, and other plants.

Massachusetts, where there have been outbreaks during the last 3 or 4 years, although egg clusters are still very common in many localities, infestation in general has decreased considerably. Counts made in severo.1 widely separated localities indicate the average egg deposit in 1938 as 50 percent less than in 1937*

Eggs still rather abundant in some localities. Infestation heavy on a great many shade trees in Parre . Hatching was unusually late this year; not general in this area until the first week in May.
