REMEMBER PEARL HARBOR

THE MORE IMPORTANT RECORDS FOR MARCH

Grasshopper hatching started in parts of Arizona in the latter half of February. In the Yuma district some of the nymphs had reached the third instar by the first week in March. In Nevada egg development was practical- ly complete by the end of March.

Mormon crickets were hatching in the second and third weeks in March in Oregon. During the first week in March the coulee cricket was hatching in parts of Oregon.

Cutworms were doing their usual early season damage as far northward as the Norfolk section of Virginia, and an outbreak of t’he army cutworm was developing in Mason Valley of Nevada.

The sugar beet wireworm was seriously attacking carrots and lettuce in California.

The green bug outbreak reported in the last number of the Bulletin has intensified in Oklahoma and Texas, and reports of heavy infestations have also been received from Mississippi and points in Virginia and Georgia.

The chinch bug passed the winter with but normal mortality in Illinois, Kansas, and Oklahoma. In Kansas the population is reported to be the heav- iest thus far recorded in that State.

In the eastern third of Kansas the hessian fly has done considerable damage and much more serious damage is anticipated.

.At Clemson College, S. C., rather large numbers of egg masses of Com- stock’s mealybug survived the winter and the dormant spray operations.

Plum curculio adults were observed in the Fort Valley section of Georgia by the middle of March and by the 19th, considerable numbers were appearing.

Pear thrips began emerging in the Willamette Valley of Oregon the first of the month.

Vegetable weevil was damaging garden crops and tobacco plant beds in Florida and garden crops in Mississippi.

Mole crickets were damaging gardens in southeastern Mississippi.

Considerable damage by the carrot rust fly was reported from several parts of western Oregon.

The recently introduced weevil Sitona line at a L. is again attracting attention in the island counties of Washington State. This insect was first discovered, on Vancouver Island, British Columbia, in the spring of 1937- A single specimen of this weevil has also been found at Moscow, Idaho. It is a European pest which occurs in practically all the countries of Europe, in- cluding the British Isles, where on many occasions it seriously defoliates cultivated leguminous plants. In this country it attacks vetch, peas, and alfalfa, and in Europe it is recorded from practically all of the cultivated legumes and a few other plants.

GENERAL E ..E E D E R S GRASSHOPPERS (Acrididae)

Nevada. G. M. Shogren (March 30): Field examinations of egg beds of Melano-

plus mexicanus (Sauss.) and dif ferentialis (Thos.) show that egg de-

velopment is nearly complete, with segmentation and eye-spot stage com- monly found. >

Arizona. 0. L. Barnes (March 10): Hatching of M. mexicanus began about Febru-

ary 15-20 in Maricopa County. First-, second-, and third-instar nymphs were taken in the Tempe area on March the greater number being in first instar. Only first- instar nymphs taken in alfalfa fields, the more ad- vanced nymphs being swept from sparsely vegetated places. E. E. Russell observed early instar nymphs in the Buckeye area late in February. First- to third-instar nymphs were observed in alfalfa fields and along field margins at several locations in Yuma County on March 2-3 Hatching in al- falfa fields apparently began a week or 10 days earlier in Yuma than in Maricopa County. Nymphal populations were very low in all areas visited, indicating that only a very small percentage of the eggs had hatched up to March 2-5« No hatched egg pods found in one area in Yuma County, but scattering early instar nymphs indicated that some hatching had occurred. Hatching began at about the normal time, or slightly earlier,

D. K. Scharff "'(March 21): Light hatch of M. mexicanus in progress in

range-land areas in the lower elevations of Cochise and Graham Counties, with hatch. less than 1 percent complete over the area as a whole.

MORMON CRICKET (Anabrus simplex Hald.)

Nevada. J. C. Hamlin (March 28): Hatching began in Sonoma, Mountain range,

south of Winnemucca, during the third week of March, progressed slowly during the succeeding week,' and was more advanced in the lower, drier parts of the several canyons, where hatch ranged from 30 to 47 percent. Hatching had not begun in higher, wet portions of these canyons. Eggs de- posited by the lower of 2 bands of crickets that inhabited the study area (Elbow Canyon) during 1941 showed 30-percent hatch on March 23* Of the 272 unhatched eggs examined, 17 percent were unviable and 43 percent con- tained nearly fully developed embryos, but 40 percent showed little or no embryonic development. The undeveloped eggs are being watched with inter- est, as they may possibly be those deposited after the adult crickets be- gan subsisting on the young succulent Junegrass (Bromus tectorum) , which sprouted early in August following rainy weather, rather than in the fall as usual.

Oregon. L. D. Cowden (March 19): Eggs began hatching on February 13 at Warm

Springs, Wasco County, and on March 8 in Gilliam County.

COULEE CRICKET (Peranabrus scabri colli s Thos.)

Oregon. L. D. Cowden (March 19): Twenty percent of eggs hatched by March 7

on east side of Deschutes River, Wasco County.

EUROPEAN EARWIG (Forficula auricnlaria L.)

Colorado. F. H. Gates (March 24): An infestation, 3 miles from the original

infestation, was observed in an auto camp last fall, near Denver.

-21-

CUTWORMS ( Phalaenidae )

Virginia. H. G. Walker and L. D. Anderson (March 26): Reported damaging ca-

mellia buds near Norfolk.

Mississippi. G. L. Bond (March 25): Cutworms are injuring garden plants in

Jackson County.

N. D. Peets (March 25): The black cutworm (Agrotis ypsilon Rott.) is

attacking tomato plants in Lincoln County.

Colorado. C. R. Jones (March 25): A few cutworms are reported*

Nevada. G. G. Schweis (March 23): Outbreak of the arny cutworm (Chorizagrotis

auxiliaris. Grote)reported from Lyon County. (Det. by C. Heinrich.)

G.M. Shogron (March 30): Infestation of C. auxiliaris reported from

Mason Valley area of Lyon County in the latter part of February. Early in March this infestation spread over approximately 2,000 acres, with average population of about 10 larvae per square foot. Observations on March 20 indicated that this insect was no longer any threat to ’agricultural lands in the vicinity. The last observation noted an average of only 1 larva per square yard. The habitat was principally idle land, predominating plants being Russian- this tie and sagebrush. Indications in Smith Valley, Lyon County, are that an epidemic of A. yppilon may. materialize.

However, as spring cultivation and irrigation oegin, larval concentration may be materially reduced.

SUGAR BEET WIREWORW (Limonius calif ornicus Mann.)

California. M. W. Stone (March 2): At Oxnard, Ventura County, 15 acres of

recently transplanted carrots grown for seed were infested with an average of 7*5 wireworms per carrot. Wilted plants in a 60-acre lettuce planting were infested with an average of 5*3 wireworms per plant. Counts in sev- eral rows showed from 18 to 45 percent of the plants missing.

C. E. Woodworth (March 9): One male recovered from head of broccoli

in a store in Los Angeles area. The insect is in full emergence but not as yet out of the ground locally. .This observation shows clearly a means -of distribution of this pest to a noninfested area* (Det. by M. C. Lane.)

A SCARABAEID (Rhizotrogus solstitialis L.)

New York. A. Boving (February): Larvae received which were occurring in

numbers in a cemetery at Geneva and were seriously damaging the sod. This is a very injurious European species.

JUNE BEETLES (Phyllophaga spp.)

Florida. A. M. Phillips (March 24): Adults found in pecan nursery at Monti-

cello.

CEREAL AND FORAGE-CROP INSECTS WHEAT AND OTHER SMALL GRAINS GREEN BUG (Toxoptera gramlnum Rond.)

Virginia. A. M. Woodside (December 12): In one field in August County, bar-

ley plants were killed over an area 50 feet long and 20 feet wide, but

-22-

the infestation extended only 2 or 3 feet beyond this killed area.

(Det. by P, W. Mason.)

Georgia. T. L. Bissell (March 24) : On March 6, aphids were very scarce in

one oats patch examined. Only 3 aphids found in a 10-minUte search.

No dead plants observed.

Oklahoma. R. Dahms (March 24): Causing damage to small grains in Cotton,

Tillman, Comanche, Caddo, and Grady Counties. Volunteer fields of win- ter oats, barley, and wheat showing the most injury. Spring oats' and barley are being infested as the plants emerge and in some cases are being killed in the seedling stage. '

F. A. Fenton (March 25): Apparently an 'increase in spread of infes-

tation. Reports received from Wynn Wood, Garvin County, and Temple, Cotton County. . .

, C. F. Stiles (March 30): GreenSfaugs are occurring in damaging num-

bers in Cotton, Garvin, Marshall, Bryan, and Choctaw Counties. Some of the fields, especially in Bryan County, were destroyed by March 21.

There was a heavy winged northward movement of green bugs in Bryan County on March 19. Barley and oats being damaged as far north as Stillwater, Payne County.

Mississippi. S. L. Calhoun and E. W. Dunnam (March 28): Heavy infestation

observed at Stoneville. .The' cool weather has not been favorable for parasite development, although a few parasitized aphids are present on the most heavily infested plants. Many winged forms of aphids are now in the air.

Texas. ,F. L. Thomas (March): Severe damage by the green bug in Swisher,

Hardeman, Wilbarger, Cooke, Grayson, Fannin, Denton, Dallas, Kaufman, Limestone, McLennan, Bosque, Coryell, Lampasas, Burnet, Tom Green,

Taylor,' and Eastland Counties. First time that green bug damage has ever appeared, according to some reporters in west-central part'. Oats have been plowed up and other crops planted. Late wheat is being most severely damaged where it has not yet begun to joint. Infestation light west of Hardeman County. Excess' rain in summer and fall' may have stimulated volunteer wheat and oats. Dry, cool January, February, and March also favorable for bugs,

E. W. Laake (March 19): Damage to oats in Collin, Cooke, Dallas,

Denton, Ellis, Fannin, Grayson, Hill, Kaufimn, Navarro, Rockwall, and Tarrant Counties has been estimated at 6,800,000 bushels. I am sure that the area infested is far more extensive than indicated. This out- break is definitely the most severe that has occurred since 1907, when the estimated loss was not less than 50,000,000 bushels of oats and wheat in Kansas, Oklahoma, and Texas.

K. P. Ewing (March 26); Two hundred acres of oats at Riesel,

McLennan County, are being destroyed.

CHINCH BUG (Blissus leucopterus Say)

Illinois. W. P, Flint (March 24): Wintered in very good condition. Ex-

aminations show less than 2 percent of dead bugs. No movement out of winter quarters.

Kansas. H. R. Bryson (March 24): The largest number of chinch bugs went

into hibernation in the fall of 1941 in the eastern third of Kansas of any year of which there is an authentic record. No evidence that the winter has caused any great mortality. There is reason to believe bugs will be a menace unless environmental conditions inhibit their develop- ment this spring. The heaviest infestation coincides to some extent

~ 23-

wit h that of the bluestem region.

Oklahoma. R. G, Dahms (March 24) t Winter mortality in southwestern Okla- homa was less than 2 percent in bunchgrass and about 6 percent in sor- ghum stubble. Many bugs left winter quarters on March 15 and some eggs were being laid 1 week later.

HESSIAN FLY (Phytophaga destructor Say)

Kansas. H. R. Bryson (March 24): Planted wheat and volunteer in the east-

ern third of Kansas are heavily infested. Serious injury has already resulted in some localities and greater damage expected than for several years.

ALFALFA

ALFALFA WEEVIL (Hyp era postica Gyll.)

Nevada. G. M. Shogren (March 30): Cold unsettled weather caused adults to

remain inactive and is responsible for withholding of egg hatches.

California. A. E. Michelbacher (March 23): On March 18 in the northwestern part of the San Joaquin Valley the maximum number of larvae per 100 sweeps of the insect net was 268, a great reduction as compared with last year. On March 14, 1941 » as many as 2,734 larvae were collected per 100 sweeps.

apple orchard at Cranston on March 6.

-24-

SAN JOSE SCALE (Aspidiotus perniciosus Comst.)

Illinois. S. C. Chandler (March 4): Counts made for week ended March 4

in southern Illinois show from 21 to 64 percent of scale dead, which is not more than normal mortality.

Mississippi. C. Lyle, et al. (March 25): Infestations on peach trees were

reported from Jasper, Holmes, Tate, and Tunica Counties, as well as from the Jackson district and the southwestern counties, especially on unsprayed trees*

Arizona. F. H. Parker (March 19): Found in Tempe area on roses, apple

trees, and plum trees but no severe infestation.

APPLE

CODLING MOTH (Carpocapsa pomonella L.)

New York. D. W. Hamilton (March 27): Early dry fall of 1941 in Poughkeepsie

provided ideal conditions for winter hibernation of larvae. Number of larvae in hibernation at least normal. Mortality counts of. overwintering larvae made on March 25 showed 16.6 percent dead in one orchard and 12 percent in another.

Illinois. W. P* Flint (March 24): Examination in various parts of Illinois

show somewhat conflicting results regarding 'winter kill of .codling moth, with dead or killed ranging from 15 to 50 percent. The survival will be about normal, and, with the number of larvae that went to winter, quarters, it appears that the spring brood will be very large.

EASTERN TENT CATERPILLAR (Mala cosoma americana F.)

Mississippi. C. Lyle and J. G. Hester (March 25): Many webs observed on

black cherry and peach in Choctaw, Webster, and Oktibbeha Counties today. Apparently more numerous than in 1941.

PLUM CURCULIO (Conotrachelus nenuphar Hbst,)

Georgia. 0. I. Snapp (March 20) : Plum curculio adults began to appear on

peach trees from hibernation at Fort Valley, in central Georgia, on March 16. There were scattered open Elberta and Riley (first blooming varieties) blooms when the first plum curculios were jarred from peach trees on March 16 and, although 75 percent of the Elberta blooms were open on March 19, the curculios had not appeared from hibernation in large numbers by that date. Mortality of field-reared and fed adults in hibernation last winter was rather high, with survival of 11.2 and 75*3 percent, respectively.

SPOTTED CUCUMBER BEETLE (Diabrotica duodecimpunctata F.)

Georgia. 0. I. Snapp (March 19): In Fort Valley adults are appearing from
