HESSIAN FLY 
At harvest tine the surveys of wheat stubble, made by the Bureau of 
Entomology and Plant Quarantine field stations and cooperating State agencies, 
indie- ted that hessian fly infestations were low in wheatfields throughout 
Maryland, Delaware, Virginia, north-central North Carolina, Tennessee, southern 
Illinois, and central and western Kansas. Infestations ranged from low to 
moderate in eastern and south-central Pennsylvania, Kentucky, southern Indiana, 
southern Michigan, Missouri, Iowa, eastern Kansas, and southeastern Nebraska* 
There were menacing populations of flied in local fields in most of the States 
or districts. Prom moderate to heavy infestations of the hessian fly were re- 
corded in north— central and western Pennsylvania, north-central Ohio, the north, 
em two— thirds of Indiana, and central Illinois, and in these areas the fly was 
most menacing. Conditions were favorable for the hessian fly and for growths 
of volunteer wheat during the early part of the- summer but most unfavorable 
during tho fall period. Owing to the drought during September and October, 
most wheat was not planted until the suggested safe-seeding dates and as for th< 
few early seeding? very little came up in advance of the regular seeding. • Thert 
was some late emergence of the fly in October but oviposit ion was low and larval 
establishment generally low or lacking. Occasional light infestations were 
found in regular fall wheat seeding? in Indiana, Illinois, Maryland, Pennsyl- 
vania, Kansas, and Missouri, .with possibilities of minor infestations in local 
fields, but with little likelihood of severe or general injury to the 1940 crop 
in any part of the Wheat Belt. (W. 3. Cartwright, Bureau of Entomology and Pla?-

ALFALFA WEEVIL 
The following summary of alfalfa weevil- conditions during 1939 is based 
on reports from State and county officials, supplemented by iimited observa- 
tions of the alfalfa weevil laboratory staff. Data assembled by W. E. Shull 
indicate that in Idaho severe weevil damage was general in the upper Snake 
Diver Valley acid ™as spotted in south-central counties and in the western 
counties of Canyon and Owyhee, Severe damage was general in Douglas County and 
™as spotted in Churchill, Lyon, Washoe, and Elko Counties, Nev. , according to 
G-eorge 0. Schweis. W. W, Owens reports that weevil damage was fairly common 
in Utah, being most severe in Sanpete and Sevier Counties and in the seed areas 
of Millard and Uintah Counties, In California this season weevil abundance 
reached a general level from three to four tines as great as during any previous 
s eas on but, notwithstanding this fact, damage was negligible. In western Colo- 
rado economic damage was confined to a few fields, weevil injury being consider- 
ably less than in 1937 and 1938, according to J . H, Newton, There was no dam- 
age to the first crop in the Rogue River Valley of Oregon, and in Nebraska, ex- 
cept for a single field in the western part of Scotts Bluff County, no notice- 
able damage occurred. C. L. Corkins reports alfalfa weevil damage in 1939 ns 
the most severe ever experienced in Wyoming, particularly in Fremont and Uintah 
Counties. In ether sections of the weevil territory damage was slight, negli- 
gible, or unreported. The season’s scouting by Federal and State officials, al- 
ready reported in the- Insect Pest Survey Bulletin, resulted in original dis- 
covery of the alfalfa weevil in Crook County, Wyo., Larimer County, Colo., and 
Morrill and Sheridan Counties, Nebr. , and confirmed discovery of the weevil in 
s Horn Countv, Mont., during 1938. (J, C, Hamlin, Bureau of Entomology and
