OUTSTANDING ENTOMOLOGICAL FEATURES FOE APRIL, 1922 
The Hessian fly situation remains unchanged over the greater 
part of the wheat-growing sections of the country. Infestation is 
reported as very light in Ohic, Indiana, and Kansas. A moderate 
infestation is reported from Lancaster and Cass Counties, Nebr. , 
and a rather alarming situation is reported from Madison and Warren 
Count ias, Iowa. 
Chinch bugs passed the winter with hut very low mortality in 
Indiana, South Dakota, Illinois, and Missouri. Heavy rains in 
central Illinois destroyed some of the hugs* Floods in Missouri 
deposited large numbers of bugs over regions which had beer cleaned 
up by burning during the fall and winter. These bugs do not seem 
to have suffered from the effects of the water. 
The green bug, with other aphids, is reported as quite serious 
in parts of Tennessee, This pest is spreading westward 'across the 
State of New Mexico where it is reported as destroying approximately 
SO per cent of the wheat. 
The false wireworms reported in the last number of the Survey 
Bulletin are still seriously destroying wheat in Nebraska. A similar 
condition is reported this month from the western half of South Dakota. 
The San Jose scale is still on the increase in the Middle Atlantic 
and East-Central States, being reported as serious in Rhode Island, 
New York, New Jersey, Indiana, Wisconsin, Missouri, and Georgia. 
Dormant spraying in Georgia did not appear to be effective in the 
control of this pest. 
A new enemy of grapes was reported from Nevada as doing serious 
damage in all vineyards in the Las Vegas Valley by eating into the 
buds. Specimens which accompanied the report have been identified 
as the chrysomelid Glyptoscelis squamulata Crotch. 
Seed-corn maggot has never been observed in such numbers as are 
now present in southern New Jersey, 
Two rather unusual tomato pests are reported from Arizona, 
Trichobaris mucorea Lee. and Ulus crassus Lee. 
The pea aphis is reported as seriously threatening cannery 
peas in parts of Delaware. The region so seriously infested last 
year in the Santa Clara Valley of California by this pest is only 
very lightly infested so far this year.
