OUTSTANDING ENTOMOLOGICAL FEATURES IN THE UNITED STATES FOR MARCH, 1930 
Present indications are that white grubs will be unusually des tractive 
in the East Central States and northward into Wisconsin. 
The pale western cutworm and the army cutworm are already appearing 
in destructive numbers in several of the Western States from Oklahoma to 
Nebraska. Reports have also been received of serious cutworm damage from 
the Gulf region. 
The Hessian fly was first observed on the ^ing at Manhattan, Hans., 
on March 19. 
The green bug is reported as being very abundant in south-central 
Kansas. 
By the third week in March adults of the alfalfa weevil were becoming 
active in Nevada. 
The pea aphid was starting to infest peas in the trucking sections 
of Virginia during the last week of March, and alfalfa was very seriously 
damaged early in the month near Fresno, Calif. 
Fruit aphid eggs were starting to hatch in the third week in March 
in Delaware, central Illinois, and Ohio. 
Heavy winter mortality of the codling moth is reported from Idaho, 
Utah, and Washington. The mortality in the Pacific Northwest was in 
larvae above the snow line, so the actual survival is much higher than 
this mortality would indicate. Larvae were commencing to pupate in New 
Mexico in the latter part of the month. 
The eastern tent caterpillar seems to be less numerous than usual 
in New England and normal or above normal in numbers from Virginia south- 
ward. Eggs were observed hatching during the second week in March in 
-43-
