Corn earworm in Georgia.--Geo. W. Barber, Savannah, Ga., reports 
that in Chatham County pupae of Ieliothis obsoleta Fab. are present in 
the soil through the year, natwithstanding the long warm summer in this 
latitude. Although in some years moths begin to emerge from hiberna-— 
tion the last week of March, such emergence may not be completed until 
the last week of July. During this emergence period certain groups may 
have passed through three or possibly four generations in tne field, 
as a generation occupies approximately a month. Some of the individu— 
als that mature in June and July remain dormant as pupese in the soil 
in increasing numbers from June on, although larvae are found in the 
field until the middle of October. 
Hessian fly control in the East.--Fall surveys and seeding-—date 
plot sampling in the East Central States were completed, except in 
Tennessee, with results from 280 fields showing an average stem in- 
festation of only about 1 percent. In the most keavily infested sample 
taken only 40 percent of the stems contained flies. The stages chief-— 
ly present in November in sown wheat throvghout the territory were 
from half~grown to mature larvae. 

Hessian fly infestations in winter wheat.-—-Summarizing surveys 
made by } H. H. Walkden, BE. T. Jones, and himself, J. R. Horton, Wichita 
Kans., says; "The principal activity in November has been the sampling 
of hessian fly date-~of~sowing plots and making a survey of infestations 
in winter wheat over the west central region. The eee eri from the 
survey has not been completed but advance indications ere that the fall 
sowings are lightly to moderately infested in most of the eastern third 
of Kansas, in northwestern and southwestern Missouri, and in south cen— 
tral Nebraska; in the central and southeastern portions of Missouri 
early sown wheat is moderately to heavily infested, most fields, how— 
ever, being estimated as sown too late for effective infestation. In 
Oklahoma the fly shows indications of increase over wnat was found in
