Fuller's rose "beetle was not very materially affected "by temperatures 
ranging from 4 ? to 15*^ "below zero in parts of Georgia. Of 57 heet].es

mortality as occurred in previous winters. 
Seed-corn m.aggot was generally prevalent in southern Virginia and 
South Carolina. 
A spring survey indicates 34 percent of the wheat plants in some sec- 
tions of Illinois infested with hessian fly.

Very mild winter weather was accompanied "by a.ctivity of the alfalfa 
weevil in the San Joaquin Valley of California,.

the killing of peas in that region "by the cold weather. In California 
this insect is quite abundant in alfalfe field.s in the San Joaquin Valley.

County, Oreg., 10 m.iles south of any previous record.

killed "by the cold weather. Those in "buried trash arc coming through the 
winter in very good condition.

weather in southern Illinois, where 15° "below zero Fahrenheit was recorded 
at most of the ixlaces where samples were taken.
