as an enemy of the European corn »orer, namely Exeristus roborator Fab., has 
been recovered fron the field by the collection of corn borer larvae from 
“which the parasite has been reared, It seems ex ctremely probable, therefore, that

FRUIT INSECT INVESTIGATIONS 
A. L. Quaintance, Entomologist in Charge 
Fred E. Brooks, in charge of the French Creek, Ws Va., station, sends 
ithe following statement: 









if "Considerable injury is occurring to the hickory and pecan trees of 
_ the Arrovfield nursery at Petersburg, Va., from Pseudibidion unicolor (Rand,). 
‘The larvae, just before maturing, sever the wood of stems and branches up to 
-@n inch or more in diameter and then pupate just above the point of injury. The 
bark at the girdle is left intact, but the wood above dies and soon breaks 
ee - The injury is especially noticeable to young trees in the nursery row. 
"Larvae and pupae of Balaninus are being collected here for systematic 
‘study by Richard 1. Cotten, of the division of Stored-Product Insect Investi- 
gations, Specimens in these stages of the considerable number of closely 
lilied snecies attacking acorns are being obtained and coordinated with the 
parent adults by confining mating pairs of beetles early in the season in 
cotton bags over oak branches bearing sound acorns. 
"in several localities of central West Virginia the grape curculio, 
Cravonius inaequalis Say, is occurring in great numbers and ruining the grape 
‘erop On unsprayed vines. At the present time, July 16, fully half of the 
fruits at this station are infested."
