DECIDUOUS-FRUIT INSECT INVESTIGATIONS 
A. L. Quaintance, in Charge 
O. I. Snapp, in charge of peach-insect investigations at Fort 
Valley, Ga., writes that the present curculio infestation in the Georgia 
peach belt is the heaviest in eight years. A vigorous campaign of sup-— 
pression is being waged in order to control the second generation, which 
will attack the matured fruit. A heavy infestation was anticipated, on 
account of the quantity of wormy peaches left in the orchards last year, 
and the low mortality of adults during hibernation. 
Contributions from the Japanese-—Beetle Laboratory 
W. A. Baker, of the field laboratory at Monroe, Mich., for the 
study of the European corn borer, visited the Laboratory on April 21 to 
study the various methods used in rearing parasites of the Japanese 
beetle. 
Lead arsenate, in the form of a top dressing, applied to turf 
for the control of Japanese beetle larvae, is being extensively used in 
the infested area this spring. On the Lansdowne, Pa., golf course the 
putting greens were treated with it in the autumn of 1928 and again in 
the spring of 1929. Lead arsenate was applied at the rate of 5 pounds 
to 1,000 square feet for each treatment. Examination of the turf on 
April 30 revealed no living larvae. The degree of infestation in the 
autumn of 1928 was more than 35 larvae to each square foot. 
Loren B. Smith was recently elected President, and C. W. Bailey
