The Plum Curculio In Apples 

 In Massachusetts 



W. D. Whitcomb 



The plum curculio is the most injurious insect pest of apples in Mass- 

 chusetts, frequently damaging more fruit than all other insects together. 

 As a result of the heavy loss to fruit growers, studies of this insect were 

 begun in 1926 in the eastern part of the State, and this bulletin reports the 

 progress of the work to date.
