THE PLUM CURCULIO. 



The plum curculio is a serious enemy to stone fruits and is par- 

 tial to plums. The accompanying illustration shows its method 

 of injuring plums. It is an insect pest of first class importance and 

 has in some sections practically killed the industry of plum growing. 

 Besides attacking the plum it breeds in great number in cherries, 

 peaches, appricots, nectarines, quinces, apples, crabs, and haws. 



Its means of distribution is principally in the larval stage through 



18. The Plum Curculio, (Lugger).
