CHEREY IXSECTS. 



CURCULIO. 



This insect injures cherries by causing the fruit to become 

 wormy. It is the same insect as the plum curculio and is dis-

 may be mixed with the Bordeaux mixture if desired as stated on 

 page 417. Make the first application immediately after the 

 blossoms have fallen and a second about ten days later,
