CHERRY INSECTS 69 



The cherry-tree leaf-roller ^^ (Archips cerasi- 



V or ana) 

 Order — Lepidoptera 



This pest is often seen on choke cherries; the 

 eggs are laid in patches on trunks or branches near 

 the ground; they remain here unhatched until the 

 following spring; when they hatch the green larvae 

 crawl up to the branches where they begin to draw 

 the leaves toward each other and tie them together 

 with silk; in this way they build large ugly nests, 

 inside of which they live and eat the leaves ; the 

 larvae pupate in these nests and the moths appear in 

 June and July ; one brood a year. 



Control — Cut out nests and burn before moths 

 appear. 



Cherry leaf-miner ^^ (Profcnusa coUaris) 

 Order — Hyriienoptera 



The larvae mine in the leaves of cherries ; interior 

 of leaves all eaten out and leaf then turns brown 

 and a large ''blister" is formed; principal damage 

 occurs during last week of May and early part of 

 June; the larvae go into ground to hibernate. 



Control — Plow and cultivate ground in late fall 

 to destroy larvae; pick off the infested leaves and 

 destroy them. 



Shot-hole borer — Discussed under peach pests. 

 It is often a serious pest on cherries. 



The pear slug — Often a serious pest on cher- 

 ries; discussed under pear pests. 



The plum curculio — Often a serious pest on 

 cherries; discussed under plum pests. 



Control — Spray sour cherries with arsenate of 

 lead, 3 pounds to 50 gallons just after petals fall as 

 the young cherries are bursting through the calyces ;
