 the pods in the field, and the larvae develop 

 in the dried seeds and the emerging beetles 

 leave round holes. Fumigate with carbon 

 disulphide or cover with air-slaked lime.

Green Pea Aphid : Sucks the sap from 

 stems and leaves in June, often causing

 the surface to a foot 

 from the ground.

 emerging through small "shot holes." 

 Burn infested trees and keep others thrifty.

San Jose Scale : 



Small circular shells 

 containing insects

 branches the latter part of Summer. Clip 

 off and burn nests when small. Spray
