The adult beetles are about three- 

 eighths of an iijch long, brownish black 

 in color with well-defined light spots on 

 the wing covers and a distinct white 

 spot on the hinder part of the thorax 

 near the base of the wing covers. The 

 eggs are very small (1.5 mm. long) and 

 deep yellow in color. The larvae are 

 yellowisli in color witli a dark head. The 

 pupae are first light, gradually becoming 

 darker with age. 



Life History 



The adult hibernating weevils appear 

 in the spring and as soon as the pods 

 are formed on the vines begin egg-laying. 

 The eggs are thrust inside of the pod 

 by the females, thus being thoroughly 

 protected and out of sight. The young 

 grubs, as soon as hatched, bore into the

tender peas and remain inside, drilling 

 out sufficient room until they are ready 

 to emerge as adults in the fall. This is 

 accomplished by cutting a circular hole 

 in one side of the pea. Unlike the bean 

 weevil, this species works only upon the 

 peas originally attacked when green and 

 does not continue to breed upon dried 

 and stored seed. There is but one un- 

 even brood a year. 



Foods 



Works upon all varieties of garden and 

 flower peas. 



Control 



As the seed is infested before harvest- 

 ing, control measures are of little avail, 

 except to prevent a reinfestation by 

 means of the seed. A thorough fumiga- 

 tion with carbon bisulfid is a sure way 

 of accomplishing this.
