298 INSECT PESTS OF FARM, GARDEN AND ORCHARD 



after sunset, and deposit one to three eggs on young pods. The 

 caterpillar hatches in about fourteen days, according to European 

 observations, and attacks the forming seed. Affected pods usu- 

 ally ripen early. The larva is whitish-yellow with a pale brown head 

 and thoracic plate, and about one-half an inch long when full 

 grown. With the opening of the pod the larva crawls out and 

 enters the earth where it spins a very thin silken cocoon. The 

 length of the pupal stage and the method of hibernation do not 

 seem to be well established. Very early and very late varieties 

 are but little injured. 



Remedies. This suggests one of the best means of handling 

 this pest to be the growing of early varieties, such as Alaska, 

 American Wonder, Gregory's Surprise, Nott's Excelsior, and 

 McLean's Little Gem. If the crop is known to be infested, clean 

 up the vines and burn them as soon as it is picked. Spraying 

 with arsenate of lead will doubtless aid in the control where in- 

 festation is serious.
