CLASSIFICATION AND DESCRIPTION OF COMMON INSECTS 227 



Eggs. — ^Laid in the growing pod; hatch in about 2 weeks. 



Larva. — A small whitish slightly hairy caterpillar with pale brown 

 head and thoracic shield; about }2 inch long when full grown, feeding 

 within the pod on the green peas. 



Pupa. — In a small oval cocoon in the ground near the surface. 



Life-history. — Early in July the moths emerge from cocoons in 

 the ground, and begin egg-laying; larvae hatch out in about 2 weeks. 

 About the end of July the larvae emerge from the pods and spin small 

 oval cocoons near the surface where they remain all winter. 



Control. — Sow early varieties; sow very late; deep fall plowing of 

 infested land; spray after blossoming with soap and Paris green and 

 repeat in 10 days. 



Lesser Apple Worm {Laspeyresla primivora Walsh). — (Consult 

 Bulls. 68, Part V, and 80, Part III, Bureau of Entomology.) The 

 early work of this worm is similar to that of the Codling Worm, 

 only nearer the surface on the flesh just under the skin; the young 

 larvae hatched in August often eat on the surface of the fruit. Two 

 broods in the Northern States, and one in Quebec and northern Ontario. 



Adult. — Ground color of fore wings brown with pale rusty-red 

 patches, and with grey, yellowish-white and blue oblique hnes; hind 

 wings dusky grey at base, shading to black at apex. Appears in early 

 June about the same time as the Codling Moth, and again in August. 



Eggs. — Glistening white, minute, flat, oval, and covered with net- 

 work of irregular ridges. Deposited on both sides of leaves, but on 

 upper surface of fruit, stems, etc; hatch in 4-6 days. 



Larva. — Full-grown larva 3^^-)^ inch long; reddish flesh-colored 

 above, lighter below; head brown; thoracic shield yellowish, transparent; 

 anal plate brownish, with a brownish comet-like structure on the 

 caudal curvature, and with an anal fork; mature in June and July. 

 Many of the second brood larvae enter the fruit on the side. Time 

 in fruit 2-4 weeks; larva in cocoon before pupation 7-8 days. 

 Larvae of second brood winter over. 



Pupa. — ^Pupation in spring; cocoon densely lined inside with whitish 

 silk; pupa brown, 3^^ inch long; pupation stage about 10 days. Empty 

 pupal case usually attached to cocoon. 



Control. — As for Codling Moth but spray again in August; destroy 

 hawthorns in vicinity.
