SMALL WORMS WORKING IN THE SEED 217 



attack, the worms first eating the foUage and then boring into the 

 fruit. The full-grown worm is f to 1^ inches long, yellowish in color, 

 and marked with two narrow light stripes down its back. The adult 

 has white wings, broadly bordered with dark brown. The winter is 

 passed as a pupa in folded leaves on the ground. There are three to 

 four generations annually. ' The species is most injurious in the Gulf 

 states. 



Since the worms devour the foliage before feeding in the fruit, the 

 best remedy is to apply arsenate of lead or Paris green to the vines. 

 Crop remnants should be cleaned up, and fall plowing is advisable. 

 Early squashes may be used as traps, to divert attack from melons. 



The Pea-moth {Cydia (Semasia) nigricana Steph.) 



In northern sections growing peas are subject to infestation by a 

 cylindrical, light yellow larva, half an inch long when full grown, 

 which works in the young seed within the growing pod. Infested 

 pods ripen early, crack open, and the worm then emerges and goes 

 into the ground to transform. The eggs are laid on the pods about 

 the close of the blossoming season. Arsenate of lead or Paris green 

 applied at this time and again in ten days will check the pest. Early 

 peas are not usually much infested, and the same is true of very late 

 varieties. 



The Clover Seed-caterpillar (Laspeyresia {Enarmonia) interstinctana 



Clem.) 



Tiny, whitish worms, a third of an inch long when full grown, work 

 in the growing heads of clover, eating the florets or the soft, forming 

 seeds. In their work they hollow out a cavity in the head, which fails 

 to bloom or often blooms on one side only. If a head is torn open, 

 the caterpillar will be found inside. 



The adult moth appears at the time of the first blooming of clover. 

 Succeeding generations are on the wing at the time of the second 

 blooming, and again in late summer. Hibernation takes place as 

 pupae in silk cocoons on the ground, or sometimes as adults.
