MISCELLANEOUS PESTS 



These pests are placed here because their characters or habits are such that 

 they cannot be grouped with others. The following table distinguishes them: 



Mostly green 1 



Not green 2 



1. Working only inside the berries cranberry fruitworm (p. 51). 



Feeding mainly on the blossoms and small berries, slug'like bog butterfly*''. 



2. With a head; working in the blossom buds cranberry weevil (p. 56). 



Headless; working in the tips of the uprights cranberry tipworm (p. 6U).

Cranberry Fruitworm ■*" 



This worm has been more destructive on the Cape than any other cranberry 

 pest, sometimes taking nearly half the crop; but nature controls it some years so 

 that it does no great general harm. It is usually much more harmful around 

 Plymouth and on the outer Cape than elsewhere, seldom troubling bogs much in 

 Middlesex County and other areas well inland. It often takes all the fruit on a 

 bog without proper winter flowage. It attacks early varieties more than late ones. 

 It is also very injurious in Nova Scotia and Wisconsin, but is less troublesome 

 in New Jersey and on the Pacific Coast. 



Many moths probably come onto the bogs from a standing upland infestation 

 most years in Massachusetts and Wisconsin, for new bogs made in isolated loca- 

 tions nearly always become infested in a few years. Infestations on bogs flooded 

 during the winter might die out soon but for this continual invasion. 



^^ Production of males is excessive in this species, and the egg laying capacity is 

 relatively low. The worm works in June and sometimes is rather harmful. It can 



be controlled easily with a spray of lead arsenate. It is about three-eighths of an 

 inch long when full grown. See figs. P, Q, and R, and figs. 13a and 13b of Plate Three.
