APPLE INSECTS

30 days for the first brood and 3 weeks for the second. The 

 full grown larva is about f inch in length, pinkish white in color, 

 with the head dark brown and the thoracic and anal shields 

 lighter brown (Fig. 11). 



The larger part of the larvie leave the fruit before it falls and 

 crawl down the brancln^s until they find a suitable place for 

 spinning the cocoon. After making the cocoon the larva may 

 do one of two things, eitlier it will remain in the larval condition 

 until the following spring or it may change to a pupa in about 

 a week. In the latter 

 case these summer pupa? 

 give rise in about 10 days 

 to a brood of moths which 

 lay the eggs for the second 

 generation. In New 

 York only part of the 

 larvae spinning up before 

 August 1 transform the 

 same season, all the larva) 

 going into cocoons after 

 that date hibernate. In 

 Arkansas the correspond- 

 ing date is September 1. 

 Not all the larvae of the 

 first broods transform the 

 same season even in 



Georgia, where there are three full generations, l)ut they 

 relatively few. 



The number of generations a year varies in different parts 

 of the country, and has been a difficult question to solve, owing 

 to the overlapping of the broods. The earliest of the first 

 brood moths will be on the wing before belated individuals 

 of the spring brood have disappeared. It is now, howev(T, 

 pretty well determined that in the North, — New England, New
