THE CODLING MOTH IN THE OZAKKS. 



15 



SECOND-BROOD MOTHS. 



Moths of the second brood were obtained from reared material 

 July 25. Moths emerged in abundance during August and in dimin- 

 ishing numbers throughout September. The last one to emerge out 

 of doors appeared October 1. 



The earliest moths of this brood were not obtained in sufficient 

 numbers to get the first possible third-brood eggs. Oviposition in a 

 cage began on August 5 by moths the first of which emerged July 30. 

 The record of tins cage is given in Table XV.

LENGTH OF LIFE CYCLE OF SECOND GENERATION. 



The interval between the emergence of the earliest first-brood 

 moth (June 8) and the earliest of the second brood (July 25) gives a 

 period of 47 days for the life cycle. Records of 19 individuals, the 

 larvse being reared in bagged fruit on trees, give an average of 49.5 

 days from oviposition to emergence. Adding 5 days as the interval 

 from emergence to oviposition gives 54.5 days as the total for the gen- 

 eration. The minimum time thus shown was 45 and the maximum 

 67 days. Records of these 19 individuals are given in Table XVI.
