SEASONAL-HISTORY STUDIES OF 1914. 



The life-history studies of the codling moth which were com- 

 menced in 1913 were continued during the season of 1914. Although 

 the notes secured in 1913 were complete in themselves, it was con- 

 sidered desirable to extend the observations over a period of at least 

 two seasons, in order to note any differences in the behavior of the 

 insect due to climatic variations. All of the explanations and 

 descriptions of the methods used in the studies of 1913 are applicable 

 to the investigations of 1914. 



SOURCE OF REARING MATERIAL. 



The overwintering larvae consisted of the larvae which were reared 

 under laboratory conditions and the larvae collected from the banded 

 trees, as well as miscellaneous larvae which were secured from wormy 

 apples. The miscellaneous larvae passed the winter in corrugated 

 paper strips, while the remainder of the larvae wintered in the 

 " cocoon racks." The larvse were kept under normal outdoor 

 conditions throughout the winter.
