SU.MMARY FOR SEASON OF 1912. 



Spring-brood moths began emerging in the laboratory May 18 and 

 probably several days earlier in the field. Ten to 12 days later first- 

 brood larva) were probably beginning to enter fruit. First-brood 

 larvaj began leaving the fruit June 11. First-brood moths emerged 

 July 2 to August 21, and second-brood larvae probably were entering 

 fruit by July 12. Soon after August .5 to 9 the number of larvse 

 appearing under the bands increased, and most of the larva; taken 

 after this date may be considered to be of the second brood.
