a Pupated in fruit. 



As indicated in the table, 5 of these larvae lived over winter, while 

 the others developed to second-brood moths. No attempt was 

 made to secure third-brood eggs from these moths, but from the time 

 of their emergence we should expect third-brood larvae to begin 

 hatching about August 20. 



MISCELLANEOUS OBSERVATIONS. 

 BAND RECORDS. 



A band record is an important aid in tracing the seasonal history 

 of the codling moth. The band record for 1907 is given in Table XXX 

 and is shown graphically in figure 2.

The gap between the first-brood and the second-brood larvae, 

 indicated in the 1907 band record at July 1, should have come a week 

 or more later. The week ending July 1 was cool and very rainy, the 

 bands being continuously wet. This must have delayed many 

 larvae in leaving the fruit, and prevented others from selecting the 

 bands as a place for spinning their cocoons.
