After September 1 all larva appearing under bands were of the 
wintering brood. While some of the later second-brood larve may 
go over winter, there is evidence that most of them produce a second 
brood of moths instead. The species is therefore dependent largely 
upon the third-brood larve to perpetuate itself from season to 
season. 
Conditions affecting wintering larve in the orchard were not 
observed. Around the out door apple bin at a vinegar factory where 
large numbers of cocoons were examined in March and April the 
great majority of them contained live larve or pupe. 
REVIEW OF REARING WORK OF THE SEASON. 
An effort was made to rear through the season a continuous line 
of pedigreed stock from the earliest spring moths, with the principal 
object of ascertaining the maximum number of generations. With 
the exception of one unimportant break early in the season, this 
program was successfully carried out. 
The start was made from a number of eggs collected in the field 
and hatching May 4, several days before the hatching of the first 
eggs laid in cages. The larve were reared in bagged fruit on trees, 
and developed into first-brood adults as shown in Table XXIV.
