The data do not show the entire range of time over which beetles 
may emerge from a given locality, but they indicate about what hap- 
pens in a particular orchard. Later records could doubtless have 
been gotten had other fruits been used as a source of larvae, alter the 
gathering of the peach crop. 
The Barnesville, Ga., record is perhaps the most nearly complete, 
since at that place there is little fruit available for the curculio after 
the harvesting of Elberta peaches. This record shows an interval 
from June 6 to September 28 during which beetles were emerging — 
a period of 114 days (see fig. 21). But from larvae from some late 
seedling peaches beetles continue to emerge up to November 9, 
giving a total period ol* 156 days. Only the cold weather prevented 
still further emergence, since on November It) there still remained 
in the soil fully matured adults as well as many pupae and even a 
lew larvae. These were from a batch of 107 Larvae from seedling 
peaches, the last to be secured. The larvae left the fruit September 
18 to October L5, and L5 beetles emerged October 10 to November 
9. The soil in the box was examined November 10, when there 
were found 6 beetles ready to emerge. 28 live healthy pupae, 5 live
