were liberated in their respective cages, dates when the first and the last 
larvee left the fruit, when they pupated, and when the moths emerged. 
First generation, 1915.—The first moths which emerged from hiber- 
nating larve were liberated in cage No. 1, as follows:

The first eggs were found in the cage on the morning of May 6. 
They had probably been laid during the evening of the preceding day. 
These eggs hatched May 17. There was a heavy June drop of apples 
all over the orchard and the drop was especially heavy from some of 
the trees caged. In cage No. 1, 275 apples were picked up May 20 and 
placed in battery jars. They averaged only about one-half inch in diame- 
ter. June 4, 800 were picked up, June 9, 700, June 12, 300, and June 19, 
150. At this time only a few apples remained on the tree. Larve began 
to leave the fruit in this cage June 22. 
In another cage; in which moths had been liberated on May 12, or 12 
days later than in cage No. 1, larve began to leave the fruit June 22. 
Judging from this, had normal conditions prevailed in cage No. 1, larve 
should have begun to leave the fruit 11 days earlier than they did—that 
is, on June 11. This date corresponds very well with the date when the 
first larvee were taken under bands, which was June 12. 
The last moths of the hibernating generation were liberated in cage 
No. 2, as follows:

Larve began to leave the fruit in cage No. 2 on July 6 and continued 
to leave the fruit till August 1. Pupation continued till August 4, and 
moths continued to emerge till August 17. Two larve which left the 
fruit July 17 and 19 respectively, hibernated. All other larve kept under 
observation transformed or died.
