24 DECIDUOUS FRUIT INSECTS AND INSECTICIDES. 
The third brood shown in the 1907 band record (beginning Sep- 
tember 2) is probably normal in bulk, though the curve should per- 
haps rise more abruptly and stop earlier at the date of harvesting 
the apples. There were taken October 7 from the bands 156 larve, 
an average of 52 per week since the last previous examination; mean- 
while the fruit had been gathered, but the exact date could not be 
ascertained. Picking the fruit would of course put an end to the 
band record. 
It will be noticed in the curve (fig. 2) that the second brood is many 
times larger than the first. But the third brood, instead of showing 
a further increase, is scarcely larger than the first. This is not to be 
taken as evidence of only a partial brood, but is due to the fact 
that the fruit was harvested before the bulk of the third brood had 
matured.

The 1908 band record (Table XX XJ and fig. 3) was influenced by 
the very smal’ size of the apple crop in that year.
