96 * DECIDUOUS FRUIT INSECTS AND INSECTICIDES. 
After the loose bark had been scraped from the trunks of 16 trees, 
burlap bands were placed around the main trunk in the usual man- 
ner about 3 feet from the ground. On 5 of the trees bands were also 
placed on the main branches, so as to obtain records as to the relative 
number of larve ascending the trees from the ground from wind-fallen 
fruit, as compared with the number of larve descending from fruit 
onthe trees. The trees, with one exception, consisted of winter varie- 
ties, 10 of which were Golden Russet, 1 Northern Spy, 2 Greening, 
and 3 undetermined. Since only 16 trees of the whole orchard were 
banded, it is believed that the comparatively small number of first-

brood larvee which were removed had no influence upon the number 
of larvee of the second brood. With the appearance of the first larve, 
July 13, the banded trees were examined every three days throughout 
the season until November 13. (See fig. 21.) 
In comparing the number of larve collected from the upper and 
the lower bands, it will be noted (Table XX XIII) that 53 per cent 
were taken from the lower bands and 47 per cent from the upper 
bands. These figures are of interest as bearing on the effectiveness 
of gathering windfalls. A summary of the band records is given in 
Table XXXIV.
