16 SPRAYING PEACHES. 
Considering the results of the jarring records for the individual 
rows, the influence of the woods is very evident. A total of 476 
beetles was taken from rows 1 and 2, adjacent to woods, up to March 
23, as compared with a total of 61 beetles from the remaining eight 
rows. Fifteen days after the emergence from hibernation of the 
beetles began, namely, by March 25, their diffusion had become quite 
general all over the orchard, though the first one or two rows always 
showed on a given date a greater number of individuals than any 
other row. During the season a total of 3,197 beetles was taken 
from row 1, or 42.64 per cent of all captured. The first three rows 
adjacent to the woods gave for the season 4,813 beetles, or 64.19 per 
cent of the total for the entire plat. Between rows 9 and 10, as 
shown in the diagram, there was a terrace covered with grass and 
trash, and its influence on the abundance of the insects is also to be

noted, more individuals being taken on these respective rows than 
from any one of the rows 4 to 8, inclusive. | 
The Georgia record also shows that beetles were out in maximum 
numbers from March 25 to April 3, or about 10 days to 2 weeks 
after the trees were in bloom. During this period, 4,108 individuals 
were captured, or 54.79 per cent of the catch for the season. How- 
ever, during all of May and June the beetles were fairly abundant, 
but they diminished perceptibly during July and August. The 
increase in numbers, evident with the third week in August, is per- 
haps due to the appearance of beetles developing from ripe peaches 
or those of a second generation, for the development of which some 
evidence was obtained under laboratory conditions. Apparently all 
of the beetles had left the trees for hibernation by October 11, as after 
this date no more individuals were captured.
