THE CODLING MOTH IN THE OZARKS. 31 
CONCLUSIONS. 
Three generations of larve of the codling moth occur in the Ozarks 
of northern Arkansas, and most of the members of ‘the second gen- 
eration develop into adults. 
The date at which larve begin to enter the fruit, relative to the 
blossoming of apple trees, is susceptible to great variation on account 
of weather conditions. In the two seasons under observation the 
interval was 6 and 3 weeks, respectively, between the falling of 
apple blossoms and the hatching of the first larve. 
There is a sufficient interval between the first brood and the sec- 
ond brood of larve to be noticeable in the field; so that members 
of the two broods, though present together, may be distinguished 
by their size in most cases. 
The third brood of larve constitutes the greater part of the winter- 
ing brood. Since the principal varieties of apples are harvested in 
this region while considerable numbers of the third brood of larve 
are yet immature, the number of larve wintering in the orchard is 
materially reduced. A smaller percentage of fruit is infested by the 
codling moth in this locality than in many places where only two 
generations are developed. 
A summary of the seasonal history of the insect for the year 1908, 
as detailed in the preceding pages, is shown diagrammatically in 
figure 8.
