THE CODLING MOTH IN THE OZARKS. 



19 



Forty-one third-brood larvae, hatching August 14 and reared in 

 picked fruit in jars out of doors, required from 19 to 32 days to 

 become full grown, the average being slightly over 24 days. These 

 records are given in Table XXL

All reared larvae of the third brood were of the wintering gener- 

 ation. 



WINTERING LARV^. 



A few erratic larvae maturing early in the season failed to pupate. 

 They remained in their cocoons throughout the season, apparently 

 in a perfectly healthy condition. The first of these left the fruit 

 June 9 and was undoubtedly of the first brood. Two others leaving 

 the fruit July 2 and 4 were also probably of this brood. One win- 

 tering larva left the fruit July 10, two July 19, and one August 2. 

 All the above larvae were from collected wormy fruit. Among 20 

 of the earlier second-brood larvae reared in bagged fruit (Table XXVI), 

 1 wintering larva left the fruit July 19. In 1907, out of 41 second- 

 brood larvae reared in the laboratory (Table XXIX), 5 that did 

 not pupate left the fruit August 1-6. 



Beginning August 20, the percentage of wintering larvae leaving 

 the fruit suddenly arose to include the majority. In 1907 this hap- 

 pened about the same time. A record of the material collected in 

 taking the band records at this period will illustrate the transition. 

 This is shown in Tables XXII and XXIII.
