was rather heavy. The drouth was accompanied by excessive heat 

 continuing until about Septeml)er. September conditions were really 

 more like June than autumn. 



The apples were not noticeably undersized in spite of the dry weather 

 perhaps because it was an "off year" for the apple crop and so no 

 trees were heavily loaded. 



In the course of the experimental work counts were made of all the 

 apples set on over one hundred trees but bands were placed on only 

 fifteen unsprayed trees in Doniphan county orchards and it was from 

 these trees that all data used here was obtained, although it was evi- 

 dent that similar conditions obtained in the other orchards. Band 

 records were not quite complete as some collections were missed during 

 August when the writer was forced to be absent from the orchards, 

 but the records from the fallen fruit show that the band records, though 

 incomplete, are not misleading. It was at first the intention to keep 

 emergence records of all larvae collected but other work interfered so 

 only pupation records were kept. In the following table the number 

 recorded as having pupated does not indicate the true percentage, as 

 most of those larvae which did not pupate, especially in the early 

 part of the season, died.

The writer's experience with the codling moth and all published 

 records from this latitude indicate that by far the greater percentage 

 of those larvae coming down from the trees after August 1st do not
