October, '13] HEADLEE: CODLING MOTH BROODS 395 



Actual Number of Broods 



In Fig. 7, the succession of each stage of the insect is graphically set 

 forth. Three separate and distinct emergences of adult moths are 

 shown. Three definite egg-laying periods are indicated. Three dis- 

 tinct pupation periods are set forth. Two distinct larval emergences 

 are charted. Thus it appears that in 1912, in the course of the outdoor 

 tree-cage studies at Manhattan, three distinct and successive appear- 

 ances of each of the codling moth's stages, except of larval emergence, 

 were determined. The third emergence of codling moth larvse would 

 come during late September and October. In view of the fact that lar- 

 vae emerging during late September and October in 1911, pupated and 

 produced moths in the spring of 1912, it seems entirely likely that 

 these larvse of the third brood matured, emerged, hibernated, pupated, 

 and produced moths in the spring of 1913. 



The fact that only 48 per cent of the larvse of the second brood pu- 

 pated this season, shows that the third brood is only partial. 



That the record obtained from cage breeding sets forth substantially 

 what happened in the field is shown by the close correspondence be- 

 tween pupation, moth emergence, and larval emergence curves derived 

 from the cages and from field records as illustrated in Figs. 8, 9, and 10. 



That the two full and a partial third brood cycle is not confined to 

 the year 1912 is shown by the fact that the moth emergence for 1910 

 clearly indicated three broods. 



The failure of the curves of larval emergence derived from band 

 records to indicate a third brood for the years 1910 and 1911 is due to 

 the fact that the late second brood so overlaps the small third brood as 

 to cause the collection to grade steadily down to the end, while the same 

 phenomenon in 1912 is due to the fact that the data for late September 

 and October are not available to the writer. 



Therefore, it seems very likely that the codling moth normally ex- 

 periences two full broods and a partial third at Manhattan, Kansas.
