Table VIII gives a record of the feeding period of the transforming 

 larvae of the first brood (watered stock-jar method). The average 

 feeding period for male and female larvae was 24.769 days; for male 

 larvse, 23 days; female larvae, 25.142 days; maximum, male, 27 days; 

 female, 31 days; minimum, male, 21 days; female, 20 days.

Average length of feeding period, male and female larvse, 24.769 days; male, 23 days; female, 25.142 

 days. 

 Maximum length of feeding period, male and female larvse, 31 days; male, 27 days; female, 31 days. 

 Minimum length of feeding period, male and female larvae, 20 days; male, 21 days; female, 20 days. 



As shown in Table IX, the feeding period of the transforming first- 

 brood larvae (bagged-fruit method) averaged for male and female 

 25.818 days; for male larvse, 23.833 days; female larvse, 29.250 days. 

 The maximum. feeding period for male larvae was 27 days; female, 34 

 days. The minimum, feeding period for male larvae was 21 days; for 

 female, 26 days. 



By reference to Table XIX, it will be noted that the average 

 feeding period of the transforming larvse was 23.432 days.
