Fig. 14. Effect of starvation on receptivity of N. cinerea following 
parturition. Solid circles — Females fed during gestation and after partu- 
rition; average days to mate after parturition was 0.7 ± 0.3. Open circles 
— Females starved during gestation, then exposed to males and food after 
parturition; 59 of 60 females mated; average days to mate after parturition 
was 2.8 ± 0.2. Open squares 0 Females starved during gestation and for 
9-10 days after parturition, then fed; average days to mate prior to feed- 
ing was 3.5 ± 0.4. First arrow = remaining females (i.e., those that did 
not mate) fed for 2 hr. only; average days to mate after feeding was 
2.0 ± 0.1. Second arrow = remaining females fed ad libitum; average 
days to mate after second feeding was 1.7 ± 0.3; 128 out of 136 females 
mated. Food was lab chow. Numerals in circles = number of insects 
(based only on females that mated). 
oocytes of the females that mated after being fed for 2 hr. and then 
ad libitum did not contain yolk so that return of receptivity could 
not be correlated with corpora allata activity using oocyte yolk as 
an indicator.
