Larval mortality (A) and pupal survivorship (B-C) after 0-6 days exposure to food on short day followed by continuous long day without food. Percentages after 15 days experimental time are shown by solid dots •. On day 16, duplicate experimental groups were provided a one day (Q) or a four day (O) food pulse on long day. The food was removed after this time and the larvae again placed on long day without food. Per cent larval mortality and per cent eclosion were scored on the 31st day, using the number of living, undeveloped larvae on day 16 as the sample size. Among both the one day and four day food pulsed larvae, there was a significant correlation between prior feeding ten to thirty days beforehand and larval mortality (Fig. 3A) or pupal survivorship (Fig. 3C). Development in response to a one day or a four day food pulse also appeared to be proportional to the number of days prior feeding when per cent response was calculated on the basis of the number of larvae alive at the initiation of the food pulse experiments (, the 16th day). But. if percentage development is calculated on the total number of this sample size surviving until the 31st day (n = number of living larvae + number of pupae), then development was no longer proportional to the number of days prior feeding (r — ; P > ). It would thus appear that food stored from remote feeding is capable of maintaining larval life or sustaining adult development but does not contribute to the termination of diapause in C.
