✦ Synopsis

Developmental time of Drosophila melanogaster was estimated for population cages with stable age distributions in a replicated experiment using 12-bottle cages. This estimate was used to fix the lower limit for 'effective generation interval' and was combined with other estimates for 8-and 12-bottle cages to estimate parameters in a negative exponential model relating effective generation interval to number of food bottles. The results indicate that for practical purposes the 'effective generation interval' becomes a constant for population cages with 4 or more bottles, assuming a uniform cycle of media replacement and a controlled environment of 23 C, and 70% R.H. This interval was estimated to be 22.5 ___ 4.9 days with 95% confidence.
