A method for the experimental estimation of generation interval is presented together with results obtained at 25° C. for D. melanogaster Oregon-R-C maintained in population cages and in population bottles, and for D. simulans v in population bottles. Although there is significant variation between the replicate estimates obtained in population bottles, and although a number of potential sources of error have been discussed, it is suggested that this method provides useful operational estimates of the parameter, which may be taken as 23 days for D. melanogaster Oregon-R-C in population cages, 14 days for the same stock in population bottles, and 16 to 18 days for D. simulans v in population bottles.
