  1. The percentage of females showing true polyandry (remating after a fertile first mating), pseudopolyandry (remating after an infertile first mating) and all rematings, for flies from two populations under a variety of experimental conditions. Numbers in brackets are the actual number of females that remated. Standard conditions were females mated with a male from the same population, reared and mated at 21°C, with ample food. Note that the number of all rematings can be greater than pseudo- and true polyandry combined, as females whose mating status could not be determined were still observed to remate. The data for conditions involving starved Greek females is not shown as few mated initially (N = 8 for starved female, fed males, and N = 9 for starved females, starved males), preventing analysis of remating behaviour.
