摘要

Drosophila ananassae, a cosmopolitan and domestic species, belongs to the ananassae subgroup of the melano- gaster species group. Female remating was observed in ten mass culture stocks of this species, which were initiated from flies collected from different geographic localities. The frequency of female remaing ranges from 24 /100 to 56 /100 in different strains. Strins show significant variation in rematinglatency (days). Significant variation has also been found in all the stocks for duration of copulation between first and second matings. The duration of copulation is shorter in second mating as compared to first mating in D. ananassae.
