Abstract: | Drosophila ananassae, a cosmopolitan and domestic species, belongs to theananassae subgroup of themelanogaster 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 remating ranges from 24% to 56% in different strains. Strains
show significant variation in remating latency (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 inD. ananassae. |
