Analysis of pupation site preference in Drosophila kikkawai

Pupation site preference in Drosophila kikkawai is unique due to the fact t hat females pupate earlier and at higher level as compared to males; and th ere are significant sex differences (p<0.001) for all the seven Indian geog raphical populations. Developmental time also depicts sex specific differen ces. Such observations are contrary to the pupation site preference reporte d in other Drosophila species. Data suggest that the observed differences i n pupation site preference could be due to interaction of genotype and envi ronment affecting developmental timings of the two sexes. Thus, differences in pupation site preference may have profound repercussions on their Darwi nian fitness.
