Phenotypic plasticity is the capability of a genotype to produce different phenotypes in different environments. The effects of changes in ambient temperature on reproductive fitness traits such as mating latency, copulation duration and mating success were studied in the Mysore and Ahmedabad populations of Phorticella striata at four ambient temperatures: - 15℃, 22℃, 29℃ and 36℃. Between the two populations the difference in mating latency was insignificant. However, the difference in copulation duration was significant between the two strains. The differences in mating latency and copulation duration at the four temperatures were also significant. Both populations exhibited long mating latency and short copulation duration at 15℃ and short mating latency, long copulation duration at 22℃ and 29℃. At 36℃ flies did not mate at all. The greatest mating success (%) was observed at 22℃ in both the Mysore and Ahmedabad populations. At 15℃, and 29℃ mating success was low. Chi-square test showed that the difference in mating success between the two populations was insignificant at different temperatures. Mating latency, copulation duration and mating success are independent events in the sexual process. These traits need not be expressed similarly by the same species under different situations. Thus, the present study heralds the phenotypic plasticity of sexual behavioral traits under various ambient temperatures. Our findings strengthen the support for the adaptive nature of temperature - mediated plasticity in sexual behavior.
