The findings of the experiment on effect of mating duration on reproductive parameters of eri silkmoth, Samia ricini Donovan in autumn and spring season revealed that mating duration had significant effect on fecundity/female/day, total fecundity, weight of eggs/female/day, total weight of eggs and average hatchability percentage of eri silk moth. Season also had significant effect on total oviposition duration, fecundity/female/ day, total fecundity, weight of eggs/female/day, incubation period and average hatchability percentage. Interaction effect between mating duration and season was significant in total oviposition duration and weight of eggs/female/day. A period of three to five hours coupling duration was optimum for maximum egg laying of eri silk moth. Though the fecundity and weight of eggs were registered better in autumn season with shorter incubation period but hatching percentage of eggs of the silkmoth performed better in spring season.
