Abstract

Current study represents the different photoperiodic effect on the moth parameter of Eri Silkworm (Philosamia ricini). During the course of study it was observed that maximum emergence of the moth was obtained  in 08 hr light and 16hr darkness which is appropriate photo period in comparison to control (normal light and dark). In the present experiment it was observed that the male moths emerged earlier than the female moth.
