Abstract

An endogenous control of timing of many events like oviposition, eclosion, and hatching occurs at a particular time of the day, which enhances the survival of an organism. The present study is an attempt to understand the effect of different light regimes on eclosion rhythm of Drosophila agumbensis and Drosophila nagarholensis. The eclosion rhythm of the two species were analyzed under constant conditions such as continuous light (LL), continuous dark (DD), and 12-h light and 12-h dark condition. Eclosion occurred only during morning period. The peak of eclosion was observed during 10 h in the morning in all the three light regimes of both the species in 10th and 20th generation. Analysis of variance revealed that there is a significant difference in the eclosion between light/dark, DD, and LL condition and Student t test revealed that there is no significant difference between the two species.
