Abstract
The effect of different photoperiods on longevity of male and female of Eri silkworm (P.ricini) was carried in P.G. Madhav Vigyan Mahavidhyalay, Ujjain (MP). The Eri silkworms reared under the exposure of different experimental photoperiods G1 (12L:12D),G2 (LL), G3 (10L:14D), G4 (08L;16D), G5 (05L:19D) and G6 (DD), at temperature (25±2ºC) and relative humidity (75±5%).The longevity of male and female moths were maximum in G3 and minimum in G2, complete light.
