The effect of different photoperiods on food consumption, utilization and approximate digestibility of Eri silkworm (P.ricini) was carried in P. G. Madhav Vigyan Mahavidhyalay, Ujjain (M.P.). 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 food consumption, utilization and approximate digestibility by the Eri silkworm larvae were found maximum in G5 and the minimum rate was found in G2 photoperiod.
