Correlation and regression studies between pupal weight and fecundity of muga silkworm Antheraea assama Westwood (Lepidoptera: Saturniidae) on four different foodplants.
Female pupal weight and fecundity of mother moth of Antheraea assama Westwood fed with four different food plants have been studied. Litsaea polyantha fed females showed significantly higher pupal weight and higher rate of oviposition in comparison to three food plants Machilus bombycina, Litsaea salicifolia and Cinnamomum glaucescens. The number of eggs laid was correlated with the pupal weight. The correlation co-efficient (r = 0.9730) showed positive and significant correlation at 1% level. The pupal weight was found to be the best and genuine estimator of fecundity.
