Effect of sublethal Concentrations of parathion on the Biology of Spodoptera litura (Fabricus)
The effect of LC 30 (0.0088) and LC 50 (0.0182) of ethyl-parathion on the biology (fecundity, fertility, longevity, weight of larvae and pupae) of individuals surviving from the treatments were determined for two generations of Spodoptera litura F.
