Abstract

Life-table and intrinsic rate of natural increase of Goniozus nephantidis was studied on three lepidopteran host insects viz. Opisina arenosella, Corcyra cephalonica and Galleria mellnonella underlaboratory conditions. Highest net reproductive rate (R0) was obtained on C. cephalanica (42.6 females/female) followed by O. arenosella (38.2) and G. mellonella (28.8). The intrinsic rate of increase (Tc) and weekly multiplication rates were also highest on C. cephalonica followed by O. arenosella and G. mellonella.
