Table 1 Effect of non-competitive context (Exp. 1 and 2) and competitive context (Exp. 3) by C. marginiventris and M. rufiventris wasps on the mean number (± SE) lifetime parasitization, female % of total progeny and remaining mature eggs in the oviducts, when 180 S. littoralis larvae (60/instar) introduced to mated females of each of Exp. 1, Exp. 2 and Exp. 3

From: Host-instar selection, interspecific competition, and reproductive capacity of extant and novel parasitoids (Hymenoptera: Braconidae) on Egyptian cotton leafworm
