none The various parameters of superparasitism were determined by exposing 50 eggs of Corcyra cephalonica (Stainton) to variable numbers of females of C. blackburni Cameron. The progenies produced were 23.5, 28.6, 11.1, 2.8, 0.6 and 0.9 in the treatments having 1, 2, 4, 6, 8 and 10 parasitoid females, respectively. The number of unparasitized hosts in the respective treatments were 18.8, 9.2, 7.6, 8.6, 8.2 and 11.0 as compared to 35.5, in the control. The number of non-viable hosts in the corresponding treatments were 7.3, 10.6, 28.9, 38.3, 39.8 and 35.8 as compared to 14.3 in the control. The incidence of parasitism vaired from 62.0 to 98.0 in the various treatments. The number of viable hosts were maximum in the control and treatment having 1 female. There was no difference in body size in the progeny resulting from 1, 2, and 4 female treatments. The longevity was studied of 1, 2, 4 and 6 female progeny and longevity was significanly gt in 1 femal treatment.
