none Among 6 laboratory hosts tested, the egg-larval parasitoid Chelonus blackburni Cameron completed its development in only 3; Corcyra cephalonica Stainton, Phthorimaea operculella (Zeller) and Achroia grisella (Fabricius). The parasitoid failed to develop in Spodoptera litura (Fabricius), Galleria mellonella L. and Sitotroga cerealella (Olivier). The development period of the parasitoids obtained from permissive hosts correspond to the development period of their hosts. Development period of P. operculella, A. grisella and C. cephalonica were 24.7 plus or minus 2.0, 39.5 plus or minus 2.1 and 50.5 plus or minus 4.1 days respectively while the development period of the parasitoid reared from these hosts were 25.8 plus or minus 1.6, 36.4 plus or minus 3.5 and 42.5 plus or minus 3.5 days respectively. The fecundity of the parasitoids reared on A. grisella, P. operculella and C. cephalonica were 365.2 plus or minus 52.8, 287.9 plus or minus 101.9 and 248.7 plus or minus 50.8 respectively.
