oa Journal of the Entomological Society of Southern Africa - The influence of population densities on the development and oviposition of Plodia interpunctella HLibn. (Lepidoptera)



It is of vital importance, when breeding parasites under laboratory conditions, that wastage of material should be avoided, and that the progeny of both the host and the parasite should be healthy and fertile. Therefore the influence of population densities on development and oviposition should be studied, in order to determine the optimum density for the rearing of any species in large numbers. Population densities are also of great importance where insects are reared in laboratories to test and standardise insecticides.
