Abstract

Effects of some artificial diets containing pulverized silkworm pupae On the oviposition of a green lacewing, Chrysopa formosa, were studied. The pulverized silkworm pupae with honey seemed to be a good diet for the egg-laying activity of field-collected adults in the beginning of rearing, but their fecundity progressively decreased. Newly emerged adults. did. not lay eggs when fed the above diet, but they were able to lay eggs when the silkworm pupae were defatted and provided with honey. An adult female laid an average of 166.8, 110.2, 96.1, and 66.1 eggs after spending 5, 9, 9, and 11 days for the initiation of oviposition when supplied with various diets i.e. the cabbage aphid, defatted silkworm pupae with additive constituents, mixture of intact and defatted silkworm pupae with additive constituents, and defatted silkworm pupae with honey, respectively.
