The sexual difference in haemolymph protein of four insects was studied by means of an improved disc-electrophoresis (discontinuous electrophoresis) on acrylamide gels. The heamolymph was obtained from the larvae and pupae of the silkworm, Bombyx mori L., the larvae of the rice stem borer, Chilo suppressalis WALKER, the adults of the American cockroach, Periplaneta americana L. and the house fly, Musca domestica L. Sexual difference in silkworm haemolymph protein was detected at the middle stage of the fifth larval instar and also in the pupal stage. Similar sexual difference was found in the haemolmph in the rice stem borer, the American cockroach and the house fly. In order to elucidate whether the testis and ovary have some influences on the silkworm haemolymph protein pattarns in either sex, they were either implanted or castrated in the early stage of the fifth larval instar. The reults indicated that the testis and ovary, in general, have no relation with the sex-specific component of larval haemolymph protein. It was found, however, that the castration of ovaries from the females of the KL strain induced a change in the haemolymph protein paterns at the middle pupal stage.
