[Vitellogenic protein in a male environment in the silkworm, Bombyx mori L. (Lepidoptera): attempts to obtain experimentally a normal vitellus].
An ovary, implanted in a male silkworm of the same age shows an abnormal vitellus, deprived of the principal vitello-protein. The amino-acid retention due to the removal of sericiglands does not lead to a normal vitellogenesis. On the contrary, the injection of an eggs extract allows the formation of eggs with a normal vitellus. Without this process, in male hemolymph, the vitello-protein did not reach the threshold necessary to be absorbed by the ovary.
