Chemosterilant Studies on Bracon (Hymenoptera: Braconidae) Sperm. I. Sperm Inactivation and Dominant Lethal Mutations

Abstract
Eight chemosterilants were investigated to determine whether they produced sterility by the induction of dominant lethal mutations, sperm inactivation, or both. Although the compounds varied considerably in effectiveness as sterilizers, all produced dominant lethal mutations in the sperm. Tretamine and metepa produced complete sterility without any evidence of sperm inactivation. Such chemosterilants as tepa and its analogs produced significant amounts of sperm inactivation.
