Comparative mutagenicity of two chemosterilants, tepa and hempa, in sperm of Bracon hebetor

Abstract

In an assessment of the mutagenic efficiency of the alkylating agent, tepa, and its nonalkylating analog, hempa, both chemicals induced a high frequency of recessive lethal mutations in the sperm of the parasitic wasp, Bracon hebetor Say (Habrobracon), although tepa was the more efficient mutagen.
