Abstract：
:Thiotepa and its oxygen analogue tepa, used to chemosterilize males of Culex pipiens fatigans for genetic control purposes, are toxic and mutagenic. An investigation showed that adult mosquitos that had been treated as pupae showed no detectable chemosterilant in their tissue 24 hours after emergence from the pupal stage.
