Abstract
Male tobacco budworm moths, Heliothis virescens (F.), treated topically with 20 g of thiotepa or 50 g of bisazir, were effectively sterilized, and they mated as often as untreated males. Although chemosterilized males and untreated males transferred sperm equally well, the females that mated with chemosterilized males laid fewer eggs than did those that mated with untreated males. Thiotepa-sterilized males competed with untreated males for females only when they were present in equal numbers; bisazir-sterilized males competed with untreated males at ratios of 1:1, 2:1, and 3:1.
