Sexual aggressiveness of male Laspeyresia pomonella(L.) was measured by comparing the longevity of female codling moths confined at various ratios with untreated males or with males treated with tepa or gamma irradiation. Females held without males lived 9.3 days, females caged at a ratio of 7 untreated males per female lived 4.2 days, and females confined at the same ratio with males treated with 40 kr of gamma irradiation or with 15 or 30 g of tepa, lived 5.1, 6.1, and 7.6 days, respectively. Also, when untreated males were caged with females at ratios of 1:1 and 7:1, the females contained 2.1 and 3.9 spermatophores, respectively; those caged at the same ratios with males treated with 15 g of tepa contained 1.7 and 4.3 spermatophores, respectively.
