Effect of Sexual Experience on Male Mating Success in a Lek Forming Tephritid Anastrepha Suspensa (Loew)
Abstract
Recently mated Anastrepha suspensa (Loew) males are less likely to copulate than virgin rivals when placed in competition. This effect is lost after 2 h. Mated males are as active as virgins in sexual advertising and the lack of mated male success appears to be due to female rejection. Females may be discriminating against males made relatively infertile through exhaustion of accessory gland fluids. Postcopula male unattractiveness might decrease the expected high variance in male sexual success associated with lekking species.Downloads
