Abstract
Male Heliothis virescens (Lepidoptera: Noctuidae) were shown to transfer 36% of a whole body 65 Zn burden to the females at the time of mating. Approximately 5% of the male's and 11% of the female's total 65 Zn burdens were found in eggs oviposited during a 10-day period following mating. Transfer of zinc at mating by Heliothis males may represent the conservation of an essential trace element that must be retained throughout the life cycle.
