Polyandry contributes to (Coleoptera: Curculionidae) rearing.

Background: Marelli, 1926 (Coleoptera: Curculionidae) is one of the main defoliating beetles in plantations. Biological control with egg parasitoids is one of the main control strategies for this pest and a constant supply of fresh host eggs is required to rear the parasitoids. Polyandry can influence oviposition by increasing female fecundity and fertility; however, the high density of individuals in laboratory colonies can lead to male harassment, resulting in lower reproduction rate.
