Comparison of Parasitic Behavior and Progeny Development between Winged and Wingless Female Adults of Sclerodermus pupariae（Hymenoptera: Bethylidae

【Objective】 Female adults of Sclerodermus pupariae can develop into winged or wingless morphs. However,winged females are only occasionally found in both wild and mass-reared populations. This study aims to investigate whether there are differences in the parasitic behavior and progeny development between winged and wingless female individuals, so as to provide a theoretical basis for further clarifying the necessity of inducing production of winged females in the parasitoid massrearing. 【Method】The parasitism ability, pre-oviposition period, offspring immature duration, fecundity, and male offspring proportion of winged and wingless females were measured in the laboratory conditions. 【Result】1) Both winged and wingless females could complete four times of parasitism. There was no significant difference in parasitism ability between the two types of morphs of the parasitoids, but the parasitism ability decreased with the increasing parasitism times. There was no significant difference in longevities of winged
