Parasitoids forage for hosts in dynamic ecosystems and generally have a short period of time to access hosts. The current study examined the optimal reproductive attributes of two egg parasitoids, Dodd (Hymenoptera: Platygastridae) and Ishii (Hymenoptera: Encyrtidae), of the kudzu bug, Fabricius (Hemiptera: Plataspidae). The proportion of and adult offspring that emerged from eggs and the sex ratio of the parasitoid offspring were compared among treatments for the effects of different adult parasitoid food sources, host egg-to-adult parasitoid ratios, and host exposure times. Our results suggest that honey solution as a food source, a 21:7 host-to-parasitoid ratio, and three-to-five days of exposure time optimized the production of female . For , honey solution as a food source, a 21:7 host-to-parasitoid ratio, and one day were optimal for maximizing female offspring production. These findings provide new information about the biology of these egg parasitoids.
寄生蜂在动态生态系统中搜寻寄主，通常只有很短的时间来找到寄主。当前研究考察了葛藤蝽（半翅目：盾蝽科）的两种卵寄生蜂，多德氏寄生蜂（膜翅目：宽盾蝽科）和石井氏寄生蜂（膜翅目：跳小蜂科）的最佳繁殖特性。在不同的成年寄生蜂食物来源、寄主卵与成年寄生蜂比例以及寄主暴露时间的处理中，比较了从卵中羽化出的多德氏寄生蜂和石井氏寄生蜂成年后代的比例以及寄生蜂后代的性别比。我们的结果表明，以蜂蜜溶液作为食物来源、寄主与寄生蜂比例为21:7以及暴露三到五天，可使多德氏寄生蜂雌性后代的产量达到最优。对于石井氏寄生蜂而言，以蜂蜜溶液作为食物来源、寄主与寄生蜂比例为21:7以及暴露一天，最有利于雌性后代产量的最大化。这些发现为这些卵寄生蜂的生物学特性提供了新信息。
