翅表型多态性是昆虫中常见的现象，但环境因素对翅表型发育或表达的影响却知之甚少。在这里，我们报告如何生物和非生物因素影响翅形态分化的bethylid寄生蜂蛹硬皮蝇。在20 °C ~ 30 °C范围内，有翅雌蜂子代的百分率随温度的升高呈指数增加。低强度光和短日照条件也显着诱导翅型的发展。有趣的是，无翅的母体寄生蜂产生更多的有翅后代。此外，翅膀二型性的程度显着影响的光强度和母亲的翅膀形态之间的相互作用。有翅雌蜂子代的百分率不受寄主密度的显著影响，但随寄生蜂卵量的增加而显著增加。而雄蜂子代的比例则随母体寄生蜂密度的增加而显著增加。我们的研究结果突出了寄生蜂S翅形态和发育的表型划分。蛹在不同的环境线索，并揭示了最有利的条件下生产的有翅的女性在这bethylid黄蜂。因此，有可能通过操纵生物和非生物条件来增加有翅雌性寄生蜂的生产，以达到生物防治的目的。
Wing phenotype polymorphism is commonly observed in insects, yet little is known about the influence of environmental cues on the development or expression of the alternative phenotypes. Here, we report how both biotic and abiotic factors affect the wing morph differentiation of a bethylid parasitoid Sclerodermus pupariae. The percentage of winged female parasitoid progeny increased exponentially with temperature between 20 °C to 30 °C. Low intensity light and short-day photoperiod conditions also significantly induced the development of winged morphs. Interestingly, wingless maternal parasitoids produced more winged progeny. Furthermore, the degree of wing dimorphism was significantly influenced by the interactions between light intensity and maternal wing morphs. The percentage of winged female progeny was not significantly influenced by foundress densities, but increased significantly with parasitoid brood sizes. However, the percentage of male progeny increased significantly with the densities of maternal parasitoids. Our findings highlight the phenotypic partitioning of wing morphology and development in the parasitoid S. pupariae under varied environmental cues, and reveal the most favourable conditions for the production of winged females in this bethylid wasp. It is thus possible to increase winged female parasitoid production for the purposes of biological control by manipulation of biotic and abiotic conditions.
