【目的】 明确柞蚕Antheraea pernyi灰卵（工厂化繁育赤眼蜂过程中的一种感病寄主卵）繁育的螟黄赤眼蜂Trichogramma chilonis对米蛾Corcyra cephalonica卵的寄生能力与发育适合度，为寄主卵质量控制提供依据。【方法】 以柞蚕灰卵繁育的子代赤眼蜂为处理组，健康卵繁育的子代赤眼蜂为对照组，比较两组赤眼蜂对冷藏0、1、2和3 d米蛾卵的寄生量、羽化率、发育历期和后代雌性比。【结果】 处理组赤眼蜂在冷藏0-3 d米蛾卵的寄生量显著低于对照组的寄生量（P < 0.05）。两组赤眼蜂在冷藏0 d米蛾卵的羽化率、发育历期均无显著差异（P > 0.05）；处理组在冷藏1、2和3 d米蛾卵的羽化率均显著低于对照组的羽化率（P < 0.05），而处理组在冷藏1、2和3 d米蛾卵的发育历期均显著长于对照组的发育历期（P < 0.05）。两组赤眼蜂在冷藏0和1 d米蛾卵的雌性比无显著差异（P > 0.05）；处理组在冷藏2和3 d米蛾卵的雌性比均显著高于对照组的雌性比（P < 0.05）。【结论】 柞蚕灰卵作为寄主卵会对螟黄赤眼蜂子代蜂的寄生能力与发育适合度产生一定程度的不良影响。

 [Aim]  To clarify the parasitic ability and developmental fitness of Trichogramma chilonis from the gray eggs of Antheraea pernyi on Corcyra cephalonica eggs, a host egg susceptible to bacteria during massive production of T. chilonis. This study aims to provide a basis for host egg quality control. [Methods]  Trichogramma offspring reared by the gray eggs served as the treatment group, while Trichogramma offspring reared by the healthy eggs served as the control group. The parasitism rate, emergence rate, developmental duration and female proportion of Trichogramma offspring reared by the two groups were compared on refrigerated 0-3-day-old eggs of the rice moth C. cephalonica. [Results]  The offspring reared from the control group (healthy eggs) significantly parasitized more eggs on refrigerated 0-3-day-old eggs of C. cephalonica than that from the treatment group (gray eggs) (P < 0.05). There were no significant difference in emergence rate and developmental duration on refrigerated 0-day-old eggs of C. cephalonica between the offspring reared from the two groups (P > 0.05). The emergence rate of offspring reared from the treatment group on refrigerated 1-3-day-old eggs of C. cephalonica was significantly lower than that from the control group (P < 0.05). However, the developmental duration of offspring reared from the treatment group on refrigerated 1-3-day-old eggs of C. cephalonica was significantly higher than that from the control group (P < 0.05). There was no significant difference in female proportion on refrigerated 0- or 1-day-old eggs of C. cephalonica between the offspring reared from the two groups (P > 0.05). The female proportion of offspring reared from the treatment group on refrigerated 2- or 3-day-old eggs of C. cephalonica was significantly higher than that from the control group (P < 0.05). [Conclusion]  The results indicated that the gray eggs of A. pernyi caused by bacteria could some adversely affect the parasitic ability and developmental fitness of T. chilonis.
