is a globally distributed pupal parasitoid that targets various species within the Drosophilidae family, including the invasive . The mass rearing of is a crucial step in ensuring their successful application for field control. The pupae of are currently used as a host for the mass rearing of . After irradiation, the immune system function of pupae was weakened, leading to an increase in the parasitism efficiency of the . Our results showed that irradiated pupae had a significant impact on the parasitism rate, offspring eclosion rate, offspring number, and female body size of F1 , all of which were significantly lower than those in the normal group. However, there was no significant difference in the parasitism rate, body size, offspring eclosion rate, offspring number, or offspring sex ratio between F2 emerging from treated or untreated pupae. Compared with F2, F1 had a significantly higher net reproductive rate (), mean generation time (), and doubling time (), while the intrinsic rate of increase () was significantly lower. Using irradiated pupae provides an efficient method for the mass rearing of and offers valuable insights into its potential effectiveness in field control.
是一种全球分布的蛹寄生蜂，以果蝇科中的各种物种为目标，包括入侵的 。 的大量饲养是确保其成功应用于田间 防治的关键步骤。 的蛹目前被用作大量饲养 的宿主。辐照后， 的蛹免疫系统功能减弱，导致 的寄生效率提高。我们的结果表明，辐照蛹对F1 的寄生率、后代羽化率、后代数量和雌虫体型有显著影响，所有这些均显著低于正常组。然而，来自经处理或未处理的 蛹羽化出的F2 在寄生率、体型、后代羽化率、后代数量或后代性别比方面没有显著差异。与F2相比，F1的净增殖率（ ）、平均世代时间（ ）和加倍时间（ ）显著更高，而内禀增长率（ ）显著更低。使用辐照 的蛹为 的大量饲养提供了一种有效方法，并为其在田间 防治中的潜在有效性提供了有价值的见解。
