Spotted wing drosophila, Drosophila suzukii (Matsumura), native to Asia, has become a significant threat to soft fruit crops globally. To develop a classical biological control program for this pest, the obligate parasitoid Ganaspis kimorum (Buffington) was approved in the United States for field release in 2021 as a biological control agent. However, challenges in mass production and maintenance of parasitoid colonies have been common. Here, we share improved methods and offer insights into mitigating issues that limit parasitoid production. Additionally, we present a modified rearing protocol using 2-l plastic containers to produce an average of 307 G. kimorum per container. This information is crucial for implementing successful classical biological control programs against spotted wing drosophila with this parasitoid.
铃木氏果蝇（Drosophila suzukii Matsumura）原产于亚洲，现已成为全球软果作物的重大威胁。为了针对这种害虫制定经典的生物防治方案，专性寄生蜂基氏加纳斯寄蝇（Ganaspis kimorum Buffington）于2021年在美国被批准作为生物防治剂进行田间释放。然而，寄生蜂种群的大规模生产和维持一直存在挑战。在此，我们分享改进方法，并就缓解限制寄生蜂生产的问题提供见解。此外，我们提出了一种改良的饲养方案，使用2升塑料容器，每个容器平均可生产307只基氏加纳斯寄蝇。这些信息对于利用这种寄生蜂实施针对铃木氏果蝇的成功经典生物防治方案至关重要。
