Abstract Muscidifurax raptorellus is a parasitoid wasp which is commonly used in the biological control of harmful dipterans in stables. In this study, the adaptation of M. raptorellus to different species of dipteran hosts—detrimental to both agriculture (Diptera: Tephritidae) and livestock (Diptera: Muscidae)—as well as several quality parameters of this commercial parasitoid was assessed under laboratory conditions. Our results showed a higherparasitism rate of M. raptorellus onmuscidthan ontephritid hosts and a significant effect of the natal host on M. raptorellus female longevity and fertility; however, despite this and the innate preference formuscid hosts, M. raptorellus showed similar fecundity, fertility and sex ratios when reared on pupae of Ceratitis capitata and on muscidpupae. Furthermore, both fertility and the sex ratio of commercially available M. raptorellus individuals showed values within an acceptable range of quality. Our results suggest that M. raptorellus could be recommended as a natural enemy in biological control programmes against dipteran pests harmful both to livestock and cultivated plants.

Muscidifurax raptorellus (Hymenoptera: Pteromalidae) 对家畜和栽培植物有害的双翅目害虫的质量参数和适应性

摘要 Muscidifurax raptorellus 是一种寄生蜂，常用于马厩中有害双翅目昆虫的生物防治。在这项研究中，M. raptorellus 对不同种类的双翅目宿主的适应性——对农业（双翅目：实蝇科）和牲畜（双翅目：蝇科）——以及这种商业寄生蜂的几个质量参数都在实验室条件下进行了评估。我们的结果表明，M. raptorellus 在muscidth 宿主上的寄生率高于 ontephritid 宿主，并且出生宿主对 M. raptorellus 雌性的寿命和生育能力有显着影响；然而，尽管有这种和对粘虫宿主的先天偏爱，当用 Ceratitis capitalta 的蛹和 muscidpupae 饲养时，M. raptorellus 显示出相似的繁殖力、生育力和性别比。此外，市售 M. raptorellus 个体的生育力和性别比均显示在可接受的质量范围内。我们的研究结果表明，M. raptorellus 可以被推荐为生物控制计划中的天敌，用于对抗对牲畜和栽培植物有害的双翅目害虫。
