Asobara japonica (Hymenoptera: Braconidae), Ganaspis brasiliensis and Leptopilina japonica (Hymenoptera: Figitidae) are Asian larval parasitoids of spotted wing drosophila, Drosophila suzukii (Diptera: Drosophilidae). This study evaluated these parasitoids’ capacity to attack and develop from 24 non-target drosophilid species. Results showed that all three parasitoids were able to parasitize host larvae of multiple non-target species in artificial diet; A. japonica developed from 19 tested host species, regardless of the phylogenetic position of the host species, L. japonica developed from 11 tested species; and G. brasiliensis developed from only four of the exposed species. Success rate of parasitism (i.e., the probability that an adult wasp successfully emerged from a parasitized host) by the two figitid parasitoids was low in hosts other than the three species in the melanogaster group (D. melanogaster, D. simulans, and D. suzukii). The failure of the figitids to develop in most of the tested host species appears to correspond with more frequent encapsulation of the parasitoids by the hosts. The results indicate that G. brasiliensis is the most host specific to D. suzukii, L. japonica attacks mainly species in the melanogaster group and A. japonica is a generalist, at least physiologically. Overall, the developmental time of the parasitoids increased with the host’s developmental time. The body size of female A. japonica (as a model species) was positively related to host size, and mature egg load of female wasps increased with female body size. We discuss the use of these parasitoids for classical biological control of D. suzukii.

Asobara japonica（膜翅目：Braconidae），Ganaspis brasiliensis和Leptopilina japonica（膜翅目：Figitidae）是斑翅果蝇亚洲果蝇的幼体寄生虫，Srosukii Drosophila suzukii（Diptera：Drosophilidae）。这项研究评估了这些寄生虫从24种非目标果蝇物种中攻击和发育的能力。结果表明，这三种寄生虫都能在人工饮食中寄生多种非靶标物种的寄主幼虫。A.粳稻从19个测试宿主物种开发的，无论宿主物种的种系发生的位置，金银花从11种测试开发; 和巴西乳杆菌仅从四个暴露物种中发展而来。除黑猩猩组中的三个物种（D. melanogaster，D。simulans和D.）以外，其他两个无花果类寄生虫对寄生虫的成功率（即成年黄蜂成功地从被寄生的寄主中出现的可能性）较低。铃木）。在大多数受试宿主物种中，无花果的发育失败似乎与宿主对寄生虫的更频繁包封相对应。结果表明，巴西橡胶菌是铃木蝇的特异寄主，粳稻的攻击物种主要是黑腹蝇组和粳稻。是一名多面手，至少在生理上是这样。总体而言，寄生虫的发育时间随着宿主的发育时间而增加。雌性日本粳稻的体型（作为模型物种）与寄主的大小呈正相关，雌性黄蜂的成熟卵负荷随雌性体型的增加而增加。我们讨论了这些寄生虫对铃木D.的经典生物控制的使用。
