Following the accidental introduction and spread of the invasive polyphagous agricultural pest Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), the two European egg parasitoids Anastatus bifasciatus (Geoffroy) (Hymenoptera: Eupelmidae) and Ooencyrtus telenomicida (Vassiliev) (Hymenoptera: Encyrtidae) have been investigated for inundative biological control. Since the competititve outcome between the two generalist parasitoids is difficult to predict, intrinsic competition was investigated with a time‐course development study. Both species readily oviposited in H. halys eggs containing eggs and early instar larvae of the competitor, but oviposition decreased when eggs contained late instar larvae and pupae. Ooencyrtus telenomicida offspring emergence from multiparasitized eggs was significantly lower than that from rearing controls, independent of the order of parasitization. Anastatus bifasciatus offspring emergence was not influenced by the presence of O. telenomicida when it parasitized as the first species, but emergence was decreased after oviposition in eggs containing O. telenomicida larvae and pupae. There was no indication that O. telenomicida can act as a facultative hyperparasitoid of A. bifasciatus. These results suggest that A. bifasciatus is the superior intrinsic competitor and no or minor negative implications for A. bifasciatus are expected if released in combination with O. telenomicida.

棕色mar臭臭虫的两个欧洲卵寄生虫之间的内在竞争

在意外引入并传播了入侵性多食性农业害虫Halyomorpha halys（Stål）（Hemiptera：Pentatomidae）之后，两个欧洲卵寄生寄生虫Anastatus bifasciatus（Geoffroy）（Hymenoptera：Eupelmidae）和Ooencyrtus telenomicida（Vassiliev）已进行调查以进行淹没性生物防治。由于这两个通才寄生虫之间的竞争结果难以预测，因此通过时程发展研究对内在竞争进行了研究。两种物种都容易在含有卵和竞争者的早期幼虫的H. halys卵中产卵，但是当卵中含有晚期幼虫和p时，产卵率降低。与寄生虫的顺序无关，来自多重寄生虫卵的远侧卵Ooencyrtus telenomicida的后代显着低于饲养对照者。寄生成双歧杆菌的后代的寄生时，它不会受到变形拟南芥的存在的影响，但在含有变形拟南芥幼虫和p的卵中产卵后，它们的出现会减少。没有任何迹象表明澳telenomicida可以作为兼hyperparasitoid行动A.天牛。这些结果表明，双歧曲霉是内在竞争者，对双歧曲霉没有负面影响或轻微的负面影响。如果与O. telenomicida一起释放则有望。
