1.灰腹果蝇Asobara tabida是果蝇幼虫在发酵基质中的寄生蜂。因为它是一个广泛分布的物种，它可能会遇到不同的生物和非生物环境中的不同部分的范围。寄主种群的种类组成随寄生蜂活动区的不同而不同。暗色类群物种（尤其是暗色类群）。subobscura）是西北和中欧拟寄生蜂的主要寄主;黑腹蜂是南欧寄生蜂的主要寄主.黑腹果蝇幼虫能抵御A. tabida通过包裹卵而存活。melanogaster始终低于D. subobscura。来自南欧种群的寄生蜂在D.melanogaster中的生存能力比它们在西北和中欧的同种寄生蜂要好得多;来自不同种群的寄生蜂在D. subobscura中的生存能力同样很好。D.黑腹果蝇的寄生蜂比黑腹果蝇的寄生蜂更大，这可能部分地补偿了黑腹果蝇的寄生蜂。subobscura.在种群内，较大的A.雌燕的卵巢管里有更多的卵。此外，南欧女性比北方和西欧/中欧女性有更多的卵子和更少的脂肪。大小和寿命之间的关系是模糊的。7.它的结论是，寄生蜂从不同的人口是适应特定区域的情况。
1. Asobara tabida is a parasitoid of Drosophila larvae in fermenting substrates. Because it is a widespread species, it may encounter different biotic and abiotic circumstances in various parts of its range.2. The species composition of the host population varies over the parasitoid's range: D. obscura-group species (especially D. subobscura) are the main hosts for northwestern and central European parasitoids; D. melanogaster is the main host for southern European parasitoids.3. D.melanogaster larvae can defend themselves against A. tabida by encapsulating the parasitoid egg, and survival in D. melanogaster is always lower than in D.subobscura.4. Parasitoids from southern European populations are much better able to survive in D.melanogaster than their northwestern and central European conspecifics; parasitoids from different populations are equally well able to survive in D.subobscura.5. The lower survival in D. melanogaster may be partly compensated for by the larger size of parasitoids emerging from this host species compared to parasitoids emerging from D. subobscura.6. Within population groups, larger A. tabida females have more eggs in their ovarioles. Additionally, southern European females have more eggs and less fat than northern and western/central European females. The relationship between size and longevity is ambiguous.7. It is concluded that parasitoids from different populations are adapted to region-specific circumstances.
