The host range of insect parasitoids and herbivores is influenced by both preference-related traits which mediate host choice behaviour, and performance-related traits which mediate the physiological suitability of the consumer-resource interaction. In a previous study, we characterised the influence of preference- and performance-related traits on the host range of the aphid parasitoid Binodoxys communis (Hymenoptera: Braconidae) and herein we build upon those data sets by mapping a series of these traits onto the phylogeny of the (aphid) host species. We found a strong effect of host phylogeny on overall parasitoid reproduction on the 20 host species tested, but no effect of the phylogeny of host plants of the aphids. We found an effect of aphid phylogeny on host acceptance and sting rates (related to preference) from behavioural observations and for pupal survivorship (related to performance), showing that both classes of traits show phylogenetic conservatism with respect to host species.
昆虫寄生蜂和草食性动物的宿主范围受到偏好相关特征和性能相关特征的影响，前者介导宿主选择行为，后者则介导消费者-资源相互作用的生理适宜性。在之前的一项研究中，我们研究了偏好相关特征和性能相关特征对蚜虫寄生蜂双叉室茧蜂（膜翅目：长尾小蜂科）宿主范围的影响，本研究在此基础上，将一系列特征映射到（蚜虫）宿主物种的系统发育树上。我们发现，在测试的 20 种宿主物种中，宿主的系统发育对寄生蜂的整体繁殖有很强的影响，但蚜虫的宿主植物系统发育没有影响。我们发现，蚜虫的系统发育对行为观察的宿主接受率和蜇刺率（与偏好有关）以及蛹存活率（与性能有关）有影响，这表明这两类特征在宿主物种方面都具有系统发育保守性。
