昆虫寄生蜂和草食动物的寄主范围受到两种偏好相关性状的影响，即介导寄主选择行为的偏好相关性状和介导消费者-资源相互作用的生理适宜性的性能相关性状。在以前的研究中，我们的特点的偏好和性能相关的性状对蚜虫寄生蜂Binodoxys communis的主机范围的影响（Hyattera：茧蜂科），在这里，我们建立在这些数据集的基础上，通过映射一系列的这些特性到（蚜虫）的寄主物种的生殖。我们发现宿主系统发育对测试的20种宿主上寄生蜂的总体繁殖有很强的影响，但蚜虫宿主植物的系统发育没有影响。我们发现了蚜虫寄生虫的影响，从行为观察和蛹存活率（相关性能）的主机接受和刺痛率（相关偏好），这两类性状显示相对于宿主物种的系统发育保守性。
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.
