姬蜂总科是地球上最多样化的动物谱系之一，有48,000个已描述物种和更多未描述的物种。这个超级家族的寄生蜂大多是攻击和杀死其他节肢动物的有益昆虫，对于了解与寄生虫相关的多样化和生活史策略的进化非常重要。此外，姬蜂总科内的一些寄生蜂谱系已经获得了内源病毒元件(EVE)，这些病毒元件永久地是黄蜂基因组的一部分，并通过宿主免疫干扰和行为控制使黄蜂受益。不幸的是，对病毒获取、寄生策略、多样化和宿主免疫破坏机制的进化的理解，由于缺乏一个强有力的肺炎总科系统发育框架而严重受限。在这里，我们设计了针对91个分类群的541个基因的探针，以测试系统发育关系、寄生蜂策略的进化，以及探针捕获不同分类群中的多聚核糖核酸病毒基因的有效性。姬蜂总科之间的系统发育关系在很大程度上得到了很好的解决，大多数较高级别的关系得到了最大程度的支持。我们注意到外群、茧蜂科和姬蜂科之间以及蜂亚科内部密码子的使用偏向，这在很大程度上是通过分析氨基酸而不是核苷酸数据来解决的。这些偏差可能会影响系统发育重建，建议谨慎进行外群选择。在分析中，蚕科的祖先状态重建是不同的，但在姬蜂科的独生体/孔雀体体重建中是一致的。这些数据表明，在整个超级家庭中，寄生蜂的生活史特征之间发生了多次转变。姬蜂科的两个亚家族都有多聚核糖核酸病毒，这为两次独立获得新冠病毒提供了强有力的证据。使用我们设计的探针捕获多聚DNA病毒只取得了部分成功，这表明需要更有针对性的方法才能使这一策略有效地调查这些病毒基因的分类群。总而言之，这些数据为肺炎总科的进化提供了一个强有力的框架。
Ichneumonoidea is one of the most diverse lineages of animals on the planet with >48,000 described species and many more undescribed. Parasitoid wasps of this superfamily are mostly beneficial insects that attack and kill other arthropods and are important for understanding diversification and the evolution of life history strategies related to parasitoidism. Further, some lineages of parasitoids within Ichneumonoidea have acquired endogenous virus elements (EVEs) that are permanently a part of the wasp’s genome and benefit the wasp through host immune disruption and behavioral control. Unfortunately, understanding the evolution of viral acquisition, parasitism strategies, diversification, and host immune disruption mechanisms, is deeply limited by the lack of a robust phylogenetic framework for Ichneumonoidea. Here we design probes targeting 541 genes across 91 taxa to test phylogenetic relationships, the evolution of parasitoid strategies, and the utility of probes to capture polydnavirus genes across a diverse array of taxa. Phylogenetic relationships among Ichneumonoidea were largely well resolved with most higher-level relationships maximally supported. We noted codon use biases between the outgroups, Braconidae, and Ichneumonidae and within Pimplinae, which were largely solved through analyses of amino acids rather than nucleotide data. These biases may impact phylogenetic reconstruction and caution for outgroup selection is recommended. Ancestral state reconstructions were variable for Braconidae across analyses, but consistent for reconstruction of idiobiosis/koinobiosis in Ichneumonidae. The data suggest many transitions between parasitoid life history traits across the whole superfamily. The two subfamilies within Ichneumonidae that have polydnaviruses are supported as distantly related, providing strong evidence for two independent acquisitions of ichnoviruses. Polydnavirus capture using our designed probes was only partially successful and suggests that more targeted approaches would be needed for this strategy to be effective for surveying taxa for these viral genes. In total, these data provide a robust framework for the evolution of Ichneumonoidea.
