如果杆状病毒和它们的昆虫宿主之间的关系是共同进化的，这将导致长期的进化效应，如这些病原体对其宿主的特化。为了验证这一假设，杆状病毒科的一个系统发育，包括来自鳞翅目、双翅目和膜翅目宿主的39种病毒，基于基因lef-8和ac 22的序列进行了重建。该树状图显示了杆状病毒根据其宿主的顺序的明确划分。这一划分强调了重新考虑杆状病毒分类的必要性，以包括一个或两个可能的新属。此外，不同的病毒谱系的专业化，以特定的昆虫订单表明杆状病毒和它们的主机之间的古老的共同进化的相互作用。
If the relationships between baculoviruses and their insect hosts are subject to coevolution, this should lead to long-term evolutionary effects such as the specialization of these pathogens for their hosts. To test this hypothesis, a phylogeny of the Baculoviridae, including 39 viruses from hosts of the orders Lepidoptera, Diptera, and Hymenoptera, was reconstructed based on sequences from the genes lef-8 and ac22. The tree showed a clear division of the baculoviruses according to the order of their hosts. This division highlighted the need to reconsider the classification of the baruloviruses to include one or possibly two new genera. Furthermore, the specialization of distinct virus lineages to particular insect orders suggests ancient coevolutionary interactions between baculoviruses and their hosts.
