A broad survey was undertaken to characterise microbes associated with larval outbreaks of the Antler moth Cerapteryx graminis in Cumbria, United Kingdom. A nucleopolyhedrovirus present in all sampled populations at ≤5% prevalence, was characterised via restriction fragment length polymorphism and partial sequencing the Polyhedrin, Lef-8 and Lef-9 genes; indicating a previously uncharacterised species most closely related to Agrotis ipsilon NPV. A survey of the host-associated bacterial community detected a species phylogenetically related to Spiroplasma sp., a male-killing phenotype previously isolated from Lepidoptera and Coleoptera, present at <63% prevalence in larvae. The implications of these associated microbes for host population dynamics are discussed.
开展了一项广泛的调查，以描述与英国坎布里亚地区 Antler 蛾 Cerapteryx graminis 幼虫爆发相关的微生物。在所有抽样种群中以≤5%的流行率存在的一种核多角体病毒，通过限制片段长度多态性和部分测序多角体蛋白、Lef-8 和 Lef-9 基因进行了特征描述；表明这是一种以前未被描述的与 Agrotis ipsilon NPV 关系最密切的物种。对宿主相关细菌群落的调查检测到一种与 Spiroplasma sp.在系统发育上相关的物种，这种物种以前从鳞翅目和鞘翅目昆虫中分离出来，是一种雄性致死表型，在幼虫中存在的比例<63%。讨论了这些相关微生物对宿主种群动态的影响。
