The Southern armyworm Spodoptera eridania (Lepidoptera: Noctuidae) is native to the American tropics and a polyphagous pest of several crops. Here we characterized a novel alphabaculovirus isolated from S. eridania, isolate Spodoptera eridania nucleopolyhedrivurus CNPSo-165 (SperNPV-CNPSo-165). SperNPV-CNPSo-165 occlusion bodies were found to be polyhedral and to contain virions with multiple nucleocapsids. The virus was lethal to S. eridania and S. albula but not to S. frugiperda. The SperNPV-CNPSo-165 genome was 137.373 bp in size with a G + C content of 42.8%. We annotated 151 ORFs with 16 ORFs unique among baculoviruses. Phylogenetic inference indicated that this virus was closely related to the most recent common ancestor of other Spodoptera-isolated viruses.

南方粘虫Spodoptera eridania（鳞翅目：夜蛾科）原产于美洲热带地区，是多种作物的多食性害虫。在这里，我们表征了一种从S. eridania分离的新型 alphabaculovirus ，分离 Spodoptera eridania nucleopolyhedrivurus CNPSo-165 (SperNPV-CNPSo-165)。发现 SperNPV-CNPSo-165 闭塞体是多面体并且包含具有多个核衣壳的病毒粒子。该病毒对S. eridania和S. albula是致命的，但对S. frugiperda不致命. SperNPV-CNPSo-165 基因组大小为 137.373 bp，G + C 含量为 42.8%。我们用杆状病毒中独特的 16 个 ORF 注释了 151 个 ORF。系统发育推断表明，该病毒与其他Spodoptera分离病毒的最近共同祖先密切相关。
