Abstract

Recently obtained cypovirus strain DsCPV-1 shows potential as a biological insecticide, with its alternative host Manduca sexta (L.) being a promising producer. We confirmed DsCPV-1 replication in M. sexta by quantitative PCR, validating DsCPV-1's suitability as a biological producer. At the terminal infection stage, we revealed many nonoccluded DsCPV-1 virions by transmission electron microscopy, indicating virus replication with reduced or without polyhedron formation in this alternative host.

摘要

最近获得的质型多角体病毒株DsCPV-1显示出作为生物杀虫剂的潜力，其替代宿主烟草天蛾（Manduca sexta (L.)）是一种很有前景的生产宿主。我们通过定量PCR证实了DsCPV-1在烟草天蛾中的复制，验证了DsCPV-1作为生物生产宿主的适宜性。在终末感染阶段，我们通过透射电子显微镜观察到许多非包涵体DsCPV-1病毒粒子，表明该病毒在这种替代宿主中复制时多面体形成减少或没有形成。
