摘要: The tea slug moth Iragoidae fasciata (Lepidoptera, Eucleidae) is one of the main insect pests that attacktea bushes. A new nucleopolyhedrovirus (NPV) called Iragoidae fasciata NPV (IrfaNPV) was recently iso-lated from diseased larvae. An 11,626 bp fragment of the viral genomic DNA containing the polyhedringene and other 12 genes was cloned and sequenced. Gene comparison and phylogenetic analysis showedthat IrfaNPV is a member of the Group I NPVs. However, the genomic organization of IrfaNPV is highlydistinct. In addition, electron microscopy analysis showed that IrfaNPV is a single nucleocapsid NPV(SNPV). An inoculation assay showed that IrfaNPV is semi-permissive in the Trichoplusia ni cell lineTn-5B-4. Bioassays on lethal concentration (LCso) and lethal time (LTso) were conducted to test the sus-ceptibility of I. fasciata larvae to the virus.
