Pseudoplusia includens single nucleopolyhedrovirus: Genetic diversity, phylogeny and hypervariability of the pif-2 gene

- Genetic variation was detected among PsinSNPV field isolates.
- High genetic variation and positive selection were found in the PsinSNPV pif-2 gene.
- PsinSNPV is closely related to Chrysodeixis chalcites NPV and Trichoplusia ni SNPV.
