| genetic and biological variation among nucleopolyhedrovirus isolates from the fall armyworm, spodoptera frugiperda (lepidoptera: noctuidae). | a pcr-based method was used to identify and distinguish among 40 uncharacterized nucleopolyhedrovirus (npv) isolates from larvae of the moth spodoptera frugiperda that were part of an insect virus collection. phylogenetic analysis was carried out with sequences amplified from two strongly conserved loci (polh and lef-8) from the 40 isolates in the collection and from eight previously studied s. frugiperda npv (sfmnpv) isolates. to further distinguish these isolates, analysis was also carried out ... | 2010 | 20213487 |
