Phylogenetic classification of Helicoverpa armigera Nucleopolyhedrovirus (HaNPV), isolated from Tobacco fields in the north of Iran, using RAPD markers

Document Type : Short Article

Abstract

For screening Helicoverpa armigera Nucleopolyhedrovirus (HaNPV) isolated from tobacco fileds of Mazandaran and Golestan Provinces in northern Iran, out of 10 Operon RAPD primers (10-mer) that randomly selected, two primers (OPM-03 and OPM-16) which showed the highest polymorphism were selected. Phylogenetic analysis was done using PyElph software and UPGMA method. Then, phylogenetic tree and genetic distances table were drawn. The cluster analysis divides the 16 HaNPV isolates into five distinct groups.  Such screening of HaNPV isolates is useful for improving biological control measures against tobacco budworm and cotton bollworm on different crops.
