Helicoverpa armigera (Hübner) is a polyphagous and cosmopolitan pest inflicting annual crop losses worth US $ 1 billion. Here, we aimed at studying the genetic diversity of pod borer using random primers. Thirteen random primers generated a total of total of 150 amplicons with an average of 11.53 bands per primer. There were a total of 138 polymorphic bands (average of 10.61 bands per primer) with polymorphism ranging from 66.6 to 100%. The similarity coefficient values ranged from 0.13 to 0.42. UPGMA based dendrogram revealed the presence of two principal clusters which were further subdivided into 12 sub-clusters. The most striking inference of our study was that larval populations collected in the presence of multiple hosts were hyper diverse forming a separate cluster clearly distinct from populations collected on sole chickpea.
