Abstract

Six strains of HaNPV collected from different places of India were compared for their biological and biochemical characteristics. Based on the bioassay tests against second and third instar larvae of Helicoverpa armigera the order of activity in increasing order is UASD-HaNPV< AK-HaNPV<TN-HaNPV<PAU-HaNPV<GAUHaNPV< ICRISAT-HaNPV and no correlation was drawn between biological and biochemical characteristics. Electron microscopic observations of polyhedra, alkali disrupted polyhedra during purification and nucleocapsids are also presented.
