Abstract

For virus control of insects, it is necessary to fix the minimum acquisition feeding period for the larvae to pick up infection by ingesting the polyhedra - treated food surface, before,the virus is affected by certain environmental factors. The aim of the present study was to find out the effect of acquisition feeding period in the laboratory on the mortality of Heliothis armigera (Hbn.) by nuclear polyhedrosis virus (NPV).
