abstract
UV Protectant is a very sensitive factor which affect the NPV working on larvae. Both activated charcoal and metallic aluminum suppressed the impact of UV radiation on NPV. However the extent of protection was different particularly, when the NPV solution was exposed for more than 10 minutes. The differential impact of protection was not prominent at less exposure time (i. e. 5 min.) This may be due to the non – significant effect of UV on virulency of NPV at less exposure period. The main aim of this review paper is to provide the knowledge of less effect of NPV on pest due to UV radiation.
