| description | Chemical pesticides significantly reduce agricultural losses but pose
environmental hazards. Their effectiveness are threatened by
increasing insect resistance and unwanted destruction of non-target
organisms. Nucleopolyhedroviruses (NPVs) are getting wide attention
as an alternative and biorational method to control insect pests. In
this study, infectivity of a locally isolated NPV to control the
polyphagous pest Spodoptera litura (Fabricius) (Lepidoptera:
Noctuidae) was examined. The effects of different environmental
factors such as pH, temperature, sunlight and ultraviolet lights (UVA,
UV-B and UV-C) on the infectivity of the virus were studied.
Capabilities of different materials to protect the virus from deleterious
effects of UV and sunlight were evaluated. The virus was formulated
with different protectant materials and the effectiveness of different
virus formulations at practical field level with single and multiple
applications to control S. litura were investigated. |
