Abstract:

Viruses from several families may cause epizootics of insects in natron, they are key factors that adjust the density of insect populations. As there are several advantages for insect viruses as bioinsecticides, such as safe for human being and environment, no resistance for insect to virus, and control pest insects for long term, etc. , they are widely and deeply studied around tile world. Here we review recent progresses in the development of wild-type virus as insecticides, the development and bio-safety assessment of genetically modified baculoviruses and new techniques of application of insect viruses in China.

Key words: viral insecticide , genetically modified virus , bio-safety , application technique
