An insect virus is a virus that causes insect diseases. The use of insect viruses to control pests, with high specificity, strong diffusion, lasting effect, harmless to humans and animals, do not pollute the environment, can effectively control pests of agriculture, forestry, tea, fruit and vegetables, and can eliminate chemical insecticide Pollution caused by agents. First, insect viruses and host symptoms caused by insect disease virus of about 650 species, the virus particles in the host cells often embedded in the protein to form inclusion bodies, according to the presence and location of inclusion bodies can be divided into Four types, namely, the nuclear polyhedrosis virus, cytoplasmic polyhedrosis virus, granulovirus, non-inclusion body virus.
