In the investigations on the resources of pathogenic microorganisms of insects entomogenous fungi.Bacillus thuringiensis and nuclear polyhedrosis virus have been isolaled from the corpses of grassland caterpillar(Gymaephora spp.)in Qinghai.The inoculation experiment showed the isolated beauveris,Bacillus thuringiensis and nuclear polyhedrosis virus had the pathogenicities to their ordinary hosts on some degrees.It is possible to use the pathogens as biocontrol agents against these insect pests.
