摘要：
Two new Helicoverpa armigera single nucleopolyhedrovirus genotypes, HearSNPV, HearSNPV-SP1B and HearSNPV-LB6, each originating from mixtures of genotypes obtained from different locations and crops, are described. Each exhibits specific insecticidal activity against H. armigera larvae comparable to that of commonly used commercial insecticides. Further, mixing the two genotypes, especially in the ratio of 1:1, within co-occluded virions of the mixed genotypes, is capable of controlling H. armigera infestations of tomato crops and is as efficacious as commonly used chemical and biological insecticides. Their use as bioinsecticides is safe for vertebrates, in that they specifically target arthropods. In addition, they are easy to produce and good yields can be obtained by orally inoculating H. armigera larvae with HearSNPV occlusion bodies.
