摘      要:A strain of Cytoplasmic polyhedrosis virus (CPV) was separated from the infected larva during the research of integrated pest management of Dendrolimus superans. The morphology bioassay histopathology andfield-test for this CPV were studied. The size of CPV is 0.16 μm ×1. 57μm and the virion is 16.0 nm × 58.1 *** Lc50 to the 3rd and 5th instar larva of Dendrolimus superans were 2.81 × 104 PlB/mL and 7. 17 ×104 PIB/mLrespectively. The polyhedrosis were formed after midgut of larva were infected for 72 h. A large amount of polyhedrosis was formed after 144 h. The mortality was more than 82% and average mortality was 84.62% when using1 .17× 10s PIB/mL virus suspension to control the pest in field test.
