摘要：自 1956年从赤松毛虫Dendrolimusspectabilis上首次发现赤松毛虫质型多角体病毒 1型 (D .spectabiliscytovirus 1,DsCPV 1)以来 ,先后从马尾松毛虫D .punctatus、油松毛虫D .tabulaeformis、赤松毛虫、德昌松毛虫D .p .tehchangensis、文山松毛虫D .p .wenshangensis和落叶松毛虫D .superans上发现了质型多角体病毒 (cytoplasmicpolyhedrosisvirus ,CPV)。病毒基因组dsRNA电泳图谱分析表明 ,这些松毛虫CPV的不同分离株均属于质型多角体病毒 1型 (cytovirus 1)。这些松毛虫CPV病毒可以感染鳞翅目 10科 3 5种昆虫 ,其中对多种昆虫具有很高的感染力和良好的杀虫效果 ,可以从中筛选替代宿主生产松毛虫CPV杀虫剂 ,用于害虫生物防治。松毛虫CPV接种某些昆虫后病毒的基因组dsRNA电泳图谱发生了改变 。
Since DsCPV-1 (Dendrolimus spectabilis cytovirus 1) was discovered and sep arated fr om Dendrolimus spectabilis in 1965 in Japan, there have been 6 isolates of c ytoplasmic polyhedrosis virus separated respectively from D. punctatus, D. tab ulaeformis, D. spectabilis, D. p.tehchangensis, D. p. wenshangensis and D. s uperans in China. Electrophoretic analysis of the genome dsRNA of these CPV is olates showed that they all should be classified into the cytovirus 1 as the DsC PV-1. These Dendrolimus spp. CPV isolates can infect 35 species of insects in 10 famili es of Lepidoptera and have a well infectious ability and cause high mortality on many of them, so they also could be used in the control and these insects could be used as candidates for alternate hosts to produce Dendrolimus spp. CPV p esticides. The genome profiles of the viruses obtained from some insects infecte d by these Dendrolimus spp. CPV isolates are different from that of the inoc ulants, but related closely, if not identical, to viruses from these insects. These ma y be explained as that the occult viruses of hosts were activated by other virus es.
