【摘要】 采用小滴饮下法 ,研究了基因重组核型多角体病毒AcMNPVAaIT和野生型核型多角体病毒AcMNPV -C6对东方粘虫(Pseudaletiaseparata)的病原性 ,并添加感染增效物质 ,研究其增效作用。结果表明 ,AcMNPVAaIT比AcMNPV -C6具有更强的病原性 ,被感染昆虫死亡率高、致死时间短 ;添加的感染增效物质Fluorescentbrightener28具有较强的感染增效作用更多还原

【Abstract】 The pathogenicity of recombinant Pseudaletia separata multiple nucleopolyhedrovirus-Fluorescent Brightener(BR)larvae was studied with the modified droplet feeding method.The infection enhancer was added in the droplet to study the enhancing mortality of the AcMNPV.The results showed that the insects treated with AcMNPVAaIT had higher lethal ratio and shorter lethal time,that AcMNPVAaIT had stronger pathogenicity than AcMNPV-C6.The added infection enhancer BR had strong infection enhancing function.更多还原
