| 摘 要： | 研究了苜蓿尺蠖核型多角体病毒AcMNPV-AaIT对甜菜夜蛾的致病力和传播流行性。结果表明:AcMNPV-AaIT对甜菜夜蛾有较高的毒力,温度对毒力有很大的影响,在17℃与23℃的条件下,LC50分别为104.56,105.92PIB/mL;感病幼虫的尸体容易腐烂流脓,且脓汁内含有大量病毒。低温贮藏对该病毒的毒力没有明显影响,说明AcMNPV-AaIT有较好的传播流行性,是一种理想的生防病毒。

| Abstract: | The pathogenicity and prevalence of AcMNPV to Spodoptera exigua was studied in the paper.The results showed that the AcMNPV-AaIT had high virulence to Spodoptera exigua.The influence of temperature on toxicity of AcMNPV-AaIT was significant.At 17℃ and 23℃,the LC50 of AcMNPV-AaIT to Spodoptera exigua larvae was 104.56 and 105.92 PIB/mL,respectively.The dead insects infected by the AcMNPV-AaIT were decayed and suppurated easily and the pus contained a mass of virus.The toxicity of AcMNPV-AaIT stored at 4 ℃ was not obviously changed.This suggested that the AcMNPV-AaIT has fairly good propagation and is a hopeful virus for biological control. |
