| 摘 要： | 以甜菜夜蛾二龄幼虫对苜蓿银纹夜蛾核型多角体病毒（AcNPV）两种毒株采用生物测定方法进行比较。对AcNPV两毒株杀虫毒力及杀虫速率的分析表明：以甜菜夜蛾活体增殖的ACNPVA株（LD(50)=131．8PIB／头）比用草地贪夜蛾细胞株（Sf9）增殖的AcNPVB株（LD(50)=1696．8PIB／头）毒力要高10倍，而毒杀速率，也以AcNPVA株（LT(50)=4．46d）比AcNPVB株（LT(50)=6．57d）快1．5倍。

| Abstract: | The two AcNPV strains against the second instar larva of S. exiguaare compared by means of bioassay. Analysis on virulence and insect-killing rate ofthe two AcNPV strains show that in terms of virulence, LD(50) of AcNPV-A is 131.8 PIB/ILarva, LD(50) of AcNPV-B is 1696. 8 PIB/Larva,that is to say, AcNPV-Apropagated from S. exigua is 10 times as high as AcNPV-B propagated fromspodoptera frugiperda (sf9) cell in virulence; while in terms of insect-killing rate,LT(50), of AcNPV-A is 4. 46 days, LT(50) of AcNPV-B Is 6. 67 days, that's to say, theformer is 1. 5 times as fast as the latter in insect-killing rate. |
