| 摘 要： | 分别用５种浓度的八字地老虎核型多角体病毒（Ｘｃ－ｎＮＰＶ）悬液接种２龄八字地老虎幼虫和２龄甘蓝夜蛾幼虫。结果表示,两者的ＬＧ_（５０）和 ＬＴ_（５０）相差不大,可见Ｘｃ－ｎＮＰＶ对两者的毒力和潜伏期相当。用感染Ｘｃ－ｎＮＰＶ后致死的甘蓝夜蛾幼虫体内分离的病毒回接２龄八字地老虎幼虫,发现这一病毒对八字地老虎幼虫的毒力不高。

| Abstract: | Biossay of five concentration of Xc-nNPV with 2nd instar larvae of spotted cutworm and cabbage moth showed there was no significent defference of LC_(50) and LT_(50) between them. It indicated the pathogenicity and incubation period against the two pestinsects were much the same. Virus reisolated from diseased cabbage mth treated with Xc-nNPV wasess toxic to 2nd instar larvae of spotted cutworm. |
