| 摘 要： | 1982年在京郊从甘蓝夜蛾虫体上分离到一株核型多角体病毒一“京农8217”株。多角体直径0.87～2.25微米,病毒粒子平均长250纳米,为多粒包埋型。凝集试验表明:与黑龙江分离的MbNPV之间凝集滴度有4倍以上差别,补结试验表明:与单粒包埋的HaNPV无抗原交叉。交叉感染试验结果:对甘蓝夜蛾、棉铃虫、烟青虫的LC_(50)无显著差异。防治菜田及棉田棉铃虫均有70％左右效果。

| Abstract: | A nuclear polyhedrosis virus, "JN8217", was isolated from cabbage moth, Mamestrs brassicae. Electron microacopy studies revesled that the virona were muticapaid; 250nm in average length and were embeded in polyhedrons ranging from 0.87um to 2.25um. Complement fixation test showed that there ware no crosa-reacting nuclear polyhedrosis virua of Haliothis assults. Agglutination teat indicated that the titre ratio of MbNPV-JN8217 to MbNPV isolated in Heilongjiang was four. The LC50 of MbNPV-6217 against Mamestra brassicae.H. armigera and H. assulta was almost equal. When the virus was aprayed in cotton and vegetable fields, the mortality of H. assults were 70%. |
