摘要: 研究斜纹夜蛾核多角体病毒与增效剂混配对斜纹夜蛾幼虫的防治效果。结果表明,增效剂可以提高病毒剂的杀虫效果,每100ml病毒剂(1× 1 07PIB/ml)加入增效剂0.04g的防治效果最好。利用稀释1000倍的病毒可湿性粉剂防治银纹夜蛾、小菜粉蝶、小菜蛾幼虫,防效分别为 46.7%、60.0 %、47.2%。

Abstract: The nucleopolyhedrovirus of Spodoptera litura (SlNPV) mixed with a synergist in different proportions was studied for control S.litura under laboratory conditions Result showed that 0.04g synergist added to 100ml SlNPV suspension (1×10 7PIB/ml) was the most effective dosage for control of this pest .A wettable powder preparation of SlNPV was also used successfully to control Pieris rapae, Plutella xylostella and Argyrogramma agnata.
