摘要
600亿PIB／g棉铃虫核型多角体病毒（HeNPV）水分散粒剂是一种专业防治作物棉铃虫和烟青虫的生物药剂。试验结果表明，药后7d，600亿PIB／g棉铃虫核型多角体病毒水分散粒剂对烟青虫幼虫防治效果可达95％以上，药后10～15d，防效显著优于对照药剂甲维盐，持效期较之长3～8d。600亿PIB／g棉铃虫核型多角体病毒水分散粒剂对烟青虫具有较好的防治效果，且持效期较长，可在烟草生产上推广应用。
60 billion PIB/g Helicover- pa armigera nucleopolyhedrovirus （He- NPV） WDG was a biological agent which was specially for preventing and con- trolling Helicoverpa armigera and Helieoverpa assuha. Test results showed that the control efficacy rate of 60 billion PIB/g HeNPV WDG against H. assulta could reach up to 95% the highest 7 days after spraying, significantly superior to the control emamectin benzoate 10-15 days after application, and persis- tence of which 3-8 days longer than that of emamectin benzoate. Featuring better control efficacy, longer persistence, it could be promoted and applied on tobacco production.
