呼伦贝尔地区油菜小菜蛾现代生物防控应用研究

Study on Application of Modern Biological Control of Rape Plutella xylostella L. in Hulun Buir Area

采用3种生物防治方法即赤眼蜂防治法、携带小菜蛾病毒的赤眼蜂防治法、小菜蛾颗粒病毒+新奥霉素防治法进行油菜大田小菜蛾的生物防治成效评估,结果表明:3种防治方法与空白对照相比,油菜产量都有提高,其中小菜蛾颗粒病毒+新奥霉素的效果最好。由此可见,生物防治方法在小菜蛾防控方面有较好的应用前景。

This experiment used three biological control methods including Trichogramma prevention treatment,carrying virus of diamondback moth Tr/chogramma prevention treatment, Plutella xylostella granulosis virus＋New Austrian mycin prevention law in rape PluteUa xylostella L. field to evaluate the biological control effect.The results showed that the yield of rape was increased by three control methods compared with the control. The effect of the virus＋New Austrian mycin was the best.It could be seen that biological control methods in the prevention and control of a small moth would have a good application prospect.
