摘要
黑龙江省是我国玉米主产区,玉米螟是发生在玉米上的常见害虫,近年来,玉米螟对黑龙江省玉米的危害呈逐年加重趋势。本文在黑龙江省玉米螟重发区对甘蓝夜蛾核型多角体病毒对玉米螟防治效果进行研究,研究结果表明:20亿PIB/mL甘蓝夜蛾核型多角体病毒悬浮剂50mL/667m^2在玉米心叶末期(见雄穗率5%)1次施药防治效果与50 000IU/mg苏云金杆菌(BT)粉剂25g/667m^2在玉米心叶末期(见雄穗率5%)1次施药对玉米螟的防治效果相当,挽回产量损失率最高达10.1%,是较好的玉米螟防治微生物杀虫剂。
Heilongjiang province is one of the main a common pest occurred on maize. In recent years, longjiang has been increasing year by year. In this maize the production areas in China. Corn borer is damage of corn borer to maize in Heipaper, the prevention and control effect of MabrNPV on corn borer was studied in the worst - affected areas by corn borer in Heilongjiang Prov- ince. The results showed that the prevention and control effect of MabrNPV 2 billion PIB/mL SC at the application rate of 50mL/667m2 was equivalent the period of 5% tassel rate of maize, and that the to that of BT 50 000IU/mg DP used one time in loss recovery rate was up to 10. 1%. MabrNPV 2 billion PIB/mL SC is a good insecticide for preventing and controlling corn borer.
