| 摘 要： | 为了验证应用白僵菌油悬浮剂防治草原蝗虫的实际效果,为大面积推广应用提供科学依据而进行药效评价试验。结果表明:100亿孢子.mL-1球孢白僵菌油悬浮剂在2 250～3 000mL.hm-2剂量范围内对草原植被生长安全。随着用药量增加,对草原蝗虫的防效也提高。药后7d达到作用高峰,平均防效为68.24%～77.44%,后效可持续7d。推荐用量以2 250～3 000mL.hm-2为佳。

| Abstract: | The study was conducted to confirm the practical effect of beauveria bassiana SC on grassland locusts and provide scientific basis for large area application.The results showed that it was safe to steppe vegetation when using the ball spore beauveria bassiana oil SC of 10 billion spores per milliliter in the dosage range from 2 250 to 3 000 mL·hm-2.The control efficiency on grassland locust was improved by the increasing dosage.The peak effect value after using the drug 7 days,the average control efficiency was 68.24%～77.44%,and the aftereffect could last for 7 days.The recommended dosage of the drug was from 2 250 to 3 000 mL·hm-2 for better use. |
