摘  要:
利用绿僵菌与锐劲特制备的油悬浮剂和饵剂在内蒙古草原进行了防治蝗虫试验。结果表明,利用样筐调查和扫网调查发现在施用绿僵菌油悬浮剂和饵剂后第三天蝗虫开始感病死亡,第15天死亡率显著增加,第50天死亡率超过80%,绿僵菌油悬浮剂具有比绿僵菌饵剂更好的防治效果;锐劲特油悬浮剂的杀虫速率显著高于绿僵菌,但持效性显著低于绿僵菌;锐劲特饵剂的杀虫速率和持效性居中。绿僵菌油悬浮剂可以作为防治草原蝗虫的首选生物制剂。

摘  要:
The control test to grasshopper was conducted with oil-based suspension and bait of Metarhizium anisopliae and Regent.Investigation was taken by the methods of sample and sweeping.Results showed that the grasshopper began to die in the third day after oil-based suspension and bait of M.anisopliae were applied.The mortality increased significantly in the 15th day,and the mortality exceeded 80% in the 50th day.The oil-based suspension of M.anisopliae had better control effect on grasshopper than bait of M.anisopliae.The insecticidal rate of the oil-based suspension of Regent was significantly higher than of the M.anisopliae,but the persistence was significantly lower.The insecticidal rate and persistence of Regent bait were intermediate.In conclusion,the oil-based suspension of M.anisopliae could be used as the preferred biological agents against grasshopper.
