三种生物农药防治花生蛴螬的效果比较

Comparison of the Controlling Effeciency for Suppressing Grubs in Peanut Fields Using three Biocides

本文比较了三种生物农药苏云金杆菌８０１０、绿僵菌和拟青霉菌８０８对花生蛴螬的防治效果。研究结果表明：三种生物农药对花生蛴螬的平均防效达８２．０％，其中以绿僵菌为最佳。三种生物农药能使花生产量平均增加２０％。其中以拟青霉菌为最佳。生物农药不仅能防治花生蛴螬，而且能增加花生产量。

This paper dealt with biocontrolling the peanut grubs using the three biocides, Bacillus thuringienses, Metarhizium anisopliae and Paecilomyces fumosoresens var.beijingensis.The results showed that the controlling effeciency was up to 82%on average by using the three biocides,a-mong which the M.anisopliae was the best. The yield of peanut increased up to 20%on average,in which using P.fumosoresens was the most significant.The biocide can not only control the peanut grub but also increase the peanut yield.
