摘要

为探明白僵菌是否能在自然环境对玉米螟有持续的防治效果,在吉林省西部地区对施用白僵菌封垛地区和未施用白僵菌封垛地区玉米螟死亡情况进行了系统调查。调查结果如下:因感染白僵菌致死的玉米螟在玉米螟死亡总数中占主导地位,且因白僵菌致死所产生的玉米螟僵虫数及僵虫率逐年上升,玉米螟天敌数量也逐年增加。调查结果表明:白僵菌可以在自然环境中对玉米螟有持续的防治效果,且施用白僵菌封垛地区的防治效果高于未施用地区,防治效果提升4.2倍。
        In order to find out whether Beauveria bassiana had the continuous control effect on Asiatic corn `borer in the natural conditions, the dead larvae caused by infection of B. bassiana were investigated in the towns of used and unused region of B. bassinan in western of Jilin Province. The results of investigation showed that control effect of B.bassinan parasitism were dominant in the area of investigation. The number and rate of white muscardine caused by B. bassiana had increased every year, and the number of natural enemies had been increasing each year. The results showed that B. bassiana had the continuous control effect on Asiatic corn borer in natural conditions, and the used region was better than the unused, the effect promoted by 4.2 times.
