卵孢白僵菌防治苗圃地蛴螬的研究结果表明，卵孢白僵菌ＡＢ菌株，每公倾施菌量１１２５～１５０ｋｇ，对东北大黑鳃金龟子有较强的寄生力，苗圃地防治效果达６６９％～８５％，僵虫率为５５６％～６８４％，虫口减退率达到６９１％～９３３％，防治效果明显。该菌株对淡翅黎丽金龟子寄生力较差，防治效果５６２％；白僵菌与化学农药３９１１分层施用，防治效果达９８７％，虫口减退率较单施３９１１防治区降低了２６２％。白僵菌与芫菁夜蛾线虫交错施用，防治效果可达到８９％以上，比单施白僵菌防治效果提高３３４％以上。土壤中施白僵菌，不仅当年对蛴螬有控制作用，而且第二年仍有作用。 The results showed that Beauveria bassiana strain AB had a strong parasitism on the black-beaked Scarab in Northeast China and the prevention and control of nursery The effect was 66.9% ~ 85%, the rate of the sturgeon was 55.6% ~ 68.4%, and the drop rate of the population was 69.1% ~ 93.3%. The control effect was obvious. The strain had less parasitism on Pealia leiiensis and the control effect was 562%. Beauveria bassiana and chemical pesticide 3911 were applied layer by layer, and the control effect was 987%. The rate of population decline was lower than that of 3911 26  2%. Beauveria bassiana and moth caterpers nematode staggered application, the control effect can reach more than 89%, than the single Beauveria control effect increased by 33  4%. Beauveria bassiana was applied to the soil, which not only controlled the catfish in the same year, but also played a role in the following year.
