经蛴螬的田间防治试验，确定了防治的最佳时期和最佳剂量，在花生中耕期每公顷用卵孢白僵菌１５０万亿孢子或７５万亿孢子＋１．２ｋｇ４０％甲基异柳磷乳油防治大黑、暗黑金龟子，可获得８０％的防治效果。１９９２～１９９４年在江苏、山东和河北３００ｈｍ２防治示范，效果可达６０％～８０％，表明卵孢白僵菌是有潜力的蛴螬生物杀虫剂 After a series of experiments in the field, the optimal period of prevention and treatment and the optimal dosage were determined. In the peanut cultivating period, 150 trillion spores of Beauveria bassiana or 75 trillion spores + 1.2 kg of 40% Prevention and treatment of large black, dark chafer, get 80% control effect. 1992 to 1994 in Jiangsu, Shandong and Hebei 300hm2 prevention and control demonstration, the effect of up to 60% to 80%, indicating that Beauveria bassiana is a potential biotic insecticide
