摘　　要：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％。Field application technique of Beauveria brongniartii for white grub control has been studied. The best time and dose of application of B. brongniartii has been determined. At the mid term ploughing time, using 150×10 12 spo re/ha or 75×10 12 spore/ha+1.2kg 40% isofenphos methyl we can get 80% c ontrol effect. In 1992～1994, in Shandong province and Jiangsu province, 300ha has been applied and the control result was about 70%￣80%. The result demonstr ated that B. brongniartii is a profitable bio control agent against white g rub in groundnut field.
