摘　　要： 测定了绿僵菌、毒死蜱、辛硫磷等药剂对草坪害虫的控制效果。结果表明绿僵菌、毒死蜱和辛硫磷都是防治草坪地下害虫的有效药剂，毒死蜱和辛硫磷还能有效防治草坪茎叶害虫禾灰翅夜蛾和斜纹夜蛾等。药后45d，绿僵菌对铜绿丽金龟幼虫蛴螬的防效和对地下害虫的总防效分别为91．2％和87．6％。绿僵菌对茎叶害虫的防效较差，药后3、7、10d时，对禾灰翅夜蛾的防效分别为3．7％、9．2％和18．9％；对茎叶害虫的总防效在12．2％以下。辛硫磷和毒死蜱药后3d对禾灰翅夜蛾的防效分别是93．7％和97．6％；对茎叶害虫的总防效分别是92．0％和93．6％。当高效氯氰菊酯分别和辛硫磷、毒死蜱混用防治斜纹夜蛾时，防效更高、速效性更好。 The efficacy of Metarhizium anisopliae, chlorpyrifos, phoxim, and other pesticides in controlling turf insect pests was determined. M. anisopliae, chlorpyrifos, and phoxim provided good control of subterranean turf insect pests, and chlorpyrifos and phoxim also controlled the foliar turf insect pests Spodoptera mauritia, Prodenia litura, and others. Forty-five d after application, M. anisopliae provided 91.2 and 87.6% control of immature grubs （Anomala corpulenta） and total subterranean insect pests, respectively. M. anisopliae did not effectively control foliar insects, with 3.7, 9.2, and 18.9% control ofS. mauritia provided at 3, 7, and 10 d after application, respectively, and 〈12.2% control of total foliar insect pests. Chlorpyrifos and phoxim provided 93.7 and 97.6% control, respectively, of S. mauritia, and 92.0 and 93.6% control, respectively, of total foliar insects 3 d after application.
