摘　　要：采用浸叶法开展了7种杀虫剂对温室棕榈蓟马成虫的室内毒力测定,并对效果较好的2种药剂进行田间药效试验.室内生物测定结果表明,多杀菌素、甲氨基阿维菌素苯甲酸盐对棕榈蓟马成虫的LC50分别为0.079mg/L和0.443mg/L,而阿维菌素、灭多威、啶虫脒、高效氯氟氰菊酯LC50值为47.908～206.236mg/L.田间药效试验结果表明,2.5％多杀菌素悬浮剂和2.2％甲氨基阿维菌素苯甲酸盐微乳剂使用剂量以80～60 g/667m2和30～20 g/667m2防治效果较理想.Indoor toxicity of seven kinds of insecticides against Thrips palmi adults collected from solar greenhouse were evaluated by leaf-dipping method and field trials were carried out with two effective insecticides.The results of bioassay showed that the LC50 of spinosad and emamectin-benzoate against T.palmi adults were 0.079 mg/L and 0.443 mg/L,respectively,while the LC50 of abamectin,methomyl,acetamiprid and lambda-cyhalothrin ranged from 47.908 mg/L to 206.236 mg/L.Field trials demonstrated that 2.5％ spinosad SC and 2.2％ emamectin-benzoate ME provided good control efficacy at the doses of 80-60 g/667 m2 and 30-20 g/667 m2,respectively.
