用点滴法和药膜法测定了多种类型杀虫剂对桔小实蝇Bactrocera dorsalis(Hendel)敏感品系成虫的触杀作用毒力,确定了敏感基线。点滴法测定结果表明,14种杀虫剂对桔小实蝇成虫的毒力从大到小顺序是甲维盐、阿维菌素、敌敌畏、高效氯氰菊酯、辛硫磷、功夫、氯氰菊酯、灭多威、敌百虫、吡虫啉、硫丹、啶虫脒、甲氰菊酯、杀螟丹,24h致死中量分别为1.20ng/头、5.48ng/头、11.33ng/头、11.58ng/头、14.04ng/头、14.04ng/头、19.81ng/头、63.52ng/头、94.84ng/头、496.62ng/头、616.55ng/头、808.43ng/头、942.53ng/头、10841.97ng/头。药膜法测定结果表明,8种杀虫剂对桔小实蝇成虫的毒力由大到小依次为甲维盐、高效氯氰菊酯、功夫、辛硫磷、氯氰菊酯、敌百虫、灭多威、阿维菌素,24h致死中浓度分别为0.88mg/L、1.86mg/L、1.94mg/L、2.05mg/L、4.86mg/L、4.93mg/L、7.38mg/L、12.43mg/L。
The contact toxicity of various types of insecticides to adult adults of the Bactrocera dorsalis (Hendel) susceptible strain was determined by spotting and membrane assay, and the sensitive baseline was determined. The results of drip method showed that the order of the virulence of 14 insecticides to adults of Bombyx mori was avermectin, abamectin, dichlorvos, cypermethrin, phoxim, kung fu, cypermethrin, The median lethal doses of the two agents were 1.20ng / head, 5.48ng / head, 11.33ng / head and 11.58ng / head respectively, 14.04 ng / head, 19.81 ng / head, 63.52 ng / head, 94.84 ng / head, 496.62 ng / head, 616.55 ng / head, 808.43 ng / head, 942.53 ng / head, 10841.97 ng / head. The results of the membrane assay showed that the virulences of the eight insecticides to adults of the fruit fly were as follows: carbaryl, beta-cypermethrin, kung fu, phoxim, cypermethrin, trichlorfon, methomyl, The concentrations of abamectin in 24 h were 0.88 mg / L, 1.86 mg / L, 1.94 mg / L, 2.05 mg / L, 4.86 mg / L, 4.93 mg / L, 7.38 mg / L and 12.43 mg / L respectively .
