摘要： 报道了韭菜迟眼蕈蚊的人工饲养方法,测定了灭蝇胺、灭线磷、地亚农、辛硫磷、毒死蜱、丁硫克百威和硫丹对韭菜迟眼蕈蚊幼虫和成虫的毒力及药效。结果表明,药后48h时以毒死蜱和硫丹对韭菜迟眼蕈蚊幼虫的毒力最高,药后72h灭线磷和丁硫克百威的毒力迅速上升,对韭菜迟眼蕈蚊的毒力与硫丹、毒死蜱接近,LC50约为50～100μg/mL。药后4h毒死蜱和丁硫克百威对韭菜迟眼蕈蚊雌成虫的毒力较高,10h时以毒死蜱和灭线磷的毒力较高。田间药效证明,毒死蜱和灭线磷速效性好,药后5d7500L/hm2防效达到75%以上。药后15d灭蝇胺的田间防效迅速提高,致使部分幼虫和蛹在形态上发生畸变,减少成虫产卵量。

Abstract: Technique of artificial feeding Bradysia odoriphaga was reported.Laboratory and field trials were conducted to control Bradysia odoriphaga with cyromaine,ethoprphos,diazinon,phoxim,chlorpyrifos,carbosulfan and endosulfan.Results showed the toxicities of chlorpyrifos and endosulfan to larva were higher than others after 48 h,toxicity of ethoprphos and carbosulfan increase quickly and approach to toxicity of endosulfan and chlorpyrifos,attained 50～100 μg/mL after 72h.Toxicities of chlorpyrifos and carbosulfan to female adults were higher than other insecticides after 4h,toxicities of chlorpyrifos and ethoprphos were the two higher insecticides after 10h.In field,Chlorpyrifos and ethoprphos had quick control effects,could obtain 75% effects in the dose of 7 500 mL/ha after 5 d.Toxicity of cyromaine was increased quickly after 15 d.Treating larva with cyromaine could lead to the larva and pupa abnormal and lead to the next generation adults egging little.
