Abstract：Toexplore thechemical controltechnologyagainst Scirtothrips dorsalisin simulative ancienttea gardens， three low-toxicitypesticides，namely 35% diafenthiuron. dinotefuran suspension concentrate， 30% flonicamid.bifenthrin suspension concentrate and 11.8% emamectin benzoate. tolfenpyrad suspension concentrate，were selected to conduct fieldefficacy trials.Thecontrol effcts of diferent low-toxicitypesticides and their impacts on tea production were investigated.Theresults show that，14 days afterapplication，the populationreductionrateand relativecontrol effect of 35% diafenthiuron.dinotefuran suspension concentrate at dilution ratios of 1：1 100 to 1：1 750 and of 11.8% （204号 emamectin benzoate. tolfenpyrad suspension concentrate at dilution ratios of 1：980 to 1：1200 against S. dorsalis reached over 90% and 80% ，respectively， with no significant difference between the pesticide treatments.Therefore， spraying 35% diafenthiuron. dinotefuran suspension concentrate at a dilution ratio of 1：1750 and a solution of 11.8% （20 emamectin benzoate. tolfenpyrad suspension concentrate at a dilution ratio of 1：1200 is recommended as a green preventive measure against S. dorsalis in simulative ancient tea gardens.
