Abstract：InvieofthecurrenthiglevelresistanceofChilosuppresslisoditionalisecticdesanditsariniceprouction thisstudyselected9indsofommonlyusedisectiidesfortecontrolofChilosuppresslisndsreeedouteficintwieticidestoreplacetraditioalisecticidstoughfeldfcacytstsstoompreesivelymproeontrollvelofils salis.The results showed that 10 % cyclopropyl fipronil and 2 % chlorantraniliprole + 3 2 % monosultap showed higher control effect and longer efficacy duration in the control of Chilo suppressalis，with the highest control effect of 9 4 . 7 % and 9 3 . 1 % ，and the comprehensive control effect was the best. The control effects of 10 % chlorantraniliprole and 9 % chlorantraniliprole+2.6% Emamectin salt SC respectivelyreached 8 7 . 8 % and 8 5 . 7 % .However，there were significant diferences in the performance under different application time，whichmayberelatedtothechemicalcomposition，mechanismofctionandenvironmentalfactors，andneedtobefurthrerified.The comprehensive control effect of other pesticides was poor，and the lowest was only 4 . 9 % . In conclusion，the control effect of （204号 10 % cyfluthrin and 2 % chlorantraniliprole + 3 2 % monosultap is outstanding，and the eficacy duration is long，so the author suggests giving priority to the use in actual production.
