摘　　要：稻小潜叶蝇在辽宁省各地稻田均见发生。田块低洼,周围为荒地、沼泽,禾本科杂草丰度较大的稻田发生较重;弯穗型品种较直立穗品种受害重。稻小潜叶蝇年发生4~5代,以第2代于水稻返青分蘖期发生为害水稻为主。登记药剂匮乏,以潜叶蝇、斑潜蝇登记药和防治返青分蘖期其他害虫的稻田常用药剂进行田间药效试验,采用育秧播种前拌种、移栽前苗床施药带药移栽和本田返青期全田施药3种处理方式施药,其中,苗床施药带药移栽方式最为经济有效。考虑到兼治其他害虫,农药品种以呋虫胺和氯虫苯甲酰胺为最优,防治效果为87.12%~91.76%,对稻水象甲等害虫的兼治效果较好。Hydrellia sinica was found in rice fields in Liaoning Province.The field is low,surrounded by wasteland or swamp,and the rice field with higher grass weed abundance is heavier.The bent panicle varieties suffered more than the upright panicle varieties.Rice leaf miner occurs in 4 to 5 generations,and the second generation mainly occurs at the tillering stage of rice.Due to the shortage of registered agents,the field efficacy test was carried out with registered agents of leaf miner and Maculata fly and other common agents used to control other pests at tillering stage.Three treatment methods were applied:seed dressing before seeding,bed with medicine transplanting before transplanting,and the whole field with medicine at replanting stage.Among them,bed with medicine transplanting was the most economical and effective.Considering other pests,the best pesticide varieties were dinotefuran and chlorobenzamide,the control effect was 87.12%~91.76%,and the control effect was better on rice water weevil and other pests.
