摘　　要：目的调查苏云金芽孢杆菌以色列亚种(Bti)水剂对新疆额尔齐斯河下游河岸谷盆地区蚋的控制效果。方法 2012-2015年在新疆生产建设兵团第十师185团,通过室内和野外试验测试Bti对蚋的杀灭能力;采用SPSS 19.0软件的Probit回归方法计算半数致死浓度(LC_(50))、90%致死浓度(LC_(90))及其95%CI。结果在实验室条件下,Bti对蚋幼虫的LC_(50)和LC_(90)分别为0.034×10^(-6)和0.118×10^(-6)g/ml;野外大面积施用Bti,12 h对蚋幼虫的杀灭率>83.21%,24 h杀灭率>97.07%;2013-2015年该地区连续施用Bti,蚋成虫数量降低了89.43%。结论 Bti水剂对蚋幼虫有良好的杀灭和防控效果,对新疆额尔齐斯河下游地区蚋成虫的防控效果显著,为野外蚋的生物防治提供了参考依据。Objective Application of aqueous suspension of Bacillus thuringiensis subsp. israelensis（Bti） on the control of blackfly in the lower reaches of Irtysh River in Xinjiang Uygur Autonomous Region. Methods The pesticidal activity of Bti on blackfly larvae was tested through bioassay and field experiments, respectively. The LC50 and LC90 were computed by the Probit regression analysis method in the SPSS 19.0 software. Results The Bti aqueous suspension is an effective pesticide for blackfly control. The bioassay result suggested the LC50 was 0.034×10^-6g/ml and the LC90 was 0.118×10^-6g/ml.In field tests, the control efficacy of blackfly larvae was more than 83.21% in 12 h and more than 97.07% in 24 h. From2013 to 2015, the adult population density of blackfly in the continuous application area decreased by 89.43%.Conclusion Bti aqueous suspension is an effective pesticide to control blackfly larvae, which is efficient for the prevention and control of adult blackfly in the lower reaches of the Irtysh River in Xinjiang Uygur Autonomous Region.
