为了明确北京地区蔬菜烟粉虱的种群发展动态及对常用烟碱类杀虫剂的抗药性,为烟粉虱防治适期的确定及高效杀虫剂的选择提供基础资料及科学指导,东北农业大学生命科学学院和中国农业科学院蔬菜花卉研究所研究人员于2009年调查了北京地区春茬和秋茬蔬菜烟粉虱的种群动态,并监测了该地区2009～2011年度烟粉虱种群对3种烟碱类杀虫剂的抗药性。 In order to clarify the population dynamics of Bemisia tabaci (Bemisia tabaci) and its resistance to common nicotine insecticides in Beijing, provide the basic information and scientific guidance for determining the suitable control period of Bemisia tabaci and selecting the effective insecticides, Researchers at the College of Life Sciences and the Institute of Vegetables and Flowers, Chinese Academy of Agricultural Sciences in 2009 investigated the population dynamics of Bemisia tabaci in spring and autumn in Beijing and monitored the effects of Bemisia tabaci in three populations Insecticide resistance of nicotine insecticides.
