烟粉虱和温室粉虱均是世界性害虫。两种粉虱形态相似,体被白色蜡粉,极难区分,有许多共同的寄主,常混合发生。常规防治粉虱多采用化学农药,而粉虱种群繁殖速度快,世代重叠现象明显,化学农药的长期、过量使用,导致粉虱已对多种杀虫剂产生了不同程度的抗性。北京地区的温室粉虱对阿维菌素的抗药性是最低的,抗性倍数
Bemisia tabaci and greenhouse whitefly are worldwide pests. Two whitefly morphological similarities, the body was white wax, extremely difficult to distinguish, there are many common host, often mixed occurrence. Conventional prevention and control of whitefly use more chemical pesticides, and whitefly populations reproduce fast, obvious overlapping generations, chemical pesticides long-term, excessive use, resulting in whiteflies have a variety of insecticides have varying degrees of resistance. Beijing greenhouse whitefly resistance to avermectin resistance is the lowest, multiple of resistance
