辽宁地区温室内粉虱的种类及分布

摘要

In order to reveal the distribution of the whiteflies, a systematic and comprehensive survey on its species composition was conducted in Liaoning province. Thirty-three collections of adult whiteflies were sampled from 21 locations in 12 cities of Liaoning from the end of 2014 to early 2015. Mitochondrial cytochrome oxidase I (mtDNA COI)gene sequences were used to identify the species of whiteflies. The result showed that there were Trialeurodes vaporariorum (Westwood), MEAM1 and MED Bemisia tabaci (Gennadius) in Liaoning. The percentage of B.tabaci was 100% in Dashiqiao, Zhangwu, Kazuo, Jianping, Jinxing, Suizhong, Donggang, with the majority of MED. The percentage of T.vaporariorum was 100% in Mingshan, Faku, Xinmin, Zhenan, Tieling. Wafangdian, Pulandian, Lingyuan, Linghai, Liaozhong, Shenhe, Dawa, Haicheng and Fengcheng had mixure species. The Trialeurodes vaporariorum only in Shenhe and Dawa were biotic population.%为了探明目前辽宁地区温室大棚内粉虱的种类与分布情况，于2014年底到2015年初对辽宁省不同地区采集的粉虱成虫进行了系统调查。从辽宁省12市21个不同地区采集了粉虱成虫样品，利用mtDNA COI 对粉虱的种类进行了鉴定。结果表明，在辽宁省温室内，温室白粉虱[Trialeurodes vaporariorum(Westwood)]与烟粉虱[Bemisia tabaci(Gennadius)]的MEAM1隐种和MED隐种都有分布，其中在营口市的大石桥、阜新市的彰武、朝阳市的喀左和建平、葫芦岛市的金星和绥中、丹东市的东港均为烟粉虱，且MED隐种烟粉虱占优势，本溪市的明山、沈阳市的新民和法库、丹东市的振安、铁岭市的铁岭县为温室白粉虱，大连的瓦房店和普湾、朝阳的凌源、锦州的凌海、沈阳的辽中和沈河、盘锦的大洼、鞍山的海城、丹东的凤城为混合发生，温室白粉虱仅在沈阳市沈河区和盘锦市大洼县为优势种群。
