摘要
烟粉虱[Bemisia tabaci(Gennadius)]为辽宁省重要温室害虫,包括MEAM1隐种与MED隐种。为了揭示近年来辽宁省冬季温室内烟粉虱隐种动态,采用线粒体细胞色素氧化酶I(mtCOI)PCR-RFLP技术,鉴别了辽宁省9个地区13个烟粉虱种群的隐种。结果表明,2019年冬季辽宁各地温室烟粉虱种群有12个种群均为MED隐种烟粉虱,为优势隐种,只有沈阳1个种群存在MEAM1隐种,发现在温室豆角(SY2)上采集的26头烟粉虱中,检出1头MEAM1隐种烟粉虱,比率为3.85%。
The whitefly Bemisia tabaci(Gennadius)is an important insect pest in the winter greenhouse in Liaoning of China,including MED and MEAM1 cryptic species.To clarify the population and the distribution of B.tabaci cryptic species in the winter greenhouse in Liaoning,we identified 13 B.tabaci populations from nine counties by analyzing the sequence of the mitochondrial cytochrome oxidase I(mtCOI)gene with the PCR-RFLP method.The results showed that there was only one population was composed of both B.tabaci MEAM1(made up 3.85%of the population)and B.tabaci MED while the other 12 populations were composed of B.tabaci MED only.It can be inferred that the B.tabaci MED has been the dominant species in the winter greenhouse in Liaoning.
