| 摘 要： | 近年来烟粉虱Bemisia tabaci(Gennadius)Q型入侵我国并在部分地区取代B型成为了烟粉虱优势生物型。外来物种的入侵过程及农药使用等因素可影响种群的遗传多样性水平及其遗传结构。本研究分析了4个微卫星位点在Q型烟粉虱入侵种群的多态信息含量(PIC),并在此基础上进行了遗传多样性分析。结果表明这些微卫星位点在Q型烟粉虱入侵种群中具有中度或高度多态性,说明微卫星位点能有效分析Q型入侵种群的遗传多态性。本研究为利用微卫星标记研究Q型入侵种群的遗传结构奠定了基础。

| Abstract: | During the past several years,the Bemisia tabaci(Gennadius) Q-biotype has invaded China and become the predominant biotype by replacing the previously established B-biotype in some areas.B.tabaci's genetic polymorphism could be influenced by the invasion process and pesticides used.The polymorphism information content(PIC) of 4 microsatellite loci in Q-biotype populations from Shandong Province was assessed and used to determine the genetic diversity of these populations.The results show that all 4 loci wer... |
