The white-backed planthopper, Sogatella furcifera (Horváth) (Hemiptera: Delphacidae), is a major pest of rice and has long-range migratory behavior in Asia. Microsatellite markers (simple sequence repeats) have been widely used to determine the origins and genetic diversity of insect pests. We identified novel microsatellite loci for S. furcifera samples collected from Laos, Vietnam, and three localities in Bangladesh from next-generation Roche 454 pyrosequencing data. Size polymorphism at 12 microsatellite loci was verified for 40 adult individuals collected from Shinan, South Korea. The average number of alleles per locus was 7.92. The mean values of observed (H(o)) and expected heterozygosities (H(E)) were 0.615 and 0.757, respectively. These new microsatellite markers will be a resource for future ecological genetic studies of S. furcifera samples across more broad geographic regions in Asia and may assist in estimations of genetic differentiation and gene flow among populations for implementation of more effective management strategies to control this serious rice pest.
白背飞虱,即褐飞虱(Horváth)(半翅目:飞虱科),是水稻的主要害虫,在亚洲具有远距离迁飞行为。微卫星标记(简单序列重复)已被广泛用于确定害虫的起源和遗传多样性。我们从下一代罗氏454焦磷酸测序数据中为从老挝、越南和孟加拉国三个地区采集的褐飞虱样本鉴定了新的微卫星位点。对从韩国始安采集的40只成年个体验证了12个微卫星位点的大小多态性。每个位点的平均等位基因数为7.92。观察到的杂合度(H(o))和预期杂合度(H(E))的平均值分别为0.615和0.757。这些新的微卫星标记将为未来在亚洲更广泛地理区域对褐飞虱样本进行生态遗传学研究提供资源,并可能有助于估计种群间的遗传分化和基因流动,以实施更有效的管理策略来控制这种严重的水稻害虫。
