Abstract

Thrips tabaci Lindeman is one of the most important polyphagous horticulture crop pests in Lithuania. The aim of this work was to investigate new approach with the geographic distributions and host plant associations between different mtDNA COI haplotypes of T. tabaci. Specimens of T. tabaci were collected from different horticultural crops in the main horticulture regions across Lithuania, where sustainable plant protection practice is used. Four different haplotypes of T. tabaci were detected during investigation, and the greatest haplotype diversity was registered in the northern districts of Lithuania. The mean genetic distance between different haplotypes was 1.6%, and diversity was up to 2.9% comparing with sequences from other European countries (the Netherlands, UK and France) deposited in GenBank. Sequences obtained during this investigation differed by ≥10% comparing with sequences from other countries. Thrips tabaci COI gene differences partly reflect the geographic distribution, but results did not reveal the relationship between COI gene polymorphism of T. tabaci and different host plants.

立陶宛洋葱蓟马(thrips tabaci Lindeman，蓟马科)种群的遗传变异及其与寄主植物的联系

毒蜥是立陶宛最重要的多食性园艺作物害虫之一。本工作的目的是研究烟草不同mtDNACOI单倍型之间的地理分布和寄主植物相关性的新方法。烟草标本是从立陶宛主要园艺区的不同园艺作物中采集的，这些地区采用了可持续的植物保护做法。在调查过程中检测到四种不同的烟草单倍型，立陶宛北部地区的单倍型多样性最大。与GenBank中保存的其他欧洲国家（荷兰、英国和法国）的序列相比，不同单倍型之间的平均遗传距离为1.6%，多样性高达2.9%。本次调查中获得的序列与其他国家的序列相比差异≥10%。Thrips tabaci COI基因的差异在一定程度上反映了地理分布，但结果并没有揭示烟草COI基因多态性与不同寄主植物的关系。
