Wolbachia are endosymbiotic bacteria that cause reproductive alterations in numerous arthropod species. Using a PCR-based method, we found that, out of 33 odonate species, four species were infected with Wolbachia. This finding represents the first record of Wolbachia infection in tropical odonates. Identical wsp gene sequences were found in the Wolbachia-infected common odonate species, Agriocnemis f. femina, collected from different locations in Thailand. The infection frequencies in several natural populations suggest that replacement of uninfected populations by Wolbachia-infected ones has recently occurred in this damselfly species.
沃尔巴克氏体是一种内共生细菌，可导致众多节肢动物物种发生生殖改变。通过基于聚合酶链式反应（PCR）的方法，我们发现，在33种蜻蜓目物种中，有4种感染了沃尔巴克氏体。这一发现代表了热带蜻蜓目昆虫感染沃尔巴克氏体的首次记录。在从泰国不同地点采集的感染沃尔巴克氏体的常见蜻蜓目物种——雌性黄纹细蟌中，发现了相同的表面蛋白（wsp）基因序列。几个自然种群中的感染频率表明，最近在这种豆娘物种中发生了未感染种群被感染沃尔巴克氏体的种群所取代的情况。
