Wolbachia is an obligate intracellular bacterium with a high frequency of infection and a continental distribution in arthropods and nematodes. This endosymbiont can induce various reproductive phenotypes in their hosts and has been previously found naturally in several pests including thrips (Thripidae). These insects cause physical fruit damage and economic losses in avocado. The presence of Wolbachia was evaluated for the first time in avocado thrips populations of Frankliniella sp. and Scirtothrips hansoni sp.n. from eastern Antioquia. DNA from adult thrips individuals was used to assess the detection of Wolbachia by amplifying a fragment (600 bp) of the Wolbachia major surface protein (wsp) gene. Results confirmed the presence of two new Wolbachia strains in these two thrips species, with a higher percentage of natural infection in S. hansoni sp.n. The first Wolbachia species was found in Frankliniella sp. and belongs to supergroup A and the second was detected in S. hansoni sp.n. and is part of supergroup B. Wolbachia was more frequently found in females (32.73%), and only found in one male. Analysis of phylogenetic relationships, suggests that the two new Wolbachia sequences (wFran: Frankliniella and wShan: Scirtothrips hansoni) detected here represent two new groups for this endosymbiont. The haplotype network shows the presence of two possible haplotypes for each strain. Future studies to evaluate the possible use of Wolbachia as a control agent in avocado thrips are necessary.

沃尔巴克氏体是一种专性细胞内细菌，感染频率高，大陆分布于节肢动物和线虫中。这种内共生体可以在宿主体内诱导各种生殖表型，并且之前已在包括蓟马（蓟马科）在内的多种害虫中自然发现。这些昆虫会对鳄梨造成果实物理损害和经济损失。首次在牛油果蓟马Frankliniella sp. 种群中评估了沃尔巴克氏体的存在。和硬蓟马 hansoni sp.n。来自安蒂奥基亚东部。成年蓟马个体的 DNA 用于通过扩增沃尔巴克氏体主要表面蛋白 ( wsp )基因的片段 (600 bp)来评估沃尔巴克氏体的检测。结果证实这两种蓟马中存在两种新的沃尔巴克氏体菌株，其中汉氏链球菌自然感染的比例较高。第一个沃尔巴克氏体物种是在Frankliniella sp. 中发现的。属于 A 超群，第二个是在S. hansoni sp.n中检测到的。属于B超群的一部分。沃尔巴克氏体在女性中更常见（32.73%），仅在一名男性中发现。系统发育关系分析表明，此处检测到的两个新的沃尔巴克氏体序列（wFran：Frankliniella和wShan：Scirtothrips hansoni）代表了该内共生体的两个新类群。单倍型网络显示每个菌株存在两种可能的单倍型。未来有必要进行研究来评估沃尔巴克氏体作为牛油果蓟马防治剂的可能性。
