沃尔巴克氏体是一种细胞内细菌，在许多节肢动物宿主中诱导表型效应，以增强其自身在宿主种群内的传播。沃尔巴克氏体通常感染南美土著人群中的红色入侵火蚁（Solenopsis invicta）。先前的一项研究未能在美国引进的火蚁中检测到沃尔巴克氏体。我们进行了广泛的研究，从1157巢收集的个人在美国10个广泛的地理种群。在密西西比南部两个邻近种群的蚂蚁中检测到沃尔巴克氏体，不同的变体（wsp基因序列）感染了多皇后（polygyne）与单皇后（monogyne）社会形式的蚂蚁。对引进的S.最近有一种或多种受沃尔巴克氏体感染的火蚁被引入美国南部。
Wolbachia are intracellular bacteria that induce phenotypic effects in many arthropod hosts to enhance their own transmission within host populations. Wolbachia commonly infect the Red Imported Fire Ant, Solenopsis invicta, in native South American populations. A previous study failed to detect Wolbachia in fire ants from the introduced range in the USA. We conducted an extensive study of individuals collected from 1157 nests from 10 widespread geographical populations in the USA. Wolbachia were detected in ants from two nearby populations in southern Mississippi, with different variants (wsp gene sequences) infecting ants from colonies of the multiple-queen (polygyne) vs. single-queen (monogyne) social forms. The parsimonious explanation for the presence of Wolbachia in introduced S. invicta is that there have been one or more recent introductions of Wolbachia-infected fire ants into the southern USA.
