Facultative bacterial endosymbionts are common, influential associates of arthropods, yet their movement among host species has not been well documented. Plant-mediated transmission of Rickettsia has been shown for the whitefly Bemisia tabaci. Bemisia tabaci in USA cotton fields harbors the secondary symbionts Rickettsia and Hamiltonella, and co-occurs with Trialeurodes sp. nr. abutiloneus whiteflies. To determine whether symbionts may be shared, the microbial diversity of these whiteflies on cotton across the USA was analyzed. Trialeurodes sp. nr. abutiloneus bore Portiera, Pseudomonas, Serratia, Arsenophonus and Wolbachia. No Rickettsia or Hamiltonella were detected. These results provide no evidence for horizontal transmission of symbionts between these whitefly genera.
兼性细菌内共生体是节肢动物常见且有影响力的共生伙伴，然而它们在宿主物种间的转移尚未得到充分记录。烟粉虱的立克次氏体可通过植物介导传播。美国棉田中的烟粉虱携带次生共生体立克次氏体和汉密尔顿菌，并与近棉粉虱属粉虱同时出现。为确定共生体是否会共享，分析了美国各地棉花上这些粉虱的微生物多样性。近棉粉虱携带了布氏菌、假单胞菌、沙雷氏菌、嗜菌属和沃尔巴克氏体。未检测到立克次氏体或汉密尔顿菌。这些结果没有为这些粉虱属之间共生体的水平传播提供证据。
