烟粉虱Bemisia tabaci（Gennadius）（半翅目：粉虱科）体内含有多种细菌共生体。在次级（兼性）共生体中，汉米尔顿氏菌具有高流行率和高感染频率，这表明它可能对其宿主的生物学和生态学具有重要意义。以前的报告表明，汉米尔顿增加粉虱健身，并根据其基因组的完整测序，可能有能力合成辅因子和氨基酸所需的主机，但没有充分合成的主机或由主要内共生体，Portiera。在这里，我们评估了汉密尔顿感染对B生长的影响。烟粉虱饲养低，标准，或高氮饮食。当B.烟粉虱饲养在一个标准的氮饮食，没有成本或效益与汉米尔顿感染。但是，如果我们以低氮饮食饲养粉虱，感染汉米尔顿杆菌的粉虱通常比未感染的粉虱生长得更好。此外，在现场收集粉虱的氮水平表明，在该领域的营养条件是可比的低氮饮食在我们的实验室实验。这些数据表明，汉密尔顿可能发挥以前未被认识到的作用，作为一个营养互惠在B。烟粉虱
The whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) harbors several bacterial symbionts. Among the secondary (facultative) symbionts, Hamiltonella has high prevalence and high infection frequencies, suggesting that it may be important for the biology and ecology of its hosts. Previous reports indicated that Hamiltonella increases whitefly fitness and, based on the complete sequencing of its genome, may have the ability to synthesize cofactors and amino acids that are required by its host but that are not sufficiently synthesized by the host or by the primary endosymbiont, Portiera. Here, we assessed the effects of Hamiltonella infection on the growth of B. tabaci reared on low-, standard-, or high-nitrogen diets. When B. tabaci was reared on a standard-nitrogen diet, no cost or benefit was associated with Hamiltonella infection. But, if we reared whiteflies on low-nitrogen diets, Hamiltonella-infected whiteflies often grew better than uninfected whiteflies. Furthermore, nitrogen levels in field-collected whiteflies indicated that the nutritional conditions in the field were comparable to the low-nitrogen diet in our laboratory experiment. These data suggest that Hamiltonella may play a previously unrecognized role as a nutritional mutualist in B. tabaci.
