Wolbachia pipientis Hertig和沃尔巴赫（立克次体目：立克次体科）是白纹伊蚊（Skuse）（双翅目：蚊科）和许多其他无脊椎动物中天然存在的细胞内α-变形菌。这些内共生体可以通过操纵宿主繁殖来入侵宿主种群。沃尔巴克氏体感染已被证明在发育、存活和繁殖方面对宿主既有成本又有收益。在这里，我们监测种内竞争感染或未感染的幼虫之间的独立队列。竞争水平的操纵不同的初始幼虫密度和食物水平。虽然幼虫密度观察到有重大影响不成熟的存活率，羽化成人的性别比，和发育率，沃尔巴克氏体感染状况有最小的影响，男性不成熟的女性在这些实验条件下，没有影响。雌性和雄性未成熟体对竞争压力的反应不同，雌性和雄性的功能关系分别与争夺和竞争竞争相一致。结果进行了讨论，在自然发生的沃尔巴克氏体感染的演变。白纹伊蚊（即，自然人口更替事件）和公共卫生战略，提出了操纵沃尔巴克氏体感染的Ae。白纹伊蚊种群
Wolbachia pipientis Hertig and Wolbach (Rickettsiales: Rickettsiaceae) are intracellular α-proteobacteria that occur naturally in Aedes albopictus (Skuse) (Diptera: Culicidae) and numerous other invertebrates. These endosymbionts can invade host populations by manipulating host reproduction. Wolbachia infections have been shown to impart both costs and benefits to hosts in terms of development, survival, and fecundity. Here, we monitor intraspecific competition among independent cohorts of infected or uninfected larvae. Levels of competition are manipulated by varying initial larval densities and food levels. Although larval density is observed to have major impacts on immature survivorship, sex ratio of eclosing adults, and developmental rates, the Wolbachia infection status had minimal impact on male immatures and no effect on immature females under these experimental conditions. Female and male immatures were observed to respond differently to competitive pressure, with the functional relationships of females and males consistent with scramble and contest competition, respectively. The results are discussed in relation to the evolution of naturally occurring Wolbachia infections in Ae. albopictus (i.e., natural population replacement events) and public health strategies that propose the manipulation of Wolbachia infections in Ae. albopictus populations.
