Wolbachia-induced cytoplasmic incompatibility in single- and superinfected Aedes albopictus (Diptera: Culicidae).
Maternally inherited bacteria of the genus Volbachia can cause cytoplasmic incompatibility resulting in the developmental arrest of early embryos. Previous studies have shown that both single- and superinfections of Wolbachia naturally occur in populations of Aedes albopictus (Skuse). Here, we report crossing experiments using three infection types occurring in Ae. albopictus: uninfected, singl...
متن کاملRrh: Wolbachia Superinfection in Aedes Albopictus Title: Origin of Wolbachia Superinfection in Aedes Albopictus by Sequential Population Replacement
A reproductive advantage afforded to female hosts by obligate intracellular Wolbachia infections can result in the spread of the vertically-inherited bacteria into the host population, replacing the uninfected cytotype (population replacement). Here we examine Wolbachia infection dynamics relevant to the origin of Wolbachia superinfection (i.e., host individuals that are co-infected with two or...
متن کاملWolbachia Age-Sex-Specific Density in Aedes albopictus: A Host Evolutionary Response to Cytoplasmic Incompatibility?
BACKGROUND Wolbachia bacteria have invaded many arthropod species by inducing Cytoplasmic Incompatibility (CI). These symbionts represent fascinating objects of study for evolutionary biologists, but also powerful potential biocontrol agents. Here, we assess the density dynamics of Wolbachia infections in males and females of the mosquito Aedes albopitcus, an important vector of human pathogens...
متن کاملArtificial triple Wolbachia infection in Aedes albopictus yields a new pattern of unidirectional cytoplasmic incompatibility.
Obligately intracellular Wolbachia bacteria infect numerous invertebrates and often manipulate host reproduction to facilitate the spread of infection. An example of reproductive manipulation is Wolbachia-induced cytoplasmic incompatibility (CI), which occurs commonly in insects. This CI has been the focus both of basic scientific studies of naturally occurring invasion events and of applied in...
متن کاملWolbachia Density and Cytoplasmic Incompatibility in Aedes albopictus: Concerns with Using Artificial Wolbachia Infection as a Vector Suppression Tool
The mosquito Aedes albopictusi is a competent vector of harmful human pathogens, including viruses causing dengue and chikungunya. Cytoplasmic incompatibility (CI) induced by endosymbiotic Wolbachia can be used to produce functionally sterile males that can be released in the field as a suppression tool against this mosquito. Because the available sexing methods are not efficient enough to avoi...
