An elusive endosymbiont: Does Wolbachia occur naturally in Aedes aegypti?

Abstract: Wolbachia are maternally inherited endosymbiotic bacteria found within many insect species. Aedes mosquitoes experimentally infected with Wolbachia are being released into the field for Aedes‐borne disease control. These Wolbachia infections induce cytoplasmic incompatibility which is used to suppress populations through incompatible matings or replace populations through the reproductive advantage provided by this mechanism. However, the presence of naturally occurring Wolbachia in target populations could in… Show more

“…In Grenada, C. quinquefasciatus was found to have an abundant population of Wolbachia among their bacterial microbiota (62.79% REA) while the A. aegypti population was not found to carry Wolbachia. This is consistent with other studies in which A. aegypti is rarely, if ever, infected with Wolbachia naturally, whereas C. quinquefasciatus is infected throughout its range and in most individual mosquitoes tested [89][90][91].…”

“…aegypti transfected with Wolbachia to replace the natural population to one that is refractory to several arboviruses [23]; II-the second approach is conducted by releasing male mosquitoes infected with Wolbachia seeking to induce CI and reduce the mosquito population [38]. To effectively deploy either strategy, researchers require precise information about any potential target mosquito species infected naturally by Wolbachia before and during any intervention, since it might have unexpected effects on the strategy employed [103].…”

“…aegypti, but the majority used only diagnostic amplicon-based molecular tools [51,[54][55][56][57][58] (Supplementary Material). Two studies went further and analyzed the presence of Wolbachia through maternal transmission and electron microscopy [45,52], but several criticisms have been made due to the lack of methodological consistency or experimental reproducibility issues [103]. Thongsripong et al, 2018 and Carvajal et al, 2019 detected Wolbachia belonging to supergroups C and D in Ae.…”
