Abstract

The potential for gut microbiota to impede or enhance pathogen transmission is well-documented but the factors that shape this microbiota in mosquito vectors are poorly understood. We characterized and compared the gut microbiota of adult females of Culex restuans (Theobald; Diptera: Culicidae) from different parents. Cx. restuans larvae from nine field-collected egg rafts were reared on a common diet and gut microbiota of newly emerged adult females characterized by MiSeq sequencing of the V4 hypervariable region of the 16S rRNA gene. Bacterial diversity and evenness in individuals from one egg raft were significantly lower compared to those of three of the other eight egg rafts. The gut microbiota of adult females reared from seven of the nine egg rafts clustered together suggesting that individuals from most egg rafts had similar profiles of gut microbiota. These findings suggest that the microbiota of adult females from the same parents do not differ appreciably from the microbiota of adult females from different parents. However, additional studies using mosquitoes separated by geographic distances greater than those studied here and estimating the genetic distances between populations from different egg rafts are needed to provide further insights into the influence of host genetics on gut microbiota. Also worthwhile are studies evaluating how individuals from different egg rafts and harboring different gut microbiota compare in relation to vector competence for different pathogens.
