Abstract
This research offers a comprehensive exploration of the microbial communities associated with vector mosquitoes from South Korea. Aedes albopictus, Anopheles sinensis, and Culex molestus are vectors of pathogens, and understanding the intricacies of their microbiome profile is paramount for unraveling their roles in disease transmission dynamics. In this study, we characterized the microbiome of the midguts of adult female vector mosquitoes collected from different locations in South Korea. After DNA extraction from dissected mosquito midguts, we used the Illumina MiSeq next-generation sequencing to obtain sequences spanning the V4 hypervariable region of the bacteria 16S rRNA. Morphological and molecular characterization using 506-bp mitochondrial 16S rRNA was used to identify the mosquito species before amplicon sequencing. Across the three vector mosquitoes surveyed, 21 bacteria genera belonging to 20 families and 5 phyla were discovered. Proteobacteria and Bacteriodota were the major phyla of bacteria associated with the three mosquito species. There were significant differences in the gut microbiome genera composition between the species and little variation in the gut microbiome between individuals of the same mosquito species. Wolbachia is the most dominant genus in Aedes while Aeromonas, Acinetobacter, and unassigned taxa are the most common in An. sinensis. In addition to that, Chromobacterium, Chryseobacterium, and Aeromonas are dominant in Cx. molestus. This study sheds light on the complex interactions between mosquitoes and their microbiome, revealing potential implications for vector competence, disease transmission, and vector control strategies.

Abstract
The midgut microbial community composition, structure, and function of field-collected mosquitoes may provide a way to exploit microbial function for mosquito-borne disease control. However, it is unclear how adult mosquitoes acquire their microbiome, how the microbiome affects life history traits and how the microbiome influences community structure. We analyzed the composition of 501 midgut bacterial communities from field-collected adult female mosquitoes, including Aedes albopictus, Aedes galloisi, Culex pallidothorax, Culex pipiens, Culex gelidus, and Armigeres subalbatus, across eight habitats using the HiSeq 4000 system and the V3-V4 hyper-variable region of 16S rRNA gene. After quality filtering and rarefaction, a total of 1421 operational taxonomic units, belonging to 29 phyla, 44 families, and 43 genera were identified. Proteobacteria (75.67%) were the most common phylum, followed by Firmicutes (10.38%), Bacteroidetes (6.87%), Thermi (4.60%), and Actinobacteria (1.58%). The genera Rickettsiaceae (33.00%), Enterobacteriaceae (20.27%), Enterococcaceae (7.49%), Aeromonadaceae (7.00%), Thermaceae (4.52%), and Moraxellaceae (4.31%) were dominant in the samples analyzed and accounted for 76.59% of the total genera. We characterized the midgut bacterial communities of six mosquito species in Hainan province, China. The gut bacterial communities were different in composition and abundance, among locations, for all mosquito species. There were significant differences in the gut microbial composition between some species and substantial variation in the gut microbiota between individuals of the same mosquito species. There was a marked variation in different mosquito gut microbiota within the same location. These results might be useful in the identification of microbial communities that could be exploited for disease control.

Abstract
The mosquito gut is divided into foregut, midgut, and hindgut. The midgut functions in storage and digestion of the bloodmeal. This study used light, scanning (SEM), and transmission (TEM) electron microscopy to analyze in detail the microanatomy and morphology of the midgut of nonblood-fed Anopheles aquasalis females. The midgut epithelium is a monolayer of columnar epithelial cells that is composed of two populations: microvillar epithelial cells and basal cells. The microvillar epithelial cells can be further subdivided into light and dark cells, based on their affinities to toluidine blue and their electron density. FITC-labeling of the anterior midgut and posterior midgut with lectins resulted in different fluorescence intensities, indicating differences in carbohydrate residues. SEM revealed a complex muscle network composed of circular and longitudinal fibers that surround the entire midgut. In summary, the use of a diverse set of morphological methods revealed the general microanatomy of the midgut and associated tissues of An. aquasalis, which is a major vector of Plasmodium spp. (Haemosporida: Plasmodiidae) in America.
