“…Mosquitoes prefer breeding in sites with alkaline pH [11,73,74], which concurs with the findings of this study since most of the sites had alkaline pH levels except one negative site, which was slightly acidic. High pH levels in the sites were positively correlated with dissolved oxygen, biological oxygen demand, and nutrients.…”

Background. Since Anopheles mosquitoes which transmit and maintain the malaria parasite breed in the outdoor environment, there is an urgent need to manage these mosquito breeding sites. In order to elaborate more on the ecological landscape of mosquito breeding sites, the bacterial community structure and their interactions with physicochemical factors in mosquito larval habitats was characterised in Kwale County (Kenya), where malaria is endemic. Methods. The physical characteristics and water physicochemical parameters of the habitats were determined and recorded. Water samples were also collected from the identified sites for total metagenomic DNA extraction in order to characterise the bacterial communities within the breeding sites. Results and Discussion. Sites where mosquito larvae were found were described as positive and those without mosquito larvae as negative. Electrical conductivity, total dissolved solids, salinity and ammonia were lower in the rainy season than in the dry season, which also coincided with a high proportion of positive sites. Pseudomonadota was the most common phyla recovered in all samples followed by Bacteroidota and then Actinomycetota. The presence or absence of mosquito larvae in a potential proliferation site was not related to the bacterial community structure in the sampled sites, but was positively correlated with bacterial richness and evenness. Conclusion. Generally, the presence of Anopheles mosquito larvae was found to be positively correlated with rainy season, bacterial richness and evenness, and negatively correlated with electrical conductivity, total dissolved solids, salinity and ammonia. The findings of this study have implications for predicting the potential of environmental water samples to become mosquito proliferation sites.

Background The study of habitat preference and identification of malaria vector is one of the important steps in malaria control. Knowledge of local Anopheles mosquitoes capable of transmitting malaria parasites has contributed largely to the reduction in the menace caused by malaria infection. This present study examined the habitat nature and identified the species of Anopheles mosquitoes involved in malaria parasites transmission in the study area. Monthly collection and identification of the fourth larval stage was carried out from October 2018 to September 2019. Result The prevalence of An. gambiae complex and An. funestus larvae was 95.86 and 4.15%, respectively. The highest (14.17%) and the least (4.25%) number of larvae were collected in the month of November and May, respectively. Out of the total number of Anopheles mosquito larvae collected during the wet season, 69.77% of the larvae was collected from the clean habitat, while 30.23% was collected from the dirty habitats. During the dry season, the larvae dwell more in dirty aquatic habitat, with 64.74% of the larvae collected from the dirty habitats, while 35.27% was recorded from clean habitats. Statistically, there was no significant difference in the electrical conductivity when comparing both seasons (P = 0.19; X2 = 53.14). The average recorded electrical conductivity in dry and wet seasons were 350.76 µS/cm and 178.91 µS/cm, respectively. The pH recorded in dry and wet seasons were 6.78 and 7.04, respectively. There was no significant difference in the pH when both seasons were compared (P = 0.13; X2 = 54.89). The total dissolve solid where not significant different (P = 0.58; X2 = 13.35) when both seasons were compared. The temperature (P = 0.04; X2 = 43.54) and dissolve oxygen (P = 0.00; X2 = 30.09) were significantly different comparing dry and wet seasons in all the habitats where the immature stages of Anopheles mosquitoes were collected. Conclusion The study revealed major vector of malaria parasite in the study location, also the pattern of their breeding during dry and rainy season which is influenced by some selected ecological factors.
