“…Although it has been documented that Anopheles mosquitoes prefer to breed in fresh and clean waters (Manguin, 2013), the obtained results demonstrate their tolerance to wide ranges of temperature, pH and conductivity (Table 2). This confirms the previous studies of Emidi et al (2017) and Amawulu et al (2020), which found that these mosquitoes breed in a great diversity of habitats: from fresh waters to polluted ones, including those with high saline inputs such as coastal lagoons. Likewise, the detection of these larvae in waters close to pH 4 shows that mosquito mortality does not necessarily occur below pH 4.5 as suggested by Tiimub et al (2012).…”

Galicia, located in the northwestern part of Spain, has a great number and variety of aquatic ecosystems where mosquitoes can breed. Despite the sanitary relevance of these insects, studies on mosquito populations in the region are still scarce. The field research was carried out in 48 sampling points (27 continental lagoons, 12 coastal lagoons and 9 temporary ponds) throughout the entire Galician territory. The samples were collected intermittently and seasonally through different water quality monitoring projects between 2001 and 2017. More than 1500 mosquito larvae belonging to 10 species of five genera (Aedes, Anopheles, Coquillettidia, Culex and Culiseta) were identified. Anopheles (Anopheles) maculipennis s.l. Meigen was the most widely distributed species in the study, being especially dominant in rural areas. In contrast, Culex (Culex) pipiens Linnaeus and Culex (Culex) theileri Theobald showed a preference for breeding in urban areas. New contributions to the knowledge about the larval ecology and distribution of these mosquito species are made throughout this study, including information about the tolerance of each species to water parameters (temperature, pH, dissolved oxygen and conductivity). Likewise, the relationship between culicid diversity and the habitat characteristics of the breeding sites (water body type, climate and level of anthropization) is discussed.

“…Kitching [18] gave some of the breeding sites of various mosquito genera in his study. Various authors have also reported physico-chemical parameters where mosquito larvae can develop and survive in Nigeria [19,20,21]. The higher population of Culex than Anopheles in this study was contrary to the findings of Amaechi et al [22] where Anopheles mosquitoes were reportedly higher in population density than Culex.…”

Understanding the relationship between climate variables and mosquito abundance is an important factor to determine parasite activity levels and disease risk since various mosquito genera are vectors of parasitic diseases. This necessitated the investigation of relationship between climatic variables and mosquito abundance in Ekiti State, Nigeria with reference to six selected communities. Adult mosquitoes were collected indoor for twelve months in these communities using light traps. The abundance of collected mosquitoes was related with climatic variables (rainfall, relative humidity and temperature). One thousand two hundred and seventeen (1217) adult mosquitoes were collected indoor in all the communities. The population of the mosquito genera was significantly higher (P=0.01) in rainy season than dry season. Average rainfall showed a strong relationship (R2= 0.751) with Anopheles abundance but relationship was weak for both Culex (R2= 0.236) and Aedes (R2= 0.042). The relationship of relative humidity and average temperature with abundance of mosquito genera was generally weak. Since the abundance of mosquito genera was higher in all the communities during rainy season than dry season it will be more appropriate to control mosquitoes in the communities during the rainy season.

“…Although electrical conductivity, total dissolved solids, salinity, and ammonia were significantly lower in the rainy season than in the dry season, there was no evidence that these variables could influence the mosquito larval presence or absence at the sites throughout the two seasons. However, it is notable that the levels recorded for conductivity, total dissolved solids, salinity, and ammonia in both seasons were favourable for mosquito breeding, which was comparable to the findings of a study conducted on a Nigerian university campus [ 72 ]. The low levels of these parameters during the rainy season can be attributed to the dilution of environmental surface water by rainwater [ 65, 71 ].…”

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.
