“…All four bacterial isolates could tolerate up to 4% NaCl concentration of the growth medium. All of the four isolates showed a wide range of pH tolerance (5)(6)(7)(8)(9)(10)(11), although they exhibited maximum amount of growth between pH 7.5-9.5 of the media (Fig 14). Growth of the bacterial isolates in the culture medium at different temperatures revealed that they could tolerate temperature range 15˚C-45˚C, although their growth became increased at 30˚C-35˚C (Fig 15).…”

“…After the incubation period, amount of bacterial growth was recorded by taking optical density (O.D) at 600 nm. For pH tolerance test bacterial isolates were inoculated separately in sterilized nutrient broth having varying pH(5)(6)(7)(8)(9)(10)(11) and were incubated in B.O.D. shaker incubator for 24 h at 32±1˚C.…”

Mosquitoes prefer diverse water bodies for egg laying and larval survival. Present study was performed with an objective to characterize physico-chemical properties and microbial profiling of breeding habitat water bodies of Anopheles subpictus mosquitoes. A field survey was accomplished to check the presence of An. subpictus larvae to record per dip larval density in various breeding habitats throughout the year. Physico-chemical and bacteriological properties in relation to mosquito oviposition were assessed. Dissolved oxygen content, pH and alkalinity were found to have major impacts and ponderosity on the prevalence of An. subpictus larvae. Larval density showed significant positive correlation with dissolved oxygen content of water and significant negative correlation with pH and alkalinity of habitat water. Comparatively higher population (cfu/mL) of Bacillus spp. competent with starch hydrolyzing and nitrate reducing properties were recorded all the breeding habitat water bodies of An. subpictus. Higher amplitude of anopheline larvae was portrayed during monsoon and post-monsoon season in clear water with an inclining trend to high dissolved oxygen content and neutral pH. B. cereus, B. megaterium, B. subtilis and B. tequilensis prevalent in all habitat water bodies were marked as oviposition attractants of gravid An. subpictus mosquitoes. Microbial population played key roles in the modulation of physico-chemical parameters of habitat water with a view to enhance its acceptability by gravid mosquitoes in relation to their oviposition. Better understanding of the interactions along with the control of oviposition attractant bacterial strains from mosquito breeding habitats might contribute to the vector management programme.

Blue-green spaces (BGSs), urban areas characterized by the presence of vegetation and or water, and infrastructure form a potential solution for public health threats from increasing urbanization. We conducted a meta-analysis to test the hypothesis that blue-green spaces increase the abundance of nuisance and vector mosquito species compared to non-greened urban areas. After screening 7306 studies published since 1992, we identified 18 studies containing sufficient data from both traditional urban areas and BGSs. We found no significant difference in mean abundance of all mosquito taxa in three genera (Aedes, Culex, Anopheles) when comparing blue-green spaces and non-greened urban spaces. Similarly, a separate analysis of each individual genera found no significant differences. An analysis of the taxa by larval habitat guilds found no differences for container-breeding mosquitoes. Flood-water species tended to be more abundant in blue-green spaces, but the differences were not significant. The individual taxa of Aedes albopictus and the Culex pipiens complex showed no differences between blue-green and urban spaces, while the abundance of Aedes aegypti was significantly higher in traditional urban spaces. Due to the variety existing between and among the several types of blue-green spaces, further studies comparing each unique type of blue-green space or infrastructure will be necessary to draw conclusions regarding the influence of each structure on for urban mosquito communities.

Climatic variables like temperature, rainfall and humidity play an important role in dynamics of mosquitoes. But the effect of climate change during urbanization on Anopheles mosquitoes has not been studied. The objective of present study was to explore the effects through the changes in climate variables of urbanizing Ghaziabad District, India on malaria vector Anopheles sp., particularly Anopheles stephensi (Liston) and An. culicifacies sensu lato (Diptera: Culicidae). The study was conducted in urban, rural and peri-urban parts seasonally from April 2014 to October 2016. Association between climate variables, malaria and Anopheles abundance was studied through Pearson's correlation and Principal Component Analysis (PCA). Results showed that pollution in water bodies and low rainfall has decreased the abundance of An. culicifacies s.l in rural and peri-urban whereas An. stephensi L has increased in rural areas. In urban and peri-urban areas rainfall has lesser influence on An. stephensi hence species breeds throughout the year easily whereas the humidity supports both the vectors. The role of temperature was found to be uncertain, although minimum temperature found to influence vector density as indicated by cluster analysis in the present study.
