Physicochemistry in established and potential larval mosquito microhabitats. a Physicochemistry in natural habitats of Cx. pipiens in the periphery of Frankfurt am Main, Germany, during September and October 2010. Temperature (°C), pH, conductivity (μS cm^-1) and dissolved oxygen concentration (mg l^-1) (mean ± SD) and respective Cx. pipiens abundance [# larvae: number of larvae (n = number of microhabitats)] are shown. Grey bars denote overall 95% confidence intervals. Key: 1, car tires; 2, vases; 3, rain barrels; 4, small reservoirs (bucket, plastic tarpaulin, pot, steel girder); 5, large reservoirs (metal and plastic tub, excavator shovel, water bowl); 6, dung discharge; 7, puddles; 8, ponds. b Spline curve of daily water temperature [mean ± SD] in 1 litre plastic cups logged from mid-May to end of July 2011. The cups representing potential mosquito habitats had been set up in shaded versus sunny localities in Frankfurt am Main
