| Summary: | Filariasis is caused by microfilariae parasites transmitted through mosquitoes, one of which is Mansonia spp. Environmental characteristics are crucial component for vector control in handling filariasis because they indicate mosquitoes’ range of survival. This study aimed to determine the environmental characteristics in the abundance of Mansonia spp. This study was conducted in two lowland areas located in Sedang and Muara Sugih Village, Indonesia, April 2017-April 2018. Environmental characteristics were determined by thermometers and sling hygrometers, and sampling for physical and chemical properties of water. Sedang Village had larger quantity of Mansonia spp variances compared to Muara Sugih, with 6 species and 5 species found respectively. Muara Sugih was slightly higher in temperature and humidity. Sedang water had higher turbidity, higher temperature, higher pH, lower BOD-COD, lower TDS-TSS, with higher coliform counts. Sedang dominant land utilization was plantations, while Muara Sugih was rice field. The dominant aquatic plant in Sedang was Pistia stratiotes and Muara Sugih was Oryza sativa. Differences in temperature, humidity, water parameters, aquatic plants, and land utilization factors resulted in discrepancy of Mansonia spp abundance.
