摘要：Context: We modified conventional metal body evaporative desert coolers by covering the water sump with fabricated metal mesh.Aedes mosquito breeding in these modified desert coolers was then tested during dengue transmission season.Aim: This study was carried out with the aim of providing an effective modification which can be carried out locally in evaporative metal body desert room coolers,to prevent Aedes mosquito breeding.The authors also compared the effectiveness of such desert coolers mounted with fabricated metal mesh against the standard National Centre for Disease Control,mosquito proof coolers (NCDC-MPC).Settings and Design: This study was carried out from October 2015 to 2016 in a large military cantonment area of North India.The data collection for larval breeding was done during late summer and monsoon months,namely May–October 2016.Subjects and Methods: Conventional metal body evaporative desert cooler was modified by covering its sump water tank with a fine mesh.These modified coolers were then monitored for larval breeding and compared with the NCDC-MPC,and conventional nonmodified routinely used desert coolers.Statistical Analysis Used: A database was created in MS Excel and observations were recorded analyzed and tabulated.Results: No breeding was detected in the NCDC coolers and the coolers mounted with fabricated metal mesh.Conclusion: The conventional desert cooler locally modified by mounting a fabricated metal mesh to cover sump water tank of the cooler,was found to be effective in preventing Aedes breeding.It offers the advantage of simplicity,low cost,and improved availability.
