Control of mosquito breeding using wood scrapings treated with neem oil

Wood scrapings were given shape of a ball and soaked in 5, 10 and 20% neem (Azadirachta indica) oil diluted in acetone. Control of Anopheles stephensi and Aedes aegypti breeding in water storage overhead tanks (OHTs) with the application of these balls was achieved for 45 days. Two balls soaked in 5% neem oil produced the best results among other concentrations tested.
