The use of larvaoils for the eradication of the malaria vector

Abstract

Oil samples which include diesel, kerosene, fresh engine oil and used engine oil were collected from fuel stations in Kano metropolis. Oil blends were prepared and analyzed for density, viscosity, surface tension, spreading diameter on water surface and extermination time. Five blends A:B (Kerosene: Diesel) 250:20(cm³);A:B (Kerosene: Diesel) 250;40(cm³); B:A (Diesel: Kerosene) 250:80(cm³) B:A (Diesel: Kerosene) 250: 60(cm³) and D:B (Fresh Engine Oil: Diesel) 250:60(cm³) with spreading diameter of 9cm, 8cm, 8cm, 9cm and 8cm and extermination time of 20mins, 26mins, 28mins, 38mins and 46mins respectively were found to spread effectively on water surface and exterminate mosquito larvae by asphyxia.

Keywords: Density, Viscosity, surface tension, spreading diameter, extermination time.
