Abstract

Indoor and outdoor ULV treatments for control of malaria and arbovirus vectors demonstrated that technical malathion applied by knapsack sprayers gave long-term control of both Anopheles and Aedes species. Post-treatment indoor landing rates of Anopheles species remained at 0.2/man-night for 14 weeks with a small increase recorded only in the 20th week. Cement walls retained a slightly higher insecticidal effect than mud walls. High droplet densities were also found on floors and ceilings. This technique was shown to be inexpensive, fast and highly flexible.
