The residual effect of four known insecticides prepared in olive oil and sprayed on cement plastered walls was estimated against the Egyptian strain of Phlebotomus papatasi (Scopoli). The results showed that propoxur reduced the number of the tested sandflies to 16.5%, 24.1%, 46.4%, 53.4% and 76.7%, 75 days post treatment after an exposure time for 5, 10, 15, 20 and 30 minutes. Permethrin caused zero, 17.5%, 25.0%, 41.4% and 51.9%; malathion caused 4.3%, 10%, 26.7%, 35.9% and 49.1% and B H C caused zero, 10%, 30%, 36.3% and 48.1% for the same exposure time respectively. This indicated that propoxur had the highest residual effect and B H C had the lowest one. The results were discussed in relation to leishmaniasis control.
