Abstract: Field trials on the control of An.dirus using deltamethrin-impregnated door and window curtains with big holes were conducted.The dose of the insecti cide employed was 25mg/m² and satisfactory results have been obtained.The average density of An.dirus in the experimental villages was reduced by 71.2% four months after the trial and the average mosquito density in the houses at daytime was reduced by 94.9%.Sampling tests of the deltamethrin-impregnated door and window curtains were also completed as described by Hossain & Curtis,the results showed that the mortality rate of An.dirus was 92.4% 140 days after the trial and their bloodsucking activities were obviously affected.
