Abstract: In laboratory, 20mg ai/m² and 10mg ai/m² clocythrin-impregnated bednets caused the average mortalities of 80.1% and 74.0% on laboratory-bred An.sinensis within one year respectively.In experimental hut trials, the average mortalities of An.sinensis and Cx.tritaeniorhynchus were 72.5% and 72.2% with 40 mgai /m^{2 in clocythrin - treated bednets, 168 days after impregnation, and were 45.0% and 38.6% with the semi-closed treated bednets respectively.By comparison with the control hut, the intact closed treated bednet reduced the feeding rate by 56.7% for An.sinensis and by 43.3% for Cx.tritaeniorhynchus.The semi-clased treated bednets reduced the feeding rate by 27.4% and by 32.3% respectively.Meanwhile, 20mg ai/m2 clocythrin-impregnated bednets caused 49.8% average mortality of An.sinensis and 53.4% average mortality of Cx.tritaeniorhynchus within 14 days after treatment, and it reduced the feeding rate by 60.3% for An.sinensis and by 69.5% for Cx.tritaeniorhynchus.And the average mortalities of 30.3% and 44.3% were obtained with the semi-closed treated bednets respectively, 22 days after impregnation.The feeding rate was reduced by 30.0% for An.sinensis and by 36.5% for Cx.tritaeniorhynchus.}
