Abstract: The present paper reports on the effectiveness of a repellent coating for the first time;.The repellent coating was made by combining DETA (N,N-diethyl-meta-toluanide) with slow-releasing reagent.With this coating employed in the laboratory against Aedes aegypti,the rate of blood-sucking was 3.9-9.5% and the rate of protection was 88.9-95.3% for 1-720 days.During 1-77 days' field trial,the RPI (Relative Population Index) was 0-8.98% in the day-time and 0.74-17.15 during the night-time against Anopheles sinensis,Culex pipiens pollens and Culex tritaeniorhynchus.It is concluded that the repellent coating is effective against mosquitoes,safe and prolongs the protection time following exposure to mosquitoes.
