Abstract: Objective To observe the residual effects of Fendona and Demand impregnated bednets for pest control in peacekeeping area in Sudan. Methods Fendona (30 mg·ai/m²) and Demand (20 mg·ai/m²) was used to impregnate bednets before going abroad. Observating the dead number of mosquitoes, flies and other insects on the bednets one time every three days. Results The bednets impregnated by Demand has good residual effect for mosquitoes, flies and other insects after 27 days. The residual effect of bednets impregnated by Fendona appeared obviously decline after 21 days. Compared the dead number of vector on bednets impregnated by Demand and Fendona, there was significant difference in statistics on 21 days on mosquitoes (Z=2.373, P=0.015) and on 24 days on flies and other vector (Z=1.783,P=0.047;Z=2.096,P=0.026,each). Conclusion Bednets treated by two pesticides are efficient for vector control, but Demand at 20 mg·ai/m² is better than Fendona at 30 mg·ai/m² because Demand can last more residual effects time.
