Abstract: 

Pyrethroid – impregnated bednets have been shown to be one of the most promising tools that have emerged in recent years to control malaria. Mosquitoes may be physically irritated by pyrethroids, reducing the time searching for blood meals, or driving them away. Permethrin impregnated nets also may deter a proportion of mosquitoes from entering houses. Irritnat effect of nets treated with 200 mg and 500 mg permethrin/m2 on susceptible and resistant genotypes of Anopheles stephensi was studied using the modified W.H.O. provisional technique. The W.H.O irritability tests were not used in the present study. Irritability tests were carried out in a W.H.O plastic biossay cone. Three days old unfed, females were tested individually or in group of five mosquitoes. When female mosquitoes were confined in bioassay cones on treated netting, the resistant strain of A. stephensi showed significantly less irritability (scored on the time until first flight take-off) in response to each dose as compared with the susceptible strain and FI hybrids. The higher dose provoked more irritation of each genotypes, this could cause lower knockdown and kill rates which this dose could produce with each genotype. From the results of this stydy it could be concluded that a dose of 200mg/m2 of permethrin impregnated into bednets is preferable to 500mg/m2 for malaria control.
