BackgroundVarious chemical control methods have adopted in anti-malaria interventions. Indoor residual spraying (IRS) has been proven as a candidate in elimination program. On the other hand, resistance to multiple insecticides was implicated as a concern issue in these polices. Pesticides should be evaluated to identify probable resistant and make decision to choose a technique against vectors.MethodsIn this cross-sectional study, Bioassay test applied on lambdacyhalothrin WP 10% (0.05 mg a.i. /m2) and deltamethrin WP 5% (0.05 mg a.i./m2) on two surfaces (cement and plaster) against adult mosquitoes of Anopheles stephensi according to WHO criteria to measure the residual activity in Saravan county, southern Iran. Overall, 3960 mosquitoes was used in our research. The mortality rates of An.stephensi Liston (Diptera: Culicidae) measured between selected surfaces and insecticides in several times. Data analyzed by Mann-Whitney (nonparametric test) using SPSS v22 statistic software.ResultsThis paper illustrated that maximal course of residual efficacy was about 3 months. No statistically significant different was exhibited between type of surface within mortality rates of An. Stephensi (P = 0.724) but lambdacyhalothrin has more durability than deltamethrinConclusionsWe established that lambdacyhalothrin can be used into control and elimination setting of malaria with two rounds of spray at an interval of 3-4 months in south of Iran
