Objective: To explore the effects of different chemical larvicides, bioinsecticides and insect\udgrowth regulators against the West Nile vector Culex pipiens (Diptera: Culicidae) (Cx. pipiens)\udin Saudi Arabia.\udMethods: We tested seven commercial mosquito larvicides, including classic cyfluthrin,\uddiazinon and propoxur, bioinsecticides Bactilarvae and Tracer 24%, and insect growth\udregulators Baycidal and Sumilarv. LC50 and LC90 values were calculated in laboratory\udconditions using probit analysis.\udResults: Concerning chemical insecticides, the highest larval mortality was observed for\uddiazinon, with LC50 = 0.352 3 mg/L, followed by propoxur and cyfluthrin. The bacterial\udinsecticide Tracer was more effective than Bactilarvae (LC50 = 0.008 7 mg/L and 0.011 7 mg/L,\udrespectively) by 1.37 folds. Furthermore, Cx. pipiens larvae were more susceptible to insect\udgrowth regulators Baycidal (IC50 = 0.0004 mg/L) if compared to Sumilarv (IC50 = 0.0029 mg/L)\udby 7.25 folds.\udConclusions: Overall, this research added basic knowledge about the effectiveness of seven\udmosquito larvicides with different mechanisms of action as potential candidates for the control\udprograms of Cx. pipiens mosquito populations in Saudi Arabia
