Objective: To study the larvicidal activity of essential oils of two aromatic and medicinal\udplants, Citrus aurantium (C. aurantium) and Citrus sinensis (C. sinensis) (Rutaceae) cultivated\udin North Eastern Morocco, against the larvae of the malaria vector Anopheles labranchiae (An.\udlabranchiae) (Diptera: Culicidae).\udMethods: Biological tests were realized according to a methodology inspired from standard\udWorld Health Organization protocol. The mortality counts were made after 24 h and LC50 and\udLC\ud90 values were calculated.\udResults: Bioassays revealed that these oils had remarkable larvicidal properties. The minimum\udlevels necessary to achieve 100% mortality of An. labranchiae larvae were evaluated at\ud160 mg/L for C. aurantium and 640 mg/L for C. sinensis. Essential oil of C. aurantium\udremained the most efficient (LC50 = 22.64 mg/L, LC90 = 83.77 mg/L), while those of C.\udsinensis was the least (LC50 = 77.55 mg/L, LC90 = 351.36 mg/L).\udConclusions: These results suggest that the essential oils isolated from Citrus plants have the\udpotential to be used as an ideal ecofriendly approach for the control An. labranchiae
