Abstract
ObjectiveTo investigate the insecticidal activity of the essential oil of Thymus transcaspicus (T. transcaspicus) against Anopheles stephensi (An. stephensi).MethodsAn. stephensi were exposed to 31, 63, 125 and 250 µg/L of essential oil of T. transcaspicus for 24 h.ResultsThe most toxicity was observed at 250 µg/L of essential oil with the LC50 values of 134.1 µg/L after 24 h.ConclusionsThe essential oil of T. transcaspicus exhibited strong insecticidal activity against An. stephensi which can be attributed to its constituent especially carvacrol and thymol phenolsKeywords
