Objective: To assess the chemical composition and mosquito larvicidal potentials of essential oil of wild chive (Allium schoenoprasum L.) against Anopheles stephensi. Methods: In the search for an environmentally safer alternative mosquitoes control, the larvicidal efficacy of essential oil obtained from the leaves of Allium schoenoprastum L. against Anopheles stephensi was determined. The composition of chive essential oil was analyzed by gas chromatography-mass spectrometry. Results: In toxicity assays, the essential oil demonstrated substantial larvicidal activity against larvae of Anopheles stephensi with LC50 and LC90 values of 2.60, and 7.31 ppm after 24 h of exposure, respectively. Gas chromatography-mass spectrometry analysis of chive essential oil identified 35 components representing more than 97.31% of the total essential oil. The main constituents were sulfur compounds, including diallyl trisulfide (13.72%), 2-ethyl[1,3]dithiane (8.93%), allyl methyl trisulfide (8.77%), and trimethylene trisulfide (6.64%), respectively. Conclusions: This study demonstrated that wild chive essential oil has a rich source of eco-friendly bioactive compounds for use as a mosquito larvicide. The main reason for its extraordinary properties may be related to the high percentage of sulfur compounds.
