Popis: Background & objectives: Harmful effects of synthetic chemical insecticides including vectorresistance, environmental pollution and health hazards have necessitated the current significancein the search for plant-based insecticide products that are environmentally safe and effective toleishmaniases control. The insecticidal activity of Tagetes minuta Linnaeus (Asteraceae), Acalyphafruticosa Forssk (Euphorbiaceae) and Tarchonanthus camphoratus L. (Compositae) extracts wereinvestigated against Phlebotomus duboscqi Neveu Lemaire (Diptera: Psychodidae).Methods: The extracts were prepared from dried aerial parts soaked in methanol and ethyl acetatetwice until the filtrates became clear, filtered and dried out by rotary evaporation at 30–35oC. Thesolid extracts obtained were later prepared into 2.5, 5 and 10 mg/ml. Two millilitres of the solutionswere blotted on filter papers, which were dried overnight and placed into jars where adult sandflieswere aspirated. Males and females were assayed separately.Results & conclusion: The extracts had significant mortality (p
