Essential Oils From Five Local Plants: An Alternative Larvicide for Anopheles gambiae s.l. (Diptera: Culicidae) and Aedes aegypti (Diptera: Culicidae) Control in Western Burkina Faso

Introduction Malaria and dengue are two main vector-borne infectious diseases transmitted by Anopheles gambiae Aedes aegypti , respectively, in tropical subtropical regions. The concern for environmental safety the increasing development of resistance to chemical arthropod vectors raises interest search botanicals such as essential oils (EOs) that can be used vector control. Methods Larvicidal bioassays were performed according WHO standard methods using Ae. An. larvae collected from Bobo-Dioulasso Kou Valley (VK), areas located Houet Province western Burkina Faso. Kisumu Bora bora, susceptible strains controls. OEs extracted leaves five aromatic plants, Cymbopogon citratus nardus Eucalyptus camaldulensis Lippia multiflora Ocimum americanum naturally growing Faso tested. pyriproxyfen was a positive Results As result, lethal concentrations (LC 50 ) VK ranged 41.9 103.8 ppm 39.5 138.1 ppm, respectively. LC 90 values, they 74.6 311.3 90.2 328.9 VK. Among EOs tested, L. showed highest activity against all larvae. No difference terms values found between control on It is not case populations, where remains most toxic. Overall, populations tested compared populations. Conclusion Our study furthers our knowledge larvicidal part opens new avenues their putative use strategies.
