COMPARATIVE STUDY OF TOXICITY OF SOME ESSENTIAL OILS TO LARVAE OF THREE MOSQUITO SPECIES
AbstractThe toxicity of the essential oils from the leaves of Lantana camara L., Eugenia uniflora L. and fruits of Aframomum daniellii K. Schum to the fourth instar larvae of Aedes aegypti, Anopheles gambiae and Culex pipiens fatigans was investigated. The results indicated that 0.02-0.04% of the oils produced 90-100% mortality on the larvae of all the three mosquitoes. The oils from E. uniflora and L. camara at a concentration of 0.02% were more toxic to Culex pipiens fatigans and Aedes aegypti (producing 100% mortality at 24h.) than Anopheles gambiae.
Key Words: Lantana camara, Eugenia uniflora, Aframomum daniellii, essential oils, toxicity, mosquito larvae.
