Bio-pesticide extracted from garlic oils to control mosquito approach

Ovicidal, larvicidal, pupicidal, adulticidal and spatial repellency assays showed the broad activity of garlic oil against all Aedes aegypti life stages. Garlic oils are unique as insecticides in that they affect eggs, larvae and pupae, which commonly coexist at mosquito breeding sites. These results, together with its endurance in simulated field trials and the industrial production of garlic oil, highlight its suitability for integrated mosquito vector control programs.
