Susceptibility of Two Different Strains of Aedes aegypti (Diptera: Culicidae) to Plant Oils

Abstract The toxicity of 11 oils extracted from plants commonly grown in the Himalayan region was studied using larvae of two Aedes aegypti (L.) strains. A strain from Liverpool, England, was highly susceptible to these oils. The LC50 values were much higher in a local laboratory strain. Daucus carota L. oil was highly toxic in both strains. Differences in the susceptibility of these strains to the action of the test oils and their potential use in integrated pest management are discussed.
