Composition chimique et effet Acaricide des huiles essentielles des feuilles de Chenopodium ambrosioides et de Eucalyptus saligna sur les tiques (Rhipicephalus lunulatus) au Cameroun.

CHEMICAL COMPOSITION AND ACARICIDE EFFECT OF THE ESSENTIAL OILS OF LEAVES OF CHENOPODIUM AMBROSIOIDES AND EUCALYPTUS SALIGNA ON TICKS (RHIPICEPHALUS LUNULATUS) OF WEST AFRICAN DWARF GOAT IN WEST CAMEROON Summary The chemical composition and the acaricide effect of the essential oils from leaves of Chenopodium ambrosioides and Eucalyptus saligna was evaluated on Rhipicephalus lunulatus in the Laboratory of Environmental and Applied Chemistry of University of Dschang in west Cameroon. Five doses of each essential oil (0.000; 0.157; 0.314 and 0.629 µl/cm2) in four replications were used. Each replication was made up of ten ticks in Petri dish with filter paper on the bottom and uniformly impregnated with the product. The results of this study indicate that essential oils studied are toxic to Rhipicephalus lunulatus ticks. Significant (
