Abstract:		"Experiments were carried out to investigate the response of two tick species Rhipicephalus pulchellus Gerstaker, 1873 and Rhipicephalus appendiculatus Neumann, 1901 to three different extracts (acetone, aqueous and oil) of the dried leaves of Calpurnia aurea (Aiton) Benth in both an inverted glass tube and a dual choice T-olfactometer. The oil extract at 50 and 100mg/ml attracted 46.7% and 65.9% of R. appendiculatus, respectively, in the inverted glass tube assay, which was comparable to 47.8% of the attraction-aggregation-attachment pheromone (AAAP) used as positive control. At a dose of 100mg/ml the oil extract attracted 52.4% of R. pulchellus in the T-olfactometer bioassay. The relative attraction of both tick species to plant extract was also tested in semi-field plot experiments using a trap baited with different concentrations of emulsifiable extract of C. aurea. A dose of 100mg/ml attracted 52.2% of R. pulchellus and 44.4% of R. appendiculatus from a distance of 1m while 14.4% of R. pulchellus and 12.2% of R. appendiculatus were attracted from 5m distance at the same dose. Addition of CO(2) to the plant extract-baited-trap at the dose of 100mg/ml increased the range of attraction of adult R. pulchellus (44.4% from 5m distance) and up to 33.3% of adult R. appendiculatus tick from a distance of 4m. The results of this study suggest that extracts from C. aurea can potentially be used as baits in a trap for the control of ticks in the field"
