dc.description.abstractThe repellency of the essential oil of the shrubCleome monophylla (Family: Capparidaceae) and identified constituents of the oil were evaluated against the livestock tick,Rhipicephalus appendiculatus and the maize weevil,Sitophillus zeamais. In a tick climbing repellency bioassay, the oil ofC. monophylla exhibited repellency which, at the highest dose, was comparable to that of the commercial arthropod repellent N,N-diethyl toluamide (DEET). In a Y-tube olfactometer bioassay,C. monophylla oil showed higher or comparable repellency againstS. zeamais relative to DEET at all the doses tested. 14 Compounds were identified in theC. monophylla oil by GC, GC-MS and coinjection with authentic samples. Terpenolene was found to occur in largest quantity (14%) followed by 1-α-terpeneol (10%), pentacosane (9%), (α+β)-humulene (8%), phytol (5%) and 2-dodecanone (4%). The most repellent components againstR. appendiculatus andS. zeamais were 1-α-terpeneol and 2-dodecanone. The overall pattern of repellency activity of theC. monophylla constituents with respect to the two arthropods was, however, different. The potential ofC. monophylla in tick and maize weevil control is discussed.en_US
