The repellent activities from the essential oil of S. aromaticum against C. maculatus were evaluated using the area of preference method described by . The test area consisted of 11.0cm Whatman No. 1 filter paper cut in halves and 1 ml of each concentration (100, 200, 300 and 400 ppm) was applied uniformly to half -filter paper disc with a micro syringe. The other half filter paper was treated with 1ml of ethanol (control) and the half discs were air-dried for 10 minutes to allow the solvent to evaporate completely. Full filter paper was re-made by attaching treated halves to untreated halves of the same dimensions with cello tape and each placed in a Petri dish with ten adult beetles released separately at the centre of each filter paper disc. The Petri dish was covered and treatments (concentration) were arranged in a Completely Randomized Design (CRD) in four replications. The number of insects present on the controls (untreated) and treated half discs were recorded after 1 hour and 2 hours of exposure. Repellence (PR) for each replicate was estimated as; PR = (Nc -Nt)x 100 .
