Studies on the production of plant-based pest control strategies have been growing in recent years. Origanum (Lamiaceae) species are important medicinal aromatic plants and many studies conducted their biological activities. This study was to determine repellent effects plant essential oils extracted from four different species: O. onites, vulgare var. hirtum, verticium onites × vulgare, agains...
