INTRODUCTION In recent years, there is an increasing trend in research of essential oils extracted from various herbs and aromatic plants due to the continuous discoveries of their multifunctional properties other than their classical roles as food additives and/or fragrances. New properties of many essential oils, such as antibacterial, antifungal, antioxidant, and anti-inflammatory activities have been found and confirmed (Aruoma et al, 1996; Hammer et al, 1999; Güllüce et al, 2003). The pharmacological properties of essential oils extracted from plants have received the greatest interest of academic institutes and pharmaceutical companies (Ryman, 1992; Loza- Tavera, 1999; Courreges et al, 2000; Carnesecchi et al, 2002 and Salim et al, 2003). On the other hand, the insecticidal activities of essential oils are more favored by agricultural scientists and agri-business. Consequently, many investigation and new findings have significantly prompted and expanded novel applications of essential oils which are now been widely used as natural insecticides, cosmeceuticals, and aroma therapeutic agents.
