Abstract

In recent years, plant essential oils have received a great deal of attention as pest control agents in control of storage pests.In this study, the essential oils were extracted from the horsemint, Mentha longifolia L. leaves through hydrodistillation. The essential oil was evaluated for contact and fumigant toxicity against 1-7 day-old adults of the confused flour beetle (T. castaneum). The probit analysis of data demonstrated that fumigant toxicity of Mentha longifoliaoil on T. castaneum (LC50=0.872 μL/cm2) was significantly more than contact toxicity (LC50=27.11 μL/cm2). The results showed high fumigant toxicity of the essential oils against adults of the confused flour beetle.
