New Nano-Biopesticide Formulation of Mentha piperita L. (Lamiaceae) Essential Oil Against Stored Product Red Flour Beetle Tribolium castaneum Herbs and its Effect on Storage

In recent years, providing new formulations such as nano-emulsions have been widely used for the target delivery, and enhanced biological functions of pesticides combinations. In this study, contact toxicity of Mentha piperita L. essential oil compared with its nano-emulsion on Tribolium castaneum herbs as well as its effect on wheat grain storage has been investigated. The results indicated that, production of nano-emulsion with this new technique results in considerable decrease of the required EO concentrations. The results concluded that by using nanoemulsion formulation, the effect of essential oil contact toxicity and its durability increases. Hence, the nanoemulsion formulation may represent a new category of biopesticide and this should be considered in the integrated pest management program.
