Using some Plant Essential Oils as natural fumigants against adults of Callosobruchus maculatus (F.) (Coleoptera: Bruchidae)
Abstract :Present study was aimed to investigate fumigant toxicity of essential oils extracted from Lippia citrodora Kunth., Rosmarinus officinalis L., Mentha piperita L. and Juniperus sabina L. against adults of cowpea weevil, Callosobruchus maculatus (Col.: Bruchidae). Essential oils were extracted from aerial parts of plants via hydrodistillation. Adults (1-7 days old) of insects were exposed to a series of concentrations of essential oils for 24 h and then the numbers of dead and alive insects were counted. Results showed that essential oil of M. piperita (LC50 7.86 µl/L air) was significantly more toxic than L. citrodora (LC50 187.51 µl/L air), J. Sabina (LC50 134.35 µl/L air) and R. officinalis (LC50 46.81 µl/L air). Results of this investigation suggested that essential oils of these plants could be used as safe fumigants for controlling of C. maculatus in small scales
