Repellent and Toxicant Effects of Eight Essential Oils against the Red Flour Beetle, Tribolium castaneum Herbst (Coleoptera: Tenebrionidae)

This study was conducted to compare the repellent effect and contact toxicity of eight essential oils (EOs), including , , , , , , and , against adults of Herbst. Four concentrations (1, 5, 10, and 15% in acetone solvent) of each EO were tested. The 5, 10, and 15% concentrations of EO had a high rep...

Description
Summary:This study was conducted to compare the repellent effect and contact toxicity of eight essential oils (EOs), including , , , , , , and , against adults of Herbst. Four concentrations (1, 5, 10, and 15% in acetone solvent) of each EO were tested. The 5, 10, and 15% concentrations of EO had a high repellency effect against compared with , , , , , , and after 30 min of exposure. The repellency test of the , , , , , and EOs on has shown that the mortality percentages enhanced with the increase in the EOs concentration and also with the exposure time. The 15% concentration of and EOs have a significant impact on the mortality rate of compared with , , , and after the 24 h of contact test. Moreover, the 15% concentration of the EO caused a greater mortality percentage compared with , , and . It could be concluded that using the EO as a repellent oil and using , and for contact toxicity to treat the flour infested by can play an important role in protecting stored grains and their products.
