Toxicological Stability of <i>Ocimum basilicum</i> Essential Oil and Its Major Components in the Control of <i>Sitophilus zeamais</i>

Essential oils (EOs) are widely recognized as efficient and safe alternatives for controlling pest insects in foods. However, there is a lack of studies evaluating the toxicological stability of botanical insecticides in stored grains in order to establish criteria of use and ensure your efficiency....
