Teodoro et al. (2010) for the first time studied the insecticidal activity of nanostructured alumina against two insect pests viz. S. oryzae L. and Rhyzopertha dominica (F.), which are major insect pests in stored food supplies throughout the world. They reported significant mortality after 3 days of continuous exposure to nanostructured alumina-treated wheat Therefore, as compared to commercially available insecticides,inorganic nanostructured alumina may provide a cheap and reliable alternative for control of insect pests, and such studies may expand the frontiers for nanoparticle-based technologies in pest management.
