Herbivores are common and frequently severe restrictions on crop productivity. The use of insect-resistant crops for the management of insect pests in agriculture is an extremely efficient means, and understanding about plant resistance mechanisms and genes involved may significantly improve the creation of such crops. Plants have developed a variety of methods to deal with insect attacks which have led to natural variations in herbivorous insect resistance. The study of the molecular genetics and transcriptional backdrop of this polymorphism has made it easier to identify resistance genes and mechanisms leading to insect resistance. Molecular investigations are no longer limited to model plants with the advent of new technology. This review highlights the need to make use of the natural variations in insect resistance to enhance our understanding of resistance mechanisms and the genes involved. We will explain how this information may be used to offer sustained plant protection against insect pests in breeding projects. Furthermore, we address the present state of insect-resistance genetic research. We believe that the causes of insect resistance are still unknown at molecular level and that using new technology will help significantly to the creation of insect-resistant crop species.
