Silicon (Si) played a major role in plant growth, mechanical strength and resistance to biotic and abiotic stresses. It has been recently identified that, Si relating to plant physiology, plant chemistry and gene regulation mechanism. Silicon has received great attention as a nutrient capable of providing some measure of defense for plants against insectpests, fungal pathogens and herbivores. The beneficial effects of Si are usually expressed more clearly in Si-accumulating plants under various abiotic and biotic stress conditions. On the basis of a study including two generalist insectfolivores and a phloem feeder have drawn attention to a putative distinction between the effects of plant Si in defending against folivoresand phloem-feeding insects. Plant resistance to herbivores is a crucial component in integrated pest management. Silicon application to plants enhances resistance mechanism which is observed in most of the cases to herbivorous insects.
