DYNAMICS OF INSECT-PLANT RELATIONSHIPS AND ITS APPLICATIONS IN CROP PRODUCTION
Journal Title: International Journal of Agriculture Sciences - Year 2017, Vol 9, Issue 6
Abstract
Plants and insects have coexisted for at least four hundred million years, and have evolved a variety of antagonistic and mutualistic relationships. As plants are attached by insect herbivores, they have evolved different defense mechanisms to reduce insect attack. Constitutive defenses are present continuously in the plant, but the induced defenses are activated only after the insect attack. The activation of induced defenses is result of highly sophisticated signaling system. In course of time, insect have also evolved several mechanisms to overcome plant defense barriers. In pollination, insects pollinate the plant in exchange of nectar and pollen, thus both are mutually benefitted. In addition, various carnivorous plants are known that have developed mechanisms to trap and digest insects in order to supplement their food requirement. Thorough knowledge of insect plant relationship can be exploited for sustainable crop production.
