Knowledge of plant-insect interaction is continuously evolving with the coevolution of both interacting partners. In addition, the dynamic environmental factors are playing crucially into the interface chemistry of both the host plant and the attacking herbivorous insect. The present study has made efforts to shed light on the current knowledge of insect behavior during herbivory. Behavioral pattern of insects feeding on various plant hosts revolves around modifying host surveillance and overwhelming their defense mechanisms. On the contrary, hosts pay full attention on strengthening its defense arsenal with adequate and appropriate armors that can mount a timely resistance against the attacking insect. In this context, the molecular role of most important class of phyto-biomolecules referred to as phytoanticipins, phytoalexins, and phenolics that were widely investigated as potential insecticides since early days are elaborated under the light of recent day understanding. Thus, the chapter schematizes the general understanding of plant-insect interaction with an aim at adding to the knowledge of the development of better insect management strategies in the near future.
