Conservation Agriculture for the management of insect pests- A review

Shamik Dey, Krishna Karmakar

Declining in soil health condition through conventional agriculture system is a serious worldwide problem that not only decreases sustainability and stability of agricultural ecosystems but commonly making them more prone to outbreaks of different herbivorous insect pests in different field crops and vegetables production which are currently characterized by high soil disturbance and solely depend on use of synthetic fertilizers and insecticides. Adopting soil conservation techniques increases mortality and decreases reproductive output for the major insect pests of different field crops and vegetables. Well known mechanisms responsible for such effect include huge development of population density of many of natural enemies such as predators, parasitoids, enhancing plant defenses mechanism by producing secondary metabolites, and modified agricultural habitats by organic amendment. Still more research efforts should needed for better understanding and elucidating the interactions between conservation agriculture and insect pest population dynamics.
