Impact of climate change on insect pests and their natural enemies

Sudhanshu Bala Nayak, Kavadana Sankara Rao, V Ramalakshmi

Climate change along with rapidly increasing population, depletion of natural habitats and resources would have direct impact on livelihoods and raising concerns for food security, water supply, health and energy. Climate change, an emerging global concern have serious threats in every aspects of agriculture. Changed patterns in climatic factors like temperature, precipitation, humidity and other meteorological components are affecting the quality and quantity of agricultural commodities production. Along with direct impacts in crop productivity, climate change is threatening global food production via pest related losses of food crops. Being poikilothermic, insects are the organisms that most likely to respond to changes in climate, and It is anticipated that the damage to agricultural crops by insects will increase as a consequence of climate change. It has increased pest population and their damage potential by expanding distribution, enhancing survivability and allowing to develop the adaptability of insect pest. Rising temperature, modified precipitation patterns, disturbed gaseous composition of atmosphere etc. are causing the change in population, mobility, behaviour of insect pest.
