ABSTRACT
Climate change encompasses myriad of climatic conditions that will have a long term effect on arthropod diversity, herbivore plant interactions, geographical distribution of insect pests, ecological balance related to natural enemies, pesticide efficacy for the management of insect pests and so on and so forth. Anthropogenic activity that is responsible for climate change includes greenhouse gas emission that would likely have a significant effect on the range expansion, life history, population dynamics and tritrophic interactions of insects, as they are poikilothermic in nature. Climate change can also tremendously influence plant defense and resistance to insect pests, performance of pesticides, invasive insect species etc. Increased insect pest load on crop plants, outbreaks, and more number of generations per year as a result of climate change will limit crop yield and increase cost of plant protection if the climate change issue is not addressed. It will have an overall effect on the global food production, environmental costs, ecological imbalance and affect the economies of the countries that are dependent on agriculture.
