Global climate change caused by increased giving out of greenhouse gases affect the agro-ecosystems in many ways, outcome of which depend on the combined effects of environmental temperature, precipitation and other global changing factors. Insects respond to climate change by different ways i.e., changes in an insect population’s physiology, biochemistry, biogeography and population dynamics. An insect population’s response to a rapidly changing climate may also be erratic when insects interact with different competitors, predators and parasitoids. Due to the climate change, there is a raise in the number of insect pest population, out breaks of insect, increased number of generations and development of resistant biotypes. Climate changes cause negative impact on the natural enemies’ population. This also can manipulate the overall food production system that can be at critical risk from the impacts of climate change.
