Abstract
Crop pest includes insects, pathogens and weeds which are one of the most crucial factors that cause yield loss to a greater extent.The negative impact of climate change on agriculture must be discussed under the light of its effect on crop pests. Climate change indirectly affects the pest dynamics by altering their ecology. Population dynamics, life cycle, geographic range, physiology of the pests depends on temperature, rainfall, relative humidity, radiation, carbon-di-oxide concentration, soil moisture etc. The host-pest-environment relationship is influenced by the changes in weather, soil and crop factors which are subjected to alteration due to the climate change.
