Effects of global warming on pest status in agriculture

Abstract

Global warming has been a great concern now a days. The harmful effects of global warming has both positive and negative effect on the pest population and it hampers the pest management strategies in agricultural field. For this reason, global warming has been an important criterion in Entomology. Having tolerance of narrow range of temperature, insects are greatly affected by the change in temperature. It affects the distribution and migration of pests across the field. Insects may experience additional or reduced life cycle due to change in weather conditions. Hence the basic biology, lifecycle and life span of insects are hampered by the change in climatic conditions.
