Will climate change pose serious threat to crop pest management: A critical review?

Abiotically stressful environment in changing climate is predicted to impact negatively the diversity and abundance of insect-pests; and ultimately the extent of damage caused in economically important agricultural crops. This may affect perilously the agricultural production and the livelihood of farmers especially in tropical and subtropical countries where larger proportion of work force is directly depending on climate sensitive sectors such as agriculture. In this article, we enlighten through the extensive literature survey, the climate change induced challenges that the crop growers have to face in near future in managing harmful insect pests of their crops along with its socio-economic impacts on farming community. We feel it is timely and important that further studies pertaining to climate change driven changes in serious insect-pests of crops and planning and development of adaptive strategies needs to be undertaken to lessen the yield losses and safeguard the food security of nation.
