Emerging Insect-Pests of Vegetables Due to Changing Climate

Abstract

Climate change, an emerging global worry to farming in many countries and it is the most discussed topic in many forums as it affects the many livelihoods including human beings. Many weather affecting the different forms of life including hexapods by impacting in hexapod fecundity, habit, habitat, behavior, endurance, mobility, generation’s asynchrony between plants and pests, altered inter-specific interaction, increased hexapod vectored diseases and reduce the effectiveness of natural enemies. The global warming is also threatening overall food production any country by way of shifting hosts, moving to higher elevation, minor pests becoming major pests and increased invasiveness due to trade of different agricultural commodities. Many of the insect-pests are affecting hosts plants including vegetables as most of the insect are polyphagous in nature, they easily shift from one crop to other crop irrespective of cereals, pulses, vegetables and fruit crops there by damaging host plant and in turn reducing the productivity. Before we deal with different management strategies there is wide concern to address the climate change effects on the hosts as well environment as whole.
