Elevated CO₂ and temperature resetting the expression of resistance, pest incidence, geographical distribution and physiology in insect-pests of grain legumes: A review

The most important factor that affects the crop production in terms of nutritional content of foliar plants is the global climate change. Herbivore's growth, development, survival and geographical distribution all are determined by elevated CO₂ and temperature. The interactions between herbivores and plants have changed due to increasing level of CO₂ and temperature. The effect of high CO₂ and temperature on grain legume plant which change in to plant physiology (e.g., nutritional content, foliage biomass) and how it change in herbivory metabolism rate and food consumption rate. Plant injury is determined by two factors viz. resistance and tolerance and both are influenced by greater CO₂ and temperature. Legumes are an important source of food and feed in the form of proteins and also improve the soil environment. The repercussions of the abiotic factors mentioned above needs discussion among the scientific community. We may able to limit the negative repercussions of stated factors in future breeding projects by harnessing the practical favourable impacts and by including such influences of elevated CO₂ and temperature on pulses productivity. The extensive research is necessary to overcome the negative effects of high CO₂ and temperature on insect-plant interaction.
