Current statistics suggest that an alarming rate of depleting fertile land and water resources are making the issue of food security more severe. Preharvest and post-harvest losses due to biotic and abiotic factors take a huge toll on food production. As per an estimate, 12-16 million metric tons of food grains, which would have been sufficient enough to feed the significant numbers, is lost every year. In order to complete its life cycle and produce food, plant faces attack from various pests. Some of these pests are life threatening while others are like life-sucking that greatly hamper the growth and development of the plant, which results in poor growth and ultimately reduced yield. In addition to abiotic factors, biotic factors such as important plant pests, plant diseases, insects, rodents and nematodes are major contributors to this loss. The damage caused by the visible biotic factors is possible to estimate but in case of unseen biotic factors, whose impact on food production, particularly the losses, is mostly overlooked. The aim of this short communication was to present the impact of important biotic factors such as plant-parasitic nematodes and insect pests on the food security through the losses they cause to various important crop plants in India. We have, for this study, looked into various references, published research articles and supplementary information about the current topic of study, analyzed and summarized the findings. Through this, we attempt to analyze the impact of two of the important enemies of food security in India.
