Agriculture is the lynchpin of the Indian economy. At present, the country holds the second position all over the world in terms of agricultural production. Agriculture in India is a major economic sector and it creates plenty of employment opportunities. Ensuring food security for 1.35bn Indian population with diminishing cultivable land resource is a herculean task. The word pest comes from the Latin word “pestis” which includes an animal or plant that occurs in such abundance as to present a distinct threat, economically or medically to man or his interest. A pest may be insect, fungus, weed, rodent, bacteria, virus, nematodes, acarid / mite, parasite and even animal or bird. Pests are organisms that diminish the value of resources in which we are interested.
