By the year 2020 approximately, the world is expected to have a population of 7-8 billion people. The proper feeding of these people will be a major challenge, especially for the farmers in Asia, Africa and Latin America who will have to provide food for the surplus populations on these continents. This can be achieved through three major programmes i.e. (i) organization of food production and distribution (ii) increased production, and (iii) a reduction in losses. In Asia, it will require a sustained increase in yield and better organization, as most arable land is already in production and expansion of the cultivated area cannot be expected. Dramatic increases in crops yield were noticed during the "Green Revolution" in the early seventies, when high-yielding cereal varieties were introduced into Asia. The book will be useful to all those who are preparing for competitive examinations conducted by various Central and State Government Agencies for recruitment. Every attempt has been made to provide necessary information related to Agricultural Entomology, which is not available in other books.
