About the Department

Department of Agricultural Entomology was established at Agricultural College and Research Institute, Madurai in August 1965. Subsequently M.Sc. programme in Agricultural Entomology was started in September 1969 and Ph.D. in November 1989. Since its inception, the Department of Agricultural Entomology is catering to the needs of the farmers through intensive research on pest management methods of different crops and advisory services to the extension functionaries of the Department of Agriculture and Horticulture. Advisory service on pest management is also made to non government and private organizations.
