Biography

Viraktamath was born in Byadagi to Adiveyya and Neelambika and grew up across Karnataka as his father was posted at various places as a revenue officer. He went to the College of Agriculture, Dharwad and obtained a BSc in agriculture winning an ASPEE Gold Medal in plant pathology. He joined the University of Agricultural Sciences, Bangalore for his MSc and received training from the Indian entomologist G. P. Channabasavanna as well as the American entomologists H. M. Harris and J. H. Lilly who were visiting professors in insect systematics and physiology respectively. He was involved in studying ragi (Eleusine coracana) mosaic and streak diseases which were spread by leafhopper vectors and was recommended for further studies at the Oregon State University as a Ford Foundation scholar. He went to work on leafhopper systematics under Paul W. Oman, working on the Old World Agallinae. He returned to India after receiving his PhD and worked at the College of Agriculture, Dharwad. After a few years of teaching he moved in 1974 to the University of Agricultural Sciences, Bangalore. From 1995 he taught graduate students. He was involved in the development of the synoptic insect collections at the university which under his curatorship grew to 350,000 specimens with the oldest being a weevil collected by Leslie C. Coleman in October 1908. All the type specimens of species that he described (56 genera and 452 species) are included in the collection. He mentored numerous students in systematics particularly of insects of agricultural importance. He retired in 2004 but continued to work as an emeritus professor. A festschrift in his honour was released on his 75th birthday. A number of insects have been named in his honour.[1]

He married Lalitha (née Shashikala Koranmath) in 1973 and they have two daughters.
