University of Agricultural Sciences, Bengaluru

University of Agricultural Sciences Bangalore, a premier institution of agricultural education and research in the country, began as a small agricultural research farm in 1899 on 30 acres of land donated by Her Excellency Maharani Kempa Nanjammanni Vani Vilasa Sannidhiyavaru, the Regent of Mysore and appointed Dr. Lehmann, German Scientist to initiate research on soil crop response with a Laboratory in the Directorate of Agriculture. Later under the initiative of the Dewan of Mysore Sir M. Vishweshwaraiah, the Mysore Agriculture Residential School was established in 1913 at Hebbal which offered Licentiate in Agriculture and later offered a diploma programme in agriculture during 1920. The School was upgraded to Agriculture Collegein 1946 which offered four year degree programs in Agriculture. The Government of Mysore headed by Sri. S. Nijalingappa, the then Chief Minister, established the University of Agricultural Sciences on the pattern of Land Grant College system of USA and the University of Agricultural Sciences Act No. 22 was passed in Legislative Assembly in 1963. Dr. Zakir Hussain, the Vice President of India inaugurated the University on 21st August 1964.

    RISK ANALYSIS OF BIO-PESTICIDES AND NEWER MOLECULES ON HONEY BEE POLLINATORS IN SUNFLOWER ECOSYSTEM
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2018-11-20) SHABARISH KUMAR, S.; SRINIVAS REDDY, K. M.
    Studies on effect of bio-pesticides and newer molecules on honeybee pollinators in sunflower ecosystem were carried out at Department of Apiculture and Zonal Agricultural Research Station, GKVK, Bengaluru during 2017-18. Insecticides viz., Bacillus thuringiensis, NPV, NSKE, Indoxacarb, Cyantraniliprole, Chlorantraniliprole, Spinosad and Emamectin benzoate were sprayed during flowering period on sunflower crop. The foraging activity of different honey bee species was observed for 7 days. Emamectin benzoate was found to be more toxic to honey bee pollinators followed by spinosad, cyantraniliprole, indoxacarb, NSKE, chlorantraniliprole, Bacillus thuringiensis and NPV. Emamectin benzoate was found to be highly toxic to A. dorsata and A. cerana followed by spinosad, cyantraniliprole, indoxacarb, NSKE, chlorantraniliprole, Bacillus thuringiensis and NPV under field condition. NPV was found to be relatively safer to A. florea followed by Bacillus thuringiensis, chlorantraniliprole, NSKE, spinosad, indoxacarb, cyantraniliprole and Emamectin benzoate, whereas NPV was found to be least toxic followed by Bacillus thuringiensis, chlorantraniliprole, indoxacarb, spinosad, NSKE, cyantraniliprole and emamectin benzoate to Tetragonula irridipennis under field conditions. In laboratory conditions NSKE was found to be least toxic to A. cerana whereas Emamectin benzoate was found to be highly toxic.
