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.

    STUDIES ON INSECT PEST COMPLEX OF WATERMELON Citrullus lanatus (Thunb.) AND THEIR MANAGEMENT
    (University of Agricultural Sciences, Bangalore, 19-08-08) HARISH VARMA, M; SRINIVAS REDDY, K M
    The present investigation on insect pests of watermelon, Citrullus lanatus (T.) and their management carried out under field conditions revealed that the major insect pests observed during cropping period were leaf miner, Liriomyza trifolii (Burgess); thrips, Thrips palmi (Karny); whitefly, Bemisia tabaci (Gennadius) and fruit fly, Zeugodacus cucurbitae (Coquillett) with mean populations of 3.89±1.88, 9.71±6.25, 3.67±2.77 and 4.91±5.92 respectively. These insect pests prevailed throughout the cropping period, while, red pumpkin beetle, Raphidopalpa foveicollis (Lucas) and leaf eating caterpillar, Diaphania indica (Saunders) were recorded as minor defoliators with mean populations of 0.29±0.34 and 0.27±0.31, respectively. Management of major insect pests with insecticides showed that cyantraniliprole 10.26 % OD was found to be superior over other insecticides against L. trifolii and B. cucurbitae with 79.78 and 48.68 per cent reduction over control respectively. Thiamethoxam 25 % WG was effective against B. tabaci with 87.07 per cent reduction over control. While, two sprays of fipronil 5 % SC was most effective against T. palmi with 76.18 and 76.89 per cent reduction over control during first and second sprays, respectively. Influence of usage of insecticides on natural enemies (spiders, coccinellids) and pollinators (Honey bees) were recorded. The results revealed that Spinosad 45 % SC was the safest insecticide to natural enemies and pollinators compared to all the other insecticidal treatments. Crop sprayed with cyantraniliprole 10.26 % OD recorded highest fruit yield among different insecticidal treatments with 51.83 t/ha. Whereas, the highest B:C ratio was found in fipronil 5 % SC with 3.39.

    EFFECT OF Metarhizium anisopliae (Metsch.) Sor. ON Tetranychus neocaledonicus Andre AND ITS PREDATOR Amblyseius ovalis Evans ON OKRA
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 1999-08-30) . HANCHINAL, SHIVANAND G; Manjunatha, Dr.M.
    Investigation on the efficacy of Metarhizium anisopliae on eggs, active immature and adults of spidermite Tetranychus neocaledonlcus a serious pest on okra and its predator Amblysleus ovalis were carriedout. The LC 50 for active form of mites was 1.9x10 3 spores/ml. Highest mortality is 92,82 per cent for adult, 72.93 per cent for immature and 87.82 per cent for the eggs in 1.8x10® spores/ml under laboratory conditions. Among the eight treatments evaluated against T,neocaledonlcus in the green house, 3x10® spores/ml + dicafol (0.03%) registered greater mortality. Conbsiderable mortality was also observed in predator A.ovalis under green house conditions. Among the eight treatments of fungi+dicofol evaluated under field conditions, highest mortality was 88.35 per cent in 1.5 x 10 14 spores/ha + dicofol (0.03%). Reduction in the mite population was related to incidence of fungus at seven and 15 days after spray application. Dosage level of 1.5 x 10 14 spores/ha + dicofol (0.03%) and 1.5x1014 spores/ha + dicofol (0.015%) exerted significant mortality on mite population. Considering the B:C ratio evolved due to use of fungus + dicofol the highest ratio is (50.45:1) in 1,5 x 10 14 + 0,015 followed by 1.5 x 10 14 + 0.03
