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.

    INTEGRATED MANAGEMENT OF FIGEONPEA POD BORER, Helicoverpa armigera (Hubner) WITH SPECIAL REFERENCE TO //aNPV AND INSECTIVOROUS BIRDS
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 1999-08-30) GOPALI, JNANESHWAR B.; Lingappa, Dr. S.
    Studies were conducted from 1994 to 1996 at the Agricultural Research Station, Gulbarga and Main Research Station, UAS, Dharwad. Female to male moths in 10:13 ratio in a oviposition cage increased fecundity (504 eggs) and hatchabUity of eggs (64.2%) after incubating them in earthen pot covered with cloth and kept in moist sand in plastic basin. Rearing of neonate larvae on chickpea seedlings up to four days in group, and thereafter individually on artificial diet afforded highest survivability . Fourth instar larva was found ideal for large scale production of virus (2.81 x 10® POB larva). Plant shaking method was found to be most productive to collect the larvae in pigeonpea ecosystem. Cost of production of 100 LE from laboratory reared larvae was Rs. 102j0, being Rs. 25.40 more than from field collected larvae (Rs. 76.80). HaNPV stored under refrigerated conditions maintained virulence throughout the year as against four and six months, respectively, under ambient and earthen pot conditions. Combined use of both UV protectant (Robinblue 0.05%) and phagostimulant (0.5% of soymilk, or cotton seed kernel extract or jaggery ) not only resulted in higher and quicker mortality, but also increased the persistence of HoNPV. HaNPV @ 500 LE ha-1 twice at 15 days interval starting from flowering stage gave satisfactory control H. armigera. Application of HaNPV with high volume sprayers (Knapsack, battery operated and foot sprayers) was more effective compared to ULV sprayers. Among insectivorous birds, black drongo, house sparrow, green oee eater and blue jay accounted for 60.3, 19.8, 12.9 and 6.8 per cent of larval predation, respectively. Field evaluation of different perches revealed that animate perch (sorghum variety with bow head) @ 2500 ha-1 (300- 400 grams of seeds ha-1 was found most efficient in reducing the larval number and increasing the grain yield over other t5q3es of perches evaluated. Predatory actrity was hampered in synthetic insecticide sprayed plots. Bird droppings contained virulent virus particles (7 x 10® POB/ml). Evaluation of different IPM schedules with sorghum as bird perch module comprising of HaNW (500 LE ha-1), NSKE (5%) + HaNFY (250 LE ha-1), chlorpyriphos (0.04%), alphamethrin (0.01%) and module involving two sprays of HaNPV (500 LE ha fi, and one each of chlorpyriphos and alphamethrin (0.01%) were not only cost competitive, bui also were socially acceptable, ecologically balanced and easily adoptable.

    STUDIES ON Chrysoperla camea (Stephens) AND ITS EVALUATION UNDER COTTON ECOSYSTEM

The mass rearing of 100 larvae per basin of size 35 cm diameter and 7 cm height was found to be nptiaw.

The response of C.camea third instar larvae starved for four hours was maximum (1.22 min) when exposed to wax droplets coated with H.anaigera scale extract. Among the food attractanu tried, tryptopfaan (0.01%) proteincx (2%) mixture concentration was found to be promiring in attractioa of Ccanea adults on cotton ctop.
