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.

    BIOECOLOGY AND INFESTATION BEHAVIOUR OF THE RICE MEAL MOTH, Corcyra cephalonica STAINTON (LEPIDOPTERA: PYRALIDAE) ON FOXTAIL MILLET, Setaria italica (L.)
    (University of Agricultural Sciences GKVK, Banglore, 2007-10-05) NIRMALA, P.; P. S. JAGADISH
    The incubation period of C. cephalonica on Foxtail millet at 25 ± and 71 ± 1.2 per cent relative humidity varied from 4 to 7 days (mean 4.66 days). Freshly hatched larva was creamy white coloured and passed through six instars. The average duration of each larval instar was 4.13, 5.04, 3,73, 3.40, 5.46 and 9.69 days, respectively and total larval duration took 31.26 days and pupal duration was 15.06 days. Developmental period took 41 to 59 days (average 51.95 days). Full grown last instar larva measured 11.02 mm in length. The mating period ranged from 60 to 130 minutes. The preovipositional period ranged from 1 to 2 days. Eggs were laid singly or in groups of 3 to 5 eggs in rare cases. Fecundity ranged from 90 to 150 eggs; oviposition period lasted for 6 to 8 days. Adult females, irrespective of food availabihty, lived longer than the males. The nature of larval development did not differ on Foxtail millet. The larva started forming grain cluster and started feeding inside the grain cluster. Finally each larva makes 3 to 4 such grain cluster and mixed with broken grains excreta and frass. The population stress study showed that a high release of initial moth pairs (12 pairs) resulted in the early operation of crowding effect and marked reduction in the population in subsequent generations. In the studies on the influence of different grain properties on C. cephalonica infestation, the broken grains and flour of Foxtail millet were most preferred for growth and development. Among the different varieties tested, Prasad variety offered maximum resistance to C. cephalonica infestation, which was reflected in terms of lesser adult emergence from this variety. Among varying grain moisture contents tested, 15.53 % was most favourable for pest which reflected in terms of higher survival and shorter developmental period. In host preference study, maize was the most preferred host which showed higher moth emergence and weight loss due to infestation.
