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.

    ROLE OF FLOWER VISITORS IN BITTER GOURD (Momordica charantia L.) POLLINATION AND SEED PRODUCTION
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2016-10-16) THARINI, K. B.; KHADER KHAN, H.
    Bitter gourd (Momordica charantia L.) is one of the most popular, annual tropical vegetable crops probably originated in South East Asia. It is widely grown in India, Indonesia, Malaysia, China and tropical Africa. It is a monoecious climbing type herbaceous crop belonging to the family Cucurbitaceae, which consists of 130 genera and 900 species. Depending on the location, it is known by different names- balsam pear, bitter melon, bitter cucumber and African cucumber (Heiser, 1979).

    Effect of elevated carbon dioxide, temperature, plant secondary metabolites on biology and molecular diversity of melon fruit fly Bactrocera cucurbitae Coquillett (Diptera: Tephritidae)

    Climate change may lead to expansion or intensification of damage to cucurbit groups by melon fruit fly. Global warming may also impact management practices which are currently being practiced against melon fruit fly in cultivated ecosystems. Therefore, biological studies under elevated temperature and CO2 levels were carried out in the laboratory. As the temperature increased beyond 240C the mortality of melon fruit fly increased from 19.07 % at 240C to 100 % at 360C. Melon fruit fly exhibited almost normal growth and development at 240C. Levels of elevated carbon dioxide (380 and 570 ppm) did not elicit varied response to melon fruit fly growth and development. In a given cucurbit vegetables and varieties, levels of phenols, tannins, sugars and proteins significantly influenced in rendering the resistance or susceptible. Phenols and tannins assist the cucurbit fruits in defending against the attack of melon fruit fly while sugars and proteins make it vulnerable for the cucurbits to fruit fly damage. Estimates on activity of antioxidant enzymes viz., POD, SOD, PAL and CAT revealed that high activity in chow chow and bottle gourd did not support the growth and development of melon fruit fly. For instance, in chow chow, the peroxidase activity increased two folds from healthy (6.14 μmoles min-1mg protein) to affected fruits (11.33 μmoles min-1mg protein) and exhibited increased peroxidase activity of 252% more activity compared to snake gourd with only 84.13% increase. The SOD showed increased activity of 39.16% from healthy to apparently healthy fruits compared to only 10.52% increase in snake gourd which is highly susceptible. Similarly, increased PAL activity of 389% more in apparently healthy fruits compared with healthy fruits and only 17.61% increase was observed in snake gourd. In contrary to the above enzymes, the maximum decrease in catalase activity was observed in chow chow i.e. 56.62% compared to snake gourd which showed increased activity of 7.75%. Molecular diversity of melon fruit fly populations are genetically heterogenous across different climatic zones of Karnataka. This indicted that, further studies involving ITS markers are essential for detecting differences among genetically different populations. Such studies are essential as they provide crucial information for developing management practices in different agroclimatic zones.

    INVESTIGATIONS ON INSECTICIDE RESISTANCE IN Spodoptera litura Fab. (LEPIDOPTERA: NOCTUIDAE)
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2007-02) KITTURMATH, M S; SANNAVEERAPPANAVAR, V T
    The tobacco caterpillar, Spodoptera litura (Fabricius), which was known earlier to be a sporadic pest, has emerged as destructive polyphagous pest in the recent past. This pest is distributed throughout southern and eastern world viz., tropical and temperate Asia, Australia and Pacific Islands (Feakin, 1973 and Kranz et al., 1977) and infests more than 112 crop species belonging to 44 families, of which 40 species are known from India. The major host plants of S. litura include tobacco, cotton, groundnut, castor, chilli, potato, soybean, cauliflower, cabbage, tomato, beans and sunflower etc. The damage is done by the larvae, which initially scrape the leaf tissue gregariously and feed in clusters and quickly skeletonize the leaves. The grown up larvae defoliate the plants completely. This pest is next only to Helicoverpa armigera (Hub.) in economic importance both at national and global level. Recently, the pest has been appearing in severe form, especially during rainy and post rainy seasons causing heavy yield losses throughout India. In 2003, its outbreak occurred in Pakistan throughout the cotton belt devastating the crop (Mushtaq Ahmad et al., 2007). The S. litura accounts for up to 17.71 and 70.00 per cent yield losses in groundnut (Anon., 1983) and black gram (Krishnaiah et al., 1983) in Karnataka and Andhra Pradesh, respectively. The monetary value of annual yield losses due to major insect pests including S. litura in all the important agricultural crops is estimated to be Rs. 29,240 crores (Dhaliwal and Arora, 1996).
