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 SOME BEHAVIOURAL ASPECTS OF LITTLE BEE, Apis florea Fab. (HYMENOPTERA: APIDAE)
    (University of Agricultural Sciences GKVK, Bangalore, 2007-08-10) SHWETHA, B. V.; Gavi, Gowda.
    The present investigations were carried out to study the pasturage sources, melissopalynology, palynology, foraging distance, swarming and its prevention, absconding and post absconding behaviour in A. florea. Foraging activity of A. florea in comparison with A. cerana during different weather conditions and Pollinator fauna and abundance of A. florea in some selected plant species were also studied. Total of 147 plant species belonging to 48 families were found to be foraged by A. florea. Melissopalynological studies revealed that Cuphea micrantha, Cocos nucifera, Psidium guajava, Eucalyptus sp., Foeniculum vulgare, Mangifera indica, Pongamia pinnata, Peltophorum ferrugineum, Tamarindus indica, Callistephus chinensis and Brazil plant were dominant in the A. florea honey samples analysed from GKVK, Bangalore. Palynological investigations made on pollen loads of A. florea foragers revealed that Guizotia abyssinica, Helianthus annus, Anacardium occidentale, Mangifera indica, Punica granatum, Foeniculum vulgare, Burscera delpechiana, Mentha spicata, Nepeta cataria, Ocimum kilimandscharium, Raphanus sativus, Cuphea micrantha, Antigonon leptopus, Callistemon lanceolus, Eucalyptus sp., Simaruba glauca, Pongamia pinnata and Tamarindus indica are the dominant pollen types in GKVK campus. Swarm preparation was observed from November to March. Absconding was observed during February to March. Punching of queen and drone cells delayed the swarming process by 11- 98 days. After the desertion, workers from the same colony were found to return and collect the wax from the honey portion and upper periphery of the comb. A. cerana and A. florea were more active during bright sunny days than cloudy days. However A. cerana recorded higher activity than A. florea during sunny as well as cloudy days. Among the insects species visited flowers of radish, niger, rose apple and simaruba, A. florea was dominant.
