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.

    INSECT POLLINATORS OF SELECTED MEDICINAL CROPS WITH SPECIAL REFERENCE TO THE ROLE OF HONEYBEES IN POLLINATION OF HONEY PLANT, Ammi majus L.
    (University of Agricultural Sciences GKVK, Bangalore, 2008-06-10) SOWMYA, K. S.; KUBERAPPA, G. C.
    Insect pollinators activity was observed on seven selected medicinal crops viz., malbar nut tree (adusoge), garden rue (naagadaali), bitter wort (kaadu sevanthi), shyamakranta (vishnukanthi), stevia (madhuvantha), wild croton (kaadu haralu) and honey plant (madhu gida) during 2007 at Herbal garden, Division o f Horticulture, University of Agricultural Sciences, GKVK, Bangalore. At flowering, medicinal crops were visited by twenty five species of insects belonging to seven families of hymenoptera, two families of diptera and five families of lepidoptera. Foraging activity of honey bee species varied with the crop and time. The peak pollen and nectar foraging activity was observed between 1000 to 1400 h on all selected medicinal crops. Pollen load carried by different species of honey bees from honey plant, showed the significant variation. The maximum pollen load was carried by Apis cerena (5.15 mg), followed by A. florae (4.13 mg) and Trigona iridipennis (1.85 mg). The per cent seed set, per cent flower drop, seed length (cm) and 1000 seed weight were maximum in twelve bee visits per umbel. Impact o f different modes of pollination on qualitative and quantitative parameters in honey plant such as per cent flower drop, 100 fresh umbel weight, 100 dry umbel weight, number o f seeds per umbel, filled seeds, test weight, per cent oil content and germination were recorded significantly maximum in open pollinated plots, followed by plots caged with A. florea, A. cerena and T. iridipennis and lowest was recorded in control plots.

    STUDIES ON BEE FAUNAL DIVERSITY OF BANGALORE REGION
    (University of Agricultural Sciences GKVK, Bangalore, 2006-09-10) SUMA, S.; BHAT, N. S.
    The study on faunal diversity o f non-Apis bees (Super family: Apoidea) in and around Bangalore region revealed 37 species in 12 genera under three families viz, Apidae, Halictidae and Megachilidae and five sub families viz, Apinae, Xylocopinae, Halictinae, Nomiinae and Megachilinae. The genera included under the study are Amegilla Friese includes four species, Braunsapis Michener one species, Ceratina Latreille five species, Coelioxys Latreille one species, Halictus Latreille three species, Lasioglossum Curtis four species, Lithnrgus Berthold one species, Megachile Latreille seven species, Nomia Latreille four species, Thyreus Jurine two species, Steganomus Retsima one species and Xylocopa Latreille four species. All these species were collected while foraging on 24 different plant species. Each of the specimens are described and illustrated. Keys are also given for their identification. All these species are useful to mankind as pollinators. Megachile Latreille pollinates leguminous crops like field bean, french bean, red gram, sesame, crotalaria, and also tulasi. Xylocopa Latreille pollinates gliricidia, tomato, Brinjal, french bean, field bean, crotalaria, red gram. Ceratina Latreille pollinates tulasi, field bean, french bean, marigold, goldenrod, melissa, portulaca, crotalaria, sesame, Tecoma. These bees built their nests in tree hollows, building holes, soil mounds, wood burrows, bird nests etc. Megachile, mason bees were found building their nests in hard wood cuttings, building holes, egg shell sheat, by using mud, and leaf cutter bees were found building their nests in building holes using leaf bits. Amegilla confusa Smith also builts its nest in building holes using leaf bits. Ceratina (Pithitis) binghami Cockerell builts its nest in both soft and hard wood cuttings like rose and bamboo respectively. Ceratina (Pithitis) hieroglyphica Smith builts its nest in soft wood cuttings like rose. Xylocopa spp. built their nests in hard wood cuttings like eucalyptus and bamboo.

    STUDIES ON NON-APIS BEE FAUNAL DIVERSITY OF WESTERN GHAT REGION OF KARNATAKA
    (University of Agricultural Sciences GKVK, Bangalore, 2008-07-02) NAYANA, E. D.; BHAT, N. S.
    The study on faunal diversity o f Non- Apis bees (Super family: Apoidea) in and around western gnat region from places like Shimoga, Chikkamagalur, and Kodagu Districts revealed 47 species in 13 genera under 4 families viz., Apidae, Halictidae, Meghachilidae, and Collitidae and 6 sub-families viz., Apinae, Xylocopinae, Halictinae, Nominae, Meghachilinae, and Hylaeinae. The genera included under the study are Braunsapis Michener, Heriades Spinola and Anthidellum Cockerell one species each, Thyreus Jurine and Halictus Latreille two species each, Amegilla Friese, Ceratina Latreille and Meghachile Latreille. five species each, Lassioglosum Curtis and Nomia Latreille 4 species each, Coelioxys Latreille 3 species and Xylocopa Latreille 10 species. All these species were collected while foraging on 22 different plant species. Each o f the specimens are described and illustrated. Keys are also given for their identification. All these species are useful to mankind as pollinators. Amegilla Friese pollinates Thumbe, Adathoda, Balsam; Cerantina Latreille pollinates cucumber, ridge guard and bitter guard and Xylocopa Latreille pollinates beans, ridge guard, glyricidia and ankola. Meghachile Latreille pollinates datura, kuphia, lakki, techoma and pongamia. The bee diversity was higher at Shimoga dist followed by Chikkamagalore and Kodagu dists.

    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.
