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 BEHAVIOUR OF DIAMONDBACK MOTH, Plutella xylostella (L.) (PLUTELLIDAE: LEPIDOPTERA) TO SEX PHEROMONES IN CABBAGE ECOSYSTEM
    (University of Agricultural Sciences, Bangalore, 2023-04-11) ABHISHEK D. KATTEPPANAVAR; MOHAN I. NAIK
    Studies on evaluation of commercial sex pheromone lures (Green revolution pheromone lure, Gaiagen pheromone lure, Pheromones chemical lure, Bio Phero PX lure) against diamondback moth, Plutella xylostella in cabbage were carried out in the farmers field around Hadonahalli village, Bangalore. Among the lures tested, Gaiagen lure shown the significant moth catches (2,218 moths/season, average of 277.25 moths/week). Diamondback moth larval activity initiated a week after transplanting, with peak incidence of 4.6 larvae per plant at head formation stage. The study showed positive correlation between the moth catches of the present week with the larval incidence occurred two weeks later. The highest cost-benefit ratio was recorded in Gaiagen lure (3.17). Followed by Among the five different commercial traps evaluated (Water trap, Delta trap, Funnel trap, Cross vane trap, Wing vane trap), the water trap recorded the highest number of moth catches of 1052 moths per season with an average of 131.5 moths/week, with a Cost Benefit ratio of (3.07). The standardisation of trap timing experiment revealed that, treatment on the day of transplanting recorded 1913 moths per season with a least larval incidence of 1.42 larvae per plant. Treatment on the day after transplanting recorded 71 per cent grade ā€œAā€ cabbage heads with a yield of 28.55 t/ha and a highest Cost benefit ratio (7.33). On the 30th day after transplanting had a least effect on the yield (20.05 t/ha) of cabbage and also recorded highest percentage (24%) of grade ā€œCā€ heads.
