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.

    AUGMENTATION OF THE PREDATORY BUG Eocanthecona furcellata Wolff (HEMIPTERA: PENTATOMIDAE) FOR MANAGEMENT OF PEST COMPLEX OF BRINJAL AND TOMATO

    The integration of biocontrol strategies for management of lepidopteran pests of brinjal and tomato provide sustainable solution. Eocanthecona furcellata Wolff. is considered as one of the potential predators against lepidopteran pests. The peak population of E. furcellata was observed during winter than summer months. The predation rate of E. furcellata on lepidopteran pests of tomato and brinjal studied suggested that females required more prey than males in order to prepare for egg production. The finite predation rate (ɷ), intrinsic predation rate, net consumption rate (C0) and stable predation rate (Psi) of E. furcellata were significantly higher on earlier instars than on later instars of prey larvae provided. Studies on biology, reproductive and life table parameters of E. furcellata on various lepidopteran hosts showed that the mass rearing of E. furcellata was feasible on three hosts, Samia cynthia ricini, Corcyra cephalonica and Galleria mellonella due to the ease of their mass rearing, availability throughout year and low rearing costs. The characters like higher fecundity, high survival and feasibility of group rearing of E. furcellata are amenable features for mass rearing. Under field condition the per cent reduction over control of Leucinodes orbonalis and Helicoverpa armigera infestation by fifth instars of E. furcellata was up to 36.9 and 39.7 per cent, respectively. Five releases of E. furcellata at weekly interval were effective in reducing the incidence of L. orbonalis and H. armigera. Hence, these predatory bugs could be promoted for suitable biological control programs to regulate the lepidopteran pests of brinjal and tomato.
