Govind Ballabh Pant University of Agriculture and Technology, Pantnagar

After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960. The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

    Studies on host preference, olfactory and functional response of generalist predator, Eocanthecona furcellata (Wolff.)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2020-10) Chaudhary, Devyani; Maurya, R.P.
    The present investigations were carried out at Biocontrol Laboratory, Department of Entomology, Govind Ballabh Pant University of Agriculture and Technology, Pantnagar during 2018-2020. Results on host preference of 2nd nymphal instar, 3rd nymphal instar, 4th nymphal instar, 5th nymphal instar and adult predatory bug of Eocanthecona furcellata revealed that Spodoptera litura followed by Corcyra cephalonica and Spilarctia obliqua were found as preferred host. The percent preference of second, third, fourth, fifth nymphal instars and adult predatory bug were 41.67, 50.00, 58.33, 75.00, 83.00 percent on S. litura, respectively. Results of the host selection by olfactory response revealed that the adult predatory bug preferred odour cell with larval extract of S. litura (48%), followed by larval extract of S. obliqua (32%), C. cephalonica (14%) and control odour cell (8%). The predatory bug was able to complete its immature life in five nymphal instars on live and freeze killed larvae of S. litura and C. cephalonica. The total nymphal period varied from 17.33±0.88 to 21.33±0.33 days. Total life cycle ranged from 31.33±0.33 to 36.33±0.66 days and number of eggs laid varied from 25.33±0.88 to 67±1.15. The consumption rate of nymphal instars ranged from 34.16±1.27 to 51±4.93 percent, 45.83±3 to 68.89±1.11 percent, 59.04±0.95 to 71.33±5.81 percent, 55.83 ± 4.40 to 81.11±1.82 percent. The consumption rate of adult predatory bug on different factitious hosts varied from 75.8±0.54 to 84.79±1.18 percent. The mean consumption rate of different stages of predatory bug ranged from 45.86±0.52 to 59.27±1.98 percent on live and freeze killed larvae of S. litura and C. cephalonica. The results of the study of functional response of fourth, fifth nymphal instars and male and female predatory bug on four, six, twelve days old larvae of S. litura demonstrated a type II functional response at different prey densities. The estimated parameters of attack rate of fourth, fifth nymphal instars ranged from 0.942±0.04 to 1.506±0.199, 0.969±0.017 to 1.161±0.074 prey/ day with a handling time of 0.075±0.017 to 0.58±0.087, 0.027±0.007 to 0.443±0.066 days at different prey densities. The parameters of attack rate estimated for male predatory bug on four, six, twelve days old larvae of S. litura were 0.975±0.014, 0.901±0.033, 0.844±0.092 whereas, for female predatory bug, attack rate was estimated as 0.982±0.015, 0.927±0.033, 0.903±0.032 prey / day, respectively. The handling time of male and female predatory bug varied from 0.024±0.006 to 0.204±0.04 and 0.013±0.007 to 0.099±0.014 days, repectively. The study suggested that the predatory bug, E. furcellata can be mass reared in laboratory conditions using larvae of S. litura and C. cephalonica and could be exploited in various IPM programmes.
