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.

    Biological and phylogenetical studies of whiteflies from north-western Himalayan region
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-03) Patel, Chenesh; Srivastava, R.M.
    An integrated approach was carried out to explore the diversity of reproductive host plant, along with the seasonal incidence, host preference and biotic potential, taxonomic identification using molecular and morphological tools and use of essential oils for the management of whiteflies in Uttarakhand Himalayan region. Extensive surveys were conducted in 45 locations of 4 district of Uttarakhand during 2017-2019 to record the potential reproductive host associated with Bemisia tabaci and Trialeurodes vaporariorum and total 118 host plant species belonging to 49 families were documented. Host plants belonging to family Asteraceae, Fabaceae, Solanaceae, Cucurbitaceae, were found as most preferred host plant by both B. tabaci and T. vaporariorum. Whitefly (B. tabaci) was present on brinjal and tomato throughout the cropping season at Vegetable Research Centre, Pantnagar during 2017-2019 and its peak activity was observed on last week of December in both the crops. Whitefly population had significantly negative correlation with maximum temperature (r= -0.50** and r= -0.53**), minimum temperature (r= -0.61** and r= -0.57**) and evaporation (r= -0.64** and r= -0.66**) while non significant correlation was observed with sunshine hours in both the years on tomato and brinjal plants. The feeding and oviposition preference and biotic potential studies proved that among all brinjal was the most preferred host for feeding and oviposition followed by tomato and cabbage for B. tabaci and T. vaporariorum while the least preferred host recorded was bottle gourd and chilli for B. tabaci and T. vaporariorum respectively. Similarly, the preimaginal developmental period of immature stages of B. tabaci and T. vaporariorum was faster on brinjal (19.40 days and 21.57 days) than on tomato (22.40 days and 24.03 days). The survival rate was also maximum in brinjal plants for both the species as compared to tomato. The comparative morphological studies of life stages of B. tabaci and T. vaporariorum showed distinct differences in morphological features such as the no. of marginal setae, vasiform orifice, ligula, antennae and eyes. Morphological and morphometric features of both whitefly species were imaged and illustrated in detail for correct field level identification. The molecular diversity of B. tabaci and T. vaporariorum using mt COI markers followed by sequencing revealed the preponderance of genetic diversity in whitefly species. In case of B. tabaci, five different types of biotypes were found i.e., Asia II-1, Asia I, Asia II-5, MEAM 1 and Uganda. In case of T. vaporariorum the obtained phylogenetic tree revealed that there was no variation in the collected samples. Various plant essential oils were tested for repellency and ovipositional deterrent effect against B. tabaci. Among all the essential oils, mint oil showed maximum repellency and ovipositional deterrence, followed by tulsi and citronella oil while, significantly low repellency and ovipositional deterrent effect was recorded in lemongrass oil
