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.

    Efficacy of some insecticides against major insect pests of soybean and their impact on natural enemies (Spiders and Coccinellids)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2007-07) Panda, KshirodraKumar; Shri Ram
    The present investigation was carried out at CRC of Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, Distt. Udham Singh Nagar (Uttarakhand) to check the “Effectiveness of some chemicals as well as cow urine based insecticides against insect pests of soybean and their impact on coccinellids and spiders.” Soybean is an important legume providing 43 per cent protein and 20 per cent oil. It is attacked by 273 insect pests, hampering the crop production. Thus it is necessary to control them. Result showed that overall defoliator population (tobacco caterpillar, green semilooper, Bihar hairy caterpillar) was effectively checked by indoxacarb @ 150 ml/ha, chlorpyrifos @ 0.3% and Kamdhenukitnashi @ 1% and 2%. Bihar hairy caterpillar(Spilarctia obliqua) was effectively controlled by Kamdhenukitnashi @ 1% and 2%. While, larval population of Spodoptera litura was brought down by Kamdhenukitnashi @ 8% and indoxacarb @ 150 ml/ha. Similarly, indoxacarb @ 150 ml/ha and chlorpyrifos @ 0.3% provided good control of larval population of Thysanoplusia orichalcea. Imidachlorpid @ 250 ml/ha and Kamdhenukitnashi @ 1% and 2% were very effective treatments against whitefly. Seed treatment with the Thiamethoxam @ 3 g/kg seeds reduced the stem fly infestation effectively. Imidachlorpid @ 250/ha, indoxacarb @ 150 ml/ha and Kamdhenukitnashi @ 8% showed good performance against the girdle beetle infestation. Among different treatments Kamdhenukitnashi @ 2% and indoxacarb @ 150 ml/ha were comparatively safer for spiders while, Thiamethoxam seed treatment @ 3 g was safer for coccinellids. Maximum grain yield was recorded from the plots with chlorpyrifos seed treatment @ 4 ml/kg seeds. Also, treatments with Kamdhenukitnashi displayed some yield boosting chgaracteristics. Benefit cost ratio was higher in chlorpyrifos seed treatment and Kamdhenukitnashi spray @ 1, 2, 5 and 10%. Thus, from present investigation it is revealed that use of Kamdhenukitnashi can become a important eco-friendly components of the integrated pest management module for insect pests associated to soybean crop.

    Efficacy of some botanicals and other chemicals against Varroa jacobsoni (Oudemans) infesting Apis mellifera L. colonies in Pantnagar (Uttrakhand)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2007-07) Joshi, Kaushlesh; Srivastava, Poonam
    The mite Varroa jacobsoni Oudemans (Arachnida: Acari: Varroidae) now have serious problem in world beekeeping due to its parasitic relationship with Apis mellifera L. This mite was first described by Oudemans in 1904 from Apis cerana indica F. in Java/Sumatra (Indonesia) and in 1963 from A. mellifera in Philippines. The mite is brown, leathery in appearance and is 1.05-1.09 mm long and 1.50-1.58 mm wide. It feed on the haemolymph of the developing honey bee larva, pupa and the adult bee. The mite can easily penetrate the intersegmental membrane and gain access to the blood. It causes decreased brood and deformed bees which result in annihilation of entire bee stocks. Population dynamics studies revealed that varroa mite, V. jacobsoni had peak population during autumn season from 39th SW to 52nd SW, whereas lowest mite population was recorded in rainy season from 25th SW to 35th SW. However, the mite population in a hive greatly depends on temperature, time of the year, colony strength and brood area. A series of experiment were conducted the management of mite (V. jacobsoni) population in honey bee (A. mellifera) colonies with various botanical oils, plant extracts and some chemicals. The fumigation of different botanicals and formic acid were evaluated @ 5 ml per hive. The mean mortality varied significantly in different treatments. The overall mean mite mortality of 15 days showed that the eucalyptus oil, neem oil and formic acid gave better results. Studies on the effect of different plant extracts as dust revealed that maximum mite mortality was found with tobacco powder, sugar powder, wheat flour, sulphur dust and cumin powder. The spray of Tetmosol and acetic acid showed promising results for the control of V. jacobsoni in A. mellifera colonies. It was observed that the effect of spray of Tetmosol was significantly different from all other treatments which performed consistently better than other treatments. These oils, Plant extracts and chemicals can be applied singly or as a mixture of different compounds to improve efficacy. However the use of botanicals and plant extracts fit very well into Integrated Pest Management (IPM) program as alternating use of chemical control to avoid the development of resistance against varroa mite in honey bee colonies.

    The present investigation was carried out at CRC of Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, Distt. Udham Singh Nagar (Uttaranchal) to check the “Comparative effectiveness and compatibility of Neem Seed Kernel Extract with Synthetic and bio-pesticides and its efficacy with different additives against major insect pest of soybean.” Soybean is an important legume providing 43 per cent protein and 20 per cent oil. It is attacked by 273 insect pests, hampering the crop production. Thus it is necessary to control them. Result showed that NSKE 5 per cent with additives, synthetic and bio-pesticides proved to be some what effective in controlling leaf defoliators and also having impact to reduce adults while fly population and per cent plant infestation by stem fly and girdle beetle. The yield was higher in all the treatments than control so it can be concluded that all the treatments have some yield promoting capacity too. Neem seed Kernel Extract 5 per cent have showed better result when was used in combination with Dipel, triazophos and adjuvants like teepol, velvet and sandovit than alone. NSKE 5 per cent with Dipel effectively controlled the larvae of Spilarctia obliqua, and with triazophos reduced the population of Spodoptera litura, Thysanoplusia orichalcea and stem fly infestation. NSKE 5 per cent with teepol & velvet the population of Thysanoplusia orichalcea and girdle beetle infestation, respectively. Thus, looking into the over all picture of the present investigation and need of the time, it can be concluded that NSKE 5% fortified with sandovit, NSKE 5% mixed with Dipel and also the NSKE 5% itself can become a important eco-friendly components of the integrated pest management module for insect pests associated to soybean crop.

    Field screening of 22 International Nursery chickpea genotypes and 33 least susceptible genotypes along with check cultivars against H. armigera was carried out at Crop Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar during Rabi seasons of 2004-05 and 2005-06. Screening under natural filed conditions revealed that among 22 least susceptible chickpea genotype and mean egg population/plant varied between 1.0 and 3.1 during Rabi 2004-05, while in Rabi 2005-06 egg population/plant varied between 1.2 and 2.5 eggs/plant. The mean larval population varied between 2.5 and 4.5 larvae/plant during 2.004-05 and 1.7 and 3.3 larvae/plant during 2005-06. Among 33 least susceptible chickpea genotypes the egg population per plant varied between 1.7 to 3.1 eggs/plant during Rabi 2004-05. During 2005-06 the egg population varied between 1.5 to 2.8 eggs/plant, whereas the mean larval population varied between 3.4 to 6.4 larvae/plant during 2004-05 and 2.4 to 5.2 larvae/plant during 2.005-06. Mean pod borer damage in case of 22 least susceptible genotype varied from 54.0% to 76.9% and in case of 33 least susceptible genotypes it varied from 12.0% to 49.9% screening lead to the identification of RIL 85, RIL 51, ICC 67, ICC 16261 and ICC 506 as less susceptible. In case of 33 least susceptible genotypes, IC 269160, IC 269161, IC 269272, IC 269307, IC 269375 and IC 269399 were found to be least susceptible. Rest of the genotype were reported either moderately susceptible or highly susceptible against H. armigera. Grain yield obtained during 2005-06, ranged from 1185.2 kg/ha to 3148.1 kg/ha in case of 22 least susceptible genotypes. In case of 33 genotypes, it ranged from 9.3 to 29.8 g/6 plants. The cultivars, RIL 51 and IC 269327 gave significantly greatest grain yield. The results of laboratory experiments showed that among 22 selection chickpea genotypes maximum larvae, 68.0% survived on ICC 16207 and minimum 20.0% on ICCC 37. The larval period varied from 13.0 days to 15.6 days and larval weight ranged from 0.12 g to 0.18 g. Pupation varied from 40% to 60% and pupal weight varied from 0.16 g to 0.22 g. Among 33 least susceptible chickpea genotypes, maximum larvae 72.5% survived on IC 269159 and minimum 45.0% on IC 269160, IC 269161 and IC 269195. The larval period varied from 13.0 days to 15.6 days and larvae weight ranged from 0.64 g to 1.14 g. Pupation varied from 40% to 80% and pupal weight varied from 0.15 g to 0.26 g. The entries RIL 5\85, RIL 51, ICC 67, ICC 16261, ICC 506, IC 269311 and IC 269375 proved resistant on the basis of multicomponent analysis and can be used as sources of resistance against H. armigera.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2006-06) Madhukar, Firake Dnyaneshwar; Karnatak, A.K.
    The experiments were conducted in rice variety Pant Dhan – 4, at Crop Research Centre of G. B. Pant University of Agriculture & Technology, Pantnagar, during Kharif, 2005. Several experiments were carried out preparing to behavioural activities of rice pests in respect of their eco-friendly management. It was observed that, the yellow stem borer population had two peaks, one at middle of crop growth period and other at following stage of crop. Maximum activity of leaf folder, brown plant hopper was observed from end of August upto middle of September while highest incidence of green leafhopper observed from second week of August upto first week of September. The spiders and Coccinellids were significantly visible from end of June and its population reached to highest peak during end of August. Among various plant extracts, Neem seed extract (2%) was observed as most superior and had significant effect on both rice pests and natural enemies while camphor extract (2%) was least effective. Regent was most effective against yellow stem borer while Dimilin showed better results against leaf folder. Confidor and Regent were found most superior against hoppers. Dipel was safest insecticide for Coccinellids and spiders while Dimilin was found harmful for them. Thimet was least effective against rice pests but had adverse effect on natural enemies.

    Value addition in apicultural products
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2006-07) Bira, Lawate Bhiva; Mall, Pramod
    The experiments were conducted at Apiculture Laboratory, Department of Entomology and some analytical work was done at Food Processing Lab., Department of Post Harvest Processing and Food Engineering, College of Technology, G.B. Pant University of Agriculture & Technology, Pantnagar. Several experiments were carried out pertaining to fermentation of honey with wine yeast Saccharomyces cerevisiae to produce alcohol and purification of propolis with different solvents viz; ethanol, glycol, mustard oil and water. Organism used for fermentation after activation in YPD broth medium. Readings of alcohol production and residual sugar were recorded at pH 3.8, 4.0, 4.2 and natural pH at 24 hrs, 48 hrs, 72 hrs and 96 hrs of time interval of fermentation of honey with respect to various sugar concentrations viz; 7, 9, 11, 13, 15 per cent. Propolis extraction was recorded at different time intervals by using different solvents. In this investigation it was found that alcohol yield increases with increase in sugar percentage up to certain limit, further increase in sugar concentration hamper alcohol production. It was observed that out of all tested pH, pH 3.8 was most suitable pH where maximum alcohol was produced. Out of different honey concentrations, 13 per cent concentration was optimum to get maximum alcohol. This was again obvious that alcohol fermentation declined consistently with decreasing per cent sugar. However, at higher sugar concentration (15 per cent), yeast showed inhibitory effect on alcohol formation. Alcohol production was found at high rate up to 72 hrs of time interval. Overall maximum fermentation efficiency was recorded at 13 per cent sugar concentration at all pH except 4.20. The maximum residual sugar was found at 15 per cent sugar concentration, irrespective of pH and time interval. In case of propolis purification, ethanol found to be most efficient solvent and showed proportionate maximum effect within three days, Propolis extraction efficiency of used solvents were in order: ethanol > glycol > mustard oil > water.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2006-07) Joshi, Basant; Singh, C.P.
    During the investigation on bioactivity of nine medicinal and aromatic plant oils against Spilarctia obliqua (Walker), (Arctiidae: Lepidoptera), the plant oil of Cymbopogon martini and Cymbopogon citratus grouped under extreme antifeedant class at 1, 3, and 5 percent oil concentration. Whereas the plants oil of Eucalyptus globulus, Mentha spicata and Pelargonium odoratirum grouped under moderate antifeedant class at 3% oil concentration. And Mentha arvensis, Mentha pipperata and P.odoratirum grouped under strong antifeedant class at 3% concentration. E. globulus, C.nardus and M. spicata showed moderate antifeedant activity at the same. Lowest LC30, LC50 and LC90 (highest toxicities) was found in oil of A. indica after 6, 12, 24, 48 and 72 hour of acute exposure and highest LC30, LC50 and LC90 (lowest toxicities) was found in oil of M. pipperata, C. martini, M. spicata and P.odoratirum. Highest larval weight gain was found when larvae fed on M. arvensis treated oil and lowest in C. citratus and A. indica. Highest pupal weight was found in E. globulus, & M.arvensis and lowest C.citratus and A. indica. Maximum mean larval and mean pupal period was found in C. martini and C. nardus while minimum in C.citratus, whereas highest percent pupation and adult emergence was found in E. globulus and lowest in C. martini and C. nardus. Highest percent egg laying was found in M. pipperata, C. martini and M.arvensis treated oil and lowest was found in C. martini, C. nardus and C. citratus at 0.25%, 0.5% and 1.0% concentration. Highest percent hatching was found in C. citratus and M.spicata treated oil and lowest in E. globulus and P. odoratirum treated oil. While maximum incubation period was found on M. spicata, E. globulus and minimum in C. citratus, M. arvensis, C. martini and E. globulus. Larval pupal deformities were found in C. martini; C. citratus, C. nardus and A. indica and highest adult deformities were found in C. citratus A. indica and C. nardus. while highest total deformities was found in C. citratus. Thus it is clear that plant oils affect the egg laying, feeding, growth and development of Spilarctia obliqua (Walker).

    biodiversity, Syrphid, pollinators, mangoes, predators, aphids, Uttarakhand
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2005-06) Thakur, Manju; Avdhesh Kumar
    The syrphid flies (Diptera:syrphidae)are one of the most diverse flies of the world ,comprising about 200 genera and over 5000 species .Hoverflies adults display wide range of lifestyle and adaptations. Adult of aphidophagous species are frequent flower visitors ,certain species are predominantly nectarivorous, whereas others are pollinivorous .Adult require honeydew or nectar and pollen to ensure reproduction ,whereas larvae require aphids to complete development syrphus sp. has been observed as the major insect pollinators associated with mango, pollination of flowersrequire insects. The mango belongs to the family Anacardiaceae which is a dicotyledonous family consisting of 64 genera. cross pollination occurs in mango flowers therefore a pollinizer is required. The effective insect pollination is essential for good fruit set and yield in mango (Mangifera indica) Present investigation was therefore, initiated to assess the role of syrphid flies as major insect pollinators in fruit set of mango. For this purpose 30 years old mature mango trees c.v. Dashehari were selected and 20 panicles were bagged. 3 panicles in one bag 0, 5, 10, 15, and 20 syrphid flies were released into each bag respectively at the time of peak bloom. At the time peak bloom different insects were collected with the help of hand net and identified. The activity of syrphid flies was also observed. The number of syrphid flies per panicle, the number of flowers visited per minute and the time spent per flower were checked. Further the role syrphid flies in fruit setting quantity was assessed by counting the number of fruit set and fruits matured in all the six treatments. The quality parameters were determined by testing for the TSS content, fruit size, fruit weight, amount edible pulp. The quantity parameters were determined by testing the number of fruits at different sizes viz. pea size, marble size and full size fruits. The highest number of insects visiting the mango flora belonged to the family syrphidae. Six species Syrphus corollae, Episyrphus balteatus, Melanostoma orientale, Eristalis sp., Ischiodon scutellaris, Syrphus isaaci were found frequently in Pantnagar and were found as the efficient pollinators of various agricultural, horticultural, ornamental, oil seed crops. The highest number of flies were observed between 0900-1000 h, they spent more time per flower an visited maximum number of flowers early in the morning between 0700-0800h. In fruits, that were set under open pollinated conditions where syrphid flies population was maximum, high results were obtained with TSS, fruit size and fruit weight while low results with seed size and peel. Thus, it can be concluded that syrphid flies has greatest potentialities for use in controlling of aphid pests of crops in Pantnagar.
