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 comparative efficacy of some synthetic insecticides, phytoproduct and biopesticides against brinal fruit and shoot borer, Leucinodes orbonalis Guen. and hadda beetle, Epilachna vigintioctopunctata Fab. in brinjal at Pantnagar
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2013-08) Bahuguna, Swati; Srivastava, Poonam
    Twenty-eight species of insects belonging 10 different orders and 20 families were encountered to know the diversity of insect fauna associated with brinjal crop. Among the various insect pest of brinjal, the brinjal shoot and fruit borer (L. orbonalis) and hadda beetle (E. vigintioctopunctata), have been recorded as the most prevalent species as evidenced by their activity period at Vegetable Research Centre, Pantnagar The relative efficacy of each treatment was assessed on the basis of per cent pest reduction over control where the per cent reduction of larval population over control was recorded and observed to be highest in lambdacyhalothrin at 4 ml/lt with 54.50 percent which is highest percent in reduction of larval population after 3rd application followed by the lambdacyhalothrin at 0.56, 1.38, 0.69 and 0.81 ml/lt with 53.10, 52.00, 50.90 and 48.86 per cent over B. t. (Halt), B. b. (Biosoft) and neem at 2ml/l with 39.00, 35.80 and 34.70 per cent respectively. The percent reduction of hadda beetle population was recorded highest in chlorpyriphos, quinalphos, carbaryl at 2ml/lt, lambdacyhalothrin at 1.38, 0.69 and 0.56 ml/lt range from 78.33-53.33 per cent. However, the lowest percent of reduction was recorded in the treatment B. t. (Halt), B. b. (Biosoft), neem and malathion at 2ml/l, lambdacyhalothrin at 0.81 and 4ml/lt 51.66-31.66 per cent. The safety of the treatments for the natural enemies viz., Coccinella septumpunctata, Chrysoperla carnea, spider and Eucanthecona bug were observed and the results revealed that the highest population of natural enemies was found in untreated check (T13), as it was the complete safest treatment for all natural enemies followed by neem, B. t. (Halt) and B. b.(Biosoft) at 2ml/lt indicating partial safety of the treatment whereas, lambdacyhalothrin at 0.56, 0.69, 0.81, 1.38 and 4ml/lt, chlorpyriphos, quinalphos, carbaryl and malathion were recorded with lowest number of natural enemies indicating no safety of the treatments. The highest yield of brinjal was recorded in lambdacyhalothrin at 4 ml/lt (204.16 kg/ha) with per cent damage of (28.00) followed by lambdacyhalothrin at 1.38, 0.69, 0.81 and 0.56 ml/lt with 197.22, 190.27 and 170.83 kg/ha and a per cent damage of (32.51, 35.30 and 38.70) respectively. Whereas, B. b. (Biosoft) at 2ml/lt was recorded with lowest yield100.38 kg/ha and a per cent damage of (87.00).

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2013-06) Shivashankara; Srivastava, R.M.
    The studies on “Role of insect pollinators in coriander seed production” was carried out during 2012-13 at G.B.P.U.A & T. Pantnagar, Uttarakhand, India, to study role of insect pollinators in coriander seed production. The mean abundance of honeybees was highest with 3.1 bees/min/ m2 at 12 PM and followed by 2.36 bees/min/ m2 at 3 PM and least was 1.16 bees/min/m2 at 10 AM. Its population was highest in the variety COR 44 with 4.93 and least in the variety COR 36 with 0.53. In case of Syrphids, the mean abundance of syrphids is highest at 10 AM i.e. 5.22 syrphids/min/ m2 followed by 4.34 syrphids /min/m2 at 3 PM and least at 10 AM was 3.81 syrphids /min/ m2 . It was highest in the variety COR 38 with 12.07 and least was zero in two varieties. The pollinators of coriander belong mainly to four orders viz., Hymenoptera, Diptera, Lepidoptera and Coleoptera. Important species visiting the coriander viz., Apis dorsata, A. cerana indica, Apis mellifera, Apis florea, Episyrphus balteatus, Eristalis tenax and, syrphus spp., Musca spp. and other Dipteran flies of which, A. cerana indica was more dominant followed by Apis dorsata but in Syrphids Episyrphus sp. was more dominant. The flowering period for the varieties COR 37 and COR 36 was 18 days; COR 55 was 28 days and 30 days for all other varieties. The foraging speed of honey bees viz., Apis dorsata and A. cerana are 11.22 seconds and 3.473 respectively. The foraging rate of Apis dorsata and A. cerana, are 13.53 and 23.43 umbels/ minute by Apis dorsata and A. cerana respectively. The foraging mode observed in bee, which was carried both pollen load and nectar in their visit but syrphids were nectar feeder only. Syrphid started foraging (8.23 AM) much earlier than the honeybees i.e.10.13 AM and 10.14 AM for Apis dorsata and A. cerana respectively. The bee, Tetragonula laeviceps was not involved in the pollination of the coriander. Pollen carrying capacity of the Apis dorsata was highest followed by A. cerana, the mean relative abundance of pollen is 2.43 ×104pollens/ml and 1.63×104pollens/ml for Apis dorsata and A. cerana, respectively. The cross pollination plots were showed higher yield than the caged plots, the 9 varieties which were pollinated by insects given tremendous increase in the yield. The mean % increase of yield in all varieties is 243.02%. The percent of yield increase was highest in COR 44 (308%) followed by COR 49 (303.81%) and least in COR 38 (177.5%).

    Screening of tomato germplasm/variety against tomato fruit borer Helicoverpa armigera (Hub.)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2013-06) Bhatt, Lata; Srivastava, R.M.
    The present experiment was conducted from January-June, 2013 at Vegetable Research Centre (V.R.C), of Govind Ballabh Pant University of Agriculture & Technology, Pantnagar (Uttarakhand) for screening of tomato germplasm/variety against tomato fruit borer Helicoverpa armigera (Hub.). The field experiment was laid out in Randomized Block Design with 29 genotypes along with one check in three replications. Observations were recorded during the experiment on the following parameters viz., abundance of egg laid by Helicoverpa armigera, larval population of H. armigera, per cent fruit infestation due to H. armigera, moth catches in pheromone trap and abundance of trichomes on tomato leaves. Results of the present investigation revealed that none of the screened germplasm/variety was found highly resistant to the fruit borer, Helicoverpa armigera. Percentage fruit damage ranged from 4.57% on Cherry Sutton to 32.43% on EC-519800. Cherry Sutton, Wild Type Tomato, PT-1, Arka Vikas, Shirozi, ARTH-3 and PT-2009-02 were least infested (0 to 10%) and classified as resistant genotypes. EC519800 and PT-2009-10 which registered 31 to 40 % fruit infestation were rated as susceptible genotypes. 12 genotypes were rated as moderately resistant and 9 genotypes as moderately susceptible. On the basis of study conducted, trichome density/unit area (mm2) on the leaves was found to have significant effect on H. armigera damage. Significant variations were recorded for trichome density among tomato germplasms both on upper and lower leaf surface. Between the leaf surfaces, lower surface recorded higher trichome density than upper leaf surface. The trichome density on upper and lower leaf surface showed significant positive correlation with the abundance of eggs. The results thus indicate that Shirozi, PT-1 and Cherry Sutton were found superior over other germplasms whereas PT-2009-10 showed high susceptibility towards tomato fruit borer, H. armigera.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2013-07) Joni Kumar; Mall, Pramod
    The present investigations were carried out in apiary, Department of Entomology, G. B. Pant University of Agriculture and Technology, Pantnagar (Udham Singh Nagar) Uttarakhand. Present studies deals with a particular continuous observation of honey bee colony at every 14 days interval. Colony activity viz. honey, pollen, sealed brood, bees strength (NBF) and cleanliness traits from fifteen colonies were observed using sq. inch (in2) wire grid method. During the course of investigation, the most prolific queen was identified on the basis of maximum eggs area recorded in C12 (52.50 in2) and C11 (45.00 in2). In respect of larval area, the maximum area was observed in C11 (132.56 in2), C1 (104.50 in2) and C12 (93.00 in2) colonies. The colonies no. C12 (220.25 in2), C11 (189.50 in2) and C14 (176.00 in2) had maximum brood rearing activity. The maximum bees strength was recorded in C1 (8.00 NBF) followed by that in C2, C5, C8 and C14 (7.00 NBF) colonies and these colonies can be included in breeding programme considering the good strength. As far as honey area is concerned, the maximum honey was stored in C1 (464.00 in2) and C2 (245.00 in2) colonies hence categorized as good honey gathering colonies. Considering the pollen area, the colonies C5 (75.00 in2), C4 (65.50 in2) and C1 (58.00 in2) had maximum pollen store. On the basis of collecting debris, the maximum cleanliness was observed in C15 (5.22gm), C8 (4.50gm) and C11 (3.48gm). Evaluation of colonies for the hygienic behaviour was done by using the methodology “pin killed method”. The pin killed brood cells were marked for the purpose of identification and the maximum cleaning was observed in C1 (100%), C14 (94.25%) and C2 (93.77%) colonies hence they can be used for further breeding programme to strengthen diseases and pests resistance trait. The technique of larval grafting was adopted for queen rearing. The maximum no. of acceptance was recorded in C2 (23.00) and C1 (22.00) colonies. In respect of no. of sealing, the maximum no. of sealing was observed in C1 (19.00 out of 22.00 cells) and C2 (19.00 out of 23 cells), whereas, the maximum no. of emergence (15) was recorded in C1 and C2 colonies. In this study the increase or decrease weight of pre and post mating was observed. The queens were weighed 3 times i.e. three days after emergence; one day after the mating and after start of egg lying. The maximum weight of queen was recorded after the onset of oviposition (215.85mg) in C4 colony. The overall maximum average weight was recorded in C4 (203.50mg) and C7 (197.80mg) colonies. The effect of harvesting time (48, 72 and 96h) on production of royal jelly was studied by grafting about 24h old larvae. The maximum production of royal jelly was recorded when it was harvested from queen cell cups after 72h of grafting.

    Screening of some soybean germplasm against pulse beetle, Callosobruchus chinensis (Linnaeus)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2013-07) Vishwakarma, Asha; Gaur, Neeta
    Laboratory experiments were conducted in IPM laboratory, Department of Entomology of G.B. Pant University of Agriculture and Technology, Pantnagar during the year 2012-13. Observations under protected laboratory condition indicated that, none of the gemplasm was found to be highly susceptible. These germplasm were compared on the basis of egg laying, developmental period, growth index, percent adult emergence, percent weight loss, percent infestation and susceptibility index. Females of C. chinensis oviposited on all 41 germplasm that were tested in the laboratory but oviposition behaviour was unrelated to the host suitability for bruchid development. The germplasm AMS MB 5-19 (17.00eggs/20 g seeds) was least preferred for oviposition, while PS 1477 (74.67 eggs/20 g seeds) was most preferred. A positive correlation was found between oviposition and seed size. The germplasm KDS 8, MACS 1336 and PS 1477 were highly preferred for adult emergence, percent adult emergence, growth index, percent weight loss and percent infestation. Adult emergence showed negative correlation with seed coat thickness and hardness. Susceptibility index ranged from 0 to 8.81. The results indicated that germplasm BAUS-40, DSb-18, DSb-19, DSb-20, KDS-8, SL-778, KDS-701, MACS1336, MACS-1340, PS 1477 and VLS 76 were moderately resistant while others were resistant. Results of screening of forty one soybean germplasm against C. chinensis indicated that RKS 63 followed by NRC 86 and AMS 56 were the least preferable due to lowest growth index, minimum percent seed weight loss and lowest susceptibility index. The developmental studies under laboratory conditions showed that egg to adult took maximum 47 days and this period increased by most preferred to least preferred soybean germplasm.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2013-05) Usha; Srivastava, Poonam
    Studies on the impact of insect pollination in mango with different objectives like pollinators fauna, foraging activity, mode of pollination and influence of bee repellent for enhancing the quality and quantity of mango fruits were carried out at Horticulture Research Centre, Patharchatta, G.B.P.U.A.&T., Pantnagar during the year 2011 and 2012. The major insect pollinators found visiting on mango inflorescences were Episyrphus balteatus DeGeer, Melanostoma orientale We., Syrphus corollae Fab., Eristalis tenax L.(Diptera : Syrphidae) Apis dorsata Fab., A. mellifera L., A. cerana indica Fab., Tetragonula laeviceps, Xylocopa aestuans L., Musca domestica L., Musca. sp., Eupeodes sp., Calliphora sp. and Chrysomya sp. The activity of foragers were started in the month of march with initiation of flowering with a peak of 22.64 syrphid flies/panicle/5min, 20.54 A. mellifera, 7.84 A. dorsata, 2.98 A. c. indica and 3.84 non apis bees on 15th march, 2013. However, the maximum foraging activity of pollinators was recorded in morning hours at 10.00AM with 20.34 syrphid flies/panicle/5min, 21.81 A. mellifera/panicle/5min., 9.66 A. dorsata/panicle/5min, 9.28 A. c. indica/panicle/5min and 4.16 non apis bees/panicle/5min. visiting on mango flowers. Maximum number of A. mellifera was recorded on mango trees at 25 m distance away from the hive (20.33 bees/m2/10min) at 1200-1300 hr, while minimum (6.26 bee/m2/10min) at 175 m distance at 1500-1600 hr. The syrphid flies were found to forage maximum number of flowers (17.82 flowers/syrphid flies/5 min) from 0900-1100 hr. Whereas, A. mellifera spent maximum time 14.98 Sec./flower at 0900-1100 hr. Various modes of pollination had a significant effect on the quality and quantity of mango fruits. Highest fruit setting (2.12 per cent) and yield (22.26 kg/tree) were recorded in the treatment T3 (open pollination) followed by the treatment T1 (A. mellifera boxes) with 18.20 and T4 (Tetragonula laeviceps boxes) with 18.12 kg/tree, respectively. However, qualitative parameters viz. size of the fruit, TSS, Dry matter per cent, Ash content and Moisture per cent of mango fruits were higher in bee pollinated trees. Highest efficiency was observed in Cheed oil, Devdar oil, Camphur oil, Dhoop oil, Patcholi oil, Mustard oil and Van tulsi oil as bee repellent where none of the bee visited on the surface treated with these oils.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2013-08) Selvaraj, S.; Bisht, R.S.
    The present investigation was carried out during 2011-12 and 2012-13 at Vegetable Research Centre, G.B. Pant University of Agriculture and Technology, Pantnagar situated in Tarai region of Uttarakhand. A total of ten species of insect pest belonging to four categories viz., Defoliators (3 species), sap suckers (5 species), miner (1 species) and borer (1 species)have been observed to attack tomato crop. The order Hemiptera occupied the largest number of species contributing about 34.21% of the total pest followed by Lepidoptera (28.95%), Diptera (14.47%), Coleoptera (7.89%), Orthoptera (6.58%), others (5.26%) and Thysanoptera (2.63%). Among the various insect pests of tomato, Helicoverpa armigera, Liriomyza trifolii, and Bemisia tabaci have been reported to be major insect pests. The incidence of H. armigera on tomato during the cropping season 2011-12 and 2012-13 revealed that the pest marked its first appearance in 7th and 9th standard meteorological week (SMW), attain peak population in 16th and 15th SMW, respectively. Whereas, first appearance of leaf miner at 9thand 8th SMW, attain peak population in 14th and 17th SMW, respectively. The life history of tomato fruit borer studied in laboratory revealed that female laid 180 to 260 eggs and 410 to 450 eggs during her life span on natural and synthetic diets, respectively. The incubation period, duration of different instars, pupal period and adult longevity have been observed to be 3-5 days, 20-25 days, 10-12 days and 5-6 days, respectively on natural diet whereas, 3-5 days, 25-28 days, 11-14 days and 7-9 days, respectively on semi synthetic diet. During both the cropping season, the treatment chlorantraniliprole 4.3% + abamectin 1.7% SC at 30 g ai/ha has been found most effective insecticides against the population of H. armigera, L. trifolii and B. tabaci followed by chlorantraniliprole 4.3% + abamectin 1.7% SC at 60 g ai/ha. Minimum per cent fruit damage (5.25 and 4.71%) and maximum fruit yield (28.89 and 31.24 t/ha) was also recorded with chlorantraniliprole 4.3% + abamectin 1.7% SC at 30 g a.i/ha during both the cropping seasons 2011-12 and 2012-13, respectively. However, chlorantraniliprole 4.3% + abamectin 1.7% SC at 24 and 30 g ai/ha appeared to be the safest treatment for existing natural enemy population.

    Population dynamics of insect pests and pollinators associated with Litchi chinensis Sonn.
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2013-06) Joshi, Sanjay Kumar; Singh, C.P.
    The leaf infestation pattern as well as population dynamics of five different foliage feeders (Statherotis leucaspis Meyrick, Dudua aprobola Meyrick, Acrocercops cramerella Snellen, Popillia japonica Newman and Weevils) was observed in litchi crop at Horticulture Research Centre Pattharchatta during 2011-013. The incidence of all insect pests once in a year except in leaf roller where it was twice in a year. The incidence of all the pests was maximum in East direction and minimum incidence was recorded in North direction. The population as well as leaf infestation was minimum in high density orchard (1.0 × 0.5 Metre). Low density orchard (8.0 × 8.0 Metre) was preferred for maximum infestation by all pests. The abiotic factors (Temperature and Relative humidity) had significant impact on pest incidence. Rainfall was a limiting factor for all the insect pests. The relative abundance of different insect pollinators during the flowering season was found maximum in the end of March in East direction. The maximum abundance of Apis mellifera (3.1 and 4.2 foragers/inflorescence/3minute), Apis dorsata (1.4 and 0.8 foragers/inflorescence/3minute) and Syrphid flies (10.4 and 0.9 foragers/inflorescence/3minute) was recorded at 1100 hours during the year 2011 and 2012 respectively. The maximum abundance of Trigona laeviceps Smith and Coccinella septempunctata was in the evening hours (1400 and 1700 hours). The surrounding environment of inflorescence had more impact on the relative abundance of pollinators than the open environment of location.

    Seasonal incidence and screening of soybean cultivars and efficacy of chlorantraniliprole 18.5 SC against major insect pests
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2013-07) Mathur, Vaibhav; Bisht, R.S.
    The present investigation was carried out during kharif 2011 and 2012 at Norman E. Borlaug Crop Research Centre, G.B. pant University of Agriculture and Technology, Pantnagar situated in Tarai region of Uttarakhand. The study incorporates the results on the pest complex, relative abundance and seasonal incidence of insect pest of soybean and screening of some germplasm against major insect pests of soybean. Besides, the efficacy of a newer insecticide, chlorantraniliprole 18.5 SC (Coragen) was also tested against the soybean defoliators viz., Spilarctia obliqua, Spodoptera litura and Thysanoplusia orichalcea and the borer, Riptortus linearis. Considering the pest complex of soybean in the present study the order Hemiptera occupied the largest number of species constituting about 37% of the total pest, followed by Lepidoptera (25%), Coleoptera (25%), Diptera (6%), Orthoptera (2%) and others (5%). A total of seventeen insect pests were found to attack soybean crop belonging to three categories viz., defoliators (7 species), sap sucker (8 species) and borer (2 species). Among the various insect pest of soybean, Melangromyza sojae (borer) has been reported to be most predominant followed by Bemisia tabaci (sap sucking). Out of 43 cultivars screened against 7 major insect pests of soybean the cultivars JS-20-34 and AMS-MB-5-18 were identified to be resistant and AMS-MB-5-18, CSB-08-09, CSB-08-08, RKS-63, JS-20-29, DSb-20, MACS-1281, JS(SH)2003-8, SL-794 and MACS- 1140 were identified as the moderately susceptible (MS) against defoliator pests. CSB-08-09 was observed to be resistant to stem fly infestation but highly resistant to B.tabaci. The KDS-344 was found to be highly resistant against borer viz., Obereopsis brevis. Chlorantraniliprole 18.5 SC has been found effective against the defoliators viz., S. obliqua, S.litura and T.orichalcea and the borer, R.linearis over control. However, this insecticide appeared to be most promising to combat the larval population of T.orichalcea. The cultivars PS-1466, PS-1477, DS-12-5 and SL-795 were found to be resistant and high yielding during present study.
