Dr. Y. S. Parmar University of Horticulture & Forestry, Solan

Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Solan, was established on 1st December, 1985 with the objective to promote education, research and extension education in the fields of Horticulture, Forestry and allied disciplines. Late Dr. Yashwant Singh Parmar, the first Chief Minister and the architect of Himachal Pradesh perceived the importance of Horticulture and Forestry to develop and improve the State economy which led to the establishment of this University. Its history lies in erstwhile Himachal Agricultural College, Solan, established in 1962 and affiliated to the Panjab University. It became one of the campuses of Agriculture Complex of Himachal Pradesh University on its formation in 1970. Consequent upon the establishment of Himachal Pradesh Krishi Vishvavidyalaya in 1978, this campus became its Horticulture Complex and finally in 1985, assumed the status of a State University, being the only University in the country engaged exclusively in teaching, research and extension in Horticulture and Forestry. The University is located at Nauni in Solan District of Himachal Pradesh, 13 km from Solan on Solan-Rajgarh Road, at an elevation of 1300 metres above mean sea level. Solan town is situated on national highway (NH-22) and is well connected by train and bus services. The University has four constituent colleges, out of which, two are located at the main campus Nauni, one for horticulture and the other for forestry, having 9 and 7 departments, respectively. The third College i.e., College of Horticulture & Forestry is located at Neri in Hamirpur District on Nadaun-Hamirpur state highway, about 6 Km from Hamirpur town and is well connected with bus service. The college offers three Undergraduate Degree Programmes i.e. BSc (Hons.) Horticulture, BSc (Hons.) Forestry and B. Tech. Biotechnology and MSc degree programme in a few subjects. The fourth college i.e. College of Horticulture and Forestry, Thunag (Mandi) is located at Thunag District Mandi. This college offer BSc (Hons.) Horticulture and BSc (Hons.) Forestry degree programme. In addition, there are five Regional Research Stations, 12 Satellite Stations and five Krishi Vigyan Kendras (KVKs) situated in different zones of the State.

    STUDIES ON GENETIC DIVERSITY OF DIAMONDBACK MOTH, Plutella xylostella, (L.) (Lepidoptera) IN NORTH INDIA
    (UHF,NAUNI, 2017-10) ARVIND, KUMAR; RANA, RAJINDER SINGH
    ABSTRACT Geographic variations among different populations of Plutella xylostella collected from eight different locations viz. Solan, Palampur and Theog (Himachal Pradesh), Fatehgarh Sahib (Punjab), Sharnapur (Uttar Pradesh), Pantnagar (Uttarakhand), Hisar (Haryana) and Delhi were studied. Standard molecular technique RAPD-PCR was also utilized to study the variations among different populations. In addition to this the variations regarding different biology and life tables were investigated in the laboratory. The RAPD-PCR studies were conducted with 20 random primers out of which 12 produced amplified PCR products. A total of 73.03 per cent polymorphism was observed among eight populations of P. xylostella. 100 per cent polymorphism was observed with OPA-16 and OPAB-10 primers whereas, minimum polymorphism (40.00%) was observed in OPD-14 which produced 5 amplified bands. The values of similarity coefficient ranged from 0.50 to 0.70. Maximum similarity was observed between Solan and Theog populations (70.00), whereas, minimum similarity was observed between Delhi and Pantnagar populations of P. xylostella. The total developmental period was minimum in the Fatehgarh Sahib population (13.74 days) followed by the Theog, Pantnagar, Saharanpur, Solan, Delhi and Hisar, Palampur populations (14.72, 15.00, 15.73, 15.85, 16.92, 17.20 and 17.65 days, respectively. The life table studies revealed that the intrinsic rate of natural increase (rm) was the highest in the Theog population (0.242) followed by the Palampur (0.236), Saharanpur (0.232), Fatehgarh Sahib (0.221), Pantnagar (0.218), Solan (0.211) and Delhi (0.195) population, whereas it was least in the Hisar population (0.189). Continuous exposure of indoxacarb and chlropyrifos may result in biologically superior strain of diamonback moth as revealed by the increase in LC50 value from 17.06 ppm to 43.07 ppm for Solan and 21.70 ppm to 60.53 ppm to Fatehgarh Sahib population with 2.56 and 2.80 folds as compared with parent generation for indoxacarb. LC50 value increase from 102.67 ppm to178.61 ppm for Solan and 155.81 to 248.15 ppm with 1.74 and 1.59 folds as compared with parent generation for chlorpyrifos.

    BIO-EFFICACY OF SOME INSECTICIDES AGAINST GREENHOUSE WHITEFLY Trialeurodes vaporariorum (Westwood) ON TOMATO
    (2013) ARVIND, KUMAR; CHANDEL, RPS
    ABSTRACT The present investigations entitled “Bio-efficacy of some insecticides against greenhouse whitefly Trialeurodes vaporariorum (Westwood) on tomato” was carried out during 2010-2012 in the Department of Entomology, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan (HP). Laboratory experiments were carried out to study the efficacy of six insecticides namely oxy-demeton methyl, spiromesifen, cyantraniliprole, chlorfenapyr, buprofezin and diafenthiuron and two botanicals azadirachtin (Neem Baan 1500 ppm) and dharek extract against first instar nymphs of the greenhouse whitefly, T. vaporariorum. Among chemical insecticides, spiromesifen had the maximum efficacy against the test insect with LC50 value of 2.72 ppm followed by cyantraniliprole (9.80 ppm), diafenthiuron (18.91 ppm), chlorfenapyr (22.63 ppm), buprofezin (31.45 ppm) and oxy-demeton methyl (206.99 ppm). The LC90 values were 13.48, 47.79, 68.41, 85.60, 168.65, and 1148.15 ppm for spiromesifen, cyantraniliprole, chlorfenapyr, diafenthiuron, buprofezin, and oxy-demeton methyl, respectively. Bio-pesticides, azadirachtin (Neem Baan) and dharek extract resulted in dosage-dependent mortality with LC50 and LC90 values of 4.45 and 27.58 ppm and 2.84 and 8.60 per cent respectively. The field efficacy of six insecticides and two botanicals revealed that cyantraniliprole (0.01%) was most effective in controlling T. vaporariorum followed by chlorofenapyr (0.022%) whereas, spiromesifen (0.0015%) and azadirachtin (0.00045%) were observed least effective. The study on repellency of botanicals revealed that dharek extract at 7 per cent gave highest repellency of crawlers of the whitefly
