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.

    BIODIVERSITY AND SYSTEMATIC STUDIES OF THE LEAFHOPPER (CICADELLIDAE: HEMIPTERA) FAUNA OF HIMACHAL PRADESH
    (UHF,NAUNI, 2019-07) THAKUR, PRIYANKA; RANA, RAJINDER SINGH
    ABSTRACT Himachal Pradesh is one of the hubs of biological diversity with varied agro climatic conditions and elevation ranging from 350 to 7000m amsl. The congenial atmospheric conditions are the natural abode and homeland for large number of insects. Despite being one of the most diverse habitats, several insect families remain poorly studied in the state. Cicadellidae one of the largest insect families of order Hemiptera distributed worldwide is one among them. The diversity, species richness, abundance and distribution pattern os f leafhopper speciein all the four agro-climatic zones of the state was explored. The sweep net as well as light traps were used for collecting leafhoppers from all the 12 districts of the state covering 25 locations. A total of 85 leafhoppers species belonging to 61 genera of 12 subfamilies of Cicadellidae were recorded. Of these four species, Gurawa monorcephala Pruthi, Leofa pulchellus Distant, Olidiana kirkaldyi (Walker) and Paralimnellus cingulatus (Dlabola) from subfamilies appeared to be new records from Himachal Pradesh and one species, Pseudosubhimalus sp. 1 was recorded to be new from India. Species richness of leafhopper species increased with the altitude with a hump of the highest species richness as well as diversity in the mid hills zone (651-1800m amsl) following declining trend towards the cold dry zone. Morphological characters taken under consideration for identification of leafhopper species which included: crown, face, compound eyes, ocelli, frontoclypeus, pronotum, scutellum, hind tarsi, hind tibial spinulation, forewing appendix and venation. The male genitalia was the key and the most important taxonomic feature for species identification based on the variation in distinguished features of pygofer, valve, subgenital plate, style, connective and aedeagus. Checklist for the leafhopper species of Cicadellidae collected from all the four agro-climatic zones of Himachal Pradesh was prepared along with the lists of economically important leafhopper species that are well known pests of crops as well as vectors of serious plant pathogenic diseases. The photographs of each recorded specimen were provided along with the diagnostic keys which were prepared for their identification. The distribution of the species might be very useful in future to sketch good pest management practices and policies designed specifically for the particular region. The information generated through this study will be useful for further revision and taxonomical updating of higher level classification of leafhopper fauna of the hill statefor their identification.

    STUDIES ON GEOGRAPHICAL VARIATIONS AMONG FRUIT FLIES, Bactrocera spp. (DIPTERA: TEPHRITIDAE) IN DIFFERENT REGIONS OF NORTH INDIA
    (UHF,NAUNI,SOLAN, 2017) THAKUR, PRIYANKA; SHARMA, KRISHAN CHANDER
    ABSTRACT The present investigation on “Studies on geographical variations among fruit flies, Bactrocera spp. (Diptera: Tephritidae) in different regions of North India” was carried out during 2014-2015 in the Vegetable Entomology laboratory of the Department of Entomology, Dr. Y S Parmar University of Horticulture and Forestry, Nauni, HP. Five different geographical regions of North India viz. Solan (1,502 mt amsl), Jaach (733 mt amsl), Pantnagar (344 mt amsl), Ludhiana (262 mt amsl) and Hisar (215 mt amsl) were selected to study the variations in the developmental and reproductive biology of two species of fruit fly, viz. Bactrocera cucurbitae and Bactrocera tau under laboratory conditions. The developmental period of B. cucurbitae was found to be maximum in the Hisar population (15.20 days), whereas it was minimum in the Ludhiana population (11.75 days). The total developmental period among the five populations of B. tau was the longest for the Pantnagar population (16.20 days) and shortest for the Jaach (11.60 days) population. Morphometric dimensions of B. cucurbitae revealed significant differences among populations of different geographical regions of North India at different developmental stages. Maximum body length of the adult male and female were observed in the Jaach population (9.11 and11.04mm) and the minimum in Ludhiana population (8.66 and 10.34mm), respectively. Morphometrical analysis of the B. tau reveal that in the adult male and female, the maximum length was observed in the Jaach population (9.41 and 11.78mm) and the minimum in Ludhiana population (9.02 and 11.05mm), respectively. Variations in the fertility parameters of the populations of B. cucurbitae and B. tau collected from five different regions of North India were observed. The highest value of the true intrinsic rate of increase (rm) was observed in the Jaach population (0.148) followed by Solan (0.132), Pantnagar (0.130), Hisar (0.117) and Ludhiana (0.090) populations thus indicating that B. cucurbitae from Jaach region is more generative as compared to the population from other regions. In B. tau, the value of the true intrinsic rate of increase (rm) was also found to be highest for Jaach population (0.153) followed by Hisar (0.140), Solan (0.138), Ludhiana (1.120) and Pantnagar (0.116) thus indicating that the population of Jaach region was the most prolific. Three species of fruit flies, B. cucurbitae, B. tau and B.zonata (19 isolates) were molecularly characterized with mtCOI gene and were submitted to GenBank, NCBI (USA) with accession number KX380855- KX380873. The genetic diversity was too low amongst these populations, considering the geographic scale of the sampling. Seven tomato varieties were screened for the infestation of fruit fly. Avtar, Rakshita, Naveen 2000+, US 2853 and Heem Sohna varieties were found to be moderately susceptible to fruit fly infestation.

    EVALUATION OF PLANT PRODUCTS AND OTHER NOVEL METHODS FOR THE MANAGEMENT OF FRUIT FLY Bactrocera spp. INFESTING CUCUMBER
    (2012) THAKUR, PRIYANKA; GUPTA, DIVENDER
    ABSTRACT The present studies on “Evaluation of plant products and other novel methods for the management of fruit fly, Bactrocera spp. infesting cucumber” were conducted in laboratory as well as field conditions. In laboratory studies, different concentration of azadirachtin (Econeem 10,000 ppm) (0.005, 0.01 and 0.015%), neem oil (1, 2 and 3%), Daman 1% WP (B. bassiana) (0.1, 0.5 and 1%), pongamia oil (1, 2 and 3%) and clay (6, 8 and 10%) were evaluated for oviposition deterrence. Azadirachtin (0.015%) followed by neem oil (3%), Daman (1%) and clay (10%) proved effective with 89.09, 80.24, 83.40 and 89.29 per cent oviposition deterrence over control, respectively. Cucumber slices when dipped in pongamia oil (1, 2 and 3%) caused degradation in the tissues due to which further studies could not be carried out under laboratory conditions. Egg hatchability in different treatments was worked out. Azadirachtin (0.015%), neem oil (3%), Daman (1%) and clay (10%) resulted in minimum 32.75, 59.47, 39.79 and 61.00 per cent egg hatch with 2.5, 1.5, 2.2 and 1.5 times decrease over control. Best treatments obtained in the laboratory studies were also evaluated in the field for their efficacy to check fruit fly infestation. Azadirachtin @ 0.01 per cent and Daman @ 1 per cent proved equally effective in checking fruit fly infestation with 31.20 and 37.74 per cent followed by neem oil (3%) where 40.78 per cent fruits were found infested. Pongamia oil (2 and 3%) evaluated in the field resulted in 46.12 and 48.12 per cent fruit infestation, respectively. In clay treatments, 44.98 and 43.03 per cent fruit infestation was recorded at 8 and 10 per cent concentration, respectively. All the treatments were superior over control (65.19%). The highest yield (3.1 kg/plot) was obtained in 0.01 per cent azadirachtin treated plots followed by neem oil (2.7 kg/plot) applied @ 3 per cent and Daman 1% WP (2.5 kg/plot) @ 1 per cent concentration. In pongamia oil and clay treatments the yield ranged between 2.2 to 2.6 kg/plot in comparison to 1.8 kg/plot in control. The yields/plot were inversely proportional to fruit infestation. In field evaluation, in all the treatments no phytotoxicity symptoms were observed. Based on these studies, azadirachtin (Econeem 10,000 ppm) and Daman can be included in the module for integrated pest management against fruit flies. Clay needs to be further evaluated by using commercial formulation (Surround 50 WP) which has better adherence to surface and hence may prove better.

    EVALUATION OF SOME TOMATO GENOTYPES FOR THEIR REACTION AGAINST FRUIT BORER Helicoverpa armigera Hubner (Lepidoptera: Noctuidae) IN MID HILLS OF HIMACHAL PRADESH
    (2015) THAKUR, PRIYANKA; RANA, R.S.
    ABSTRACT Eight tomato varieties viz. Palam Pink, Solan Vajar, Solan Lalima, Naveen 2000+, Yash, Rakshita, Red Gold and Heem Sohna were evaluated for their reaction to the tomato fruit borer, Helicoverpa armigera (Hubner). Maximum infestation of fruit borer was recorded in the month of May. Egg and larval count of H. armigera was made on these varieties. The per cent fruit infestation in different tomato varieties was evaluated on the basis of number of damaged fruits and this was correlated with various parameters like fruit length, fruit diameter, fruit shape, fruit pericarp thickness, fruit weight, fruit yield, plant height, stem diameter, leaf area, number of leaf hairs, titrable acidity, reducing sugars, total sugars, total phenols, leaf macro and micro nutrients (nitrogen, phosphorous, potassium, magnesium, iron, copper, manganese and zinc). None of the varieties were found to be immune to fruit borer attack but considerable variation of infestation in different varieties was observed. The percent fruit damage varied from 15.57 to 45.30 per cent recording the highest fruit infestation in ‘Red Gold’ which was significantly at par with ‘Heem Sohna’, ‘Yash’ and ‘Palam Pink’ while the lowest fruit infestation was observed in ‘Solan Lalima’ which was at par with ‘Solan Vajar’, ‘Naveen 2000+’ and ‘Rakshita’. Fruit diameter, leaf area, leaf hairs, nitrogen, potassium, magnesium, iron and manganese content were found to be positively correlated with per cent fruit infestation while fruit length, fruit shape index, fruit pericarp thickness, total sugars, total phenols, phosphorous and zinc content were found to be negatively correlated with the attack of the fruit borer. However on the basis of maximum yield per plant present studies conclude that Naveen 2000+ which also was categorized as less susceptible was found to be the most suitable variety.
