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 BIOECOLOGY AND LIFE FERTILITY TABLES OF TOBACCO CATERPILLAR, Spodoptera litura Fab. (Lepidoptera: Noctuidae) ON DIFFERENT HOST PLANTS
    (UHF,NAUNI, 2019-07) BOPARAI, INDERPREET K; SHARMA, K C
    ABSTRACT The present investigation on “Studies on bioecology and life fertility tables of tobacco caterpillar, Spodoptera litura (Fab.) (Lepidoptera: Noctuidae) on different host plants” was carried out during 2016-2017 in the Department of Entomology, Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan. Three different host plants (castor, capsicum and tomato) were selected to study the bioecology and life fertility tables of the tobacco caterpillar at different constant temperatures (20, 25, 30 and 35°C) under laboratory condition. The incubation period was maximum on capsicum and tomato (7 days each) at 20°C, whereas it was minimum (1 day) on castor at 35°C. The larval, pupal and total development periods were maximum (26.05, 18.71 and 51.76 days, respectively) on capsicum at 20°C and minimum (7.18, 3.84 and 12.02 days, respectively) on castor at 35°C. The male and female longevity was maximum (17.42 and 18.8 days, respectively) on castor at 20°C and minimum (5.2 and 6.2 days, respectively) on capsicum at 35°C. Fecundity was highest (1754 eggs per female) on castor at 25°C and lowest (450 eggs per female) on capsicum at 35°C. Temperature and host had a significant effect on the duration of different stages and fecundity of S.litura, whereas interaction of host and temperature had a significant effect only on larval and pupal period and longevity of male and female. Life fertility tables were also constructed on castor, capsicum and tomato at all four constant temperatures (20, 25, 30 and 35°C). The highest value of the true intrinsic rate of natural increase (rm) was observed on castor (0.4632 females per female per day) at 35°C and was lowest (0.1008 females per female per day) on capsicum at 20°C. Overall studies thus revealed that castor is the most favourable host ofS.litura.
