Chaudhary Charan Singh Haryana Agricultural University popularly known as HAU, is one of Asia's biggest agricultural universities, located at Hisar in the Indian state of Haryana. It is named after India's seventh Prime Minister, Chaudhary Charan Singh. It is a leader in agricultural research in India and contributed significantly to Green Revolution and White Revolution in India in the 1960s and 70s. It has a very large campus and has several research centres throughout the state. It won the Indian Council of Agricultural Research's Award for the Best Institute in 1997. HAU was initially a campus of Punjab Agricultural University, Ludhiana. After the formation of Haryana in 1966, it became an autonomous institution on February 2, 1970 through a Presidential Ordinance, later ratified as Haryana and Punjab Agricultural Universities Act, 1970, passed by the Lok Sabha on March 29, 1970. A. L. Fletcher, the first Vice-Chancellor of the university, was instrumental in its initial growth.

ThesisItem Open Access Studies on varietal screening, biology and management of rice weevil, Sitophilus oryzae (L.) on stored wheat(CCSHAU, 2018) Rohit Kumar; Yadav, S.S.The studies on rice weevil, Sitophilus oryzae (L.) with reference to biology on wheat variety WH1105, screening of 15 different varieties of wheat and management through seed protectants were carried out at Storage Entomology Laboratory, Department of Entomology, CCS HAU, Hisar during 2017. Studies on biology of S. oryzae revealed that the eggs of this species were spherical with one end pointed and another rounded, translucent and white in colour and laid singly. The average incubation period of eggs was 5.14 days. There were four larval instars and grubs were apodous, stout, short and yellowish-white in colour with brown-coloured head and pupa was soft, exarate and white to yellowish-white in colour. The average larval and pupal period varied from 28.20 to 32.20 days and an average of 29.72 days under laboratory conditions. Adult male and female lived for 32.28 and 38.46 days, respectively. The average total life cycle of S. oryzae was observed as 34.88 days. The average fecundity was recorded as 189.90 eggs per female. The oviposition period was observed as 24.80 days. Average male and female ratio was recorded as 1:1.19 indicating little dominance of female over male population. Studies on varietal screening revealed that none of the wheat variety found free from infestation of S. oryzae. However, varieties WH283, WH711, DBW17, WH1080, and WH157 were found moderately preferred. Varieties WH-2967, WH542, WH1025 and were found less preferred. Varieties WH1105, WH1124, WH1142, and C306 were least preferred and WH147 was found to be most preferred as the number of eggs, number of adults emerged, grain damage and weight loss was maximum followed by DPW62150 and PBW343. Studies on efficacy of seed protectants revealed that all the seed protectants resulted in significant difference in their effectiveness against S. oryzae. However, neem seed kernel powder, neem oil and custard apple seed powder were found very effective in controlling rice weevils followed by mustard oil, groundnut oil, mustard oil + turmeric powder and groundnut oil + turmeric powder whereas saw dust was found least effective as seed protectant followed by turmeric powder. No adverse effect of these seed protectants was observed on the germination of wheat seed at different intervals whereas the germination was observed to be maximum in the treatment of neem seed kernel powder and neem oil.ThesisItem Open Access Population dynamics and management of helicoverpa armigera (Hubner) in tomato(CCSHAU, 2018) Khokhra, Shivani; Rolania, KrishnaField studies on the population dynamics and management of H. armigera on tomato were carried out at Research Farm, Department of Entomology, CCS Haryana Agricultural University, Hisar during Rabi, 2016- 17. Results showed that eggs of H. armigera were present in field during 9th to 21st SMW whereas larval population was available from 10th to 22nd SMW. Maximum number of eggs and larval population was recorded during 15th SMW (4.92 eggs/ plant) and 16th SMW (5.1 larvae/ plant), respectively. Fruit infestation both on number and weight basis were recorded to be maximum during 3rd picking (20th SMW). Aphid and whitefly population attained a peak during 12th (25.2 aphids/ plant) and 16th SMW (5.78 whiteflies/ three leaves), respectively. Larval population of H. armigera exhibited a significant positive correlation with maximum (r= 0.669) and minimum temperature (r= 0.452) whereas highly significant negative correlation with evening and morning relative humidity with r= -0.785, -0.850, respectively. Multiple linear regression analysis showed that evening relative humidity contributed to fluctuation of H. armigera eggs to the extent of 31 per cent. Similarly, maximum temperature, minimum temperature, morning and evening relative humidity accounted for 80 per cent variability in larval population of H. armigera.Maximum parasitization (13.8%) of H. armigera eggs, coccinellids (0.76/ plant) and syrphid fly maggot population (4.2 larvae/ plant) were recorded during 13th SMW whereas spiders attained a peak (0.92/ plant) during 12th SMW. Correlation studies revealed that egg parasitization of H. armigera showed significant positive correlation (r= 0.988) with number of H. armigera eggs present in the field and coccinellids were positively correlated with number of eggs of H. armigera, aphids and whitefly present with r value of 0.777, 0.533 and 0.689, respectively. Population of spiders showed a significant positive correlation with number of H. armigera eggs and whitefly. Syrphid fly maggots were significantly and positively correlated with aphid population (r= 0.796). Evaluation of different management modules against H. armigera revealed that minimum eggs counts (0.60 eggs/ plant) and larval population (0.43 larvae/ plant) of H. armigera was recorded in module 4 (intercropping of tomato with marigold in 2:1 with a border row of marigold, release of Trichogramma chilonis @ 50,000/ ha, application of nimbecidine 1500 ppm @ 2.5 L/ ha followed by each other) and module 5 (spray of chlorantraniliprole 18.5 SC @ 150 ml /ha and spray of indoxacarb 14.5 SC @ 450 ml /ha), respectively. Module 4 (intercropping of tomato with marigold in 2:1 with a border row of marigold, release of T. chilonis @ 50,000/ ha, application of nimbecidine 1500 ppm @ 2.5 L/ ha followed by each other) was recorded to be most economical from farmers perspective with highest B:C ratio (3.98).ThesisItem Open Access Effect of cold storage on some biological characteristics of parasitoid, Aenasius bambawalei Hayat (Hymenoptera: Encyrtidae)(CCSHAU, 2014) Rathee, Mandeep; Pala RamThe present studies on cold storage and overwintering of Aenasius bamabawalei were carried out during 2012-13 both in the laboratory as well as in the screen house of the Department of Entomology, CCS Haryana Agricultural University, Hisar to generate information on effect of cold storage of the parasitoid, A. bambawalei in different stages for different durations at different temperatures on its biological parameters and to evaluate the survival of the parasitoid during winter season. Studies on cold storage of the parasitoid were carried out by storing one-day-old Phenacoccus solenopsis mummies (i.e. in pupal stage) and freshly emerged adults at four storage temperatures i.e. 5, 10, 15 and 20°C for 1 to 8 weeks. It was found that the parasitoid A. bambawalei can be stored in pupal stage (i.e. in the mummies of P. solenopsis) for 1 week at 5°C and for 2 weeks each at 10 and 15°C, respectively, without any significant effect on the key biological parameters like emergence, longevity, fecundity and sex-ratio (F1 progeny). Emergence of the adults occurred within first week during storage at 20°C, hence, this temperature was not suitable for storing the parasitoid in pupal stage. Females took more time to emerge from the mummies stored for different durations at 5, 10 and 15°C as compared to males. The parasitoid adults of A. bambawalei can be stored only for 1 week at 10°C without any significant affect on the key biological parameters like survival, longevity, fecundity and sex-ratio (F1 progeny). The parasitoid A. bambawalei can be stored at low temperatures both in pupal and adult stages. However, it can be stored safely for longer duration in pupal stage as compared to adult stage. Emergence of parasitoid adults from overwintering mummies started from 11th standard week (first week of February), being maximum in 14th standard week (first week of March) and continued until 16th standard week (third week of March) when all the parasitoid adults had emerged. Maximum temperature ranged between 20.3 to 29.6oC and minimum between 6.6 to 12.5°C during the period of adult emergence. Honey fed parasitoid adults i.e. males survived for 52-84 days (69.33 days) and females survived for 69-103 days (83.40 days) during winter season in absence of host, when exposed on 5th December. The results of the present studies may be helpful in mass rearing and conservation of the parasitoid.ThesisItem Open Access Studies on morphological basis of resistance and management of brinjal shoot and fruit borer Leucinodes orbonalis (Guenee) in brinjal(CCSHAU, 2018) Vinayaka, K. S.; Balbir SinghThe studies on brinjal genotype screening for relative resistance based on morphological parameters among various brinjal genotypes, biology of Leucinodes orbonalis and chemical control of Leucinodes orbonalis Guenee were conducted at CCSHAU, Regional Research Station, Bawal during 2017. Genotype screening based on morphological parameters revealed that, genotypes 33-3, Arka Keshav, Arka Anand were found highly resistant to brinjal shoot and fruit borer owing to presence of morphological characters which confers resistance to L.orbonalis like long fruits (28.30 cm), less diameter of fruits (8.20 cm), narrow pericarp (0.29 cm), short pedicel (3.03 cm), fruit shape (long), greater number of seeds, high hair density (221.86/cm2) and spines. While these factors were found to vary in remaining genotypes and were found susceptible to L.orbonalis.Studies on biology of L.orbonalis revealed that the eggs of this species were creamy white, laid singly. The average incubation period of eggs varied from 3.74 and 4.00 days during 1st and 2nd generations, respectively. There were five larval instars and the average larval duration varied from 11.50 to 12.85 days during 1st and 2nd generations, respectively. The pupa was dark brown in colour, obtect and the average pupal period varied from 7.61 to 7.96 days during 1st and 2nd generations, respectively. The female abdomen was swollen, whereas, in the males, abdomen was cylindrical and thinner. Adult moths lived for 4.56 to 4.94 days during 1st and 2nd generations, respectively. The total life cycle of L.orbonalis ranged from 27.74 to 29.78 days during 1st and 2nd generations, respectively. The maximum eggs were laid during September i.e., 80 eggs followed by 70.80 eggs during October 2017. The maximum oviposition period was reported during September 2017 (2.57 days) followed by October (1.99 days). There was a little dominance of female moth population. Male and female ratio ranged from 1:1.6 to 1:1.80 during September and October, respectively with an average ratio of 1:1.70. Studies on chemical control of Leucinodes orbonalis revealed that, treatments of Emamectin benzoate 5% SG and Chlorantraniliprole 18.5% SC were found most effective. The insecticides viz., Azadirachtin 5% EC and Bacillus thuringiensis 5% WP were found least effective against shoot and fruit borer. The remaining treatments viz., Spinosad 45% SC, Lambda cyhalothrin 5% EC, Pyriproxyfen 5% EC + Fenpropathrin 15% EC were found moderately effective.
