Samples of sugarcane leaves and soil were collected at various time intervals and analysed by using Gas Liquid Chromatograph (GLC) and confirmed by Gas Liquid Chromatograph –Mass Spectrometry (GC-MS). The total residues of fipronil and its metabolites in sugarcane leaves after 7 days of its application @ 75 and 300 g a.i. ha-1 were found to be 0.26 and 0.66 mg kg-1, respectively.These residues could not be detected after 60 and 90 days following the application of fipronil at lower and higher dosages, respectively. The samples of sugarcane juice did not reveal the presence of fipronil residues at harvest. Maximum residues of fipronil and its metabolites in soil samples were found to be 0.025 and 0.098 mg kg-1 collected 7 days after the application of fipronil @ 75 and 300 g a.i. ha-1, respectively. These residues could not be detected after 210 and 240 days following the application of fipronil at lower and higher dosages, respectively. In laboratory experiment, the residues of total fipronil in sandy loam, loam and clay loam after 7 day of its application @ 100 mg kg-1 were found to be 74.30, 75.80 and 82.50 mg kg-1, respectively. The persistence of fipronil was found to be almost equal in all types of soil. Three soil microbes viz. Bacillus firmus, Bacillus aerophilus and Bacillus thuringiensis were isolated and identified from sugarcane fields. These were found to be very effective in degradation of fipronil.ThesisItem Restricted ABSORPTION OF B-CAROTENE FROM COMMON PUNJABI DIETS(PUNJAB AGRICULTURAL UNIVERSITY; LUDHIANA, 1992) NEERAJA RANI; HIRA, C. K.ThesisItem Open Access Abundance and breeding biology of Indian Pond Heron (Ardeola grayii) in village ponds of Punjab(Punjab Agricultural University, Ludhiana, 2018) Sukhbirpal Kaur; Kler, Tejdeep KaurThe present study was undertaken to investigate the abundance of Indian Pond Heron and other water birds species in and around the village ponds of Punjab. In addition the breeding biology including the pair formation, nesting sites, egg laying, clutch size, hatching period and hatching success of Indian Pond Heron was also studied. The study was carried out in and around village ponds of District Barnala and Ludhiana from February 2017 to January 2018. A total of 54 bird species were recorded out of 17 bird species were water dependent. Indian Pond Heron was found less abundant in Punjab. The breeding period started from March to September. It preferred indigenous trees like Peepal, Banyan, Jamun, Dhek and Kikar for nest building. Nest was more commonly at upper and outer canopy of trees. Nest was unarranged, flat made of sticks and twigs and was always recorded at heights above 6 m. Clutch size varied between 2 to 5 eggs. Clutch of three eggs was most common. Eggs of were sea green, oval and without spots. Egg length and egg width varied from 26.34 mm to 43.56 mm and 18.37 mm to 34.45 mm respectively. Egg weight varied from 9.13 gm to 15.03 gm. Egg albumen ranged from 2.94 gm to 4.55 gm; egg yolk weight ranged from 5.22 gm to 8.15 gm; egg shell weight varied from 1.00 gm to 1.32 gm. Mean egg shell thickness recorded was 0.28 ± 0.01 mm. Percentage of calcium carbonate ranged between 63.96 per cent to 86.41 per cent. Mean calcium carbonate content in egg shells of Indian Pond Heron was 0.81 ± 0.01 gm.ThesisItem Restricted ACADEMIC PERFORMANCE AND ACADEMIC ASPIRATIONS OF RURAL TENTH CLASS GIRLS(PUNJAB AGRICULTURAL UNIVERSITY; LUDHIANA, 1988) DHALIWAL, KANWALJIT KAUR; GOYAL, G.ThesisItem Open Access Acaricide resistance and its biochemical and molecular bases in two-spotted spider mite, Tetranychus urticae Koch(Punjab Agricultural University, Ludhiana, 2017) Sharma, Rakesh Kumar; Bhullar, Manmeet BrarTwo-spotted spider mite (TSSM), Tetranychus urticae Koch (Acarina: Tetranychidae), has gained importance in view of their widespread occurrence as a pest on vegetables in Punjab. Studies were conducted to monitor the magnitude of acaricide resistance in T. urticae, against different acaricides viz., propargite, spiromesifen, fenpyroximate and fenazaquin collected from different vegetable growing areas (Amritsar, Hoshiarpur, Malerkotla and Patiala) of Punjab and its mechanism through biochemical and molecular diagnosis. The development of acaricide resistance has been screened in field populations of T. urticae and compared with a laboratory reared susceptible population based on toxicity bioassay using leaf disc dip technique. Patiala population was least susceptible to fenazaquin (RR 24.65) among all tested acaricides while Amritsar population was found to be highly susceptible (RR 6.67) Among all tested acaricides, fenpyroximate (0.00205 – 0.00954 per cent) was found to be the most toxic against all the tested populations except Malerkotla population.Therefore, low to moderate levels of resistance (3.19-24.65 fold) was observed in T. urticae to tested acaricides in Punjab. Biochemical and molecular analysis were done with Fenzaquin selected resistant population that was developed in the laboratory by giving selection pressure with fenazaquin up to 15 generations. Selection with fenazaquin significantly increased the activities of monooxygenases, GST and esterases by 3.21, 1.40 and 1.13-1.27 fold, respectively when compared to susceptible population proving their role in Fenazaquin mediated resistance. Molecular analysis of resistant and susceptible population revealed no changes in genes structure of mtCOI, CYP392A11 and CYP392A12 in the resistant compared to the susceptible population. However, expression profiling of nine different genes associated (CYP392A11, CYP392A12, CYP392A16, CYP392D2, CYP392D3, CYP392D6, CYP392D7, CYP392D8 and CYP392D10p) with METI resistance showed increased mRNA transcripts in CYP392A11, CYP392A12, CYP392D2 and CYP392D10p. The increased MFO activity in the resistant population corresponds to nearly twice fold increase in the expression of CYP392A11 and CYP392A12. The moderate level of resistance observed in the selected population may be attributed to both increased enzyme activity and gene expression. The target site mutation might not have any role in low to moderate level of fenazaquin resistance in mites. Enzyme and mRNA expression has the wide potential to be used as a fast and reliable tool for early detection of resistance against METI acaricides.ThesisItem Restricted ACCEPTANCE OF SOYABEAN PREPARATIONS BY PRE SCHOOL CHILDREN AND THEIR MOTHERS AND ATTITUDE OF MOTHERS FOR ITS USE(PUNJAB AGRICULTURAL UNIVERSITY; LUDHIANA, 1972) GUPTA, NILAM; SRIVASTAVA, P.
