    Persistence and dissipation of ready premix formulation (Novaluron + Indoxacarb) in/on tomato (Lycopersicon esculentum Mill.) and its leaching in soil
    (CCSHAU, 2017) Anita; Madan, V.K.
    A field experiment was conducted to study the persistence behaviour in tomato fruits and soil underneath and effect of processing on the reduction of residues of ready pre-mix formulation (Novaluron 5.25% + Indoxacarb 4.5% SC) during 2014-15. A laboratory experiment was perfomed for assessing the leaching potential of ready pre-mix formulation of novaluron and indoxacarb at two doses in soil (sandy loam) and leachate fractions. The field experiment was laid out at Research Farm of Department of Entomology, CCS HAU, Hisar using randomized block design (RBD) on tomato crop (variety HS-86). Single dose (T1) consisted of 825 g ha-1 (equivalent to 43.31 g.a.i.ha-1 novaluron + 37.13 g.a.i.ha-1 indoxacarb) and double dose (T2) consisted of 1650 g ha-1 (equivalent to 86.62 g.a.i.ha-1 novaluron + 74.26 g.a.i.ha-1 indoxacarb) of ready pre-mix formulation. Samples of tomato fruits and soil were collected periodically on 0 (1h), 1, 3, 5, 7, 10 and 15 days after applications. Residues were estimated by gas chromatography (GC) equipped with capillary column and electron capture detector (ECD). Per cent recoveries at the fortification levels of 0.01, 0.10 and 0.25 mg kg-1 in tomato fruits and at 0.01 and 0.05 mg kg-1 in soil were in the range of 82-94 per cent depicting validity of methods used for present studies. Limit of detection was 0.005 mg kg-1. Dissipation in tomato fruits followed first order kinetics with half life period from 1.40 - 2.48 days at both the doses of novaluron as well as indoxacarb. Various household processing were found to be effective in reducing the residues of ready pre-mix formulation of novaluron and indoxacarb in tomato fruits. Residues decreased substantially during household processing among which peeling was found most effective which resulted 80-89 % reduction. For sandy loam soil under tomato crop, half-life period was found to be in the range of 0.63 to 2.17 days at single and double doses, respectively, for both novaluron as well as indoxacarb following first order kinetics. In leaching experiment carried out under laboratory conditions, 55 - 60% retention of novaluron and 70 - 75% retention of indoxacarb were observed up to 10 cm soil in both the doses, showing their very less mobility in soil. Residues were not detected after 40 cm depth of soil in both the doses. Since, residues of novaluron and indoxacarb were not detected in any of the leachate fractions of soil, hence, these may be safe for soil and ground water contamination.

    Isolation and identification of associated proteins/allergens in mite, Tyrophagus putrescentiae (Schrank) and its management
    (CCSHAU, 2016) Anita; Gulati, Rachna
    Investigations were carried out to assess the incidence of Tyrophagus putrescentiae in granaries, flour mills and domestic storage. In granaries, first peak in the month of October (12.33 mites/50g residual dust) and in flour mills and domestic storage, it was recorded in the month of November (30.06, 18.06 mites/50g wheat flour). At all the sites, second peak was recorded in the month of May (23.40, 33.26 and25.13 mites/50 g sample, respectively). Significantly more number of mites (19.00, 17.00 mites/50g grains) were recorded in open type storage (wheat grains stored on the floor of a room) than in metallic bins. Mite incidence showed significant positive correlation with maximum temperature, sunshine hours and negative correlation with evening relative humidity in granaries, flour mills and domestic storage structures. In the latter two survey sites, significant negative correlation between mite incidence and morning relative humidity was also observed. Significantly higher number of mites were recorded in flour mills (24.83 mites/ 50g sample) followed by domestic storage structures (15.84 mites/50g sample) and granaries (9.56 mites/50g sample). Maximum number of mites (64.72 mites/50g sample) were recorded during summer season (April- June), followed by winter (60.26 mites/50g sample; October- January), rainy (44.93 mites/50g sample; July- September) and spring (30.98 mites/50g sample; February-March) season. Seven unknown protein of 90 kDa, 87 kDa, 68 kDa, 50 kDa, 36 kDa, 26 kDa and 16 kDa molecular weight were isolated from T. putrescentiae body. wheat flour infested with T. putrescentiae showed a significant higher count of protein, fat acidity, free fatty acids, peroxide value whereas total antioxidant activity decreased in infested flour. The pathogenicity of Beauveria bassiana against T. putrescentiae was evaluated. Under in vitro 20 to 80.5 and 17 to 74.5 percent mortality of T. putrescentiae was recorded in Direct Spray and Treated Observation arena Bioassay, respectively with 1 × 105 to 1 × 1012 conidia ml-1 concentrations of B. bassiana. LC50 values of B. bassiana were in the range of 1.83×109 to 4.45× 1011 conidia ml-1 and LT50 values varied from 1.05 to 48.17 h for eggs, larvae, nymphs and adults in both the bioassay methods. Direct Spray Bioassay was more effective as compared to Treated Food Bioassay.

    Impact of Intervention Programme on Thinking Skills of Institutionalized Adolescents
    (CCSHAU, 2015) Anita; Duhan, Krishna
    The present investigation was conducted purposively in Haryana and Delhi state. Two hundred adolescents, i.e., 100 boys and 100 girls in the age group of 13 to 19 years were selected randomly from the selected institute of Faridabad (Haryana) and institute of Bawana (Delhi). The thinking skills of adolescents were assessed by Life Skills Assessment Scale (LSAS) developed by Nair et.al (2010). Beck depression inventory (BDI-II) developed by Beck et.al (1966) was used to estimating depression among adolescents. Test anxiety scale (TAS) developed by Sharma (1978) was used to measure the anxiety level of adolescents. A life stress scale developed by Aggarwal and Naidu (1986) was used to study the level of stress among adolescents. After assessing the existing thinking skills, adolescents were further assigned to experimental group (50) and control group (50) from each Institute. Intervention package on thinking skills was developed and imparted to the experimental group adolescents. Results of the study highlighted that institutionalized adolescents had average level of thinking skills in all four dimensions i.e. problem solving, creative thinking, decision making and critical thinking skills. Age, gender and relationship with peers were found significantly associated with thinking skills among adolescents. Majority of adolescents had moderate level of depression, anxiety and stress and exhibited negative and significant correlation with all dimensions of thinking skills. Intervention program enhanced the thinking skills of institutionalized adolescents to a great extent. A significant improvement was found in the mean scores of adolescents after imparting intervention program. The study demands to get aware the parents, teachers and others who are concerned with adolescents to explore and enhance their thinking skills.

    (CCSHAU, 2006) Anita; Dahiya, Manju
    The process of change is increasingly becoming pervasive. Training is an indispensable instrument for human resource development. Training aims at helping individuals enhance their potential by way of increased knowledge, changed attitudes and improved skills thereby enabling them to perform in a better and professional manner. To assess the impact of institutionalized Home Science trainings organized by Institute of Agricultural Technology Training and Education (IATTE), CCS Haryana Agricultural University, Hisar the present study was conducted. Since inception in 1975 to 2005 IATTE had been conducted 365 trainings in the field of Home Science comprising of 332 subject specific and 33 miscellaneous trainings benefiting 10,634 participants. Five trainings, are each from the five disciplines of Home Science which had maximum respondents during last five years were selected. These were training on baking, tie and dye and embroidery, soap and detergent making, table setting, napkin folding, flower arrangement and flower making and soft toys making. A sample of 100 women respondents who had attended these trainings during last five years were selected randomly. The data was collected personally through interview technique. Socio-personal, economic, training and communication variables were taken as independent variables, whereas training impact was taken as dependent variable, which included knowledge, skill, satisfaction and leadership. Profile of respondents selected indicated that majority attending trainings at IATTE were young aged, resided in city, unmarried, graduate, belong to high caste, had nuclear medium size family, not member of any organization, were unemployed, medium family income, have high mass media exposure of TV and information of training was received through press release. It was noted that among the motivational reasons for attending training major one was to learn a new skill. Respondents gained highest knowledge (WMS 0.86) for soft toys making followed by (WMS 0.78) for tie and dye and embroidery, WMS 0.75 for soap and detergent making, (WMS 0.73) for table setting, napkin folding, flower arrangement and flower making and baking also. Highest skill WMS was 1.54 in tie and dye and embroidery followed by 1.47 in soap and detergent making, 1.42 in table setting, napkin folding, flower arrangement, flower making, 1.35 in baking and 1.30 in soft toy making. It was observed that highest satisfaction WMS was 0.98 in soft toys making training, followed by 0.95 in tie and dye and embroidery and also in table setting, napkin folding, flower making, 0.88 in soap and detergent making, 0.87 in baking. Highest leadership WMS was 0.93 in baking , followed by 0.85 in tie and dye and embroidery, 0.78 in soap and detergent making and soft toys making, 0.73 in table setting, napkin folding, flower arrangement, flower making. Marital status and education were found to be significantly associated with knowledge
