The study was conducted on bio-ecology and management of mango mealybug Drosicha mangiferae (Green) in mango orchards of Punjab Pakistan from 2004 to 2008 in District Multan, Muzzaffar Garh, Bahawalpur and Rahim yar Khan. It was concluded from the growers’ survey that among various insect pest of mango, mango mealybug was found to be the major pest followed by hoppers, fruit fly, scales, mango leaf galls Amaraemyia spp. and midges. The farmers also reported that mango mealybug caused 25-100% loss. Further the respondents indicated that ‘Chaunsa’ cultivar was the most susceptible to mango mealybug followed by ‘Fajri’, ‘Langra’ and ‘Black Chaunsa, whereas ‘Dusehri’ was resistant. Irrigation was the major source of flare up of the pest as viewed by the majority of the respondents. The practices like hoeing, ploughing, irrigation, removal of weeds, grease bands and insecticides were adapted by the respondents with variable results. The satisfaction level for the control of mango mealybug was unsatisfactory. South, East, West directions of trees showed maximum population of mango mealybug on leaves and inflorescence, whereas North direction of the plant showed minimum population. The maximum peak population of mango mealybug was observed to be 26.63 per 30-cm branch at maximum temperature of 24.64°C, minimum temperature of 10.36°C and RH 78.86%. Among twelve cultivars under study, the ‘Chaunsa’ cultivar of mango showed maximum population of mango mealybug in both the study years (104.90 and 69.83 during 2005-2006 and during 2006-2007, respectively as well as on an average of both study years (87.38), whereas ‘Tukhmi’ cultivar was found comparatively resistant with minimum population of mango mealybug i.e. 14.20, 15.86 and 18.27. On an average of both the study years, the following ranking positions towards susceptibility of mango cultivars were as under. ‘Chaunsa’ > ‘Black Chaunsa’ > ‘Malda’ > ‘Fajri’ > ‘Ratul- 12’ > ‘Langra’ > ‘Sensation’ > ‘Sindhri’ > ‘Dusehri’ > ‘Sufaid Chaunsa’ > ‘Anwar Ratul’ and >‘Tukhmi’. All the chemical plant factors on leaves and inflorescence differed significantly among various cultivars of mango. Maximum carbohydrates contents was observed in the cultivar ‘Chaunsa’ (susceptible to the pest), whereas minimum carbohydrates contents were observed in the cultivar ‘Tukhmi’ resistant to the pest. All the other factors did not show any specific sequence with the population of the pest in all the cultivars. The maximum decrease in number of fruits was recorded 11 percent on cultivar ‘Anwar Ratul’, whereas ‘Langra’ cultivar showed minimum decrease in number of fruits i.e., 3 percent over untreated trees (no control practices were applied with these trees to control mango mealybug at initial stage of the experiment). At final stage of the experiment the maximum decrease in fruits was 81 percent on cultivar ‘Chaunsa’ and minimum on cultivar ‘Tukhmi’ i.e., 22 percent. Maximum population recorded on ‘Chaunsa’ cultivar was 18/inflorescence and minimum on ‘Anwar Ratul’ was 10/inflorescence. A combination of mounds on the plastic sheet, Haider’s band and application of acetamiprid were found to be the most effective treatment resulted in 98% reduction of first instars of mango mealybug. It is further stated that the Haider’s band was the most effective and cheaper which was a new addition in the mechanical control management of mango mealybug on mango trees. The males of mango mealybug were attracted to mercury light and no males were attracted to yellow, green, red, blue lights. Male preferred to pupate in wet places near the ‘kacha’ (mud) water which can be exposed to sunlight by hoeing. This research project demonstrates the complete management programme for the control of mango mealybug under field condition for mango growers.

Level of Readiness of the Public School Teachers in Introducing Students Learning Outcomes Based Assessment for Grade V Board Level Examination in Gilgit-Baltistan Gilgit Region

Assessment is one of the very important and essential domains of education to determine students' learning attainment. Authenticity and effectiveness of education system cannot be determined without reliable and valid assessment. There have been different types of assessments used for different levels and fields in education. In the present time, Student Learning Outcomes (SLOs) based assessment has emerged as leading and the most acceptable ways of assessing students' learning in most part of the world. This dissertation explores the readiness level of teachers in introducing SLOs-based assessment in grade V board level examination in Gilgit-Baltistan, Gilgit region, through quantitative research method. Teachers' views about SLOs-based assessment, perceptions about the successful implementation of SLOs-based assessment, various challenges that would teachers face and professional training needs of teachers, if SLOs-based assessment is being introduced in grade V board level examination discussed in various themes. A newly developed and validated survey questionnaire ISLOBA, based on five-point Likert scale was used for data collection. 1 80 male and female participants were selected through multi grade stratified sampling procedures. The validated questionnaire was distributed among the participants in district Ghizer for data collection. Further, the data were tabulated, analysed and interpreted category wise and findings were made employing descriptive statistics. The study concludes that majority of the respondents were not satisfied with the current traditional way of board examination system of class V. In contrast, large number of respondents considered SLOs-based assessment as an important way of assessing child's personal, social development as well deeper understanding, and critical thinking skills. Some teacher were feeling themselves equipped, while equally same number of teachers stated that they need professional trainings before introducing new examination system. Majority of respondents were of the view that, if SLOs-based assessment is introduced it would reduce the chances of text cramming and rote memorization among students. It was also stated that implementation of the SLOs-based assessment mainly depends very much on the school level leadership and a reform of the existing examination system. Hence, Outcome Based Assessment plays an important role in enhancing students' motivation and autonomy in their learning. Based on the findings, this paper discusses some of the suggested processes to be included in the implementation of SLOs-based assessment and the issues to be considered in the actual implementation.
