A proverb goes that education is the backbone of a nation. No nation can step up without educating the nation. Quality education is achieved by the better academic performance of the students. Indeed, the university is the tertiary education where the undergraduate students are enrolled to appropriate academic excellence that can be transformed to better the nation. There are a variety of positive and negative factors that affect the academic performance of undergraduate students. Here, this study endeavors to identify the success and failure factors influencing the academic performance of Rabindra University, Bangladesh. In doing so, this study is conducted based on primary data. Convenient and cluster random sampling method has been used. Two different questionnaires and opinionnaire are developed for both students and faculties as the instruments of data collection and the 4-point Likert scale of measurement is used to analyze the responses. The findings show that regular attendance, regular study, hard work, dedication & self-Confidence and Support by family members and others have a high impact on the academic performance of undergraduate students. On the other hand, insufficient effort in studying, lack of interest in the subject, the noisy and unfriendly environment in the institution influence inversely. This result will surely help the students, faculties and administration to design policies convenient for the education system of the university and the nation as a whole.

to investigate the effects of temperature, relative humidity, and rainfall on the incidence of sucking pests (thrips, aphids, and red spider mites) on roses. The results showed that the thrips population started to increase in the first week of January, gradually increasing and reaching its maximum (2.6 ± 0.2 individuals/flower) in the first week of February, and then declining. The aphid population started to increase in the second week of November, reached its peak (8.4 ± 0.6 individuals/shoot) in the last week of December, and then declining. The mite population started increasing in the second week of December, increased continuously until its peak (8.4 ± 0.4 individuals/shoot) in the first week of March, and then declining. The populations of thrips, aphids, and mites persisted until the third week of April, the third week of May, and the first week of April, respectively. Daily mean temperature and rainfall were negatively correlated with the increase in the thrips and aphid populations, while relative humidity was positively correlated with it; however, these correlations were not significant. The mite population had a significant positive correlation with temperature and a non-significant negative correlation with relative humidity and rainfall. Multiple linear regression analysis showed that weather variables together predicted 34%, 53.1%, and 41.7% of thrips, aphid, and mite abundance on rose plants.
