Bumblebees (Bombus spp.) are pivotal to sustaining biodiversity and enhancing agricultural productivity, thanks to their unique pollination mechanisms, including “buzz pollination”. Their ability to operate under adverse conditions—low temperatures and dim light—makes them essential for crops like tomatoes, peppers, and blueberries. This study synthesizes the ecological and behavioral traits of bumblebees, such as floral fidelity and vibration pollination, and explores their indispensable role in agricultural systems, particularly in greenhouse and open-field farming. By employing a bibliometric analysis, this review identifies critical research trends and emerging frontiers in bumblebee pollination, including their integration with precision agriculture technologies like remote sensing and artificial intelligence. Notably, there is increasing research on the impacts of climate change on bumblebee behavior and distribution, with studies focusing on how environmental stressors influence pollination efficiency. Additionally, the potential of using bumblebees in agroecological approaches and their role in enhancing crop resilience in changing climates are gaining traction. Moreover, it highlights the challenges posed by habitat loss, pesticide exposure, and climate change, emphasizing the urgency of conservation efforts. This study proposes interdisciplinary strategies for optimizing bumblebee pollination services, aiming to support sustainable agriculture and strengthen ecosystem resilience. The findings provide theoretical and practical insights for leveraging bumblebee pollination to achieve global food security and ecosystem stability.

Cucumber, Cucumis sativus is one of the most cultivated vegetables in the world, which is mostly consumed raw in China. The complete chloroplast genome of C. sativus was assembled and annotated in this study. Its size was 155,525 bp, containing a large single-copy region of 86,878 bp, a small single-copy region of 18,269 bp and a pair of IR regions of 25,189 bp. Whole chloroplast genome of C. sativus contains 131 genes, including 77 protein-coding genes (PCGs), 46 transfer RNA genes (tRNAs), and 8 ribosome RNA genes (rRNAs). The overall nucleotide composition is: A of 31.1%, T of 31.9%, C of 18.8% and G of 18.2%, with a total GC content of the chloroplast genome 37.0% and AT of 63.0%. Genetic and phylogenetic analysis based on 10 plants species confirmed the position of C. sativus closely related to Cucurbitaceae species of Cucumis hystrix.

Compared with the traditional teaching methods, modern new media including the instructional and social media represent the new direction for the mode of education and teaching quietly, which contributes to the effectiveness of teaching increasingly. Interactive teaching mode at biological teaching of college is useful at least three ways: closely linked to the teaching import, experimental demonstration and information supplement. A survey about the interactive teaching mode under the new media technology has been carried out in the first half of 2015. The second grade undergraduate major in biology of Changchun Normal University are involved in our questionnaire and interview. Most of the students (77.95 percent) would like that the interactive teaching mode is introduced to their biology class.

It shows that college students as a representative of the new media user has become an important part of Internet culture. The advantages of new media applications in the field of higher education are: achieve the mobile learning, change the interaction form between college teachers and students, and improve the college teaching mode. Although the college educators expect more of the new media could be used in learning, 32.3% of the percentage is inevitably cause a feeling of loss to some extent. College teachers obliged to carefully think about new media applications in higher education in order to broaden the horizons of college students learning, so that the new media technology could give college students more positive impact.

Flipped Classroom teaching model re-plans the learning time, reversing the process of knowledge transfer and knowledge internalization, creating a new communication mechanism conducive to the interaction between teachers and students, students and students, which has created a new possibility for the reform of classroom teaching in universities. The research about how to apply the flipped classroom teaching model for educational technology major carried out for four courses in fall semester of 2016. Nearly 100 students in three grades are involved in the questionnaire, formal and informal interview. Most of the students,84.95%,believe that the flipped classroom teaching model could facilitate the active learning and the student-centered teaching. The present study confirmed that the model benefits from screening appropriate teaching content, rational grouping, and the instructional design.
