請依下文回答第 46 題至第 50 題： Pollinators, such as bees, butterflies, and birds, contribute roughly $500 billion a year to global food production. Being the primary pollinators of most wild plants and many crops, bees are particularly crucial to both ecosystem stability and agricultural productivity. However, bee populations have been on the decline worldwide over the years, which has captured the attention of scientists, governments, media, and the general public. Several anthropogenic drivers have been associated with declining bee populations, such as disturbances of their natural habitats as result of agricultural intensifications and urbanization, climate change, pesticides, and management practices. Bees’ habitat loss and fragmentation are considered a major driver of their declines. Besides, climate changes in temperature and rainfall can cause significant alterations in natural habitats, thus reducing their suitability for wild bee populations. Pesticides have received much attention for their potential effects on bees. In a recent study, the research group reviews important agrochemicals with demonstrated deleterious effects on eusocial bees. Using artificial intelligence tools, the researchers explore how pesticide exposure contributes to declines in populations of honey bees, bumble bees, and stingless bees. Still, many knowledge gaps remain. Future studies should continue to increase their focus and sophistication when tackling questions concerning the declining bee populations associated with the pesticide contamination. However, little research attention has been given to potential effects of management techniques on bee declines. Not until recently, a group of researchers has addressed the importance of improving beekeeping techniques and conservation strategies to avoid reduction of genetic diversity in both managed and wild honey bees. They conclude that artificial and natural selection are needed to maintain genetic diversity in honey bees to combat, for example, the bee susceptibility to pathogens. However, more research needs to be conducted on potential effects of management techniques on bee declines. It is important to emphasize that scientific efforts alone are not enough. Additional strategies should be encouraged, including improvements of environmental education programs, changes in public awareness about wild bees through appropriate media coverage, and improvements in dialogue between scientists, industry, stakeholders, and legislators. Only comprehensive approaches, discussed by different societal actors, will result in efficient and long-term strategies to reduce the decline of wild bee populations.
