蜜蜂驱赶野生传粉昆虫，竞争花蜜花粉资源

英国安格利亚鲁斯金大学的研究发现，蜜蜂通过主动攻击和驱赶野生传粉昆虫的方式竞争花蜜和花粉资源。1研究团队在剑桥郡进行了为期两年的观察，记录了300次互动，结果显示蜜蜂在大多数竞争中获胜。1其中，蜜蜂在绣线菊上被主动避开的比例达到28.4%，在常春藤上为35.6%，约20%的蜜蜂竞争获胜涉及直接驱赶行为。1

这一竞争态势对野生传粉昆虫构成了双重压力。1领导该研究的维多利亚·巴克尔表示："这很重要，因为这意味着野生传粉昆虫面临来自蜜蜂两种竞争类型的双重挑战。"1随着英国养蜂产业的扩张，这一问题愈加突出——英国注册养蜂人数已从2010年的19,000人增至2025年的47,000人，可能对包括大黄蜂、独居蜂和食蚜蝇等野生传粉昆虫的种群构成威胁。1

Researchers from Anglia Ruskin University have found that honeybees engage in active attacks and displacement tactics to compete with wild pollinators for nectar and pollen resources 1. Over a two-year observation period in Cambridgeshire, scientists documented 300 interactions between honeybees and wild pollinating insects, discovering that honeybees won the majority of these competitive encounters 1. The study recorded that wild pollinators actively avoided honeybees on approximately 28.4% of spiraea flowers and 35.6% of ivy plants, while about 20% of honeybee victories involved direct chasing behavior 1.

The research underscores mounting pressure on wild pollinator populations as beekeeping expands in the United Kingdom 1. The number of registered beekeepers has grown from 19,000 in 2010 to 47,000 in 2025, intensifying competition for floral resources 1. According to Victoria Buckler, who led the study, "This matters because it means wild pollinators face a double challenge from two types of competition by honeybees" 1. The findings suggest that wild pollinators confront both indirect competition for limited food sources and direct physical displacement, which may threaten their populations as beekeeping activity continues to rise 1.
