<p class="ql-block">蜜蜂为三分之一的人类食物授粉,在保护地球生态系统中发挥着重要的作用。由于人类的影响,目前物种灭绝的速度比正常水平高出了100至1000倍。全球近35%的无脊椎动物授粉媒介,尤其是蜜蜂和蝴蝶面临灭绝。为了提高人们对于授粉媒介重要性的认识,了解授粉媒介所面临的威胁及其对可持续发展的贡献,联合国将5月20日定为世界蜜蜂日。5月20日恰逢安东•扬沙 (Anton Janša) 的生日。安东•扬沙于18世纪在他的家乡斯洛文尼亚率先采用了现代养蜂技术,并称赞蜜蜂“辛勤劳作,甘于寂寞”。</p> <p class="ql-block">Western honey bee is the most common species of honey bee in the world </p> <p class="ql-block">Western honey bee</p> <p class="ql-block">Western honey bee</p> <p class="ql-block">Western honey bee</p> <p class="ql-block">American bumble bee (Left) and </p><p class="ql-block">Common eastern bumble bee (right)</p> <p class="ql-block">American bumble bee </p> <p class="ql-block">American bumble bee </p> <p class="ql-block">American bumble bee </p> <p class="ql-block">Golden northern bumble bee</p> <p class="ql-block">Golden northern bumble bee</p> <p class="ql-block">Eastern carpenter bee</p> <p class="ql-block">Common eastern bumble bee</p> <p class="ql-block">Common eastern bumble bee</p> <p class="ql-block">California carpenter bee </p> <p class="ql-block">Two-spotted bumble bee</p> <p class="ql-block">Yellow-faced bumble bee</p>
