<此处为图片> You might think that honey bees are important because they make honey — but that is not the only reason they matter so much. The most important thing they do is pollinate plants, from food crops to trees, helping them to reproduce. ______ Colony Collapse Disorder has been happening at such a rate that it has been dubbed “bee aids”. In the winter of 2017-2018 nearly 30% of bee colonies in America collapsed. They were opened in the spring only to discover that only the queen bees and the eggs remained. ______ This is strange because bees do not normally abandon a functioning hive at all, and, if they do abandon a hive, the honey within is usually eaten by other bugs, such as beetles. However, in cases of CCD such pests leave the hive and its honey alone and intact. ______ Some suggest that it is a microbe called the Acute Paralysis Virus that is wiping out bee colonies. Others think it may be due to a parasite called the Varroa mite which feeds on blood. Another culprit could be a fungus which lives in the gut and is called Nosema Ceranae. Even modern technology has been claimed for causing CCD. ______ However, the number of bee colonies in America has fallen from nearly 6 million 60 years ago, to approximately 2.5 million today. CCD has not reached Britain yet but the Varroa mite has. By the spring of 2017 a quarter of all bee colonies had died. ______ People are keen to learn aspects of beekeeping ranging from how a hive is actually structured to how bees communicate with each other. This increased popularity is partly due to heightened concern about the environment and a wish to be self sufficient. Beginner's courses now run throughout the year. For anyone thinking about taking up apiary (蜂房) seriously there are twelve-week courses available country-wide which cover both theory and practical skills. (缺图)
