Large-scale study 'shows neonic pesticides harm bees' 大型研究结果显示烟碱类杀虫剂对蜜蜂有害

 

文字稿

迄今为止最广泛的一项研究调查得出结论:新烟碱类杀虫剂对蜜蜂和野峰有害。科研人员发现与杀虫剂中化学成分的接触降低了蜜蜂蜂巢的越冬存活率,同时大黄蜂和独居蜂的蜂王繁殖数量也有所减少。这项调查研究覆盖了英国、德国和匈牙利境内共两千公顷的土地,目的是研究杀虫剂对自然界真正的影响。请听报道。

Much research on neonicotinoid pesticides has been carried out in labs. But this study has assessed their impact in the wider environment. The researchers found that bumblebees and solitary bees exposed to the pesticides were less likely to produce new queens. For honeybees in the UK and Hungary, hives were more likely to die off over the winter.

Professor Richard Pywel is from the Centre for Ecology and Hydrology in the UK. ‘This is important because many crops globally are insect pollinated and without pollinators, we would struggle to produce some foods.’

Some environmental campaigners say these findings should spell the end for neonicotinoids. But a manufacturer says they're convinced their product isn't bad for bees and highlighted part of the study that showed honeybees in Germany were not affected by the pesticides.
