迄今為止最廣泛的一項(xiàng)研究調(diào)查得出結(jié)論：新煙堿類殺蟲劑對(duì)蜜蜂和野峰有害。科研人員發(fā)現(xiàn)與殺蟲劑中化學(xué)成分的接觸降低了蜜蜂蜂巢的越冬存活率，同時(shí)大黃蜂和獨(dú)居蜂的蜂王繁殖數(shù)量也有所減少。這項(xiàng)調(diào)查研究覆蓋了英國(guó)、德國(guó)和匈牙利境內(nèi)共兩千公頃的土地，目的是研究殺蟲劑對(duì)自然界真正的影響。請(qǐng)聽報(bào)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.
