Suspicion had fallen on a neonicotinoid first made by Bayer called imidacloprid.

怀疑的对象是拜耳公司首先生产的一种名为吡虫啉的新烟碱。

They exposed some, via contaminated pollen and sugar water, to high doses of imidacloprid, a type of neonicotinoid insecticide.

他们用受污染的花粉、糖水将一些蜂群暴露在高剂量吡虫啉-一种新烟碱杀虫剂的环境里。

And of course we put it down to the fact that imidacloprid, like all neonicotinoids, inhibits the immune system.

当然，我们将其归因于吡虫啉和所有新烟碱类药物一样，会抑制免疫系统。

Both of the groups that had been exposed to imidacloprid harboured an average of 700,000 parasite spores in each bee.

接触到吡虫啉的两组蜜蜂每只体内寄生孢子的平均数量是700000。

Instead, the results of this comparative study, which we now know were worthless, were taken as proof that imidacloprid is harmless for bees.

相反，这项比较研究的结果被当作吡虫啉对蜜蜂无害的证据，虽然我们现在知道它毫无价值。

" Imidacloprid is the first highly effective insecticide that works on the principle of almost completely blocking receptors, in a way that is virtually irreversible."

“吡虫啉是第一种高效杀虫剂，它的原理是几乎完全阻断受体，在某种程度上是不可逆转的。”

The medaka that were in the mesocosms treated with imidacloprid were all, absolutely all 100 percent of the fish, were contaminated with protozoan parasites.

在接受吡虫啉处理的中系中，所有的鱼都被原生动物寄生虫污染了。

All of the doses of imidacloprid, both high and low, that Dr Whitehorn gave her bees were sublethal—in other words, insufficient to kill the insects outright.

所有的吡虫啉无论剂量大小，Whitehorn博士都是把亚致死量用在她的蜜蜂上，换句话说，不足以立刻杀死昆虫。

The researchers note that another British study found levels of imidacloprid in rape crops that were seven times higher than the food supplied by the researchers.

研究人员指出另一个英国研究项目发现油菜作物里的吡虫啉含量要比研究人员提供的食物里的吡虫啉含量高七倍。
