| 4. | So researchers have headed into nature themselves measuring the toxin in pollen from plots of gm corn estimating how much of it drifts onto plants such as milkweed and finally determining the exposure of butterfly and moth larvae to the protein
因此研究人员亲下田野，到栽种基因改造作物的玉米田里测量花粉中的毒素，估计有多少毒素会飘落到马利筋之类的植物上，最后还需确定蛾蝶幼虫的毒素接触量。 |

| 7. | The flames of fear erupted again a year later when cornell university entomologist john losey and his colleagues reported that they had fed milkweed leaves dusted with bt corn pollen to monarch butterfly larvae in the lab and that those larvae too had died . that was the straw that broke the camel ' s back says david pimentel also an entomologist at cornell
一年之后，美国康乃尔大学的昆虫学者洛西等人提出报告，他们以沾有bt玉米花粉粒的马利筋叶喂食大桦斑蝶幼虫，结果那些幼虫都死了。疑惧之火再度燃起。 “这是压垮骆驼的那根稻草。 ” |
