在充满家蝇的笼子里,科学家把一只桔子放在里面,家蝇不敢在桔子周围停留。把桔子从笼里取出,刮破表皮后又放入笼里,不到一刻钟家蝇行为反常,二小时后全部死亡。为了不使家蝇接触到刮破了的桔子,把刮破皮的桔子放在笼子外面。其结果家蝇还是死了。如果家蝇直接接触微量的桔皮油,死亡更快。 In a house full of houseflies, scientists put an orange on it and houseflies dare not stay around oranges. Remove the orange from the cage, scratch the epidermis and then into the cage, less than a quarter of an hour Housefly behavior abnormalities, all died two hours later. To keep the houseflies from scratched oranges, place the scraped oranges on the outside of the cage. The result is that the housefly is still dead. If the housefly is in direct contact with a trace amount of orange peel oil, it dies more quickly.
