spoiled food不可能在24 hour裏長出幼蟲。

問過在實驗室裏專門養果蠅（very tiny one, usually been seen during the summer in the kitchen, if the garbage not been taken good care of） 的朋友，和她們實驗室研究蒼蠅的的人討論過，spoiled food不可能在24 hour裏長出幼蟲。
如果您在蒼蠅方麵有研究，could please provide the research background or reference, that the spoiled food can grow larvae quickly, your finding will widely broaden their knowledge and promote their research.
And thank you very much for your kind attention to this matter.
