美国圣母大学生物学家杜曼博士发现昆虫以二种方式来渡过严寒。许多昆虫是依靠它们体内的类似血液的浆液中含有的防冻物质来防止类血液结冰。另一些昆虫则具有承受冷冻的能力,它们在冬季龟缩不动,而大地回暖时,体内自动“解冻”,开始活动。 Dr Doman, a biologist at the University of Notre Dame, found that insects were able to cross the cold in two ways. Many insects rely on anti-freeze substances contained in their blood-like serums to prevent blood from freezing. Other insects have the ability to withstand freezing, they are frozen in winter, and the earth warms up, the body automatically “thawed” to start activities.
