在教学过程中,常需将实验用蛙保存一段时间。蛙不吃死昆虫,从市场买回的蛙往往已饿了好多天,为了保存这些蛙,可采用下面的方法:晚上,将一盛有水的盆放在室外窗台,盆内斜放装蛙的铁笼,让笼底一部分浸入水中。在笼的旁边放一盏8瓦的小台灯(灯的瓦数不宜过大,不宜用白炽灯,以免温度过高而影响蛙的活动)。灯亮后,夜间活动的昆虫就会“光临”铁笼供蛙捕食。到早上再将蛙连盆移入实验室 In the teaching process, often need to save the frog with experimental period of time. Frog does not eat dead insects, frogs bought from the market often have been hungry for many days, in order to save these frogs, the following methods can be used: In the evening, a basin filled with water on the outdoor windowsill, Cage, so that part of the cage immersed in water. Next to the cage put a small 8-watt desk lamp (lamp wattage should not be too large, incandescent lamps should not be used to avoid the temperature is too high and affect the activities of the frog). When the lights are on, insects moving at night will “come” to the cages for frog prey. In the morning, move the frogs into the lab again
