蟑螂是令人讨厌的害虫。它们污染食物,危害人体健康。但偏偏蟑螂又是一种十分灵活的昆虫,用蝇拍都很难打着它。我们知道,苍蝇有着敏锐的复眼与灵敏的纤毛,所以很难打到它,但蟑螂靠什么感知外敌呢? 我们不妨找一只瓶子,里面涂上油,放入糖或其它蟑螂爱吃的食物。再把一根布条的一头系在瓶口,一头搭在地面,就能引诱其掉入而捉到蟑螂。 Apes are annoying pests. They pollute food and endanger human health. However, it is a very flexible insect, and it is very difficult to hit it with a fly. We know that flies have a sharp compound eye and sensitive cilia, so it is difficult to reach it, but what do you perceive to be a foreign enemy? We might as well find a bottle containing oil and put it in sugar or other favorite foods. . Then tie one end of a piece of cloth to the bottle and one to the ground to lure it in and catch it.
