我们都知道人体内会长寄生虫,像蛔虫、钩虫、血吸虫等,所以有人隔一段时间后要吃些驱虫药,以保持身体的健康。其实,你知道吗?只要有生物的地方,就会有寄生物,自然世界有多大,寄生世界就有多大,真的是异乎寻常,令人叹为观止。寄生物弱小而不起眼,比如苍蝇的幼虫,虽然小得像个小芝麻粒一般,样子毫无凶煞貌,也没有利牙利爪,看上去温文尔雅,大气不出。可是就这貌似值得同情的软弱小生物,它们却能紧紧呆在蜜蜂幼虫身上,用亲吻的柔和方式去吸吮寄主体内肉汁,一直吸到蜜蜂幼虫死去为止,手段真的是恶毒之极。动物的寄生世界是这样,植物的寄生世界同样如此。植物中有种叫女巫草,格外的神通,它是专靠吸取玉米、甘蔗和高梁等作物的营养为生 We all know that the president of the human body has parasites, such as tapeworms, hookworms, and schistosomiasis. Therefore, some people need to eat some insect repellents after a certain period of time to maintain their health. In fact, do you know that as long as there are living creatures, there will be parasites, how big is the natural world, and how large is the parasitic world? It is truly extraordinary and amazing. Parasites are weak and inconsequential. For example, the larvae of flies, although small enough to resemble a small sesame seed, have no vicious appearance and no razor-sharp claws. They look gentle and incapable of the atmosphere. But for this seemingly worthy sympathetic weak creature, they can stay tightly on the bee larvae, sucking the gravy inside the body with a gentle kiss, and sucking until the bee larvae die. The means are really vicious. The parasitic world of animals is such that the same is true of the parasitic world of plants. Among the plants, there is a species called witch grass, which is a special supernatural power. It is based on the nutrition of crops such as corn, sugar cane and sorghum.
