宋代的杨鸾为蚊蝇所苦,曾作诗纪实:“白日苍蝇满饭盘,夜来蚊子又成团。每到更深人静后,定来头上咬杨鸾。”时间过去了近1000年,苍蝇和蚊子一路繁衍下来,肆虐如故,让现代的杨鸾们叫苦不迭。说来真是可叹,人类科学技术的发展日新月异,一颗原子弹便可要了上百万人的性命,竟于蚊蝇二物,仍是“华佗无奈小虫何”。发明苍蝇拍、苍蝇板,发明回形蚊香、电动驱蚊器,国外甚至有建立驱蚊电台的,都只能收到一时之效,而达不到一劳永逸,长治久安。这两种仿佛魔鬼派出的使者,每年总是如期前来。
Yang Song of the Song Dynasty for the mosquitoes bitter, had a poem: “day full of flies dishes, mosquitoes into the group at night .Every time deeper, will come to bite Yang 鸾.” “The time has passed In 1000, flies and mosquitoes all the way to multiply, wreaking havoc, let the modern Yang Kui are complacent. To say it really lamentable, the rapid development of human science and technology, an atomic bomb can have the lives of millions of people, even in mosquitoes two things, is still ”Huafa helpless insect". The invention of fly swatter, fly board, invented mosquito repellent incense, electric mosquito repellent, foreign and even the establishment of repellent radio, can only receive a temporary effect, but less than once and for all, long-term stability. These two messengers, as if sent by the devil, always arrive on schedule every year.
