据国家权威部门统计资料表明:1997年我国农田鼠害面积达2500万公顷,比1996年增加50％,全国因鼠害造成粮食作物田间损失40亿公斤,棉花30万担,甘蔗10万吨以上。有关老鼠造成的灾害奇闻,已经太多,令人惊叹而沮丧。1980年,哥伦比亚竟有3000个孩子被老鼠咬伤,有些被活活咬死。同年,埃及的老鼠统一行动,占领4个省,潮水般在尼罗河三角洲东侧肆虐,为歼灭老鼠竟下了总统令。在印度,每年地里的粮食有1/5被老鼠吃掉。全世界的老鼠,每年至少要吃掉5000万吨粮食,这些粮食足足可以养活2亿人口。
According to the statistical data of the state authorities, the area of rodent pests in China reached 25 million hectares in 1997, an increase of 50% over 1996. The country lost 4 billion kilograms of grain crops, 400,000 tons of cotton and 100,000 tons of sugarcane . The anecdote about the disaster caused by rats has been too much, amazing and frustrating. In 1980, as many as 3,000 children in Colombia were bitten by rats and some were killed alive. In the same year, the Egyptian mice, acting in unison, occupied four provinces and ravaged the eastern side of the Nile Delta. They presided over the presidential decree to annihilate the rats. In India, about a fifth of the food in the field is eaten by rats every year. Rats throughout the world consume at least 50 million tons of food each year, enough to feed 200 million people.
