一、仓储昆虫与人类的关系在追溯昆虫的起源中,科学家们根据昆虫的化石记录与现代昆虫的比较,发现首先是无翅昆虫(如仓库中的衣鱼)出现在古生代的泥盆纪,距今大约4亿年,然后是有翅昆虫(如仓库中的所有的有翅昆虫)出现在古生代的石炭纪,距今大约3.5亿年(Borror,1976)。到中生代的三叠纪,距今大约2亿年前,昆虫的主要进化史基本结束,使得化石昆虫较之它的现代后代难于区别(Busvine,1980)。而人类的出现是新生代后期的冰河期,距今只不过100万年。表明昆虫在地球上的出现远比人类要早,而且和它们所栖息环境里的一切动植物,包括最高等的人类,建立了古老的历史关系。然而,人类只要还是为了自足进行的小量生产,就不需要产品的长时间储存,也不存在害虫对他们的食品和衣物的危害。随着社会的发展和生产力的提高,人类和农业的“自然平衡”(Balallce of nature)关系相继打破,大量产品的长期储存首次成为可能,仓储害虫也就自然成为一个社会问题了(Hinton,1945;Busvine,1980)。
First, the relationship between storage insects and human In tracing the origin of insects, scientists based on the fossil record of insects and modern insects, found that first of all, wingless insects (such as the warehouse of fish) appeared in the Paleozoic Devonian, About 400 million years ago, then winged insects such as all winged insects in the warehouse appear in the Paleozoic Carboniferous about 350 million years ago (Borror, 1976). To the Mesozoic Triassic, about 200 million years ago, the major evolutionary history of insects basically ended, making fossil insects more difficult to distinguish from their modern descendants (Busvine, 1980). The appearance of mankind is the glacial phase of the late Cenozoic, only a million years ago. It shows that insects appear much earlier on earth than humans and that they have established an ancient historical relationship with all the flora and fauna in their habitat, including the highest humans. However, as long as human beings are still producing small quantities for self-sufficiency, they do not require prolonged storage of the product nor do pests damage their food and clothing. With the development of society and the improvement of productivity, the “Balallce of nature” relationship between mankind and agriculture has been broken one after another, and long-term storage of a large number of products is made possible for the first time. It is also a natural social problem for pests to be stored (Hinton, 1945 ; Busvine, 1980).
