前言飞蝗成群的迁飞和为害为人们所熟睹,所以我国在数千年前就有关于蝗虫迁飞为害的记载(周尧,1980)。蜻蜓、蚂蚁等昆虫的成群迁飞也是屡见不鲜的现象。但有许多害虫都是在经过试验研究论证之后,才认识到它们的迁飞现象。我国处于东亚季风地带,迁飞昆虫的种类很多,据1989年10月举行的全国迁飞昆虫学术讨论会提出的已经开展研究的迁飞昆虫近20种,实际上迁飞昆虫种类远高于此数。据目前的认识,迁飞是昆虫适应环境变化,经长期演化形成的一种生态对策,它是生活史的重要组成部
Foreword Migratory locust swarms and evils are well known to all, so thousands of years ago our country had records of the loss of locusts (Zhou Yao, 1980). Dragonfly, ants and other insects flocks flying is also a common phenomenon. However, many pests only recognize their migration after they have been tested and proved. China is in the monsoon zone of East Asia and has many species of migratory insects. According to the National Migration Insects Symposium held in October 1989, nearly 20 species of migratory insects have been studied. In fact, the species of migratory insects are much higher than this number. According to the current understanding, migration is a kind of ecological countermeasure that insects adapt to environmental change and formed by long-term evolution, which is an important part of life history
