昆虫迁飞随气流散布若干问题的商榷

昆虫通过飞翔从一个生境迁移到另一个新的生境，是普遍存在的自然现象，而随气流远距离季节性迁飞是在特定环境条件下产生的，是昆虫与环境在进化过程中的统一。对于迁飞的个体，“从A迁飞到B，并在B获得生境”是随机事件，但对于迁飞的群体则存在统计规律。迁飞昆虫以被动的随气流散布方式，获得对环境的主动适应。

DISCUSSION ON INSECT MIGRATION WITH THE DISPERSION DIRECTED BY AIR CURRENT

It is a common phenomenon of nature that insect shifts from one habitat to another by flight, while its seasonal long distance migration in space with air current occurs in a special environment. It is one of the unifications of insect and environment during the course of evolution. The fact that an insect migrates from A to B and finds a habitat in B is a random event, but the migration of an insect population complies with certain statistic regularity. Thus, the migratory insect gets the initiative adaptation to the environment by using a passive mode, the dispersion directed by air current.
