| 摘 要： | 在对昆虫迁飞进行雷达观测时发现，天敌（包括蜘蛛）种群的大规模伴迁现象引人注目，国内外的近捕、海捕中也都有天敌入网。这种同步迁移现象无疑具有重要的生态学和行为学意义，表现出“天敌－寄主－植物”不同营养层之间的相互作用。而温带和热带空中取样中伴迁天敌数量相差之巨，也突出反映了不同的生物多性背景。对低层大中的生物流量进行长期监测，可望从另一个层面提供可靠的生物多样性信息。

| Abstract: | It was found in radar observations and marine samples that the phenomena of accompanying migration by natural enemies (including aeronautic spiders) with their hosts was significant and spectacular. The phenomena shows that the interaction between different trophic levels of natural enemy insect and pest plant is undoubtedly of important ecological and behavioral significance. The great difference of natural enemy catches in aerial samples between different areas in the tropics and the temperate zone reflects the different backgrounds of biodiversity. The long term monitoring of bio flux in the low level atmosphere would provide reliable information on biodiversity. |
