| 摘 要： | 保护利用天敌是农田害虫生物防治的基本手段。短期农作物生境中的天敌亚群落周期性地呈现出群落重建、群落发展和群落瓦解3个阶段。其中的重建阶段对抑制害虫的发生和危害至关重要。天敌亚群落的重建与其种库、群落本身和作物生态系统之间的相互作用关系，是群落水平上保护利用天敌的理论基础之一。因此，可以指导自然天敌的保护和持续利用，促进短期农作物生境中的害虫生物防治。

| Abstract: | Conservation and utilization of natural enemies is the basic measure in biological control of agricultural pests. The enemy sub\|community in short\|term crop fields appears periodically 3 different stages that are called community reestablishment, community development and community collapse. Pests usually cause damage to a crop 1~2 generations after their first occurrence in the field. During that period, enemy sub\|community that is still under reestablishment is crucial to control the pests. If pests ... |
