边缘效应是生态系统和其它系统中的一种重要现象。在储粮生态体系中也存在着边缘效应,且对储粮害虫的发生、繁殖、活动及其在粮堆中的分布均有影响。开展对该边缘效应的讨论、研究及利用,将推动储粮害虫防治工作的进一步发展。王如松和马世俊(1984)把 Beecher(1942)的生态系统边缘效应概念拓展为:在两个或多个不同性质的生态系统(或其它系统)交互作用处,由于某些生态因子(可能是物质、
Marginal effects are an important phenomenon in ecosystems and other systems. There is also a marginal effect in the stored grain ecosystem and affects the occurrence, reproduction, activity of stored grain pests and their distribution in the grain piles. Carrying out the discussion, research and utilization of this fringe effect will promote the further development of stored pest control. Wang Rusong and Ma Shijun (1984) extended Beecher’s (1942) concept of ecosystem edge effects to the interaction between two or more ecosystems (or other systems) of different nature due to certain ecological factors (which may be material,
