摘要
表观竞争是资源竞争以外的一种新型的种间关系 ,是指由共同享有的自然天敌中介的、物种之间在种群数量上表现出明显负效应的现象。物种之间的表观竞争被认为和资源竞争具有同等的重要性 ,尤其是对植食性昆虫来说更为重要。近十年来关于昆虫表观竞争的理论和实验研究进展迅速 ,已成为昆虫生态学研究中的一个新的生长点。本文从表观竞争的定义、实验研究实例、理论模型、作用机制及共存机制等方面 ,对近些年来关于昆虫表观竞争研究的进展进行了概括和总结 ,并对表观竞争理论在害虫防治中的应用前景进行了展望。
Apparent competition is a new type of indirect interaction between spe cies that is different from resource-mediated competition. It is a phenomenon i n which two species that share a natural enemy negatively affect each [BF]other’ s [BFQ]abundance. It is now known that apparent competition is as important as r esource -mediated competition, especially for phytophagous insects. There has been gre at progress in theoretical and experimental aspects of apparent competition over th e last 10 years. This paper reviews recent studies on different aspects of appa rent competition in insects, including the underlying concepts, experiments, the oretical models, mechanisms of interaction and coexistence etc. The application of apparent competition in pest control is discussed.
