实蝇是一类危害热带、亚热带水果蔬菜的重要害虫。调查表明,实蝇由入侵引起的种间竞争,一个突出现象就是实蝇种间的入侵具有显著的等级特征,种间竞争性替代具有强烈的方向性,其竞争作用可导致入侵实蝇种群的灭绝或者数量的巨大改变。目前有关实蝇种间竞争的等级性模式既未得到进一步研究验证,也未明确其中隐含的作用机制。深入研究实蝇种间竞争的作用机制为检疫性实蝇的风险评估和管理提供参考,同时也为认识农林害虫群落的演替规律提供理论依据。
Fruit flies are a type of important pests that endanger tropical and subtropical fruits and vegetables. The survey shows that the interspecific competition caused by the invasion of fruit flies is a prominent phenomenon that the interspecific invasion of fruit flies has a significant level of characteristics. The competitive alternative of interspecies has a strong direction, and its competition effect can lead to invasion of fruit flies population Extinct or a huge change in the number. At present, the hierarchical pattern of interspecific competition between fruit flies has not been verified by further research and the mechanism of action implied in it is not clear. In-depth study of the mechanism of interspecific competition in fruit flies provides a reference for the risk assessment and management of quarantine fruit flies, and also provides a theoretical basis for understanding the succession rules of forest and pest communities.
