摘　　要：柑橘小实蝇是起源于热带、亚热带有害生物,曾被认为是果蔬"头号杀手"。台州橘区在2007年首次报道发现柑橘小实蝇后,连续3年在局部橘园为害特别严重。但2010年后却很难查见柑橘小实蝇的为害,为探讨柑橘小实蝇为何不能在台州长期定殖原因,根据其生活习性,分析提出了柑橘小实蝇成虫群迁集中为害的可能性,以及气候条件、生态环境、寄主植物和土壤条件综合影响的结果。这对相似生态区柑橘小实蝇的检疫防控有积极的指导意义。Dacus dorsalis, a pest that originated in tropical or subtropical areas, is considered to be the top killer of fruit and vegetable. Dacus dorsalis was first reported in Taizhou in 2007, and seriously damaged partial local citrus orchards for 3 consecutive years. However, Dacus dorsalis has hardly been discovered since 2010 in Taizhou. In order to make sure the reason that Dacus dorsalis cannot colonize for a long time in Taizhou, the possibility of collective migration and centralized damage of Dacus dorsalis was analyzed, and the comprehensive influences of climate condition, ecological environment, host plant and soil condition were analyzed. The research has certain significance for quarantine and control of Dacus dorsalis in similar ecological regions.
