Abstract: Bactrocera dorsalis Hendel (Diptera: Tephritidae) is an invasive pest. Owing to its potential damages and rapid spread, it has been considered as an important quarantine pest in China. For improving the precaution of this invasive pest by all kinds of people, the biology and ecology of this pest were been introduced in this paper.
