Taxonomy of Korean Bactrocera (Diptera: Tephritidae: Dacinae) with review of their biology

The genus Bactrocera Macquart, currently comprising over 650 described species, is the most economically significant fruit fly genus with at least about 50 species considered to be pests of agricultural and quarantine importance. As a part of effort to investigate both agricultural and quarantine Bactrocera pests in Korea, the present study aims at reviewing the naturally occurring Bactrocera species in this country. Two Bactrocera species, pumpkin fruit fly (B. depressa (Shiraki)) and striped fruit fly (B. scutellata (Hendel)), are currently recognized in South Korea. Bactrocera depressa is an important agricultural pest infesting pulp of host fruits including pumpkins, and B. scutellata is known to infest flower buds of pumpkins as well as other cucurbit hosts. We recently found the third Bactrocera species, B. hyalina (Shiraki), for the first time in Korea. We here provide a taxonomic key to the Korean Bactrocera species, brief review of their biology, summary of their taxonomic status, diagnoses, descriptions, and detailed photographs of adults including postabdominal structures for their accurate identification. In addition, we here synonymize Zeugodacus bezzianus Hering with B. depressa.
