摘要

自1988年5月至1990年3月，於台中縣、台中市、彰化縣、南投縣共調查發現非洲菊斑潛蠅（Liriomyza trifolii （Burgess））之寄生蜂7種，分別為釉小蜂科（Eulophidae）之異角釉小蜂（Hemiptarsenus varicornis（Girault））、底比斯釉小蜂（Chrysocharis pentheus（Walker））、岡崎釉小蜂（Chrysonotomyia okazakii（Kamijo））及Chrysonotomyia屬1種、黃金小蜂科（Pteromalidae）之Halticoptera屬2種、小繭蜂科（Braconidae）之Opius屬1種。其中異角釉小蜂發生最普遍，出現比例佔所有寄生蜂之51.5%，為非洲菊斑潛蠅在臺灣最常見之寄生蜂。岡崎釉小蜂為首次記錄寄生於非洲菊斑潛蠅。而Opius屬之1種極可能為新種。本文除探討寄生蜂之寄生率及其重要性，亦就7種寄生蜂製作檢索表，並分述各寄生蜂之寄主與發生情形以及地理分布。

Seven species of Hymenopterous wasps that are parasites on the American serpentine leafminer, Liriomyza trifolii (Burgess) were found under a survey conducted in central Taiwan from May 1988 to March 1990. They were Hemiptarsenus varicornis (Girault), Chrysocharis pentheus (Walked), Chrysonotomyia okazakii (Kamijo), Chrysonotomyia sp., Halticoptera sp.1, Halticoptera sp. 2, and Opius sp.. Over 51% of the parasitoid wasps collected in the field were H. varicornis; hence this species was considered the most important natural enemy of L. trifolii in Taiwan. C. okazakii (Kamijo) and undetermined Opius sp. were for the first time recorded as parasitoids of L. trifolii. We present a taxonomic key of these seven species. The host range, world distribution and the parasitic potential of each species are given and discussed.
