Abstract The oriental fruit fly, Bactrocera (=Dacus) dorsalis Hendel, is an economic important pest in Taiwan. Government and agricultural organizations have used the annihilation technique with attractants of poisoned methyl eugenol as a control method. The Braconid wasp, Diachasmimorpha (=Opius, =Biosteres) longicaudatus Ashmead, an efficient larval parasitoid of the oriental fruit fly, was introduced from Hawaii and has been successfully raised in the laboratory. This wasp will be used as an agent of biological control, and together with the annihilation technique will form an integrated control method. The important factors influencing parasitoid yield such as the culturing apparatus, host larva age, parasitoid maternal age and the exposure period to parasitoid oviposition as well as the biology of the parasitoid were studied. The parasitoids have been released into orchards.
摘要 東方果實蠅Bactrocera (=Dacus) dorsalis臺灣重要之經濟害蟲，每年政府及農業機構均耗費巨資，利用含毒甲基丁香油誘殺之滅雄技術防治該蟲。果實蠅幼蟲寄生蜂，Diachasmimorpha (=Opius,=Biosteres) longicaudatus，為1896-1987年從夏威夷引進之寄生蜂，已在實驗室內飼育成功，並將應用於果實蠅生物防治與滅雄技術之綜合防治。室內飼育技術之逐步改進、寄主和寄生蜂之寄生年齡、接受寄生產卵時間之長短、以及寄生蜂之生物學等經詳細研究均在本文中報告，此外，田間釋放寄生蜂之研究亦在進行中。
