Bactrocera dorsalis, also known as the Oriental fruit fly, is a highly polyphagous invasive pest originating from tropical south east Asia. It has invaded over 50 countries, causing significant economic damage to a wide range of fruit and vegetable crops through oviposition and larval development. The species thrives in tropical and subtropical climates, with potential to spread to warm temperate regions under irrigation or climate change. Classical biological control efforts against B. dorsalis have primarily involved the introduction of parasitic wasps, such as Fopius arisanus and Diachasmimorpha longicaudata. F. arisanus has shown high effectiveness, with significant reductions in B. dorsalis populations in Hawaii, French Polynesia, and parts of Africa, while D. longicaudata has been less successful. F. arisanus is considered the most promising biological control agent due to its high parasitism rates and adaptability, though it has not established in all regions. Other natural enemies, including various hymenopteran parasitoids and the predatory ant Oecophylla longinoda, have shown limited effectiveness and potential ecological drawbacks. Combining F. arisanus with other biological control agents targeting different life stages of B. dorsalis could enhance overall control efforts.
