show Abstracthide AbstractThe Oriental fruit fly Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), is native to tropical Asia and has invaded and become established over much of sub-Saharan Africa and the Pacific Islands, and its incursions are often intercepted by plant protection services in the USA and other countries. Bactrocera dorsalis is widely recognized as either one of the most damaging horticultural pests where it occurs or as a high level quarantine threat to fruit production of importing countries where it is absent but capable of invasion and establishment. Bactrocera dorsalis males, like many other Bactrocera species, are strongly attracted to methyl eugenol (ME).
