Throughout Asia, Australia and the Pacific, and increasingly in Africa, the primary horticultural insect pests are fruit flies belonging to the genera Bactrocera, Zeugodacus and Dacus (Diptera: Tephritidae: Dacini). This group includes species such as Oriental fruit fly (B. dorsalis), Melon fly (Z. curcurbitae), Queensland fruit fly (B. tryoni) and the Olive fly (B. oleae). All these species lay their eggs into fleshy fruits and vegetables, where the maggots feed, so destroying fruit and hindering market-access. In addition to being pests, the Dacini is also a hugely diverse clade of nearly 900 species endemic to the rainforests of Asia/Australia and the savannas of Africa. Despite their economic and ecological importance, there is no single source which can provide students, field entomologists, extension officers, quarantine officers and market access negotiators with a rapid, yet comprehensive introduction to the group.
