Pacific Fruit Fly Project

Pacifly is the Pacific 's fruit fly web page which contains information about economic and non economic species of fruit flies in all the Pacific Island Countries and Territorries. Fruitflies are serious pests throughout tropical and sub tropical countries. They constitute of one of the worlds major insect pest in fresh fruits and fleshy vegetables. In every PICT, there is at least one damaging endemic fruit fly species present. Fruitflies cause direct losses to  fruit production and  in instances  where exotic species became established in a country, very expensive eradication programes had to be carried out. The Pacifly aims to provide detailed information of everything related to Fruit flies.

DISTRIBUTION: Widespread in Papua New Guinea (but not yet recorded from Manus or from the Highlands) and Solomon Islands.

HOST PLANTS: It has been consistently bred from one host species: Tahitian chestnut (Caesalpinaceae: Inocarpus fagifer), though its actual host range is probably more extensive.

BIOLOGY: Contrary to other species that infest only the outer fleshy part of Tahitian chestnut, B. moluccensis larvae damage the entire fruit, including the inner nut.

ECONOMIC IMPORTANCE: This species and mango fly collectively account for 28-42% infestation on 20% of Polynesian chestnuts around Port Moresby, Papua New Guinea.

MALE LURE: Cue-lure.

QUARANTINE SURVEILLANCE: Cue-lure trapping and regular host fruit surveys of Tahitian chestnut.

OPTIONS FOR RESPONSE (If newly discovered in a country): Increased trapping, increased host fruit sampling, restriction of fruit movement, protein bait spraying.

CONTROL: Fruit bagging, protein bait spraying, destruction of fallen and overripe fruits, early harvest of mature green fruits.
