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: Mainland Papua New Guinea (less common in the Highlands than at low elevations), Australia (Torres Strait Islands only), Indonesia (Irian Jaya, Sulawesi).

HOST PLANTS: Attacks 13 species of edible fruits in 11 genera and 10 families in PNG. It has been regularly bred from guava and Syzygium spp. Published host records are:

BIOLOGY: Not yet studied.

ECONOMIC IMPORTANCE: It infests 13-45% of guavas in the Central Province and up to 9% of oranges in the Highlands of Papua New Guinea.

MALE LURE: Cue-lure.

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

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

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