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.

Drawing of male B. distincta (Drawing: M. Romig)

 

DISTRIBUTION: Fiji Islands, Tonga, Samoa, American Samoa, Futuna.

HOST PLANTS: It infests 10 host species, in 9 genera and 5 families, but mostly in the family Sapotaceae. There are several more records that need to be confirmed. Published host records in Fiji, Tonga and Samoa are:

BIOLOGY: Adults of this species mate at dusk.

ECONOMIC IMPORTANCE: Insignificant.

MALE LURE: Cue-lure.

QUARANTINE SURVEILLANCE: Cue-lure trapping and regular host fruit surveys of sapodilla and star apple.

OPTIONS FOR RESPONSE (If newly discovered in a country): Increased trapping, increased host fruit sampling.

CONTROL: Probably not necessary, but options are fruit bagging, protein bait spraying, destruction of fallen and overripe fruits.
