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: Known so far only from East New Britain province, in Papua New Guinea.

HOST PLANTS: Only one host recorded: pumpkin (Cucurbitaceae: Cucurbita pepo).

BIOLOGY: Larvae of this species infest pumpkins, and can co-exist with melon fly larvae, but their rate of development is much slower. Attempts to keep this species in laboratory colonies in Papua New Guinea have not yet been successful.

ECONOMIC IMPORTANCE: Damage assessments around Kerevat, East New Britain, show that up to 24% of pumpkins can be infested with melon fly and pumpkin fruit fly. Species can co-exist in one pumpkin.

MALE LURE: This species does not respond to male lures.

QUARANTINE SURVEILLANCE: Regular host fruit surveys of pumpkins.

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

CONTROL: Protein bait spraying, destruction of damaged fruits.
