- Bactrocera kirki - guava, mango, avocado; Bactrocera passiflorae - guava, citrus, mango, kavika; Bactrocera xanthodes - breadfruit, jackfruit, papaya; many more hosts, and fruit fly species occur.
- Note, Bactrocera kirki is present only on Rotuma.
- Females need protein before they can lay viable eggs.
- Cultural control: bag fruit with paper or leaves; collect fallen fruit and destroy; harvest early (banana and papaya); some non-hosts, e.g., chilli, pineapple.
- Chemical control: use a commercial protein bait spray, e.g. MPPIL, Royal Tongalure or Bactrogel.

Fiji fruit flies (170)
There are seven fruit flies in Fiji: The species of economic importance are: (i) Bactrocera kirki (no common name), (ii) Bactrocera xanthodes (the Pacific fruit fly), (iii) Bactrocera passiflorae (Fijian fruit fly), (iv) Bactrocera distincta, and (v) Bactrocera species near passiflorae. Bactrocera gnetum and Bactrocera obscura are not of economic importance.
Bactrocera distincta, Bactrocera kirki, Bactrocera gnetum, Bactrocera obscura, Bactrocera passiflorae, Bactrocera species near passiflorae, and Bactrocera xanthodes. Bactrocera xanthodes is closely related to three other species: Bactrocera paraxanthodea in New Caledonia, and Bactrocera neoxanthodes in Vanuatu, and a species not yet described from Samoa.
