Host Range

Polyphagous. Recorded from 49 hosts in 28 families including Anacardiaceae, Caricaceae, Rutaceae, Passifloraceae, Lauraceae, Leguminosae, Malvaceae, Moraceae, Myrtaceae and Solanaceae. Commercial hosts include mango, papaw, avocado, passionfruit, Tahitian chestnut, breadfruit, jackfruit, guava, rose apple, Malay apple, cocoa, coffee, citrus, star apple and chilli (see Leblanc et al. 2012).

Major commercial hosts:

  • Anacardium occidentale (cashew nut)
  • Carica papaya (papaw)
  • Citrus aurantiifolia (lime)
  • Citrus reticulata (mandarin)
  • Mangifera indica (mango)
  • Passiflora edulis (passionfruit)
  • Passiflora quadrangularis (giant granadilla)
  • Persea americana (avocado)
  • Psidium guajava (guava)
  • Solanum melongena (eggplant)
  • Theobroma cacao (cocoa)


Fiji Islands, Niue, Wallis and Futuna. There is also a separate form of B. passiflorae with paler abdomen. This is probably an undescribed new species which occurs in Fiji, Tuvalu, Tokelau and possibly the Niuas group in Tonga. Its host range and potential pest status have not yet been well studied (SPC 2006).

Similar species

Bactrocera passiflorae is similar to B. melanotus from the Cook Islands in being all black but differs in having pale legs and scutellum and black postpronotal lobes.


Pest Status

  • Exotic
  • Significant pest in the Pacific region it occurs in
