Host Range

Polyphagous recorded from 9 hosts from 5 families including Cucurbitaceae, Loganiaceae, Musaceae, Passifloraceae and Solanaceae (for a full list of recorded hosts see Hancock et al. 2000).

It has been bred from banana in Papua New Guinea (Leblanc et al. 2001).

Major commercial hosts:

Capsicum annuum (chilli)


Indonesia (Papua, formerly part of Irian Jaya), Papua New Guinea (every province except Bougainville and Manus), and Australia (South East Queensland, Central Queensland, Northern Queensland, Northern Western Australia, Northern Territory, east coast south to Sydney, New South Wales, and the Torres Strait Islands) (Drew and Romig 2013).

Similar species

Superficially similar to B. dorsalis complex species in having a black scutum and T on the abdomen, except it is cue-responsive and has a very broad costal band to R4+5.

In cue traps it is most similar to B. trivialis except it has a distinct T on the abdomen and a very broad costal band.

Pest Status

  • Australian
  • Low level pest species in Queensland but not in Western Australia or the Northern Territory


Cue lure group. In north Queenslandd this species was significantly more attracted to Melolure (raspberry ketone formate) than cue-lure (Royer 2015).
