Commercial hosts include mango, guava, papaw, persimmon, avocado, banana, pomegranate, apple, peach, pear, citrus, edible Syzygium.

For a full list of recorded hosts see Hancock et al. 2000.

Major commercial hosts:

  • Carica papaya (papaw)
  • Mangifera indica (mango)
  • Musa species (banana)
  • Prunus persica (peach)
  • Psidium guajava (guava)


Northern Australia from Broome, Western Australia to eastern Arnhem Land, Northern Territory and northwest Queensland, Torres Strait islands and eastern Australia from Cape York to the Sydney district, New South Wales (Hancock et al. 2000).

In recent tests using zingerone, B. jarvisi was not detected in Sydney and the southern boundary is considered to be somewhere north of Sydney (Dominiak et al. 2015b).

Distribution is closely linked to the main host cocky apple (Planchonia careya) which has its southern boundary between Maryborough and Brisbane. Has been recorded from Indonesia (Irian Jaya) by White and Elson-Harris on one occasion but is not established there and should not be regarded as a permanent record (Drew 2010 pers. comm.).

Indonesia (West Papua); Papua New Guinea (Mainland) (Leblanc et al. 2012)

Similar species

Bactrocera jarvisi is similar to B. zonata but differs in having a joining band between the ppn. lobe and notopleural calli, a continuous costal band (instead of an isolated apical oval spot), anal streak present and a more defined T on the abdomen. It is also zingerone and cue-responsive whereas B. zonata is ME-responsive.
