Morphology-based identification

Bactrocera jarvisi can be identified reliably based on morphology. A spot character is its presutural yellow marking; the postpronotal lobe and notopleuron are connected by a yellow band.

Molecular identification

COI sequence data can be used to reliably identify B. jarvisi.

Distribution

Bactrocera jarvisi is found across Australia. A genome-wide SNP analysis found two populations in B. jarvisi; one restricted to western Australia and one restricted to eastern Australia (Manawaduge et al. 2023Manawaduge et al. 2023:
Manawaduge CG, Clarke AR, Hurwood DA, 2023. Divergent east-west lineages in an Australian fruit fly, (Bactrocera jarvisi), associated with the Carpentaria Basin divide. Knapp M (Ed.). PLOS ONE 18: e0276247. https://doi.org/10.1371/journal.pone.0276247
). The molecular data suggested the eastern population represents the native range, and the western population is the result of a recent introduction event.

Further information

Bactrocera jarvisi is listed as a "category B" polyphagous pest in Australia in Vargas et al. (2015)Vargas et al. (2015):
Vargas RI, Pinero JC, Leblanc L, 2015. An overview of pest species of Bactrocera fruit flies (Diptera: Tephritidae) and the integration of biopesticides with other biological approaches for their management with a focus on the pacific region. Insects 6: 297–318. https://doi.org/10.3390/insects6020297
. A category B pest is there defined as "polyphagous fruit pests or destructive specialists more restricted in distribution, but at elevated risk of spreading to new locations". Bactrocera jarvisi was the first species of Dacini that was recognized to be attracted to zingerone (Fay 2012Fay 2012:
