B. kirki cannot be distinguished from B. frauenfeldi or B. trilineola.

No distinctive restriction enzymes, but a combination of several can be chosen to distinguish this group from other Bactrocera and species in other genera.

See Restriction enzyme haplotype chart and Diagnostic restriction patterns.

Similar species

Bactrocera kirki is similar to members of the B. frauenfeldi complex but differs in not having a distinct transverse band on the wing, although it has infuscation on the r-m and dm-cu cross veins.

Apart from lacking the wing band it is similar to:

  • B. frauenfeldi but lacks vittae, has yellow ppn lobes, has a black scutellum with yellow margins, and very thick medial line on abdomen.
  • B. albistrigata but lacks vittae, has a black scutellum with yellow margins, and very thick medial line on abdomen
  • B. trilineola but has facial spots (instead of a mask), yellow ppn. lobes

It is similar to B. psidii but lacks vittae, has a wide black band on the scutellum (instead of a triangle) and has 2 yellow longitudinal bands on the abdomen. See Bactrocera frauenfeldi complex and similar species for other separating characters.

Pest Status

  • Exotic
  • Bactrocera kirki is considered a major pest, and perhaps the most significant in the South Pacific region
