No fully diagnostic restriction enzymes, but a combination of several can be chosen to distinguish B. melanotus from other Bactrocera and species in other genera.

See Restriction enzyme haplotype chart and Diagnostic restriction patterns.

Host Range

Bactrocera melanotus has been recorded on 31 hosts across 18 families including Anacardiaceae, Caricaceae, Combretaceae, Fabaceae, Myrtaceae, Rutaceae and Sapindaceae (for a full list of recorded hosts see Leblanc et al. 2012).
