Similar species

Bactrocera correcta is similar to the exotic B. dorsalis but differs in having transverse facial spots, an apical wing spot instead of a costal band and costal cells devoid of microtrichia. It is similar to B. zonata but has a predominantly black scutum.

Pest Status

• Exotic
• Major pest species, particularly in Vietnam

Attractant/Lure

Beta-caryophyllene is a species-specific attractant for B. correcta that is more attractive than methyl eugenol (Wee et al. 2017).
