Abstract

Identification of pest species in oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae) species complex.

Abstract

Different identification methods to differentiate pest species B. carambolae from B. occipitalis, B. papayae from B. philippinensis, and B. dorsalis from B. papayae and B. philippinensis (in oriental fruit fly complex) are presented. These methods/techniques are based on aculeus length, aedeagus length, discal cell length, and scanning electron microscopy of tomentum pattern on prescutum. The character "scales on the distal end of eversible membrane of ovipositor" is reviewed. However, morphological characters could not differentiate the two species B. papayae and B. philippinensis.
