Two techniques are described to distinguish immature Bactrocera tryoni (Froggatt) rapidly from Mediterranean fruit fly, Ceratitis capitata Wiedemann. These techniques were adopted as an integral part of a major program to eradicate B. tryoni in southwestern Australia. To monitor the success of the program it was necessary to identify larvae and pupae of each species extracted from large numbers of fruit samples collected over the infested area. Morphological differences in the cephalopharyngeal skeleton enabled living and dead forms of both stages to be distinguished. During the latter stages of the program the bulk of the live larvae collected were assayed by electrophoresis. The costs and benefits of each technique are discussed; however, we believe that the techniques Cornplement each other.
