Raspberry Ketone Trifluoroacetate, a new attractant for the Queensland fruit fly (Bactrocera tryoni (Froggatt)). Journal of Chemical Ecology. 42:156-162.Interpretive Summary: In this paper the behavioral response of Bactrocera tryoni, a pest of agricultural concern, to a new lure is investigated using cameras and electrophysiological techniques. The new lure is a novel fluorinated analog of raspberry ketone, raspberry ketone trifluoroacetate (RKTA). We find a very strong behavioral response to this lure, stronger than lures currently in use, which indicates that it may be promising for programs aimed at detecting and suppressing this pest.
                                Technical Abstract: The Queensland fruit fly (Bactrocera tryoni, Q-fly) is a major agricultural pest in eastern Australia. The deployment of male lures comprises an important component of several control and detection strategies for this pest. A novel fluorinated analog of raspberry ketone, raspberry ketone trifluoroacetate (RKTA), has been developed with the aim of further improving Q-fly control.  Quantification of Q-fly responses in a choice-test cage bioassay showed RKTA attracted and arrested more flies, 133 ± 4, than did cuelure, -99 ± 4. Similarly, RKTA also attracted and arrested more flies, 91 ± 3, than did melolure, -29 ± 3. RKTA also elicited strong electroantennogram (EAG) responses from Q-flies, while cuelure and melolure responses were not significantly greater than a negative control. However, the Q-fly EAG responses to RKTA are likely due at least in part to trifluoroacetic acid, which is a hydrolysis product of RKTA and elicits strong EAG responses when tested alone.
