Our approach is to collect authentic pheromones from live ‘calling’ females and/or clipped abdominal tips and or plant kairomones from host plants and using headspace collection and or tip extraction to identify the chemicals present using GC-MS. Electrophysiological studies will be employed to identify biologically active constituents using GC-EAD on insect antenna. Those with activity will be tested and formulated for testing in a flight tunnel bioassay or other laboratory apparatus and if possible in the field. Next the pheromone and/or semiochemical will be synthesized and lures used to conduct field evaluations. Specifically, we would like to correlate capture of targeted invasive species to field populations and damage levels in the different cropping systems unique to Hawaii. Lastly we hope to use semiochemicals in potential control tactics. Identify and deploy systems approaches for fruit flies.
