2013 Annual Report
A series of field experiments determined that several chemicals from wine and vinegar odor that are internally active are deterrent to the spotted wing drosophila. These deterrent compounds were then removed from the chemical blend tested developed and reported in 2012, and were field tested in Mississippi and Oregon. The results show a significant improvement in the power of the lure for the fly, which is now down to four compounds. Subsequent studies focused on optimizing the amounts of the chemicals used in the lure, and the development of a less expensive means of providing controlled release of the chemical attractant for use in traps. At this time, we have a controlled release dispenser for two of the four compounds that provides optimum amounts of the chemicals.
