Chemical analyses, using Solid Phase Microextraction and GC-EAD, of head space volatiles from hawthorn and flowering dogwood fruit have resulted in the identification of chemicals that may be involved in host fruit discrimination by Rhagoletis fruit flies that infest each fruit type. Several chemicals that elicited high EAD activity are common to the two fruit types, whereas others are unique to each. The chemical analysis forms the foundation for selection of candidate odor blends for behavioral assays of odor discrimination in flies from each fruit type.
