A method and apparatus are described which combine visual and olfactory stimuli such that behavioral responses of fruit flies to test chemicals can be readily assessed. In the method of the invention, the test chemical is placed in a chamber, air is drawn past the sample to enhance volatilization and increase the concentration of volatiles in the air, the concentrated volatiles are blown in the vicinity of a substrate which visually mimics the fruit fly host plant in a concentration sufficient to elicit a behavioral response, and the responses are observed.
