Our facility is equipped with Y-Tube Olfactometers of varied sizes that test responses of various insects to plant volatiles.
An adult insect is released at the base of the Y-Tube. A gentle flow of air is passed through one fork of the Y-Tube, while an attractant/repellent is passed through the other fork. The insect walks upwind to the end of one of the forks.
We use this technique to understand and measure the effectiveness of an attractant or repellent.
