title: An olfactometer for bark beetle parasites.
abstract: An "H"-type olfactometer was designed and built to test the response of bark beetle parasites to various beetle and tree host odors. The design has several advantages over other types of olfactometers. Strong air currents are not utilized, parasites have free movement in the test chamber, and a concentration gradient of test compound is maintained. Parasites tested in the olfactometer demonstrated strong positive responses to air drawn over logs infested with bark beetle larvae and varied responses to tree host odors.
