Claim 13:
14. A method for applying olfactory response of a live organism test subject to a particular odorant, comprising the steps of:
a. providing an enclosed space with two or more individual discrete odor zones distributed within or around a defined background odor zone within the enclosed space,
b. causing the organism test subject to enter a background odor zone within the enclosure,
c. generating two or more discrete odor zones within said enclosed space, by means comprising an inlet to deliver a gaseous fluid and an outlet to remove said gaseous fluid, for each of the discrete odor zones, wherein said inlet and outlet for each discrete odor zone is positioned so that each discrete odor zone is spatially separated from every other discrete odor zone within said enclosed space by at least a portion of a background odor zone within the space,
wherein at least one of said inlets for delivering gaseous fluid comprises an inner pipe, and at least one of said outlets to remove said gaseous fluid comprises an outer pipe having a greater diameter than the inner pipe, and wherein the inner pipe extends within and protrudes through the outer pipe,

d. introducing a live arthropod test subject into the defined background odor zone,
e. recording the behavior of the live arthropod test subject in response to the odorant, and
f. if the particular odorant is found to be an attractant for the arthropod, deploying the odorant in pertinent concentration to attract such organisms to places where they are not undesirable, and g. if the particular odorant is found to be a repellant, deploying the odorant in pertinent concentration to repel such organisms away from places where they are undesirable.
