Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of test instrument, concretely relates to an insect olfactory behavior detection device. BACKGROUND

[0002] In the field of insect tropism research, in order to study its tropism to different odors, it is necessary to use an olfactometer to determine. Common olfactometers include Y-type olfactometer, four-arm olfactometer and single olfactometer, and the main working principle is to send the information substance diffused by the odor source to the initial environment of the test insect at a constant pressure and flow rate, so as to achieve the attraction to the test insect. However, the structure of the existing equipment is relatively complex, and the production cost is high. Patent CN203206986U provides an insect tropism observation device without an air compressor, which is simple in structure and low in manufacturing cost.
