How the olfactory instrument works
The air compressor passes the clean plume gas filtered by the air filter at a constant pressure and flow rate through the air inlet of the trap bottle (or the inlet hole of the connecting pipe), and the information odor substances in the trap bottle are mixed with the clean air. An air flow with different odors is formed, enters the central activity chamber through four arms and mixes, and then flows out from the top air outlet. Before the test, put the test insects with the same physiological indicators from the air outlet into the central activity room. When the air path is opened, the test insects meet the turbulent flow of gas with information material in the central activity room, and then fly upwind into the specific arm Then, follow the concentration gradient of the odor into the trap bottle that can only enter and not exit. After testing for a certain period of time, check the number of test insects in each trap bottle, calculate the response rate, trap rate and selection coefficient according to the following formula, and test the trap rate of the treatment and control (percentage data is square root converted).
