Excito-repellency test system
摘要:
An apparatus for measuring insecticide activity. A chamber holds a plural of insects and a quantity of the insecticide to be tested. An exit is formed in the chamber so that insects escaping from the chamber pass through a detector to generate a signal. The signals are compared to other signals generated by the other insects passing the detector to determine the repellency of the insecticides.
