The present invention provides a method for evaluating the taxic behavior of nematodes in response to an odor substance based on olfactory sense, and a dish and a behavior evaluation system to be used for the evaluation method. [Solution] Provided is a method for evaluating the taxic behavior of nematodes in response to odor of a test sample, the method including: a) providing a dish in which the test sample is arranged on the bottom surface, and nematodes are arranged in a region or a site of the bottom surface 1 cm to 3 cm away from the test sample; b) observing the arrangement of the nematodes on the bottom surface at 3 to 15 minutes after the later one of the test sample or the nematodes is arranged; and c) evaluating whether the nematodes show attraction behavior or avoidance behavior in response to the test sample, from the arrangement of the nematodes observed, and a dish or a taxic behavior evaluation system suitable for the method.
