Method for evaluating taxic behavior in response to odor substance based on olfactory sense in nematodes, and dish and behavior evaluation system used in evaluation method

摘要

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.
