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
The present invention provides a method for evaluating taxic behavior in response to an odor substance based on the olfactory sense in nematodes, and to a Petri dish and a behavior evaluation system used in the evaluation method. [Solution] The present invention is a method for evaluating taxic behavior in nematodes in response to a test sample odor, wherein the method includes the steps of a) providing a Petri dish in which a test sample is disposed on a bottom surface thereof, a nematode being disposed in a region or position of the bottom surface 1 cm to 3 cm away from the test sample, b) observing the placement of the nematode on the bottom surface 3 to 15 minutes after placement of the test sample or the nematode, whichever was placed last, and c) evaluating, from the observed placement of the nematode, whether an attractive behavior or an evasive behavior with respect to the test sample was exhibited. The present invention is also a Petri dish or a taxic behavior evaluation system suitable for the method.
