The fitting curves were drawn by Igor pro ver.4.0, under the hypothesis that all the discriminators could show biting behavior toward infinitely large amounts of CHCs, regardless of their nests. The CHC amounts giving half the maximum response, which is defined as the mean threshold amounts of CHCs for inducing biting behavior, are indicated by arrowheads.
