^aAll chemicals were tested in an amount of 50 μg per filter paper strip with ten different EAG preparations.

^bEAG responses were standardized to the responses to 50 μg C14:0ME on filter paper strip, which were scaled to a value of 1 and 0.58 from mated male in photo- and scotophase and to 0.06 and 0.09 from mated female in photo- and scootphase according to the ratio of mean absolute EAG values.

^cEAG responses from female and male in scotophase were tested within a two-hour period from 3 to 5 hours after the start of darkness under a red 10-watt light bulb.

^dEAG responses from female and male in photophase were tested within a two-hour period from 1 to 3 hours after light onset.

^eDifferent letters after EAG values indicated significant differences (P<0.01) among the test chemicals in each of the two test periods by ANOVA and Duncan’s multiple range test (DMRT).

^fDifference of EAG values elicited by individual test chemical between scotophase and photophase was compared by Student’s t test.
