Abstract

Positive phonotaxis occurs when a female cricket walks toward the source of an auditory stimulus. This study tested the effects of light intensity and time of day on phonotaxis of female Acheta domesticus. First, females were tested at four times of day; second, under three light intensities; and third, under four combinations of light intensity and time of day. Our results show that these two factors combined exert a more pronounced effect on female A. domesticus selectivity than either factor individually, and subsequent research will test these factors against the current neuronal model for SP-selective phonotaxis.
