DescriptionWe investigated the relative importance of olfaction versus vision in the mate-finding behavior of Agrilus planipennis. When coupled in male-female, male-male and female-female pairs, attempts to mate occurred only in the male-female pairs, suggesting that beetles can identify the opposite sex before attempting to mate. In a set of sensory deprivation experiments with male?female pairs, we evaluated whether males could find females when deprived of their sense of olfaction, vision or both. Males whose antennae were blocked with model paint took significantly longer to find females and spent less time in copula compared to untreated males. Males whose eyes were similarly blocked did not differ in their mate finding capacity compared to untreated males. In a third experiment that compared both olfaction and vision, olfactorily impaired beetles never mated whereas the mate finding potential of visually impaired beetles did not differ from that of untreated beetles.
