| Outline of Final Research Achievements |
Cerambycid beetles often demonstrate an antennal response to touch their conspecifics or some objects approaching them from behind. This visual-dependent response was enhanced when they were provided a visual target along with low-frequency waves perceived by their femoral chordotonal organs. When ‘footstep’ vibrations of walking conspecifics were played, adults Monochamus alternatus responded to the visual target at a similar rate as that when 100-Hz vibrations were played. We propose that the cross-modal effect of vibration could compensate for the reduced visual sensing and provide nocturnal species a better chance to find their mates. Cross-modal effect was also observed between visual and vibrational cues in dropping behavior of M. alternatus, and between visual and olfactory cues in enemy avoidance of some other species. We consider that insects can behave intelligently by using multimodal information, i.e., using more than one sensory cue with different modes simultaneously.
