Social facilitation of insect reproduction with motor-driven tactile stimuli
Proceedings of the Royal Society B: Biological Sciences, 281(1783), 20140325.
author keywords: social facilitation; tactile stimuli; reproduction
MeSH headings : Animals; Arthropod Antennae / physiology; Blattellidae / physiology; Female; Mechanoreceptors / physiology; Motor Activity; Reproduction; Social Facilitation; Touch
TL;DR:
The results indicate that tactile stimulation with artificial materials, some deviating significantly from the native antennal morphology, can facilitate female reproduction, however, none of the artificial stimuli matched the effects of social interactions with a conspecific female.
