振动通信是人们最不了解的通信渠道之一。大多数研究都集中在昆虫交配行为中的底物传播信号的作用，其中雄性和雌性建立一个刻板的二重唱，使合作伙伴识别和定位。虽然基片传播信号的有效通信范围可达几米，但通常认为昆虫振动通信仅限于连续的基片。到目前为止，植物之间没有物理接触的植物间交流从未在振动交流昆虫中得到证实。用激光测振仪，我们调查了自然的传输和播放的振动信号的葡萄藤叶蝉，Scaphoideus titanus，当被传送到不同的插条之间的叶子没有物理接触。合作伙伴建立了一个振动二重奏高达6厘米的差距之间的叶子。消融的触角表明，触角机械感受器是不是必不可少的交配信号的检测。我们的研究结果首次表明，基板不连续性不施加限制振动信号的通信范围。我们还认为，行为反应可能取决于信号强度。
Vibrational communication is one of the least understood channels of communication. Most studies have focused on the role of substrate-borne signals in insect mating behavior, where a male and a female establish a stereotyped duet that enables partner recognition and localization. While the effective communication range of substrate-borne signals may be up to several meters, it is generally accepted that insect vibrational communication is limited to a continuous substrate. Until now, interplant communication in absence of physical contact between plants has never been demonstrated in a vibrational communicating insect. With a laser vibrometer we investigated transmission of natural and played back vibrational signals of a grapevine leafhopper, Scaphoideus titanus, when being transmitted between leaves of different cuttings without physical contact. Partners established a vibrational duet up to 6 cm gap width between leaves. Ablation of the antennae showed that antennal mechanoreceptors are not essential in detection of mating signals. Our results demonstrate for the first time that substrate discontinuity does not impose a limitation on communication range of vibrational signals. We also suggest that the behavioral response may depend on the signal intensity.
