Behavioural observations of Nezara viridula suggested that the antennae could be involved in detecting the substrate vibrations important in intraspecific communication of these insects. Therefore the vibrosensitive properties of Johnston's organ, a mechanoreceptor sensitive to the movements of the antennal flagellum relative to pedicel, were investigated. Vibrational stimuli were applied to the proximal flagellar segment where activity in the antennal nerve was recorded via a tapered tungsten electrode inserted into the second antennal segment where Johnston's organ is located. Sensory cells of Johnston's organ scolopidia respond to low frequency substrate vibrations (below 200 Hz). Both fast and slowly adapting receptor cells are present. However, the sensitivity of Johnston's organ to substrate vibrations in Nezara viridula is much lower than that of vibroreceptors in their legs which are known to be involved in intraspecific vibrational communication.
对稻绿蝽的行为观察表明，触角可能参与检测这些昆虫种内通讯中重要的底物振动。因此，研究了江氏器的振动敏感特性，江氏器是一种机械感受器，对触角鞭节相对于梗节的运动敏感。将振动刺激施加到鞭节近端，通过插入江氏器所在的第二触角节的锥形钨电极记录触角神经的活动。江氏器弦音器的感觉细胞对低频底物振动（低于200Hz）有反应。同时存在快速适应和缓慢适应的感受器细胞。然而，稻绿蝽的江氏器对底物振动的敏感性远低于其腿部的振动感受器，已知腿部的振动感受器参与种内振动通讯。
