Plants influenced the evolution of plant-dwelling stink bugs' systems underlying communication with chemical and substrate-borne vibratory signals. Plant volatiles provides cues that increase attractiveness or interfere with the probability of finding a mate in the field. Mechanical properties of herbaceous hosts and associated plants alter the frequency, amplitude, and temporal characteristics of stink bug species and sex-specific vibratory signals. The specificity of pheromone odor tuning has evolved through highly specific odorant receptors located within the receptor membrane. The narrow-band low-frequency characteristics of the signals produced by abdomen vibration and the frequency tuning of the highly sensitive subgenual organ vibration receptors match with filtering properties of the plants enabling optimized communication. A range of less sensitive mechanoreceptors, tuned to lower vibration frequencies, detect signals produced by other mechanisms used at less species-specific levels of communication in a plant environment. Whereas the encoding of frequency-intensity and temporal parameters of stink bug vibratory signals is relatively well investigated at low levels of processing in the ventral nerve cord, processing of this information and its integration with other modalities at higher neuronal levels still needs research attention.
植物影响了以植物为栖息地的椿象利用化学信号和底物传播的振动信号进行交流的系统的进化。植物挥发物提供了线索，这些线索会增加椿象在野外的吸引力或干扰其找到配偶的概率。草本寄主植物和相关植物的机械特性会改变椿象物种和性别特异性振动信号的频率、振幅和时间特征。性信息素气味调谐的特异性是通过位于受体膜内的高度特异性气味受体进化而来的。腹部振动产生的信号的窄带低频特征以及高度敏感的亚膝器官振动受体的频率调谐与植物的过滤特性相匹配，从而实现优化的交流。一系列对较低振动频率敏感的机械感受器，能检测到在植物环境中以较低物种特异性水平进行交流时其他机制产生的信号。虽然在腹神经索的低水平处理中，椿象振动信号的频率 - 强度和时间参数的编码已经得到了较好的研究，但在更高神经元水平上对这些信息的处理及其与其他模态的整合仍需要研究关注。
