Males and females of the green stink bug Nezara viridula produce species and sex specific vibrational signals. The songs of bugs from geographically isolated population differ in their temporal characteristics. Hybrids were produced between the bugs from Brazilian and Slovenian populations in order to examine the levels of genetic inheritance of their vibratory songs. Hybrid males and females produced songs which are distinctly different from parental songs and these differences can be attributable to genetic factor. The results show that in some parameters the hybrid songs are intermediate between the parental types. Several song parameters are apparently sex-linked. It remains to be established whether observed genetically determined differences in vibratory songs also indicate that cryptic species exist within the taxon N. viridula.
绿蝽Nezara viridula的雄性和雌性会产生特定物种和性别的振动信号。来自地理隔离种群的蝽的鸣声在时间特征上有所不同。为了研究其振动鸣声的遗传继承水平，在来自巴西和斯洛文尼亚种群的蝽之间培育了杂交种。杂交雄性和雌性产生的鸣声与亲本的鸣声明显不同，这些差异可归因于遗传因素。结果表明，在某些参数上，杂交鸣声介于亲本类型之间。几个鸣声参数显然与性别有关。尚有待确定，在振动鸣声中观察到的由基因决定的差异是否也表明在绿蝽分类单元中存在隐性物种。
