Abstrakt		The female southern green stink bug Nezara viridula (Heteroptera: Pentatomidae) calling song starts substrate-borne communication and triggers different stereotyped responses in males. We tested the species specificity level of male N. viridula responses to stimulation with songs of N. viridula, Thyanta pallidovirens and Thyanta custator accerra (Heteroptera: Pentatomidae) in two natural situations and correlated the response magnitude with temporal properties of the conspecific and heterospecific stimulatory songs. Emission of the male courtship song together with locating of the vibration source proved to be the most species-specific reaction. However, even at this level males did not discriminate between the conspecific female calling song and second male calling song of T. custator accera , which have similar pulse duration and repetition time values. The concept of species specificity of signals involved in the calling phase of mating behaviour is discussed
