We investigate the role of the noise in the mating behavior betweenindividuals of Nezara viridula (L.), by analyzing the temporal and spectralfeatures of the non-pulsed type female calling song emitted by singleindividuals. We have measured the threshold level for the signal detection, byperforming experiments with the calling signal at different intensities andanalyzing the insect response by directionality tests performed on a group ofmale individuals. By using a sub-threshold signal and an acoustic Gaussiannoise source, we have investigated the insect response for different levels ofnoise, finding behavioral activation for suitable noise intensities. Inparticular, the percentage of insects which react to the sub-threshold signal,shows a non-monotonic behavior, characterized by the presence of a maximum, forincreasing levels of the noise intensity. This constructive interplay betweenexternal noise and calling signal is the signature of the non-dynamicalstochastic resonance phenomenon. Finally, we describe the behavioral activationstatistics by a soft threshold model which shows stochastic resonance. We findthat the maximum of the ensemble average of the input-output cross-correlationoccurs at a value of the noise intensity very close to that for which thebehavioral response has a maximum.
