Species Recognition During Substrate-Borne Communication in Nezara viridula (L.) (Pentatomidae: Heteroptera)
摘要：
The information code in the temporal and spectral characteristics of the substrate-borne communication signals produced by insects has been primarily studied in insects in the suborder Auchenorrhyncha. In the present study we investigated which of the female calling song (FCS) parameters in Nezara viridula (L.) (Heteroptera, Pentatomidae) are essential for recognition by conspecific males. In playback experiments we measured male vibrational responsiveness to FCS signals varying in the durations of pulse trains and inter-pulse train intervals, repetition times, duty cycles, and dominant frequencies, and determined the preference range for each specific parameter. Males were able to distinguish songs of different temporal and frequency parameters and responded best to values characteristic of the song of conspecific females. Signal recognition is achieved on the basis of two temporal filters tuned to the durations of the pulse train and inter-pulse train interval. Males responded best to the dominant frequency characteristic of conspecific songs, which are tuned to the resonant properties of the herbaceous plants used for intraspecific signal transmission during communication.
