“…Bending waves propagate dispersively along plants, meaning that propagation speed is frequencydependent [26]. Thus, fewer frequency components would mean smaller degradation of the signal's envelope during propagation, preserving information stored in the signal's time domain which is important for mate recognition [27,28].…”

Pentatomid bugs communicate using substrate-borne vibrational signals that are transmitted along herbaceous plant stems in the form of bending waves with a regular pattern of minimal and maximal amplitude values with distance. We tested the prediction that amplitude variation is caused by resonance, by measuring amplitude profiles of different vibrational pulses transmitted along the stem of a Cyperus alternifolius plant, and comparing their patterns with calculated spatial profiles of corresponding eigenfrequencies of a model system. The measured distance between nodes of the amplitude pattern for pulses with different frequencies matches the calculated values, confirming the prediction that resonance is indeed the cause of amplitude variation in the studied system. This confirmation is supported by the resonance profile obtained by a frequency sweep, which matches theoretical predictions of the eigenfrequencies of the studied system. Signal bandwidth influences the amount of amplitude variation. The effect of both parameters on signal propagation is discussed in the context of insect vibrational communication.

“…The continuous emission of the FCS enables the males to locate the females [36], [38], while the occasional emitting of their vibratory signals stimulates continuous emission of the FCS at a stable repetition rate [39]. The mean recorded durations for the FCS of the Slovenian population of N. viridula were 720±37 ms for the PD and 1912±93 ms for the ID [10]. The study [10] used behavioural tests to investigate the preference of the males for the temporal parameters of the FCS.…”

During mating, males and females of N. viridula (Heteroptera: Pentatomidae) produce sex- and species-specific calling and courtship substrate-borne vibratory signals, grouped into songs. Recognition and localization of these signals are fundamental for successful mating. The recognition is mainly based on the temporal pattern, i.e. the amplitude modulation, while the frequency spectrum of the signals usually only plays a minor role. We examined the temporal selectivity for vibratory signals in four types of ascending vibratory interneurons in N. viridula. Using intracellular recording and labelling technique, we analyzed the neurons' responses to 30 pulse duration/interval duration (PD/ID) combinations. Two response arrays were created for each neuron type, showing the intensity of the responses either as time-averaged spike counts or as peak instantaneous spike rates. The mean spike rate response arrays showed preference of the neurons for short PDs (below 600 ms) and no selectivity towards interval duration; while the peak spike rate response arrays exhibited either short PD/long ID selectivity or no selectivity at all. The long PD/short ID combinations elicited the weakest responses in all neurons tested. No response arrays showed the receiver preference for either constant period or duty cycle. The vibratory song pattern selectivity matched the PD of N. viridula male vibratory signals, thus pointing to temporal filtering for the conspecific vibratory signals already at level of the ascending interneurons. In some neurons the responses elicited by the vibratory stimuli were followed by distinct, regular oscillations of the membrane potential. The distance between the oscillation peaks matched the temporal structure of the male calling song, indicating a possible resonance based mechanism for signal recognition.

“…Each stimulatory sequence was composed from natural vibrational signals assembled by the use of the computer programme [20,36,37]. The natural sequence was recorded from the membrane of the low-middle frequency loudspeaker membrane (Conrad Electronic, impedance 8W, 4.5 mm diameter, 90-2000 Hz) with a laser vibrometer (controller 2200-L, sensor head OFV-353, Polytech, GmbH, Waldbronn, Germany) and stored in a computer using Sound Blaster Audigy 4 sound card (Creative Labs Inc.) and Cool Edit Pro 2 software at the sampling rate of 44100 Hz.…”
