“…On the other hand, the song repertoire of P.bidens contained one female and four different male songs whereas P. maculiventris females were silent and males produced just one song type by abdominal vibration [4]. Tremulatory signals of both species shared similar characteristics and were comparable with signals previously reported from male P. bidens [14].…”

“…Gogala [14] showed that the song repertoire of P. bidens includes additional songs besides the male rivalry song [15]. Furthermore, the different frequency spectra of vibratory signals of various species [14] indicate that different mechanisms are probably involved in vibratory signal production. We also predict that the apparent lack of chemical signalling [12] may be compensated for by a larger variety of other types of signals.…”

Predatory bug Picromerus bidens communicates at different frequency levels

The Asopinae (Heteroptera: Pentatomidae) are a subfamily of stinkbugs with predaceous feeding habits and poorly understood communication systems. In this study we recorded vibratory signals emitted by Picromerus bidens L. on a non-resonant substrate and investigated their frequency characteristics. Males and females produced signals by vibration of the abdomen and tremulation. The female and male songs produced by abdominal vibrations showed gender-specific time structure. There were no differences in the temporal patterns of male or female tremulatory signals. The signals produced by abdominal vibrations were emitted below 600 Hz whereas tremulatory signals had frequency ranges extending up to 4 kHz. Spectra of male vibratory signals produced by abdominal vibrations contained different peaks, each of which may be dominant within the same song sequence. Males alternated with each other during production of rivalry signals, using different dominant frequency levels. We show that the vibratory song repertoire of P. bidens is broader than those of other predatory stinkbugs that have been investigated. The emission of vibrational signals with different dominant frequencies but the same production mechanism has not yet been described in heteropteran insects, and may facilitate location of individual sources of vibration within a group.

“…To our knowledge, however, the treehopper is the first reported example of a resonance potentially being used for abdominal motion that generates vibrational signals. In lacewings and bugs, which are known to produce dorso-ventral abdominal vibrations, the evidence is that muscles are used to move the abdomen with every cycle (Amon and Čokl, 1990;Čokl, et al, 2005;Gogala, 2006;Čokl, 2008;Henry and Wells, 2015). The advantage to the treehopper of making use of the natural resonance of the abdomen is that it is almost certainly metabolically less costly to have one pair of muscles contract once every other cycle than it is to have two pairs of muscles (one to raise the abdomen and one to lower it) contracting with each cycle.…”

This study is a physiological, anatomical and biophysical analysis of how plant-borne vibrational signals are produced by the treehopper Umbonia crassicornis. During courtship, males and females engage in a vibrational duet, with each producing a characteristic call. For males, this consists of a frequency-modulated tonal signal which is accompanied by rhythmic broad-band clicks. Although previous studies have described these complex signals in detail, little is known about how they are produced. By combining video recordings, electromyograms, dissections and mechanical modeling, we describe the mechanism by which the male produces his courtship signal. High-speed videos show that the tonal portion of the call is produced by periodic dorso-ventral movements of the abdomen, with a relatively large amplitude oscillation alternating with a smaller oscillation. Electromyograms from the muscles we identified that produce this motion reveal that they fire at half the frequency of the abdominal oscillation, throughout the frequency modulation of the tonal signal. Adding weight to the abdomen of a calling male reduces the frequency of motion, demonstrating that the abdominal motion is strongly influenced by its mechanical resonance. A mathematical model accounting for this resonance provides excellent qualitative agreement with measurements of both the muscle firing rate recorded electrophysiologically and the oscillatory motion of the abdomen as recorded in the high-speed video. The model, electromyograms and analysis of video recordings further suggest that the frequency modulation of the abdominal response is due to a simultaneous modulation in the muscle firing rate and a fluctuation in stiffness of the abdominal attachment.

“…In most other species of Pentatominae, such as Nezara viridula [21], Acrosternum impicticorne, Euschistus heros, Thyanta perditor [22], Thyanta pallidovirens [23], Holcostethus strictus [24], and Edessa meditabunda [25], the song type emitted by males in the calling phase also consists of regularly repeated pulses with a simple amplitude envelope (similar to the MS-1), while close-range courtship in later phases involves more elaborate signals with extensive amplitude modulation (similar to the MS-2), which is assumed to convey species specificity [5,26]. However, this is not a strict rule since an opposite phenomenon was described in Acrosternum hilare males [19].…”

Palomena prasina is interesting for the study of vibrational communication within the Pentatomid subfamily Pentatominae, because its host range is limited to woody plants, unlike the better known Nezara viridula, whose vibrational communication is commonly used as a model for the whole family. The vibrational repertoire of P. prasina was described several decades ago and is redescribed in this paper using modern methods for non-contact vibration recording. Additionally, we hypothesized that this species has retained the capacity for signal frequency variation necessary for tuning to resonance properties of various host plants of Pentatominae, but if the signals are emited in the absence of mechanical feedback, they are tuned more specifically to their native acoustic environment — woody plants. By recording live bugs signalling on different substrates and comparing spectral properties of their signals among substrates, we found that there is a match between the signals emitted on a woody branch and those emitted on a non-resonant surface, while spectral properties of signals emitted on herbaceous plants differ. Our findings provide evidence in support of the signal tuning hypothesis and shed further light on the crucial role of substrate in vibrational communication of insects.
