20.500.12556/DiRROS-21685 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. substrate-borne vibrational communication signal production signal frequency variation true false true Angleški jezik Ni določen Neznano 2025-03-12 11:14:43 2025-03-12 11:14:43 2025-03-13 03:52:39 0000-00-00 00:00:00 2011 0 0 str. 431-439 no. 3 Vol. 6 2011 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2011-04-27 591 1895-104X 10.2478/s11535-011-0015-y 2350159 http://dx.doi.org/10.2478/s11535-011-0015-y 1 d2b55be3-ff2a-11ef-88ed-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=31090 RAZ_Cokl_Andrej_2011.pdf RAZ_Cokl_Andrej_2011.pdf 1 E18EE1BAA0BA19E4E8066234DF27D3BF 2f98705d7ad7287778dcb579a148ee66ca7d200bafce5734f3a662714c979dbf ef2791f8-ff2a-11ef-88ed-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=31091 Nacionalni inštitut za biologijo 0 0 0
