20.500.12556/DiRROS-21672 Palomena prasina (Hemiptera: Pentatomidae) vibratory signals and their tuning with plant substrates 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. vibrational communication signal propagation frequency characteristics Pentatominae true false true Angleški jezik Latinski jezik Neznano 2025-03-12 10:15:58 2025-03-12 10:15:58 2025-03-13 03:52:37 0000-00-00 00:00:00 2013 0 0 str. 670-680 issue 7 Vol. 8 2013 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2013-04-23 591 1895-104X 10.2478/s11535-013-0188-z 2779215 http://dx.doi.org/10.2478/s11535-013-0188-z 1 9db46b51-ff22-11ef-88ed-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=31065 RAZ_Polajnar_Jernej_2013.pdf RAZ_Polajnar_Jernej_2013.pdf 1 B80A43E227699AC66D060C231BC03AC7 d4e71cd3dc447718fe353c2c68b04c57edf84c80eb8c9195a5d3246933d7f7ea bcf77e14-ff22-11ef-88ed-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=31066 Nacionalni inštitut za biologijo 0 0 0
