Substrate-borne vibrational communication is a common mode of information transfer in many invertebrate groups, with vibration serving as both primary and secondary signal channels in Orthopterans. The Cook Strait giant weta, Deinacrida rugosa (Orthoptera: Anostostomatidae), is an endangered New Zealand insect whose communication system has not been previously described. After field observations of intraspecific interactions in D. rugosa provided preliminary evidence for substrate-borne vibrational communication in the species, we sought to identify the following: vibrational signal structure, the mechanism of signal production, whether signal production is a sexually dimorphic trait, whether substrate-borne signals encode information regarding sender size, the primary social context in which vibration is utilized and finally, the function of vibrational signaling in the species. We used laser Doppler vibrometry to show that D. rugosa males produce low frequency (DF = 37.00 ± 1.63 Hz) substrate-borne vibrations through dorso-ventral tremulation. Rarely produced by females, male signals appear to target rivals while both are in the direct physical presence of a female. Tremulatory responses to playbacks were only produced by males in male-male-female trial contexts, and neither sex exhibited walking vibrotaxis to playback signals, indicating that substrate-borne vibrational signals are not likely a component of the courtship repertoire. While we found that vibrational signal structure was not closely related to signaler size, males that initiated male-male signaling bouts held a significant advantage in contests.

Within this Order, the superfamily Psylloidea is a diverse taxon which uses this type of signal modality during mating behavior between the two sexes. This study describes and compares the previously unreported vibrational communication of two closely related species of Macrohomotoma (Homotomidae). Both genders of these two species, Macrohomotoma gladiata Kuwayama 1908 and Macrohomotoma robusta Yang 1984, emit vibrational signals and establish duets during mating. The structure of male calling consists of two chirps while the female response is a single chirp. Males may sometimes follow the female response by emitting a single chirp that sounds similar to the female response with respect to the chirp duration and dominant frequency. This behavior is novel among Psylloidea and its potential function is discussed. Specific comparison of signal characteristics has revealed that the two species of Macrohomotoma are clearly distinguishable from each other which opens the possibility of acoustic signals being used for species delineation.10aduet10aHomotomidae10aMacrohomotoma10asubstrate-borne signal1 aLiao, Yi-Chang1 aYang, Man-Miao uhttp://link.springer.com/10.1007/s10905-017-9640-200585nas a2200157 4500008004100000022001400041245015000055210006900205260001600274300001400290490000700304100002000311700002100331700002000352856005500372 2006 eng d a0892-755300aVisual Communication Behaviour as a Mechanism Behind Reproductive Interference in Three Pygmy Grasshoppers (Genus Tetrix, Tetrigidae, Orthoptera)0 aVisual Communication Behaviour as a Mechanism Behind Reproductiv cSep-11-2007 a559 - 5710 v191 aHochkirch, Axel1 aDeppermann, Jana1 aGröning, Julia uhttp://link.springer.com/10.1007/s10905-006-9043-201425nas a2200157 4500008004100000022001400041245011400055210006900169260001600238300001200254490000600266520090000272100002401172700002301196856004801219 1991 eng d a0892-755300aMale-male behavior and sexual dimorphism of the ear of a zaprochiline tettigoniid (Orthoptera: Tettigoniidae)0 aMalemale behavior and sexual dimorphism of the ear of a zaprochi cJan-01-1991 a51 - 650 v43 a

The external anatomy of the auditory system of an undescribed zaprochiline tettigoniid (Genus nov. 22 Sp. 1, Australian National Insect Collection, Canberra) shows sexual dimorphism: the male appears to have no auditory spiracle equivalent to that seen in the female. Nocturnally active males aggregate around female required nectar sources in a random manner with regard to each other. There is limited evidence, either from song interaction or from their behavior in the field, that males respond to each other by acoustic cues. Laboratory trials, testing male phonotaxis, showed that movement was random with respect to a target group of caged calling males. In the field, the only signs of agonistic behavior consisted of an increased calling rate when males were close together. Taken together, these data suggest that the male may not preceive sound in the same way as the female.

The vibrational communication of Macrolophus is more complex than in other mirids, with a signal repertoire composed of two elements, only produced by males, while the females are mute. The "yelp" signal consists of one or several consecutive brief pulses with harmonic structure and is commonly produced by stationary males before mating, as a key-element of courtship. "Yelping" is also associated with contacts between males. The "roar" signal differs from "yelps" in that it has a broadband frequency pattern, a longer and more variable duration than "yelping", and is produced by males in association with walking on the leaf. Playback experiments did not affect male vibration emission, but when "roaring" was used as stimulus, it elicited a significant increase in the time spent walking. We detected significant differences between M. costalis and M. pygmaeus in some spectral parameters of the "roar" and "yelp" signals, so these signals could contain species-specific information. We conclude that "roaring" and "yelping" vibrational signals are used by Macrolophus in social communication, in particular in the context of mating behavior.1 aGemeno, César1 aBaldo, Giordana1 aNieri, Rachele1 aValls, Joan1 aAlomar, Oscar1 aMazzoni, Valerio uhttp://link.springer.com/10.1007/s10905-015-9518-0
