Species in subfamily Lipotactinae are brachypterous with a small body and have limited dispersal ability. In this study, it’s the first time to describe the male calling song of Lipotactes truncatus Shi & Li, 2009. MaxEnt was used to predict the potential geographic distribution of Lipotactinae in present-day and year 2070, to explore responses to global warming of this subfamily in China. As for L. truncatus, two types of calling songs are observed with peak frequencies in the ultrasound range. With the trend of global warming, the suitable habitats of subfamily Lipotactinae will change in three ways: i) migrate to high latitude area; ii) migrate to the coastal region of south China; iii) migrate along altitude gradients in mountains. Some species will be locked into the “sky islands”, which will accelerate speciation process, with global warming.

Insects have evolved a great diversity of sound-producing mechanisms largely attributable to their hardened exoskeleton, which can be rubbed, vibrated or tapped against different substrates to produce acoustic signals. However, sound production by forced air, while common in vertebrates, is poorly understood in insects. We report on a caterpillar that ‘vocalizes’ by forcing air into and out of its gut. When disturbed, larvae of the Nessus sphinx hawkmoth (Sphingidae: Amphion floridensis) produce sound trains comprising a stereotyped pattern of long (370 ms) followed by multiple short-duration (23 ms) units. Sounds are emitted from the oral cavity, as confirmed by close-up videos and comparing sound amplitudes at different body regions. Numerical models using measurements of the caterpillar foregut were constructed to test hypotheses explaining sound production. We propose that sound is generated by ring vortices created as air flows through the orifice between two foregut chambers (crop and oesophagus), a mechanism analogous to a whistling kettle. As air flows past the orifice, certain sound frequencies are amplified by a Helmholtz resonator effect of the oesophagus chamber. Long sound units occur during inflation, while short sound units occur during deflation. Several other insects have been reported to produce sounds by forced air, but the aeroacoustic mechanisms of such sounds remain elusive. Our results provide evidence for this mechanism by showing that caterpillars employ mechanisms similar to rocket engines to produce sounds.

The ecological preferences and bioacoustics of bush-crickets, crickets and grasshoppers species were studied in middle and lower Prut River basin, a research conducted in 55 localities from Romania and 33 localities in the Republic of Moldova. A total number of 91 species of Orthoptera were collected in the study area: 85 species encountered on the western side of Prut River basin (9 Phaneropteridae, 24 Tettigoniidae, 1 Bradyporidae, 5 Gryllidae, 1 Gryllotalpidae, 1 Tridactylidae, 5 Tetrigidae, 39 Acrididae) and 76 species found on the eastern side (7 Phaneropteridae, 19 Tettigoniidae, 1 Bradyporidae, 5 Gryllidae, 1 Gryllotalpidae, 1 Tridactylidae, 3 Tetrigidae, 39 Acrididae). Four species are recorded for the first time in the Orthoptera fauna of the Republic of Moldova: Barbitistes constrictus (Fabricius), Poecilimon fussii Brunner von Wattenwyl, Metrioptera roeselii fedtschenkoi (Saussure) and Pholidoptera frivaldskyi (Herman).

For most insects, size determines the call frequency. This paper describes the acoustics of a small brachypterous cricket (Rufocephalus sp.; body length 9.6 mm) producing a call with a carrier frequency of approximately 3.2 kHz from a subterranean burrow. Crickets such as Gryllus campestris are approximately twice this length and produce a call frequency close to 5 kHz. The burrow of Rufocephalus opens via a small hole with a diameter of 3.2 mm. The neck of the hole at approximately 1.4 mm depth opens to a vertical two-part burrow with an upper vase-shaped chamber 16.1 mm in height with a diameter of 9.4 mm. This top chamber connects via a 6.4mm high (diameter 5.2 mm) neck to a more irregular chamber approximately 18 mm high with a width of approximately 11 mm. The walls of the top chamber neck and of the upper part of the lower chamber are smooth and appear to be sealed with saliva. The song has a mean centre frequency of 3.2 kHz and is made up of variable-length trills of pulses of mean duration 15.8 ms. Many song pulses had smooth envelopes and their frequency did not vary by more than +/-40Hz from the centre frequency, with a relative bandwidth Q-3dB of over 50. Other pulses showed considerable amplitude and frequency modulation within the pulse. When driven by external sound, burrows resonated at a mean frequency of 3.5 kHz with a mean quality factor Q of 7.4. Natural-size model burrows resonated at similar frequencies with similar Q values. One cricket, which had previously called from its own burrow at 2.95 kHz, sang at 3.27 kHz from a burrow that resonated at the same frequency. Life-size model burrows driven by external sound resonated at similar frequencies to the actual burrows; models three times life size resonated at one-third of this frequency. In all models, the sound pressure was more-or-less constant throughout the top chamber but fell rapidly in the neck of the burrow; the phase of the sound was effectively constant in the top chamber and neck and fell through approximately 180 degrees in passing from the neck into the lower chamber. A numerical model of the sound flow from region to region gave essentially similar results. A resonant electrical model fed from a high-impedance source with discrete tone bursts at different frequencies showed similar amplitude and frequency modulation to the various types of song pulses that were observed. It is suggested that the high purity of the songs results from close entrainment of the sound-producing mechanism of the insect's wings to the sharply resonant burrow.

Recordings were compared of the male calling songs and analysis performed of selected acoustic variables. This analysis is combined with sequencing of mtDNA - COI and examination of morphological traits to perform cluster analyses. The trees constructed from different datasets were structurally similar, bisecting the six geographical populations studied. Based on two large branches in the analysis, the species Gampsocleis sedakovii was partitioned into two subspecies, Gampsocleis sedakovii sedakovii (Fischer von Waldheim, 1846) and Gampsocleis sedakovii obscura (Walker, 1869). Comparing all the traits, the individual of Elunchun (ELC) was the intermediate type in this species according to the acoustic, genetic, and morphological characteristics. This study provides evidence for insect acoustic signal divergence and the process of subspeciation.10aacoustics10agene10ainterim morphs10amorphology10asubspecies1 aZhang, Xue1 aWen, Ming1 aLi, Junjiain1 aZhu, Hui1 aWang, Yinliang1 aRen, Bing-Zhong uhttp://zookeys.pensoft.net/articles.php?id=604302436nas a2200217 4500008004100000022001400041245010700055210006900162260001600231300001200247490000700259520175500266653001402021653001202035653001202047653001602059653001102075653001702086100002402103856009102127 2007 eng d a1082-646700aSound generation in Mantis religiosa (Mantodea: Mantidae): stridulatory structures and acoustic signal0 aSound generation in Mantis religiosa Mantodea Mantidae stridulat cJan-06-2007 a35 - 490 v163 a

Several species of mantids perform defensive displays during close-range encounters with predators. In adult Mantis religiosa, this display entails both visual and acoustic components, the latter being abdominoalary stridulation. Stridulatory modifications of the abdomen and hindwings and acoustic properties of the defensive sounds of M. religiosa are characterized here for the first time. Defensive sounds are generated via an abdominoalary mechanism involving contact between teeth found on the longitudinal veins of the metathoracic wings and pegs located on the abdominal pleura. Defensive stridulation in M. religiosa is highly variable in both spectral and time domains. Inter-individual variability may be stochastically greater than intra-individual variability for at least one acoustic parameter (peak frequency). The loudest portion of a sound emission (syllable), or down-pulse, has an average duration of 195 ms and features an abrupt rise to maximum amplitude. Inter-syllabic intervals are irregular and rate of syllable production depends on a mantid's sex. The acoustic output of M. religiosa is nonresonant, broadband, and of relatively low intensity. A minor ultrasonic component may be present in the spectra of these mantids (particularly in males). The modal peak frequency range (4 kHz interval) is 8-12 kHz (mean range ∼7.4-9.4 kHz). Acoustic parameters which appear to vary between the sexes and/or among females at different reproductive stages, may be related to the sexual size dimorphism of this species and morphological constraints associated with egg-bearing. The acoustic output of M. religiosa is considered with reference to its intended receivers and plausible mechanisms of predator deterrence.

The Chorthippus biguttulus group includes a number of common European species that are difficult to distinguish morphologically but are easily recognized in the field by the distinctive calling songs of the males. These song-patterns have not previously been studied in Spain and as a result the Iberian members of the group have been misidentified in almost all the extensive Spanish literature on the ecology and cytogenetics of these insects. In this study the male calling songs of all six members of the group known from the Iberian Peninsula and North Africa are fully described and illustrated with oscillograms at several different speeds. The songs of the three species known only from Iberia or North Africa, jacobsi, yersini and marocanus, are fully described for the first time (marocanus is here raised in rank from subspecies). Notes on recognition, using both morphology and song, are given for each species, and two identification keys are provided, one based on morphology and the other on song. It is shown that the three species biguttulus, brunneus and mollis, previously believed to be widespread in Iberia, are absent from most of the peninsula.
