Abstract:

The Ducetia japonica species group consists of 11 species widely distributed in Asia and Australia. It includes a single species from the Philippines: Ducetia adspersa Brunner von Wattenwyl, 1878. Previously synonymized under Ducetia japonica (Thunberg, 1815), this species was resurrected for its unique stridulatory file. Based on its distinct stridulatory file morphology, male calling song and cytochrome c oxidase subunit I signature, we discovered and describe here a new species from Mindanao in the south of the Philippines: Ducetia laniae sp. nov. We also describe the calling song of this n

Abstract:

Abstract In acoustically communicating bushcrickets (Orthoptera: Tettigoniidae), most signal properties are influenced by the dimensions of the stridulatory apparatus, which in turn reflects body size and condition of the signaller. Females can assess male quality based on acoustic signals, suggesting that male stridulatory structures may be under sexual selection. We investigated scaling relationships between stridulatory structures, body size and body mass in males of the bushcricket Poecilimon veluchianus veluchianus, in comparison to the congeneric Poecilimon ampliatus.

Morphological characters bring the new species close to C. angulatus Tarbinsky, 1927 and C. karelini (Uvarov, 1910): the morphology of tegmina is similar to that in C. karelini, whereas the morphology of stridulatory file is similar to that in C. angulatus. In the new species and in C. angulatus, we found a homology of stridulatory pegs in two sexes, which is not common within Gomphocerinae. The song analysis allows to reliably distinguish all three species mentioned. At the same

Abstract:

The morphology of the stridulatory organ of the tropical bushcricket Hexacentrus unicolor is described and an investigation is made of stridulatory movements and muscle activities. 1. The song is produced by extremely fast stridulatory movements (320–415 Hz), during which, while closing the wings, a highly specialized file is brought into contact with the plectrum to produce sound. The muscles are activated with the same frequency, i.e. they work synchronously (neurogenic). 2. A few minutes before the stridulation starts, the muscles are activated in a similar rhythm to that pertaining during

Broad-frequency modulations in the calling songs of two cricket species (Eneoptera guyanensis and Lerneca fuscipennis) are documented. Such modulations were considered improbable in cricket songs, owing to the functioning mode of the cricket stridulum. Some species were known to emit sounds at frequencies that differed according to ambient temperature (thermometer crickets (Oecanthus spp.) among others), and small frequency modulations usually occur in the calling songs of many species at the beginning and at the end of each acoustic pulse.

Abstract:

Cricket songs are produced by a file–scraper mechanism, present only on the modified forewings of males, which causes a thickened membrane on each wing (the harp) to resonate and radiate sound. We examined the pattern of phenotypic variation and covariation in male body size, file tooth number, and harp area in decorated crickets, Gryllodes sigillatus, and obtained preliminary estimates of the additive genetic variance underlying these traits. Male body mass and harp area were positively correlated, and neither trait showed any appreciable evidence of genetic variance. We attribute the lack of

The acoustic communication system (ACS) in bark beetles has been studied mainly in species of the genera Dendroctonus, Ips and Polygraphus. Specifically, ACS of the roundheaded pine beetle, Dendroctonus adjunctus, has been little studied.

The new species differs from the other species on the genus in the phallic sclerites, presence of developed eyes (with ommatidia), pigmented integument, and the presence of stridulatory file on the tegmina.

Abstract:

Among insects, Orthoptera are a group famous for communicating by sound. This is especially true for bush-crickets (or katydids; Tettigonioidea). All acoustically active species produce sound by rubbing the fore wings (tegmina) against each other, using a stridulatory file situated on the lower side of the left tegmen and a scraper formed by the inner edge of the right tegmen (see e.g., Ragge & Reynolds 1998). Bush-cricket species of the tribe Acrometopini often have complicated stridulatory files and also complex songs, as shown in a recent study (Hemp et al. 2017). During the preparation

Abstract:

Male crickets, Cycloptiloides canariensis (body length 5 mm), stridulate with their forewings, which are hidden during rest under the large shield-like pronotum. The wings are opened into the stridulatory position by bending the body between the pro- and mesothorax. The song is a 2 s trill composed on average of 260 pulses (syllables) with a carrier frequency of about 6 kHz. The sound-emitting structures on the wings have been studied by laser vibrometry and particle dusting. A distinct membrane area, which includes a prominent mirror cell, acts as a resonator, amplifying the fundamental carri

Abstract:

The males of Mexican katydids Nesoecia nigrispina (Stal, 1873) produce calling songs and protest sounds using the typical stridulatory apparatus, situated, as in most of the other Ensifera, at the bases of the tegmina. It includes a stridulatory file on the upper tegmen and a plectrum on the lower one. The calling sounds, which are of two types (fast and slow), are two-syllabic series, with a repetition rate fluctuate within 3–4.5 s−1 (fast) and 1.2–2 s−1 (slow). After tactile stimulation, males produce protest signals in the form of short trills of uniform syllable duration. The syllable repe

During some recent expeditions in the Central African Republic and Ivory Coast it was possible to put together an abundant amount of specimens.
