The calling songs of the Namibian armoured ground crickets Acanthoplus longipes and Acanthoproctus diadematus were analysed and described for the first time. Some differences in the length of the cuticular file and the number of the teeth of the pars stridens are also described. The different song patterns are related to differences in the autecology of the two species. Both utilise a broad frequency bandwidth, but the rare and endemic Acanthoproctus diadematus, which lives in interdunal areas… Expand
Temporal patterns of intra- and interspecific acoustic signals differ in two closely related species of Acanthoplus (Orthoptera: Tettigoniidae: Hetrodinae).
TLDR
The temporal patterns of the sounds were analysed in respect to species differences and song type differences and it was found that females of A. longipes perform phonotaxis only to songs with a species-specific temporal pattern, and that A. discoidales react positively to calling songs of both species.

Effects of temperature on the song parameters of the Moroccan bushcricket Eugaster spinulosa (Orthoptera, Tettigoniidae)
TLDR
The calling song of Eugaster spinulosa is broader in frequency than the song of other tettigoniids and shows a wide thermal plasticity, and it is found that an increase in temperature reduced the number of syllables per echeme. Expand
The acoustic communication system in six species of armoured ground crickets (Orthoptera: Tettigoniidae: Hetrodinae): Commonalities and species-specific differences
TLDR
The auditory communication system of the Hetrodinae species is similar to that of other Tettigoniids and exhibits species specific characters. Expand
Eco-Ethology and Trait Distribution of Two Congeneric Species – Different Strategies for the Pest Acanthoplus discoidalis and the Long-Legged A. Longipes (Orthoptera: Tettigoniidae)
High trait variability among insects reflects a combination of intra- and inter-phenotype variations. Our aim was to assess if the trait distribution of body measurements can be more significantlyExpand
Eco-ethology and trait distribution of two congeneric species – different strategies for the plague pest Acanthoplus discoidalis and the long-legged A. longipes (Orthoptera: Tettigoniidae)
TLDR
It is not primarily the body size that differentiates the two species, but rather the pronotum and hind leg larger sizes of A. longipes, a significant pest in African croplands, separate this pest from its congeneric species. Expand
Sounds, Behaviour, and Auditory Receptors of the Armoured Ground Cricket, Acanthoplus longipes
TLDR
The auditory sensory system of the taxon Hetrodinae has not been studied previously, and the frequency spectrum peaks at about 15 kHz in both types of sounds, whereas the hearing threshold has the greatest sensitivity between 4 and 10 kHz. Expand
Acoustic signals in katydids (Orthoptera, Tettigonidae). Communication I
Original and literature data on acoustic signals of katydids of the families Bradyporidae, Conocephalidae, Tettigoniidae, Phaneropteridae, Pseudophyllidae, Mecopodidae and Meconematidae are analyzed.Expand
Acoustic signals in katydids (Orthoptera, Tettigonidae). Communication 2
TLDR
Parallelisms and convergences are observed in the evolution of acoustic communication systems, but complex analysis allows revealing the initial type of the acoustic system and defining the reasons for adaptive reorganizations. Expand
Two functional types of attachment pads on a single foot in the Namibia bush cricket Acanthoproctus diadematus (Orthoptera: Tettigoniidae)
Insects have developed different structures to adhere to surfaces. Most common are smooth and hairy attachment pads, while nubby pads have also been described for representatives of Mantophasmatodea,Expand
Cytogenetics and molecular differentiation in the African armoured ground bushcrickets (Orthoptera: Tettigoniidae: Hetrodinae)
TLDR
The present work sets the stage for future experimental investigations of the phylogeny and systematics of this group of tettigoniid genera, and supported by Bayesian inference and maximum likelihood analysis. Expand

Some Observations on the Reproductive Behaviour of Acanthoplus Speiseri Brancsik (Orthoptera: Tettigoniidae: Hetrodinae)
TLDR
The courtship behaviour, orientations of members of a copulating pair relative to each other, copulation, spermatophore transfer from the male to the female during copulation and oviposition and postoviposition behaviours of the species are described. Expand
Calling songs of certain orthopteran species (Insecta, Orthoptera) in southern Portugal.
TLDR
These are the 12 first descriptions of the acoustic parameters and behaviour of the Portuguese populations of the 13 species occurring at the field station and which belong to the following genera: Conocephalus Thunberg, Tettigonia Linnaeus, Platycleis Fieber, Thyreonotus Serville and Uromenus Bolivar.

Male mate choice in the Botswana armoured ground cricket Acanthoplus discoidalis (Orthoptera: Tettigoniidae; Hetrodinae). Can, and how, do males judge female mating history?
TLDR
No difference in investment in any spermatophore characteristics between virgins and non-virgin females was found, but males do reject non-virgins more often and seem to prefer females of a lower mass, where higher mass may reflect increasing female age through advanced development of eggs. Expand
THE ENERGETIC COSTS OF CALLING IN THE BUSHCRICKET REQUENA VERTICALIS (ORTHOPTERA: TETTIGONIIDAE: LISTROSCELIDINAE)
TLDR
Call with relatively slow syllable rates may reduce the total cost of calling, and this may be a compensatory mechanism for their other high energetic cost of mating (a large spermatophylax). Expand
Behavioural adaptations of ground living bushcrickets to the properties of sound propagation in low grassland
TLDR
It can be concluded that the preferred biotope influences and creates behavioural patterns in Orthopterans, especially here in the two investigated species of bushcrickets Psorodonotus illyricus and Decticus verrucivorus. Expand

Insect hearing in the field
TLDR
The ability of the bushcricket to perceive the temporal characteristic of the call was tested with the auditory interneuron over increasing distances from a signaller and the temporal integrity of the song was found to be maintained over the whole broadcasting area. Expand
The acoustic behaviour of the bushcricket Tettigonia cantans II. Transmission of airborne-sound and vibration signals in the biotope
TLDR
The airborne-sound and the vibratory signals produced by stridulating Tettigonia cantans males, and the transmission of these signals in the natural biotope were investigated, providing a measure of the distance from the sound source. Expand

Size and scale effects as constraints in insect sound communication
TLDR
For optimal transfer of power to the surrounding medium, a sound source should have a radius of 1/6 to 1/4 of the sound wavelength, which enables long-range communication, but signal structure degrades with distance from the source. Expand
