A Comparative Study of the Stridulatory Files of the British Gomphocerinae (Orthoptera: Acrididae)
Journal of Natural History, 1976Summary Samples of 20 specimens of each of the British species of Gomphocerinae were used as the basis of a comparative study of their stridulatory files. Although agreeing in general with earlier studies based on German samples, the British samples were found to have shorter files (both absolutely and in relation to the length of the hind femur) with ...

Variation in sperm precedence in Chorthippus grasshoppers (Caelifera: Gomphocerinae)
Physiological Entomology, 2000Summary Variation in the proportions of offspring fathered by a second male to mate (the P 2 value) has been studied in two species of grasshoppers, Chorthippus parallelus (Zetterstedt) and Ch. biguttulus

Subfamilies Acridinae, Gomphocerinae and Oedipodinae Are “Fuzzy Sets”: A Proposal for a Common African Origin [PDF]
Journal of Orthoptera Research, 2011 Abstract We propose that subfamilies Acridinae (including Truxalinae), Gomphocerinae and Oedipodinae are not monophyletic, and that, as a collective, originated in Africa some time before 100 mya. Our conclusions are based on a phylogenetic analysis of portions of 5 mitochondrial genes, totalling up to about 2.7 kilobase pairs, in 117 species collected

Australian Journal of Zoology, 1972
Communicative behaviour of nine species of Australian grasshoppers (seven Oedipodinae and two Gomphocerinae) is described and compared to North American and European species. Most signal types are represented in all three continents. Most similarities between the three groups are probably due to the retention of characteristics present in common ...

Journal of Comparative Physiology A, 1996
In the female grasshopper Gomphocerus rufus mating elicits 'secondary defense' which makes remating impossible. The behavioral change is caused by the liquid white secretions, proteins of less than 90 kD, which are produced by the white tubuli of the male's accessory glands.

In two populations of Chorthippus brunneus in the Breckland district of East Anglia an additional instar is interposed between instars II and III during the development of female nymphs. The IIa nymph occurs with a frequency approaching 100%, in both heavily and very lightly grazed grasslands.

Chorthippus bornhalmi in the heart of the Balkans (Acrididae: Gomphocerinae)
Articulata (Erlangen), 2015New records of Chorthippus bornhalmi in the Balkans are presented. The grasshopper is reported from 7 localities from the protected landscape of Vlasina in SE Serbia, representing the first records for Serbia. The new records of the species are discussed and bioacoustical information and general distribution is presented.

Sound production inParapellopedon instabilis(Rehn, 1906) (Orthoptera: Gomphocerinae)
Annales de la Société entomologique de France (N.S.), 2003Abstract The sounds produced by Parapellopedon instabilis (Rehn, 1906), are described for the first time on the basis of recordings made, in captivity, with an analogical tape recorder. The signals were digitized in the laboratory and analyzed using a software.
