The Song Relationships of Four Species of Ground Crickets (Orthoptera: Gryllidae: Nemobius)

'Suicide' of crickets harbouring hairworms: a proteomics investigation.

Despite increasing evidence of host phenotypic manipulation by parasites, the underlying mechanisms causing infected hosts to act in ways that benefit the parasite remain enigmatic in most cases. Here, we used proteomics tools to identify the biochemical alterations that occur in the head of the cricket Nemobius sylvestris when it is driven to water by the hairworm Paragordius tricuspidatus. We...

A new mute species of the genus Nemobius Serville (Orthoptera, Gryllidae, Nemobiinae) discovered in colluvial, stony debris in the Iberian Peninsula: A biological, phenological and biometric study.

Sampling of a Mesovoid Shallow Substratum (MSS) of a scree in the Guadarrama mountains (Madrid, Spain) revealed a population of crickets of the genus Nemobius Serville. A detailed morphological study revealed that the cricket was a new species, Nemobius interstitialis sp. nov., which is principally characterized by the absence of a tympanum in the outer margin of the foreleg tibiae and a peculi...

The terminal abdominal ganglion of the wood cricket Nemobius sylvestris.

The abdominal cerci of the wood cricket, Nemobius sylvestris, are covered by a variety of hair-like sensilla that differ in length, thickness, and articulation. Fillings from the cercal nerves with cobalt chloride and fluorescent dyes revealed the projection of sensory axons into the terminal abdominal ganglion of the ventral nerve chain. Two projection areas on each side of the terminal abdomi...

Local population density and the activation of movement in migratory band-forming Mormon crickets

The Mormon cricket, Anabrus simplex (Orthoptera: Tettigoniidae), is a flightless katydid that undergoes major outbreaks in western North America. Under outbreak conditions, Mormon crickets often form large cohesive migratory bands that can contain millions of individuals moving in unison across the landscape. Density-dependent phase polyphenism has been hypothesized as a behavioural mechanism u...
