House crickets (Othroptera: Gryllidae: <i>Acheta domesticus</i>) reared in small-scale laboratory conditions harbour limited viral flora

The neuromuscular mechanism of stridulation in crickets (Orthoptera: Gryllidae).

Study of the insect neuromuscular system appears very promising as a means of explaining behaviour in terms of cellular operation. The relatively small number of neurons, the ganglionic nature of the nervous system, the simplicity of the neuromuscular arrangement, and the repetitiveness of behavioural sequences all lend themselves to a solution of this problem. As a result, an increasing number...

Orientation to calling song by female crickets, Scapsipedus marginatus (Gryllidae).

How Dietary Phosphorus Availability during Development Influences Condition and Life History Traits of the Cricket, Acheta domesticas

Phosphorus is extremely limited in the environment, often being 10-20 times lower in plants than what invertebrate herbivores require. This mismatch between resource availability and resource need can profoundly influence herbivore life history traits and fitness. This study investigated how dietary phosphorus availability influenced invertebrate growth, development time, consumption, condition...

Contrasting the Chromosomal Organization of Repetitive DNAs in Two Gryllidae Crickets with Highly Divergent Karyotypes

A large percentage of eukaryotic genomes consist of repetitive DNA that plays an important role in the organization, size and evolution. In the case of crickets, chromosomal variability has been found using classical cytogenetics, but almost no information concerning the organization of their repetitive DNAs is available. To better understand the chromosomal organization and diversification of ...

Sound radiation and wing mechanics in stridulating field crickets (Orthoptera: Gryllidae).

Male field crickets emit pure-tone mating calls by rubbing their wings together. Acoustic radiation is produced by rapid oscillations of the wings, as the right wing (RW), bearing a file, is swept across the plectrum borne on the left wing (LW). Earlier work found the natural resonant frequency (f(o)) of individual wings to be different, but there is no consensus on the origin of these differen...
