Localization of bursicon in CCAP immunoreactive cells in the thoracic ganglia of the cricket Gryllus bimaculatus
... Our present study shows that, in Gryllus bimaculatus, bursicon activity is found mostly in the antero-lateral parts of TG1 and TG2, not in the postero-lateral parts. Immunostaining of these two thoracic ...

Kinematics of phonotactic steering in the walking cricket Gryllus bimaculatus (de Geer)
... Female crickets, Gryllus bimaculatus , are attracted by the male calling song and approach singing males; a behaviour known as phonotaxis. Even tethered females walking on a trackball steer towards a ...

Notch/Delta signalling is not required for segment generation in the basally branching insect Gryllus bimaculatus
... Arthropods and vertebrates display a segmental body organisation along all or part of the anterior-posterior axis. Whether this reflects a shared, ancestral developmental genetic mechanism for segmentation is uncertain. ...

Ancestral functions of Delta/Notch signaling in the formation of body and leg segments in the cricket Gryllus bimaculatus
... To examine the functions of Gb ⬘ Delta and Gb ⬘ Notch in the formation of body and leg segments, we injected dsRNA directed against these genes into adult females to determine knockdown Fig. 3. Expression patterns of ...

Phase shifts in binaural stimuli provide directional cues for sound localisation in the field cricket Gryllus bimaculatus
... The cricket’s auditory system is a highly directional pressure difference receiver whose function is hypothesised to depend on phase relationships between the sound waves propagating through the auditory trachea that ...

The effect of an initial high-quality feeding regime on the survival of Gryllus bimaculatus (black cricket) on bio-waste
... Previous studies have led to claims that insects can offer a solution to several food security hurdles, one of which is the processing of food waste. However, although it has been demonstrated that some insects survive ...
