..., there is no information about the behavioural preferences of females over their complete adulthood. We analysed phonotaxis in female Gryllus bimaculatus throughout their entire adult lifetime and measured the impact of sound amplitude, carrier frequency and the temporal pattern of test songs on their auditory response...

...Tetsutaro Hiraguchi; Tsuneo Yamaguchi; Masakazu Takahata SUMMARY Mechanoreceptors involved in the escape jumping evoked by hindwing stimulation have been investigated in the field cricket Gryllus bimaculatus . By partial ablation of the hindwing, we found that a mechanosensory system relevant...

...Yukihisa Matsumoto; Makoto Mizunami SUMMARY Temporal determinants of olfactory long-term memory retention in the cricket Gryllus bimaculatus were studied. Elementary appetitive and aversive conditioning procedures, as well as a differential conditioning procedure, were applied. In appetitive...

...A. S. M. Saifullah; Kenji Tomioka SUMMARY The bilaterally paired optic lobe circadian pacemakers of the cricket Gryllus bimaculatus mutually exchange photic and circadian information to keep their activity synchronized. The information is mediated by a neural pathway, consisting of the so-called...

...Michael Gebhardt; Hans-Willi Honegger SUMMARY We investigated five different descending brain interneurons with dendritic arborizations in the deutocerebrum in the crickets Gryllus bimaculatus and G. campestris . These interneurones convey specific antennal mechanosensory information to the ventral...

... of copulation and spermatophore formation are now more fully understood. Crickets, Gryllus bimaculatus DeGeer, were used. They were reared in a plastic box (70 cm×40 cm×20 cm), fed a diet of insect pellets and water ad libitum and maintained on a 12 h:12 h light:dark photoperiod at 27 °C...

...B. Wenzel; B. Hedwig ABSTRACT Neuroactive substances were administered into the frontal protocerebrum of tethered male Gryllus bimaculatus by pressure injections from microcapillaries. All three types of species-specific song pattern (calling song, rivalry song and courtship song) could be elicited...

... correlations with walking cricket Gryllus bimaculatus Measuring electrophysiological events in animals behaving normally remains one of the most powerful techniques for unravelling the neural basis of behaviour. The strength of such investigations lies in uncovering neuronal events...

... Gryllus campestris and Gryllus bimaculatus ( Eibl and Huber, 1979 ) and the grasshopper Decticus verrucivorus ( Kalmring et al . 1978 ), the auditory organ (tympanal organ) neurones have been shown to project their axons to the ventral region of the mVAC. These facts suggest the possibility...

...R. O. Stephen; J. C. Hartley ABSTRACT The calls of male Gryllus bimaculatus were digitally recorded under four different conditions: in air; in 80 % He/20 % O 2 ; with the tympana occluded with wax in air and finally in the helium/oxygen mixture. The principal frequency component, usually referred...

...Eran Tauber; Jeffrey M. Camhi ABSTRACT The wind-evoked escape behavior of freely ranging crickets ( Gryllus bimaculatus ) was studied using high-speed video and film analysis. The escape response can be of three types: a turn, a jump or a turn + jump. Any of these can be followed by running...

...Tadashi Gomi; Takashi Okuda; Seiji Tanaka ABSTRACT The development and degeneration of the flight muscles in adult crickets, Gryllus bimaculatus , were studied (1) by determination of the total protein content, (2) by SDS one-dimensional polyacrylamide gel electrophoresis (SDS–PAGE) of muscle...
