...Alan T. Marshall; Peta L. Clode SUMMARY Elemental imaging by X-ray microanalysis of fully frozen-hydrated samples shows that when Malpighian tubules of the black field cricket( Teleogryllus oceanicus L.) are incubated in saline in which Rb + has been substituted for K + , Rb + replaces much...

...H. C. Bennet-Clark SUMMARY The anatomy and mechanics of the fore-wings of the Australian cricket Teleogryllus oceanicus were examined to study how resonances of the wings were excited, to model the interactions between the two wings during sound production, to account for the frequency changes...

...Jeff E. Engel; Ronald R. Hoy ABSTRACT The ultrasound acoustic startle response (ASR) of crickets ( Teleogryllus oceanicus ) is a defense against echolocating bats. The ASR to a test pulse can be habituated by a train of ultrasound prepulses. We found that this conditioning paradigm modified both...

...Gerald S. Pollack; Zen Faulkes ABSTRACT Teleogryllus oceanicus is particularly sensitive to two ranges of sound frequency, one corresponding to intraspecific acoustical signals (4–5 kHz) and the other to the echolocation cries of bats (25–50 kHz). We recorded summed responses of the auditory nerve...

... and elevation. Crickets ( Teleogryllus oceanicus ) were able to discriminate between sources separated by 11.25 ° (1/32 of a circle) in azimuth directly ahead of them; acuity declined to 45 ° in azimuth for sound sources 90 ° to the side and then improved to 33.75 ° at the rear. Crickets were also able...

...Carol I. Miles; Michael L. May; Eric H. Holbrook; Ronald R. Hoy ABSTRACT Tethered, flying Australian field crickets ( Teleogryllus oceanicus ) stimulated with ultrasound respond with a rapid, short-latency turn from the sound source. We analyzed the kinematics of two behavioral components...
