... important to compare phylogenetically related species with different investments in flight capability. Here, we describe and compare morphological and electrophysiological properties of photoreceptors from the habitually flying green cockroach Panchlora nivea and the American cockroach Periplaneta americana...

... cockroaches Periplaneta americana use their antennae to mediate escape running by tracking vertical surfaces such as walls. A control theoretic model of wall following predicts that stable control is possible if the animal can compute wall position (P) and velocity, its derivative (D). Previous whole-nerve...

... is a physical linkage mediating mechanical interactions between body and environment, mechanical tuning of the sensor is critical for effective control. We determined the open-loop dynamics of a tactile sensor, specifically the antenna of the American cockroach, Periplaneta americana , an animal that escapes...

... to elucidate the motion cycles of the mouthparts in the cockroach Periplaneta americana . Digital X-ray footage sequences were used in order to calculate pre-defined angles and distances, each representing characteristic aspects of the movement pattern. We were able to analyze the interactions of the mouthpart...

... the energy from movement to reconfigure a passive sensor. We investigated high-speed, antenna-mediated tactile navigation in the cockroach Periplaneta americana . We discovered that the passive antennal flagellum can assume two principal mechanical states, such that the tip is either projecting backward...

... compressa ) performs a delicate brain surgery on its prey (the American cockroach Periplaneta americana ) to take away its motivation to initiate locomotion. Following a brief background account of parasitoid wasps that manipulate host behaviour, we survey specific aspects of the unique effects...

...Lior Ann Rosenberg; Jose Gustavo Glusman; Frederic Libersat SUMMARY When stung by the parasitoid wasp Ampulex compressa , cockroaches Periplaneta americana enter a hypokinetic state that is characterized by little, if any, spontaneous locomotor activity. In the present study we investigate...

...Carsten Hille; Bernd Walz SUMMARY Cells of the dopaminergically innervated salivary ducts in the cockroach Periplaneta americana have a vacuolar-type H + -ATPase(V-ATPase) of unknown function in their apical membrane. We have studied whether dopamine affects intracellular pH (pH i ) in duct cells...

...N. J. Cowan; J. Lee; R. J. Full SUMMARY The American cockroach, Periplaneta americana , is reported to follow walls at a rate of up to 25 turns s –1 . During high-speed wall following, a cockroach holds its antenna relatively still at the base while the flagellum bends in response to upcoming...

P. americana males showed no preferred walking orientation when released in zero wind in the absence of pheromone. When introduced into 25 cm s -1 wind...

...Jiro Okada; Yoshihiro Toh SUMMARY To characterize the spatio-temporal patterns of antennal behavior in insects, the voluntary movement of both right and left antennae was examined in the cockroach Periplaneta americana . The position of the tip of the antenna (flagellum) is controlled by two mobile...
