Locust flight
نویسنده
چکیده
Under certain environmental and population conditions some species (the locusts) of Acridid Orthoptera swarm and are capable of migrating hundreds of miles using flight as the primary means of locomotion. Locust flight is a behavior that lends itself to analysis from many approaches and that has attracted considerable research attention for many years. In particular the role of the nervous system in controlling locust flight behavior has been a focus of investigation since the middle of the twentieth century.

Locust flight is of interest to neurophysiologists as an example of simple repetitive behaviour easily observable in the laboratory and susceptible to single-unit analysis. Flight aerodynamics (Weis-Fogh, 1956), muscle activity patterns (Wilson, 1961; Wilson & Weis-Fogh, 1962) and sensory regulation (Wilson & Gettrup, 1963; Gettrup & Wilson, 1964; Gettrup, 1966) have been intensively examined. ...

Reconfiguration of the respiratory network at the onset of locust flight. J. Neurophysiol. 80: 3137-3147, 1998. The respiratory interneurons 377, 378, 379 and 576 were identified within the suboesophageal ganglion (SOG) of the locust. Intracellular stimulation of these neurons excited the auxillary muscle 59 (M59), a muscle that is involved in the control of thoracic pumping in the locust. Like...
متن کاملCentral modulatory neurons control fuel selection in flight muscle of migratory locust.
Insect flight is one of the most intense and energy-demanding physiological activities. High carbohydrate oxidation rates are necessary for take-off, but, to spare the limited carbohydrate reserves, long-distance flyers, such as locusts, soon switch to lipid as the main fuel. We demonstrate that before a flight, locust muscles are metabolically poised for take-off by the release of octopamine f...
متن کاملNeural correlates to flight-related density-dependent phase characteristics in locusts.
Locust phase polymorphism is an extreme example of behavioral plasticity; in response to changes in population density, locusts dramatically alter their behavior. These changes in behavior facilitate the appearance of various morphological and physiological phase characteristics. One of the principal behavioral changes is the more intense flight behavior and improved flight performance of grega...
