Summary1.Normal Small Tortoiseshells tethered to a flight mill fly up to 5 h (Figs. 1,3). Following flagellar amputation (Fig. 2), flight speed increases significantly by about 30% (Fig. 4). Increased flight speed persists when the amputated flagella are attached to the frons (Fig. 5), but normal flight speed is restored when the amputated flagella are reattached to the proximal antennal stumps (Fig. 6).2.Progressive amputation of parts of the flagella results in successive increases in flight…

Summary1.In the Small Tortoiseshell (Aglais urticae L.), flying tethered on a flight balance in front of a wind tunnel (Fig. 1), different kinematic and aerodynamic flight variables were recorded

Antennal Mechanosensors Mediate Flight Control in Moths

It is shown that mechanosensory input from the antennae serves a similar role during flight in hawk moths, which are four-winged insects, and plays a crucial role in maintaining flight stability of moths.

Antennae in the hawkmoth Manduca sexta (Lepidoptera, Sphingidae) mediate abdominal flexion in response to mechanical stimuli

An abdominal flexion response mediated by the antennal mechanosensory input during mechanical body rotations is described, which can lead to a more stable behavioral output response when the animal is faced with turbulent perturbations to the flight path.

The roles of vision and antennal mechanoreception in hawkmoth flight control

Investigation of the visual-mechanosensory integration in an insect which lacks halteres shows the importance of antennal mechanosensors in providing rapid mechanOSensory feedback for finer control of flight manoeuvres, acting in parallel to visual feedback.

Antennal mechanosensors mediate sex pheromone‐induced upwind orientation in the potato tuberworm moth

The results of the present study indicate that males of P. operculella orient upwind in response to mechanoreceptive cues from mechanosensory organs on their antennae.

The neural mechanisms of antennal positioning in flying moths

The neural mechanisms of antennal positioning in hawk moths are described from behavioral, neuroanatomical and neurophysiological perspectives, showing that Böhm's bristles control antennals positioning in moths via a reflex mechanism.

The role of visual and mechanosensory cues in structuring forward flight in Drosophila melanogaster

It is shown that Drosophila melanogaster, magnetically tethered so as to be able to rotate about their yaw axis, are able to detect and orient into a wind, as would be experienced during forward flight.

Antennal Mechanosensory Neurons Mediate Wing Motor Reflexes in Flying Drosophila

These results are consistent with a model in which flying flies use JO neurons to detect increases in the wing-induced airflow and that JO neurons are involved in a response that decreases contralateral wing stoke amplitude.

Encoding properties of the mechanosensory neurons in the Johnston's organ of the hawk moth, Manduca sexta

The encoding properties of individual scolopidia from the Johnston's organs in the hawk moth, Manduca sexta, are characterized through intracellular neurophysiological recordings from axons of theScolopidial neurons to showcase the speed and high sensitivity of scolipidia of the Johnston’s organs, and hence their ability to encode fine antennal vibrations.

Wireless Stimulation of Antennal Muscles in Freely Flying Hawkmoths Leads to Flight Path Changes

It is shown that ultra-low-current electrical stimulation of antennal muscles in freely-flying hawkmoths leads to repeatable, transient changes in the animals' pitch angle, as well as less predictable changes in flight speed and flight altitude.

Findings suggest that in free flying locusts the air-current sense organs affect the flight speed in opposite ways: the hair patches stimulate it and the antennae reduce it, they being the sensory units of a negative feedback mechanism.

The antennae ofLocusta migratoria are passively turned aside by the air current and the 1st segment of the flagellum is bent up to 1 ° with respect to the pedicellus, and the wing-stroke frequency rises and the stroke angles and the frequency are negatively correlated.

The antennal movement apparatus in the small tortoiseshell (Aglais urticae L., Insecta, Lepidoptera)

The Johnston's organ, the Böhm's bristles and the antennal muscles are supplied by nerves which arise in the deutocerebrum, the sense cells of which can probably perceive passive movements of the flagellum in relation to the pedicel.

Aerodynamic and mechanical properties of the antennae as air-current sense organs inLocusta migratoria

The mechanical properties of the flagellum and its dynamic characteristics are analyzed which are both a prerequisite for the evaluation of the adequate stimulus for the pedicellar mechanoreceptors and their possible role in flight control.

An analysis is given of the aerodynamic and elastic properties of the mechanical system which transfers air current to act as stimulus on the mechanoreceptors in the antennae.

The Antennae of Insects as Air-Current Sense Organs and their Relationship to the Control of Flight

In insects, the cuticular sensilla are used for the perception of air currents and no single receptor of this type is, alone, an air-current sense organ but only one component of the more complex organ to which it belongs, for example, the antenna.

A Possible Genetic Explanation and Understanding of Migration of Continuous Brooded Insects

Observations of D. and E. Lack on a southerly migration of insects in October 1950 at Port de Gavarnie in the Pyrenees makes possible a hypothetical interpretation of migration on a genetic basis for the first time.

Under many meteorological conditions such patterns of air movement as roll vortices or internal gravity waves produce readily detectable updrafts capable of providing both lift and information about the direction of the wind or wind shear.
