... the development and scaling of body parts remains unclear. In bees, a reduction in body size and/or a reduction in body parts, such as the antennae, tongue and wings, and how they scale with body size (i.e. their allometry) could severely affect their fitness. To date, it remains unclear how temperature affects...

... signals that provide information about obstacles and predators. Here, we investigate how spontaneously walking crickets and crickets engaging in acoustically guided goal-directed navigation, i.e. phonotaxis, respond to mechanosensory stimuli detected by their long antennae. We monitored walking behaviour...

...Sushma Boppana; Julián F. Hillyer Mosquito antennae provide sensory input that modulates host-seeking, mating and oviposition behaviors. Thus, mosquitoes must ensure the efficient transport of molecules into and out of these appendages. To accomplish this, mosquitoes and other insects have evolved...

... showed that (1) the antennae are preferentially directed forward as animals run, and (2) nearly simultaneous contact with both antennae is required to make the cockroach stop. Our data indicate that running cockroaches employ strategies that set their sensorimotor systems in a mode of readiness to deal...

...Heidi Pye Henninger; Winsor H. Watson, III SUMMARY American lobsters produce carapace vibrations, which also lead to waterborne acoustic signals, by simultaneously contracting the antagonistic remotor and promotor muscles located at the base of the second antenna. These vibrations have a mean...

...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...

Examination of the mechanical responses of the antennal structures established that the distal antennal parts (the funiculus and the arista) together...

...J. Okada; Y. Toh SUMMARY Arthropods have hair plates that are clusters of mechanosensitive hairs, usually positioned close to joints, which function as proprioceptors for joint movement. We investigated how angular movements of the antenna of the cockroach ( Periplaneta americana ) are coded...

... activity was reduced during voluntary antennal movements. The reduction in activity occurred even after de-efferentation of the antenna, indicating that it had a central origin. Although we do not have experimental evidence for behavioural roles for the descending antennal mechanosensory interneurons...

When exposed to conspecific female sex pheromone, male B. mori flap their wings through a stroke angle of 90–110 ° at approximately 40 Hz without flying...

... antennal anatomy served as a sound-receiving structure. In the present study, the sound-induced vibrations of the antennal flagellum in male and female Aedes aegypti were compared, and the functional significance of the flagellar hairs for audition was examined. In both males and females, the antennae...

...J. M. Camhi; E. N. Johnson ABSTRACT Cockroaches ( Periplaneta americana ) use their antennae to detect a wall and to maintain a constant distance from it as they walk or run along it. The faster they run, the closer they position themselves to the wall. They also use their antennae to detect...

... during courtship. Antennal input is also crucial since antennectomized females show highly reduced levels of mounting. Immobilization of the scape–pedicel and pedicel–flagellum joints of female antennae had no effect on mounting probability, suggesting that mechanosensory input from chordotonal organs...
