Spectral Sensitivity Studies on the Visual System of the Praying Mantis, Tenodera sinensis
In these studies a constant ERG response was used as a measure of visual sensitivity to different wavelengths of light. The dark-adapted compound eye of Tenodera sinensis is dominated by a single class of photoreceptors. with a major peak of sensitivity at about 510-520 nm, and with a minor peak of sensitivity in the near-ultraviolet region at about 370 nm. The dark-adapted dorsal ocellus does ...
متن کاملPrey capture in the praying mantis Tenodera aridifolia sinensis: coordination of the capture sequence and strike movements.
Coordination of the complete capture sequence of the praying mantis has been studied in detail using several specially developed photographic techniques. The mantis was able to attack prey throughout a large three-dimensional capture zone by changing body orientation relative to its perch. This orientation centred prey on the median plane and brought it within an attack zone relative to the pro...
متن کاملAntennal Development in the Praying Mantis (Tenodera aridifolia) Highlights Multitudinous Processes in Hemimetabolous Insect Species
Insects possess antennae equipped with a large number of segments (flagellomeres) on which sensory organs (sensilla) are located. Hemimetabolous insects grow by molting until they reach adulthood. In these species, the sensory structures develop and mature during each stage of development; new flagellomeres are generated at each molt elongating the antennae, and new sensilla appear. The praying...
متن کاملRole of a looming-sensitive neuron in triggering the defense behavior of the praying mantis Tenodera aridifolia.
In responses to looming objects, the praying mantis shows a defense behavior, which consists of retracting forelegs under the prothorax. The role of a looming-sensitive neuron in triggering this behavior was investigated by simultaneously recording the activity and behavioral responses of the neuron. The mantis initiated the defense behavior earlier in response to larger and slower looming stim...
متن کاملBinocular Spatial Localization in the Praying Mantis
The way in which mantids localize the direction and the distance of their prey has been analysed, to clarify the importance of binocular interactions. The results suggest the following major points: 1. Binocular interactions coordinate monocular directional information, such that the direction in which a mantid fixates its prey is intermediate between the image directions in the two eyes (Figs ...
