Sense organs of a thysanuran,Ctenolepisma lineata pilifera, with special reference to those on the antennal flagellum (Thysanura, Lepismatidae)

摘要: Six types of sense organs are present on the antennal flagellum Ctenolepisma lineata pilifera: tactile hairs, trichobothria, thick-walled chemoreceptors, small thin-walled chemoreceptors and coeloconic chemoreceptors. The number, size distribution antenna each type have been recorded. base hair is more complex than that other insects examined earlier. Trichobothria, long, slender hairs oscillate in a gentle puff air, an unusal feature especially so for antenna. two differ shape, structure their walls internal parts. A pocket-like depression floor cavity which peg organ set has not found earlier studies. Its function unknown. The axons from sensory neurons extend along inner surface epidermis as sheet fibers lining lumen. Near pedicel leave join to form nerve. A few observations appendages antennae some notes behavior included.
