Structure and distribution of tactile and bimodal taste/tactile sensilla on the ovipositor, tarsi and antennae of the flour moth, Ephestia kuehniella (Zeller) (Lepidoptera : Pyralidae)

摘要: Abstract The bimodal taste/tactile sensilla on ovipositor, tarsi and antennae the tactile ovipositor of flour moth, Ephestia kuehniella (Zeller) (Lepidoptera : Pyralidae), were studied with electron microscopy to provide a structural base for further physiological behavioural studies. These can be involved in perception oviposition-deterring pheromone secreted by larvae, as well general assessment oviposition site. 3 different positions have slightly divergent morphological characteristics; tarsi, there are 4 chemosensory neurons, while 5. There is also mechano-sensory unit connected bristle these sensilla. Tactile sensilla, innervated one sensory cell, present 2 ovipositor. Freeze-substitution technique transmission was employed yielded superior results compared conventional chemical fixation.
