1. Campaniform sensilla are distributed across the body surface of many insects. 2. Both antennae have a subcone and three apical sensilla that resemble a spinule. 3.

Specifically the process is as follows : first the odorant wafts towards an insects antenna or sensilla . 6. Further detailed examination of the odor response at the olfactory sensory level can be done by sensilla recording. 7. 1 ) Male antennae are enlarged and contain elongated sensilla ( sensory organules ) not present in females. 8. Campaniform sensilla are cap-shaped protrusions located on the surface of the exoskeleton ( cuticle ) of insects. 9. Chordotonal organs detect and transmit distortions in their position / shape in the same way that campaniform sensilla do. 10.
