A majority of the olfactory neurons on male antennae, housed within long trichoid sensilla, specifically respond to components of the female sex pheromone.
Sensilla counts have indicated that female antennae house an average of 630 trichoid sensilla while male antennae house an average of 225 trichoid sensilla [ 4, 51, 85].
These data support our previous finding that S. littoralis antennae house a peripheral circadian clock [ 74].
Chemosensory sensilla, and AgOr-containing neurons in particular, are distributed over the entire length of the female antenna, whereas male antennae house ~3-fold fewer chemosensilla that are restricted to distal segments 12 and 13 [ 4, 50- 52].
Moreover, when a liquid antenna is housed in an elastic material it can be tuned in a novel way.
Interestingly, the second segment of the antenna, which houses Johnston's organ, the fly auditory apparatus [16], showed an intense signal from auditory neurons [17] beneath the cuticular sheath (Fig. 4A').
Esrey's way: "fixed wireless," which circumvents the locals by mounting tiny antennas on houses to receive high-speed Internet service and crystal-clear telephone calls.
The trichoid sensilla on male ECB and ACB antennae typically house three different olfactory neurons that can be differentiated by the amplitude of their electrophysiological response spikes.
Here, we report (1) that polygyne workers express one or two forms of GP-9s, which are demonstrated to be general hemolymph proteins unlikely involved in olfaction, and (2) on the identification of a chemosensory protein specifically expressed in olfactory tissues located on the terminal segments (club) of the antennae that house olfactory sensilla.
Here is a list of some of the other churches housing antennas.
