sensillum

(sĕn-sĭl′əm)
n. pl. sen·silla (-sĭl′ə)
A simple sense organ of an arthropod or other invertebrate that consists of one cell or a few cells and may take the form of a hair or bristle.

sensillum

(pl. sensilla) any small sense organ or receptor (particularly in insects) used for the detection of touch, taste, smell, heat perception, sound or light perception. While most sensilla respond to stimuli from outside the body - for example, taste organs in the feeding of many butterflies and flies -some sensilla act as proprioreceptors, detecting internal changes such as the flexion of joints.

2016) study was confined to the shape of the third segment and the structure of the AD, but it left unexamined the fourth segment, which contains a multitude of sensilla that play a key role in locating the settlement site (Walker et al.

The researchers observed that bees that had previously been more social but were now more solitary had reduced numbers of sensilla, suggesting that because their behaviors required less sensory energy to be expended, their physical bodies responded by making their antennae less complex.

A pair of cervical ventral sensilla usually present, but if absent then with a patch of anterior katepisternal setae; antennal ascoids usually simple, at most with a proximal protuberance; male flagellomere 1 usually with the external ascoid apically implanted in relation to the internal ascoid; other characteristics variable .

Some of these sensilla (rheo, chemo-, photo- and mechanoreceptors) could possibly be used for host finding [4,32,36,37] particularly touch receptors, since the fluke depends on it in locating and maintaining contact with the host.

Considering this, we are of the opinion that aggregation behavioural response may depend on the density of bedbugs, number of sensilla on the antenna (23, 29-30), olfactory receptors neurons responding (22, 24).
