In Aedes albopictus various types of sensillae were on the head and its appendages with distinct morphological features. The antennae and maxillary palps play a major role in host detection, and other sensory-mediated behaviors. Six long sensilla chaetica were arranged in circular shape and spread uniformly across the diameter of the antennal flagellomers. Maxillary palp is a relatively simple organ compared to antennae, consists of five segments, which densely covered dorsal side with flattened scales, but chemosensory sensilla on ventral side. Thus, a desirable model for exploring neuromolecular networks surrounds chemo- and mechanosensation. Proboscis analyses gustatory code via food intake and involved in identification. Labellum exhibits the most of sensory structures on the proboscis. Numerous sensillatrichoidea distribute on antennal flagellomers. A significant difference in diameter of sensillacoeloconica that protruding from distal tip of antennal flagellomers. Sensillachaetica with greater morphological variation were distributed throughout Ae. albopictus head and appendages. Variation between different sensillae indicates their functions. Aporous sensilla play the mechanoreceptive role but, porous sensilla were contact chemoreceptors and olfactory ones. sensory mechanisms were extensive studied, about Asian tiger mosquito, Ae. albopictus sensory systems is insufficient.
