ABSTRACT: The sensilla who act as thermohygroreceptor, chemoreceptor, or mechanoreceptor are the main sensory structures of insects. Insects carry different types, numbers and      distributions of sensilla in body parts such as head, antenna, mouth parts, and leg segments. In this study, the sensilla types on the head, antenna and mouth parts of Aelia rostrata Boh. (Hemiptera, Pentatomidae) were invastigated with using scanning electron   microscope. According to the results of the study, 4 major types of sensilla with different  diameters and cone-shaped protrusions have been identified: sensilla basiconica, sensilla trichodea, sensilla peg, and sensilla campaniformia. These sensilla show different distributions in the examined structures of the insect. The results obtained from the study were also compared with other species in the literature, and similarities and differences were revealed.
