“…Firstly, the larvae of this bug lacks ocellar lenses. Secondly, the growth of the cornea and the associated retina during the early adult life starts from a thin lens with a narrow band of thickened cuticle, that expands dorso-ventrally to become an almost spherical thick ocellar lens (Insausti 1997).…”

“…The ocelli are well developed with prominent spherical lenses overlying the photoreceptor layer ( Fig. 1A) (Insausti 1997). Descending firstorder interneurones project to contralateral posterior slope, deutocerebrum and suboesophageal, pro-, meso-and metathoracic centres (Insausti & Lazzari 1996).…”

“…These oval cells are filled by granules of brown-reddish pigment, giving place to an "iris", that limits an ovoid "pupil", whose major axis runs horizontally (Insausti 1997). The extent of this pupil was observed to differ among individuals.…”

Although kissing bugs (Triatominae: Reduviidae) are perhaps best known as vectors of Chagas disease, they are important experimental models in studies of insect sensory physiology, pioneered by the seminal studies of Wigglesworth and Gillet more than eighty years ago. Since then, many investigations have revealed that the thermal, hygric, visual and olfactory senses play critical roles in the orientation of these blood-sucking insects towards hosts. Here we review the current knowledge about the role of these sensory systems, focussing on relevant stimuli, sensory structures, receptor physiology and the molecular players involved in the complex and cryptic behavioural repertoire of these nocturnal insects. Odours are particularly relevant, as they are involved in host search and are used for sexual, aggregation and alarm communication. Tastants are critical for a proper recognition of hosts, food and conspecifics. Heat and relative humidity mediate orientation towards hosts and are also important for the selection of resting places. Vision, which mediates negative phototaxis and flight dispersion, is also critical for modulating shelter use and mediating escape responses. The molecular bases underlying the detection of sensory stimuli started to be uncovered by means of functional genetics due to both the recent publication of the genome sequence of Rhodnius prolixus and the availability of modern genome editing techniques.
