Apart from visual and thermal cues, chemostimuli guide a variety ofvital behaviours in haematophagous arthropods.
Control strategies aim atdisrupting such chemically mediated behaviours.
In the case of ticks andtriatomine bugs, each of a series of life stages require a blood meal. Despite being equipped with very few olfactory receptors for any givenhost volatile, ticks show attraction to such products at very low doses. Once on the host, the ticks respond to contact chemostimuli and to materecognition stimuli via gustatory receptors.
