Rebollar Téllez Biología human odors skin bacteria vectorial capacity mosquito attraction Mosquitoes and other blood feeding insects are temporal ectoparasites, which move away from the host after a bloodmeal. It is known that blood com ponents are mainly utilized by mosquitoes for egg production and, in a few examples, as anenergy supply. Odors emanating from the host have different substrates from which they originate (e.g. urine, faces, skin, breath).These odors are important as long-range and short-range cues for host recognition. However, the exact relationship betweenhuman body odors and the attractiveness to blood-sucking insects remains unknown. Furthermore, the basis as to why certainindividuals are preferentially bitten by hungry mosquitoes more than others is unclear. The present review briefly summarizesthe sources of human odor that might play a role in mosquito attraction. Evidence suggests that body odors are actually a byproductof the decomposition of odorless skin chemicals, and that the final attraction is due to the balance between attractive andnon-attractive fractions. Finally, the implications of variable human attractiveness in areas of parasite transmission are discussedin relation with the vectorial capacity model. It is suggested that differences in attractiveness should be considered when assessingrisk factors in those endemic transmission foci. 2005 artículo científico 0430-8603 https://www.redalyc.org/articulo.oa?id=42444213 en http://www.redalyc.org/revista.oa?id=424 Folia Entomológica Mexicana application/pdf Sociedad Mexicana de Entomología, A.C.
