Abstract

Introduction: Mosquitoes belonging to the Culicidae family gather arbovirus vectors and cause great annoyance to human populations, due to hematophagous habits of females and transmission of diseases such as dengue, yellow fever, zika, chikungunya and malaria. Objective: To analyze, through a bibliographical survey, the factors involved in blood preference by mosquitoes, in addition to the main studies that discuss this theme. Method: The survey was carried out in the PubMed, Google Academic and SciELO databases, in the Portuguese, English and Spanish languages, selecting articles published between the years 2004 and 2018, which brought together the oldest study, up to the most current one found in the searches on the topic. Results: Of the analyzed studies, 13 articles that presented a relation with the theme were selected. In these studies, it has been shown that in different parts of the world, the main factors responsible for blood preference are odor, genetic factors, ABO system, availability of hosts in the area and the pheromone produced by females that attracts other individuals to the site.Conclusions: The existence of different factors influencing the preference of mosquitoes for human blood is a fact, and despite this, the subject still needs more conclusive analysis. Thus, knowledge of the factors involved may be used mainly in the prevention of mosquito-borne diseases.
