Abstract

Objective: This study aimed to evaluate studies on the toxicity of pyriproxyfen in animal models of zebrafish and murine and its relationship with microcephaly. Methods: The keywords pyriproxyfen and toxicity were used for the search on Pubmed, Scorpus, ScieLo and ScienceDirect platforms. Articles that used the keywords in the title or abstract were selected. Inclusion criteria were: articles in English or Portuguese that described an experimental study in vivo or in vitro with zebrafish (Danio rerio) and mice. The information extracted were the year of publication, country, animal model and toxicity outcomes. Results: 13 articles were selected. Exposure to application concentration above the recommendation is toxic. No evidence of microcephaly was observed. We observed an increase in the number of publications after the epidemic, the country with the highest number of publications was Brazil and the zebrafish was the most used model. Final considerations: Based on the studies, pyriproxyfen is not related as a cause of microcephaly, however, it causes toxic effects. Given the wide use of this larvicide in arbovirus control programs, we recommend its use with caution.
