Southern Brazilian geographic distribution of Migonemyia migonei (Diptera: Psychodidae), a putative vector of Leishmania infantum (Kinetoplastida: Trypanosomatidae): a systematic review

This systematic review gathered information on the spatial distribution in southern Brazil of the sandfly Migonemyia migonei, a possible vector of Leishmania species that cause visceral leishmaniasis (VL). Articles were searched from the PubMed, Scielo, Web of Science, and Scopus databases using the keywords: Migonemyia migonei AND Parana, Migonemyia migonei AND Santa Catarina, Migonemyia migonei AND Rio Grande do Sul, phlebotomine AND Parana, flebotomineo AND Parana and sandfly AND Parana, phlebotomine AND Santa Catarina;, flebotomineo AND Santa Catarina and sandfly AND Santa Catarina, phlebotomine AND Rio Grande do Sul;, flebotomineo AND Rio Grande do Sul, and sandfly AND Rio Grande do Sul. The initial search identified 322 articles that met the selection criteria. Empty files or duplicated were then excluded. The titles were screened, and the full texts were obtained. This review included 36 articles, covering 72 of the 399 (18.04%) municipalities in Parana state, one of the 295 (0.33%) in Santa Catarina, and two of the 497 (0.40%) in Rio Grande do Sul. Mg. migonei was found in 54 municipalities of Parana state, in one municipality of Santa Catarina, and in one of Rio Grande do Sul. Based on the wide distribution of Mg. migonei in the municipalities of Parana, greater monitoring is required regarding cases of VL in humans and animals in this region, in addition to epidemiological investigations of these cases of suspected autochthony, as well as increased prevention and control efforts. More studies on VL are required in Santa Catarina and Rio Grande do Sul.

Automated summary

This systematic review collected information on the spatial distribution of the sandfly Migonemyia migonei in southern Brazil, which is a possible vector of visceral leishmaniasis. A total of 36 articles were included in the review, covering municipalities in Parana, Santa Catarina, and Rio Grande do Sul. The wide distribution of Mg. migonei in Parana highlights the need for increased monitoring and control efforts in this region, while further studies on visceral leishmaniasis are required in Santa Catarina and Rio Grande do Sul.
