First report of immature forms of Anopheles albitarsis s.l. (Diptera: Culicidae) collected in artificial containers in an urban area of the state of Acre, Western Brazilian Amazon.

Abstract

Background: This study reports the first documented occurrence of immature forms of Anopheles albitarsis in artificial breeding sites within an urban area of Acre, Brazil.

Methods: Second-instar larvae were collected from a water tank.

Results: The collected larvae were identified as Anopheles albitarsis, representing the first report of this species in artificial breeding sites in an urban area of Acre.

Conclusions: The detection of immature forms in artificial containers suggests potential adaptation of the vector to urban settings and highlights concerns regarding the increased risk of malaria transmission in areas previously regarded as low-risk.
