Article Synopsis
- Lice are specific parasites that feed on birds and mammals by consuming blood or body tissues, which poses economic and health risks for livestock like buffalo.
- This study documents the first instance of the louse Haematopinus tuberculatus found on buffalo in Autazes, Amazonas, Brazil, with 12 specimens collected during milking activities.
- Most lice were found on young calves, indicating a potential for disease outbreaks in the region, although no DNA evidence was found to confirm their presence.

This study aimed to assess the diversity patterns of sand fly fauna across different strata and detect Leishmania DNA in these insects in the Mapinguari National Park in Rondônia and Amazonas states, Northern Brazil. Sand flies were collected with "HP" light traps in the canopy (15 m) and at ground level (1 m) on two trails, during August and November 2021 and March and August 2022. Polymerase chain reaction and DNA sequencing were used to identify Leishmania species.
