BACKGROUND: Understanding ecological relationships among species and their pathogens is essential for assessing disease dynamics and associated risks to human, animal, and environmental health. Some haematophagous ceratopogonid species feed on birds and may act as vectors for haemoparasites, viruses, and bacteria. However, no reports have documented these insects feeding within the internal organs of birds.
OBJECTIVES: This study aims to describe the first recorded occurrence of ceratopogonids feeding within the respiratory system of debilitated kelp gulls and cormorants.
METHODS: As part of the Beach Monitoring Project of the Santos Basin (PMP-BS Area SC/PR - IBAMA - ABIO No. 640/2015), we rescued debilitated coastal birds from the municipalities of São Francisco do Sul and Itapoá, in northern Santa Catarina State, Brazil, and examined the biting midges infesting them.
FINDINGS: Approximately 18.2% (31/172) of the kelp gulls and 15.8% (3/19) of the cormorants analysed were infested internally with Leptoconops (Megaconops) floridensis Wirth and, in sporadic cases, with two species of Culicoides. Kelp gulls accounted for 91.2% of the infested birds (31/34), and the trachea, air sacs, and lungs were the most frequently affected regions of the respiratory system (~83.9%).
MAIN CONCLUSIONS: This is the first recorded occurrence of ceratopogonids feeding within the innermost part of the avian respiratory system.
