Tabanidae (Diptera) captured on horses in Amazon Forest fragments of the state of Rondônia, Brazil.
Abstract: Tabanidae is one of the most diverse families of hematophagous dipterans. Tabanids, in general, are mechanical vectors of some pathogens. Given the vector importance and the lack of knowledge of the tabanid fauna in horses in Amazon Forest fragments of the state of Rondônia, this work aimed to determine the season that the different species of horse flies prefer to carryout hematophagy on horses and verify whether the horse fly community remains the same throughout the year. The sampling areas for tabanid captures were in the municipality of Monte Negro, Western Amazon, Brazil. Four new occurrences were recorded for the state of Rondônia: Stenotabanus albilinearis, Tabanus fuscofasciatus, T. macquarti and T. restrepoensis, which increases the number of species for the state to 109. The horse flies were most frequently collected on the hind leg (43.15%) and front leg (31.11%), followed by the belly (7.41%) and the ear (5.18%). In the other anatomical regions, the collection frequency was 13.15% of the remaining individuals.

This research examines the behavior of Tabanidae flies (a type of horse fly) in the Amazon forest fragments of Rondônia, Brazil, identifying their preferred seasons for blood-sucking behaviour, investigating whether their community makeup changes yearly, and reporting four new species in the area.
Objective of the Research
- The study aimed to increase the understanding of tabanid flies, considered as mechanical vectors of some pathogenic agents, in the state of Rondônia in the Brazilian Amazon.
- Specifically, it sought to identify the season preferred by these flies for blood-sucking behavior on horses, and to determine if the composition of the fly community changes across the year.
Research Setting
- Tabanid fly samples were collected in the municipality of Monte Negro in the Western Amazon region of Brazil.
Key Findings
- The research resulted in the identification of four new occurrences of tabanid fly species in the state of Rondônia: Stenotabanus albilinearis, Tabanus fuscofasciatus, T. macquarti, and T. restrepoensis, increasing the documented species count to 109 in the region.
- Most horse flies were found on the hind leg (43.15%) and front leg (31.11%) of horses. Some were found on the belly (7.41%) and ear (5.18%), and 13.15% on other body parts.
Significance of the Research
- This research contributes to the understanding of the behaviour and distribution of tabanid flies in the Amazon. It could help in controlling these pests and managing the diseases they potentially transmit to horses and other livestock.
