Tabanus rubidus (Diptera: Tabanidae) is a significant species of the Tabanidae family, known for its veterinary and medical relevance, and is found across Thailand. This study examines the species distribution, genetic diversity, demographic history, and vector-pathogen transmission of T. rubidus collected from all six different regions in Thailand. Molecular techniques, utilizing the cox1 gene, were used to assess genetic diversity, genetic structure, and demographic history. The 16S ribosomal...

Climate change poses a significant threat to global biodiversity, altering species ranges and ecological dynamics. This study investigates the impact of climate change on Tabanus taeniola (Diptera: Tabanidae), a widely distributed horsefly with ecological importance in Africa and South America. Our objective was to model its current habitat suitability and predict future distribution shifts under various climatic scenarios. Using occurrence data from GBIF and and bioclimatic variables from...

Tabanid flies are gaining high medical and veterinary importance due to their role as a vector of many pathogens. In the present study, a total of 3760 female tabanid flies were collected from Narathiwat and Phayao provinces of Thailand. All were identified using the morphological method, DNA barcoding and wing geometric morphometric (WGM) analysis. Eight species were identified, and among them, Tabanus tenens is a new recorded Thai horse fly. Morphologically, 2178 and 1559 females from...

AbstractHorse flies (Diptera: Tabanidae) are significant pests that affect both livestock and humans via their blood-feeding behavior and role as biological and mechanical vectors of several pathogens. The Tokachi district in Hokkaido is a major livestock farming region in Japan, but long-term data on horse fly activity have been lacking for over 40 years. To address this, we conducted a 3-year entomological survey (2022–2024) at 11 livestock farms using one commercial stationary horse fly trap (H-trap) per each farm. Horse flies were collected from early June to late October each year and identified morphologically. A total of 56,542 individuals from 18 species and five genera were collected using H-traps. Tabanus nipponicus (67.91%) and Haematopota tristis (29.99%) were the dominant species. Seasonal abundance showed a unimodal peak in late July to early August, with most activity from early July to late August. Compared to data from the 1980s, the appearance of dominant species has shifted approximately one month earlier, likely due to warming temperatures, as supported by degree-day analysis. Furthermore, a shift in dominance from Hae. tristis to T. nipponicus may reflect land use changes in the region. This study provides updated insights into the species composition and seasonal dynamics of horse flies in a key agricultural area of Japan and highlights the importance of long-term monitoring to assess the impacts of climate and environmental change on pest populations.
