| Description: | Research on Culicoides in Algeria is crucial due to their potential role in transmitting vector-borne diseases and the lack of in-depth knowledge about their biology and ecology. The Mila region, in particular, is a potential hotspot for several vector-borne diseases due to its favorable environmental conditions. This study aims to fill this gap by examining the ecological structure of Culicoides and assessing the impact of environmental and climatic factors on their abundance and diversity. The entomological study was conducted over a three-month period, from February to April 2024, covering six sites: Vieux Mila, Terrai Bainen, Tassadane Haddada, Chelghoum Laid, Tadjenanet, and Derrahi Bousselah. A total of 651 specimens were collected, representing 10 different species. Among these, the Culicoides nubeculosus complex was the most dominant, followed by Culicoides pulicaris and the Culicoides obsoletus complex. Analysis of Culicoides distribution revealed that the Culicoides nubeculosus complex, Culicoides pulicaris, Culicoides imicola, and Culicoides parroti were present at all sampled sites, while Culicoides circumscriptus had a more restricted occurrence. Species richness was particularly high in Vieux Mila and Tassadane Haddada, with 10 species each. The study also examined the impact of climatic factors. A significant positive correlation was observed between the Culicoides nubeculosus complex and temperature, while other species showed positive correlations with temperature and negative correlations with precipitation, except for Culicoides kingi, which correlated positively with precipitation. This study has enhanced our understanding of the diversity and abundance of Culicoides in the Mila region. The results highlight the importance of environmental variables in the distribution of Culicoides and the need for further research to manage the health risks associated with these vectors and improve disease control strategies. |
