Couverture géographique
The 19 collection sites were chosen by the Mauritius Veterinary Services and the Ministry of Health based on their field expertise. The selection criteria were to cover all the different districts of Mauritius, to represent the different farming practices and hosts present on the island, and finally, to include farms whose owners agreed to the presence of the trap. Two sites (Casela, Riviere des Anguilles) were recreational animal parks with a mixture of domestic and African animals, while the other were livestock farms.

Couverture taxonomique
A total of 38,186 Culicoides individuals were collected. Culicoides imicola and C. enderleini were present and distributed throughout the island, with 17 positive sites out of 19 prospected sites and 18 positives sites out of 19, respectively. Culicoides bolitinos and C. kibatiensis were recorded at 8 and 2 sites, respectively, with sites positive for C. bolitinos located in the south-east of the island and those for C. kibatiensis in the centre of the island.

Méthodes d'échantillonnage
The survey targeted farms housing cattle, sheep, goat or mixed. The traps were positioned outside stables or near animal resting areas and operated from at least one hour before dusk to one hour after dawn, with the exact geographical coordinates of each farm recorded by the operator. The traps used were black light suction traps (Onderstepoort Veterinary Institute design). Insects attracted to the light were collected using a fan that directed them into a beaker containing soapy water. The soap ensured the insects sank and prevented them from drying out. Once collected, the specimens were transferred into 70% ethanol at room temperature for preservation and transported to the lab. Damaged or incomplete specimens were excluded. In cases of excessively large samples, subsampling was performed to streamline the identification process, following a modified protocol outlined in Van Ark and Meiswinkel (1992). Specifically, if the total insect volume exceeded 3 mL, a subsample was taken, offering significant time savings. After subsampling, a preliminary sorting step was conducted under a stereomicroscope to isolate Culicoides from other insect species based on morphological traits, including body shape, antennal segment count, and wing patterns. Non-Culicoides specimens were not identified. Morphological identification was conducted following the morphological atlas from Desvars et al. (2015).
| Etendue de l'étude | Sampling was operated from 10th to 20th April 2023 (end of the warm season, known to be the most favourable period of abundance for insects, including Culicoides), with one night collection at each site. |

| Introduction | In Mauritius, an active surveillance system is currently in place at points of entry for diseases of public health importance (Iyaloo et al. 2024), however Culicoides-Borne Diseases (CBD) are not included. Measures currently in place to ensure that the country remains free from diseases of veterinary importance include (i) importing livestock only if it is officially certified as ‘disease-free’ and (ii) a quarantine period depending on the species, after entry into Mauritian territory. Therefore, the risk of potential introduction of CBDs to Mauritius is likely due to the country’s significant trade links with endemic countries, the large number of bovines, equines and small ruminants imported each year and the high number of tourists visiting the island. Although diseases vectored by Culicoides are not clinically observed in Mauritius, serological surveys have proven the circulation of EHDV and BTV with at least 4 serotypes circulating in Rusa deer (Jori et al. 2007) and in cattle, sheep, goat and deer (Cêtre-Sossah et al. 2025). According to published literature, only two studies have investigated the presence of Culicoides in Mauritius. The first one was conducted in 1990 where respectively 27 individuals of Culicoides imicola Kieffer, 35 individuals of Culicoides brevitarsis Kieffer and 2 individuals of both species were collected from traps operated over 1 night in Mon Loisir, Palmar and Medine (Boorman et al. 1992). The identification of C. brevitarsis was tentative, as Culicoides bolitinos Meiswinkel and C. brevitarsis are morphologically closely related species. In the second study conducted in 2007, a total of 1,597 individuals of C. imicola and 11,678 individuals of C. enderleini were collected from traps operated for 1 night in 3 Rusa deer farms (Jori et al. 2007). So far, no entomological surveys have been conducted in livestock farms at the island scale. Culicoides diversity in Reunion Island, 220 km south-west of Mauritius, has recently been investigated (Desvars et al. 2015, Grimaud et al. 2019). Five Afrotropical species were recorded: C. imicola, C. bolitinos, Culicoides enderleini Cornet and Brunhes, Culicoides grahamii Austen and Culicoides kibatiensis Goetghebuer. An altitudinal gradient was observed, with C. imicola being the dominant species at low altitudes and C. kibatiensis at high altitudes. Abundance showed high spatial heterogeneity. In Mayotte, an island of the Comoros archipelago located in the Mozambique Channel, C. enderleini and Culicoides rhizophorensis Khamala and Kettle were detected in a study conducted by Cornet and Brunhes (1994), while in a more recent study, Garros et al recorded at least 17 described Afrotropical species and one undescribed species (Garros et al. 2019). The low abundance and rare occurrence of C. imicola, generally considered the most abundant species in livestock in the Afrotropical region, was unexpected. The most abundant and frequent species was Culicoides trifasciellus Goetghebuer, which is not currently considered a vector species, but whose potential role in the transmission of infectious agents needs to be studied in more detail. In Madagascar, C. imicola and species of the Schultzei group have been collected, however, the Culicoides species diversity is likely to be underestimated considering the size of this island and its unique ecological diversity (Cornet et al 1994, Augot et al. 2017, De Meillon et al. 1961). Two species have been recorded in the Seychelles - Culicoides kusaiensis Tokunaga present in Micronesia and Culicoides leucostictus Kieffer considered an Afrotropical species (Lambrecht et al. 1970, Wirth et al . 1977). Considering the current health situation in the context of CBDs affecting the livestock sector and human populations worldwide (Gondart et al. 2024, Gourjault et al. 2025, Naveca et al. 2024, Scachetti et al. 2025), it is important to update and revise the Culicoides faunistic inventory in Mauritius to assess the risk of disease transmission and provide guidelines for the development of preventive and control strategies aimed at minimizing the risk of outbreaks for both animal and public health. In this study, surveys were carried out on 19 farms with different host diversity from 10 to 19 April 2023, to investigate the abundance, diversity and spatial distribution of Culicoides biting midge species in Mauritius, with the aim of assessing the risks of CBDs transmission and gaining a better understanding of the epidemiology of Culicoides borne viruses on the island. |
