Abstract. Ecology and distribution of Culicoides Latreille 1809 species (Diptera: Ceratopogonidae) in Belgium in the surrounding of a beefs rearing farm. Bluetongue is a non-contagious disease that affects domestic and wild ruminants. Since its spreading to Northern Europe in 2006, this viral epizooty caused considerable economical losses on the ovine and bovine livestock. The biological vectors of the bluetongue virus (BTV) are biting midges belonging to the genus Culicoides. Many elements still remain unknown about their biology, physiology, ecology and distribution. This study shows that these biting midges are much more abundant on farm level than in the nearby meadows; these last ones nevertheless present a much more specifi c diversity. So possibility of migration between the meadow and the farm is voiced for the C. chiopterus and C. dewulfi species. Females are much more represented than males for the farm and the meadow alike. The physiology observation of these ones is realized throughout the study.Résumé. La Maladie de la Langue bleue est une maladie non contagieuse qui affecte les ruminants domestiques et sauvages. Depuis son extension au Nord de l'Europe en 2006, cette épizootie virale a engendré des pertes économiques considérables sur le cheptel ovin et bovin. Les vecteurs biologiques du virus de la FCO (BTV) sont des moucherons appartenant au genre Culicoides. De nombreuses inconnues subsistent encore sur leur biologie, physiologie, écologie et distribution. Cette étude montre que ces moucherons piqueurs sont bien plus abondants au niveau de la ferme que dans les prairies avoisinantes; ces dernières présentent toutefois une plus grande diversité spécifi que. C'est ainsi que la possibilité de migration entre la prairie et la ferme est émise pour les espèces C. chiopterus et C. dewulfi . Tant pour la ferme que pour la prairie, les femelles sont beaucoup plus représentées que les mâles. L'observation de la physiologie de celles-ci est réalisée tout au long de l'étude.

“…Insects collected were stored in 70% ethanol prior to Culicoides midge segregation according to species morphology (unpublished wing pattern keys, PVVD, ARC-Onderstepoort Veterinary Institute), sex and parity status (Dyce, 1969) as nulliparous (unpigmented), parous (pigmented), blood fed and gravid females. Large light trap midge collections were sub-sampled (Van Ark and Meiswinkel, 1992).…”

The efficacy of alphacypermethrin-treated high density polyethylene (HDPE) mesh applied to jet stalls against Culicoides biting midges (Diptera: Ceratopogonidae) was determined by mechanical aspiration of midges from horses and using Onderstepoort 220V downdraught black light traps in four blocks of a 3 x 2 randomised design under South African field conditions. The alphacypermethrintreated HDPE mesh applied to the stall significantly (P = 0.008) reduced the number of Culicoides midges, predominantly Culicoides (Avaritia) imicola Kieffer, mechanically aspirated from horses housed in the stall. The mesh reduced the Culicoides midge attack rate in the treated stall compared to the untreated stall and a sentinel horse by 6 times and 14 times, respectively. The number of Culicoides midges and C. imicola collected in light traps from the untreated and alphacypermethrin HDPE mesh-treated stalls did not differ significantly (P = 0.82). Alphacypermethrin-treated HDPE mesh could be used to reduce exposure of horses in jet stalls to Culicoides midges, specifically C. imicola, and the risk of midge-borne Orbivirus transmission.

“…Large collections were sub-sampled (Van Ark and Meiswinkel, 1992). Based on abdominal pigmentation (Dyce, 1969), females of all species were age-graded into nulliparous (unpigmented), parous (pigmented), gravid or freshly blood-fed.…”

Despite some limitations suction light traps are the primary tool used for the collection of Culicoides species (Diptera: Ceratopogonidae). The range of attraction of the Onderstepoort light trap is not known but an insight into the range of a trap will determine where the trap must be positioned relative to the hosts present, possible breeding sites and environmental structures in the trapping vicinity. It will therefore contribute to a more meaningful interpretation and comparison of results between trapping events. In the present study the number of Culicoides midges collected in a single trap was compared to those of traps made with an additional trap respectively 1 m, 4 m and 8.5 m away from the first. Treatments between sites were rotated in three replicates of a 4x4 Latin square design. While interactions were found in traps 4 m apart no statistically significant interactions were found when they were 8.5 m apart. The range of attraction, indicated by the interaction between two traps, will be between 2 m and 4 m. In interpreting light trap results the limitations of this collection method needs to be taken into consideration.2
