[more ▼] The ovine catarrhal fever (FCO) caused considerable economic losses on the Belgian sheep and cattle livestock during the year 2007. The biological vectors of the bluetongue virus (BTV) are diptera belonging to the genus Culicoides. Their survival, their activity and their distribution depend on many variables still relatively unknown. The setting up of an effective control strategy against these biting midges requires a better knowledge of their biology and their ecology, as well as adult status as larval one. This control strategy against Culicoides biting midges can be combined with some hygienic measures in farming, reinforcing the vaccination programme of Belgian cattle against FCO serotype 8.

[more ▼] Bluetongue, coming from South Africa, is now present on the five continents : from the tropics to the toundra, from the sea level to an altitude of 4000 m. In fact, we have observed these last years a big increase of this illness to the North; it has first touched South Europe to reach Belgium in 2006. Its repartition coincides with the Diptera area distribution of genus Culicoides. Some of these species of biting midges play the role of biological vector of the bluetongue virus, which touches domestic and savage ruminants. The main aim of this study is to underline the larval resting places of the different Culicoides species. Therefore, an extraction technique of the larvas with a MgSO4 solution (direct flottation) as an incubation method in greenhouse has been applied for the different collected substratum samples concerning both sites of Grand-Manil. The enumeration of the immature stages collected by this first technique and the identification of the biting midges appearing during this second technique allow to associate the different species to the varied biotopes. In parallel a bright trapping has been executed as well in the site of the farm as well in the site of the meadow in Grand-Manil. This one allows in fact to follow the dynamics of biting midges Culicoides populations through according to the weather conditions. Moreover, a comparison can be realized between the results from the incubation and these from the UV trapping. [less ▲] Detailed reference viewed: 96 (9 ULg) |
