“…However, as stated earlier, the disease could have been circulating in this area without detection because of its low morbidity. This might be explained by the topography which changes from flat to mountainous with peaks exceeding 2000 m. Bishop et al (2000) found that, rather than along the trajectories, the vectors were found in greater abundance at the bottom of the Great Dividing Range, a mountain range in New South Wales (Australia). The fact that no outbreaks were found in these mountain areas might be due to lack of suitable habitats for the midges or lack of suitable hosts.…”

“…Until now, ground station data have been the prime source for modelling the spread of Culicoides by wind (Bishop, 2000;Alba et al, 2004). The two main advantages of using ECMWF gridded data are: (i) the possibility to assess trans-boundary spread of diseases without having to collate and com- bine data from various meteorological institutes manually; and (ii) the continual availability, at standardised time intervals, of contemporary and archived data.…”

“…The modern view is that these long-distance movements are not accidental on the part of the insect but instead actively initiated and maintained (reviewed in Reynolds et al, 2006). There are suggestions that the long-distance movements by Culicoides may be terminated not only when the wind drops (Sellers, 1992), but also by the influence of the topography of the terrain (Bishop et al, 2000(Bishop et al, , 2005 and even actively by the insect ceasing to move its wings which results in its landing even in strong winds. For this dispersal process to be of epidemiological importance, the midge must survive long enough after landing to replicate the virus to a transmissible level.…”

“…Bishop et al (2000) estimated the per-season colonization rate of vectors into an area seasonally free of C. brevitarsis midges next to a region with year-round populations. They looked at the rate and locations of the dispersal into the seasonally free area over several summers and related the dispersal to the speed and direction of the prevailing winds, weather conditions, and topography.…”

Quantifying the wind dispersal of Culicoides species in Greece and Bulgaria

Abstract. This paper tests the hypothesis that Culicoides (Diptera: Ceratopogonidae) species can be propagated by wind over long distances. Movement patterns of midges were inferred indirectly from patterns of the spread of bluetongue outbreaks between farms (using outbreak data from 1999-2001 for Greece, Bulgaria and Turkey) and then matched to concurrent wind patterns. The general methodology was to determine wind trajectories to and from each outbreak site based on the horizontal and vertical wind components of the European ReAnalysis-40 (ERA-40) dataset from the European centre for medium-range weather forecast (ECMWF). Forward trajectories (downwind or where the windvectors pointed to) and backward trajectories (upwind or where the wind-vectors originated from) were calculated for each outbreak for the period from one week before to one week after it had been recorded. These wind trajectories were then compared with the general outbreak patterns taking into consideration the different serotypes involved. It was found that the wind trajectories could be matched to the temporal distribution of the outbreak cases. Furthermore, the spread of the infected vector via the calculated wind trajectories was corroborated by molecular evidence. The conclusion is that the methodology presented is appropriate for quantifying the risk of spread of infected Culicoides midges by wind and that this approach could form an important component of a regional early-warning system for bluetongue.

“…This was expected, since late summer and autumn months of the northern hemisphere usually coincide with falling temperatures, combined with increasing wind and precipitation. It is well known that climatic factors play an imperative role on biting midge's flight activity and consequently the number/or species of Culicoides caught (Bishop et al 2000;Blackwell 1997). In this study, the four most common species C. obsoletus s.s., C. punctatus, C. riethi, and C. pulicaris represented~47, 31, 7, and 5 %, respectively.…”

Community analysis of biting midges (Culicoides Latr.) on livestock farms in Denmark

et al. 2014

This study presents descriptive statistics and community analysis of adult biting midges trapped at 16 livestock farms by means of light traps on Zealand and Lolland-Falster, Denmark. A total of 9,047 male and female Culicoides divided into 24 species, were caught. Biotic and abiotic factors ranging from presence of different host species (cattle or sheep/goats), presence of small woody areas or wetlands in the surrounding landscape, and agricultural practice (organic or conventional) were included in the community analysis. Only differences in the Culicoides communities between conventional and organic practices were tested significantly different. Total numbers of Culicoides individuals were higher on the organic farms than on the conventional farms. The larger loads of biting midges on the organic farms may be due to free-ranging animals that attracted the midges on pastures and carried them to the stable environment (the cattle of the conventional farms were held inside the stables). Presence of deciduous trees within 500 m of the farms resulted in higher numbers of Culicoides obsoletus s.s., while presence of wetlands increased the numbers of Culicoides punctatus and Culicoides pulicaris. Furthermore, Culicoides riethi and Culicoides puncticollis (subgenus Monoculicoides) were recorded in high numbers on individual farms. C. puncticollis was found for the first time in Denmark and so far only recorded from Zealand.
