“…This shows compellingly that Culicoides biting midges have survived and coped with environmental challenges in the past and will probably continue to do so in the future. Worldwide, at least 40 Culicoides species are associated with diseases notifiable to the World Organisation for Animal Health (OIE), such as bluetongue (BT) and African horse sickness, but also with epizootic haemorrhagic disease virus, equine encephalitis virus, Akabane virus, bovine ephemeral fever virus (9) and the recently discovered Schmallenberg virus (10). Besides viruses, other pathogens transmitted by Culicoides midges include bacteria, nematoda and protozoa (9).…”

SummaryVector-borne animal diseases pose a continuous and substantial threat to livestock economies around the globe. Increasing international travel, the globalisation of trade, and climate change are likely to play a progressively more important role in the introduction, establishment and spread of arthropod-borne pathogens worldwide. A review of the literature reveals that many climatic variables, functioning singly or in combination, exert varying effects on the distribution and range of Culicoides vector midges and mosquitoes. For example, higher temperatures may be associated with increased insect abundancethereby amplifying the risk of disease transmission -but there are no indications yet of dramatic shifts occurring in the geographic range of Culicoides midges. However, the same cannot be said for mosquitoes: over the last few decades, multiple Asian species have established themselves in Europe, spread and are unlikely to ever be eradicated. Research on how insects respond to changes in climate is still in its infancy. The authors argue that we need to grasp how other annectant changes, such as extremes in precipitation (drought and flooding), may affect the dispersal capability of mosquitoes. Models are useful for assessing the interplay between mosquito vectors expanding their range and the native flora and fauna; however, ecological studies employing classical mark-release-recapture techniques remain essential for addressing fundamental questions about the survival and dispersal of mosquito species, with the resulting parameters fed directly into new-generation disease transmission models. Studies on the eventual impact of mosquitoes on animal and human health should be tackled through large-scale integrated research programmes. Such an approach calls for more collaborative efforts, along the lines of the One Health Initiative.

“…About 1400 species of this genus have been recorded throughout the world (Borkent, 2014). Only females of some Culicoides species, however, act as vectors of pathogens (viruses, protozoa and filarial nematodes) of medical and veterinary importance (Mellor et al, 2000;Elbers et al, 2013). These biting midges have recently been associated with outbreaks of important viral epizoonoses in northern Europe (BT and SB).…”

“…Behavioural studies using olfactometers or wind or flight tunnels in which a specific number of biting insects are released are very rare (Bhasin et al, 2000b) due to the difficulty of obtaining a sufficient number of insects, given the complexity of maintaining many Culicoides species of interest under controlled conditions. Only a few speciesof limited interest in northern Europe -are commonly bred (Jones, 1964;Fahrner and Barthelmess, 1988;Kremer and Lienhart, 1998), and these do not include species of the subgenus Avaritia (particularly Culicoides obsoletus Meigen 1818), considered to be vectors of BTV and SBV (Mehlhorn et al, 2007;Carpenter et al, 2008;Hoffmann et al, 2009;De Regge et al, 2012;Elbers et al, 2013).…”

a b s t r a c tSome Culicoides biting midge species (Diptera: Ceratopogonidae) are biological virus vectors worldwide and have recently been associated with outbreaks of important epizootic diseases such as bluetongue and Schmallenberg in northern Europe. These diseases, which affect domestic and wild ruminants, have caused considerable economic losses. Knowledge of host preferences of these biting midges -especially of the relevant vectors of arboviruses near farms, such as Culicoides obsoletus in northern Europe -is essential to understand pathogen transmission cycles and the epidemiology of associated diseases. This study aimed to determine host preferences of C. obsoletus using an in-field flight tunnel containing pairs of calf, sheep, chicken, and human hosts (and controls) and a laboratory two-choice bioassay containing volatile extracts of host skin (and controls). Behavioural responses of nulliparous C. obsoletus females in the in-field flight tunnel showed a preference for human (but also calf and sheep) hosts, probably due to their exhalation of greater quantities of carbon dioxide. The laboratory experiment revealed that volatile organic compounds released from the skin of chicken and sheep seemed to attract this species. Culicoides obsoletus, thus, seems to have a wide host range and to be particularly attracted by humans under field conditions. A better understanding of vector-host interaction could enable the development of control strategies against adult biting midges, by exploiting insect-repelling or -attractive semiochemicals. Volatile extracts of chicken and/or sheep skin could be used to identify volatile compounds attractive to C. obsoletus, which in turn could be used in baited traps.

It has been demonstrated that BTV and SVB share Culicoides vectors in Europe (Elbers et al 2013;Koenraadt et al 2014).As a result of a study conducted on the epidemiology of the bluetongue virus in the Caribbean and Central America, a total of 42 species of Culicoides were determined. From these arthropods, 18 species were in the country, C. insignis being the most common species.…”

Absence of IgG antibodies against Schmallenberg virus in ruminant sera (bovine, goat and sheep) Abstract Schmallenberg virus affects ruminants, which causes significant economic losses. The virus is transmitted through vectors of the genus Culicoides; however, other studies do not rule out the possibility of sexual transmission due to its presence in semen. For this reason, the National Service of Animal Health of Costa Rica (SENASA) imposed restrictions on the import of semen from animals from the European Union in 2013. Consequently, SENASA conducted a study to determine the presence or absence of antibodies against this virus in bovine, ovine and caprine samples. As a result, no antibodies against this virus were detected in the 748 samples tested. It was concluded that Schmallenberg virus was not circulating in Costa Rican ruminants during the tested period.Keywords: Ruminants, SENASA, Schmallenberg virus, Costa Rica, serology. ResumenEl virus de Schmallenberg afecta a rumiantes produciendo pérdidas económicas importantes, el cual se transmite a través de artrópodos del género Culicoides, sin embargo, no se descarta la posibilidad de transmisión sexual debido a la presencia del virus en semen, razón por la cual, el Servicio Nacional de Salud Animal de Costa Rica (SENASA), estableció restricciones a la importación de semen de rumiantes procedentes de la Unión Europea en el 2013. En consecuencia, el SENASA realizó un estudio para determinar la presencia o ausencia de anticuerpos contra este virus en muestras de bovinos, ovinos y caprinos. Como resultado de este estudio no se encontró la presencia anticuerpos contra el virus de Schmallenberg en ninguna de las 748 muestras evaluadas, por lo que se concluye que este virus no está circulando en los rumiantes de Costa Rica.Palabras claves: Rumiantes, SENASA, virus Schmallenberg, Costa Rica, serología.Rev. Ciencias Veterinarias, Vol. 35, N° 2,[103][104][105][106][107][108][109][110][111][112] IntroductionReports of emerging and re-remerging viral diseases have increased over the last decade. Some of these etiological agents produce diseases that concern health authorities and professionals worldwide because of the unpredictable effects and impact of these agents (Ruiz-Fons 2012).Diseases transmitted by arthropods that affect human and animal populations are causing serious local and international health problems, especially in underdeveloped countries. Schmallenberg virus (SBV) is a clear example of these emerging diseases (Alarcón-Elbal & Lucientes 2012). This epizootic disease began in the summer of 2011 in northwestern Germany and the eastern region of the Netherlands. In October 2011, the virus was identified by researchers of the Friedrich Loeffler Institut (FLI), Federal Research Institute for Animal Health in Germany (Bilk et al. 2012). Schmallenberg disease was characterized by clinical signs such as fever, diarrhea, and decreased milk production (Gariglinany et al. 2012). The acute disease in pregnant females was followed by an epidemic of stillbirths an...
