“…Of them, 20,970 (20%) were males and 81,723 (80%) were females, with 79.75% being parous and 0.25% blood engorged females [ 34 ]. The specimens were assigned to one of 40 different species ( Table 3 ) without any new species being cited for the Iberian Peninsula with respect to the latest taxonomic catalog published by Alarcón-Elbal and Lucientes [ 47 ].…”

Culicoides Species Communities Associated with Wild Ruminant Ecosystems in Spain: Tracking the Way to Determine Potential Bridge Vectors for Arboviruses

et al. 2015

The genus Culicoides Latreille 1809 is a well-known vector for protozoa, filarial worms and, above all, numerous viruses. The Bluetongue virus (BTV) and the recently emerged Schmallenberg virus (SBV) are responsible for important infectious, non-contagious, insect-borne viral diseases found in domestic ruminants and transmitted by Culicoides spp. Both of these diseases have been detected in wild ruminants, but their role as reservoirs during the vector-free season still remains relatively unknown. In fact, we tend to ignore the possibility of wild ruminants acting as a source of disease (BTV, SBV) and permitting its reintroduction to domestic ruminants during the following vector season. In this context, a knowledge of the composition of the Culicoides species communities that inhabit areas where there are wild ruminants is of major importance as the presence of a vector species is a prerequisite for disease transmission. In this study, samplings were conducted in areas inhabited by different wild ruminant species; samples were taken in both 2009 and 2010, on a monthly basis, during the peak season for midge activity (in summer and autumn). A total of 102,693 specimens of 40 different species of the genus Culicoides were trapped; these included major BTV and SBV vector species. The most abundant vector species were C. imicola and species of the Obsoletus group, which represented 15% and 11% of total numbers of specimens, respectively. At the local scale, the presence of major BTV and SBV vector species in areas with wild ruminants coincided with that of the nearest sentinel farms included in the Spanish Bluetongue Entomological Surveillance Programme, although their relative abundance varied. The data suggest that such species do not exhibit strong host specificity towards either domestic or wild ruminants and that they could consequently play a prominent role as bridge vectors for different pathogens between both types of ruminants. This finding would support the hypothesis that wild ruminants could act as reservoirs for such pathogens, and subsequently be involved in the reintroduction of disease to livestock on neighbouring farms.

“…Biting midges Culicoides are a diverse and widespread genus with more than 1400 species in the world [18], with at least 81 of them present in Spain [19]. Biting midges transmit pathogens with sanitary importance, including the Bluetongue virus and the emergent Schmallenberg virus [18,20], in addition to the majority of avian Haemoproteus (subgenus Parahaemoproteus ) parasites.…”

On the study of the transmission networks of blood parasites from SW Spain: diversity of avian haemosporidians in the biting midge Culicoides circumscriptus and wild birds

BackgroundBlood-sucking flying insects play a key role in the transmission of pathogens of vector-borne diseases. However, at least for the case of avian malaria parasites, the vast majority of studies focus on the interaction between parasites and vertebrate hosts, but there is a lack of information regarding the interaction between the parasites and the insect vectors. Here, we identified the presence of malaria and malaria-like parasite lineages harbored by the potential vector Culicoides circumscriptus (Kieffer). Also, we identified some nodes of the transmission network connecting parasite lineages, potential insect vectors and avian hosts by comparing Haemoproteus and Plasmodium lineages isolated from insects with those infecting wild birds in this and previous studies.MethodsUsing a molecular approach, we analysed the presence of blood parasites in a total of 97 biting midges trapped in the Doñana National Park (SW Spain) and surrounding areas. Also, 123 blood samples from 11 bird species were analyzed for the presence of blood parasite infections. Blood parasites Haemoproteus and Plasmodium were identified by amplification of a 478 bp fragment of the mitochondrial cytochrome b gen.ResultsThirteen biting midges harboured blood parasites including six Haemoproteus and two Plasmodium lineages, supporting the potential role of these insects on parasite transmission. Moreover, ten (8.1%) birds carried blood parasites. Seven Plasmodium and one Haemoproteus lineages were isolated from birds. Overall, six new Haemoproteus lineages were described in this study. Also, we identified the transmission networks of some blood parasites. Two Haemoproteus lineages, hCIRCUM03 and GAGLA03, were identical to those isolated from Corvus monedula in southern Spain and Garrulus glandarius in Bulgaria, respectively. Furthermore, the new Haemoproteus lineage hCIRCUM05 showed a 99% similarity with a lineage found infecting captive penguins in Japan.ConclusionsThe comparison of the parasite lineages isolated in this study with those previously found infecting birds allowed us to identify some potential nodes in the transmission network of avian blood parasite lineages. These results highlight the complexity of the transmission networks of blood parasites in the wild that may involve a high diversity of susceptible birds and insect vectors.

“…The arrival of bluetongue virus (BTV) outbreaks in the new century contributed to an increased number of studies, and some incorporated the use of molecular techniques for the identification of certain closely related species (Ventura et al, 2005). To date, there are 81 species of Culicoides reported in Spain, divided in 9 subgenera, a miscellaneous group and a nomen dubium (Alarcón-Elbal & Lucientes, 2012). Thanks to this new finding the number of species rises to 82 and 28 in Spain and the Autonomous Community of Extremadura respectively (Sánchez Murillo et al, 2013).…”

The ceratopogonid Culicoides paradoxalis Ramilo & Delécolle, 2013 is recorded for the first time in Spain based on reliable morphological evidence according to the previous descriptions of other authors. A total of 438 females (349 nulliparous and 89 parous) and a single male were collected with CDC miniature light traps at three different livestock-associated locations in Extremadura Autonomous Community (Spain) in 2014. Most specimens were captured between June and August, suggesting a univoltine pattern for this species extended over summer and early autumn. Although the number of collections of C. paradoxalis is low in comparison with the dominant species, the occurrence of this species in monitoring surveillance programs should deserve specific attention in order to estimate the accurate ratio of potential vectors unmistakably. Interesting information about the period of flight and illustrated morphological features are presented for C. paradoxalis in the current paper.
