“…In comparison to UV light, incandescent light traps captured both fewer species of biting midges and lower numbers of C. obsoletus females. A similar difference has also been demonstrated through comparative studies conducted in South Africa (Venter and Hermanides 2006), Spain (del Río et al 2013, González et al 2016) and in the US (Anderson and Linhares 1989, Wieser‐Schimpf et al 1990). Despite UV light being the most widely used tool for biting midge surveillance, the ecological mechanism through which light of different wavelengths attracts Culicoides to traps remains poorly understood (Carpenter et al 2008).…”

Effective surveillance is essential for protecting livestock from Culicoides biting midges and the viruses they transmit. The objective of this study was to determine how the baiting system used in traps (UV, incandescent light, incandescent light with CO2, and incandescent light with CO2 and 1‐octen‐3‐ol) influences estimates of midge population abundance, parity, and diel activity. This was achieved through a standardized trapping protocol conducted in three habitats in Sweden. UV light traps caught the most Culicoides species and more C. obsoletus complex females than incandescent light traps. Traps baited with CO2 plus 1‐octen‐3‐ol caught more female C. impunctatus than incandescent light traps. No consistent effect of bait type was found on C. obsoletus parity rate, as estimated from the proportion of midges with presence or absence of pigmentation. Midge activity, as reflected by trap catches, peaked between ‐3 h and +3 h relative to sunset, with UV traps catching significantly more female C. obsoletus complex and C. impunctatus at and after sunset than before sunset. We conclude that baiting system can influence biting midge collections, even using identical traps. Effective surveillance may require more than one bait type and kairomones to attract species that do not feed exclusively on cattle.

“…Culicoides obsoletus (Meigen) and Culicoides scoticus Downes and Kettle, by contrast, responded randomly to every colour of LED used with the exception of red, which was less attractive to all species (Hope et al ., ). Overall, LED traps collected fewer Culicoides than the Centers for Disease Control (CDC) UV light suction trap (Hope et al ., ; González et al ., ) or other commercially available domestic light sources (Wakefield et al ., ). Harrup et al .…”

“…Studies evaluating the use of various colours of light have been conducted in Australian (Bishop et al ., , ), South American (Silva et al ., ), Indian (Harrup et al ., ) and European (Hope et al ., ; González et al ., ) Culicoides species. Although these studies demonstrated attraction specifically to UV, blue and green light, they also suggested that particular Culicoides species may react differently to various light colours.…”

Culicoides biting midges (Diptera: Ceratopogonidae) are vectors of a range of orbiviruses that cause important veterinary diseases such as bluetongue and African horse sickness. The effective monitoring of Culicoides species diversity and abundance, both at livestock and near potential wildlife hosts, is essential for risk management. The Onderstepoort 220-V ultraviolet (UV) light trap is extensively used for this purpose. Reducing its power requirements by fitting low-energy light-emitting diodes (LEDs) can lead to greater flexibility in monitoring. A comparison of the efficiency of the 220-V Onderstepoort trap (8-W fluorescent UV light) with the efficiency of the 220-V or 12-V Onderstepoort traps fitted with red, white, blue or green LEDs or a 12-V fluorescent Onderstepoort trap demonstrated the 220-V Onderstepoort trap to be the most efficient. All the results showed nulliparous Culicoides imicola Kieffer females to be the dominant grouping. Despite the lower numbers collected, 12-V traps can be used in field situations to determine the most abundant species.

“…Additionally, CDC traps were set throughout the study area during 2016 and 2017. We used traps with UV light as they are recommended to attract Culicoides [ 54 ]. Moreover, since this study is part of a broader one aimed at studying the community of dipteran vectors, we also used incandescent light traps.…”

Culicoides paolae and C. circumscriptus as potential vectors of avian haemosporidians in an arid ecosystem

et al. 2018

BackgroundHaemosporidians are the most important vector-borne parasites due to their cosmopolitan distribution and their wide range of hosts, including humans. Identification of their vectors is critical to highlight ecologically and epidemiologically relevant features such as host specificity or transmission routes. Biting midges of the genus Culicoides are considered the main vectors of Haemoproteus spp., yet important information on aspects such as vector feeding preferences or vector-host specificity involving haemosporidian parasites is frequently missing.MethodsWe assessed the abundance of Culicoides circumscriptus and C. paolae and blood sources of the latter at the nests of cavity-nesting bird species (mainly the European roller Coracias garrulus) and in their surroundings. We also explored the prevalence and genetic diversity of avian haemosporidians in parous females of both species.ResultsBoth C. circumscriptus and C. paolae were abundant in the study area and common at European roller nests. Culicoides paolae had a diverse ornithophilic diet, feeding on at least seven bird species. Human DNA was also detected in the blood meal of some individuals. Four Haemoproteus lineages, including a new one reported here for the first time, were isolated from parous females of both biting midges.ConclusionsCulicoides circumscriptus and C. paolae can play a locally important role in the transmission dynamics of Haemoproteus parasites in a community of cavity-nesting bird species in an arid ecosystem.
