schmallenberg virus in culicoides latreille (diptera: ceratopogonidae) populations in france during 2011-2012 outbreak. | following the emergence of the schmallenberg virus (sbv) in 2011 in germany and its rapid spread in europe, culicoides (diptera: ceratopogonidae) collected through the french surveillance network were analysed in order to record the presence of virus genome into species diversity collected, to assess the minimum infectious rates (mir) and the virus circulation dynamics in culicoides populations. two vector activity periods were selected (2011, august to october, 53 sites and 2012, june to octobe ... | 2017 | 28815930 |
phenology and attraction of potential culicoides vectors of bluetongue virus in basque country (northern spain). | bluetongue virus is transmitted by culicoides biting midges (diptera: ceratopogonidae). culicoides associated with livestock were captured using cdc blacklight traps at three btv-infected farms in basque country between november 2007 and december 2008. twenty-seven and nineteen culicoides species were collected in outdoor and indoor habitats respectively. indoor insect community represented 86.1% of the whole captured individual biting midges. culicoides obsoletus/culicoides scoticus (two siblin ... | 2011 | 22137350 |
the culicoides 'snapshot': a novel approach used to assess vector densities widely and rapidly during the 2006 outbreak of bluetongue (bt) in the netherlands. | a novel method was developed and implemented during the recent outbreak of bluetongue (bt) in sheep and cattle in the netherlands to obtain rapidly a 'snapshot' of culicoides vector densities at the national level. the country was divided into 110 raster cells, each measuring 20 km x 20 km; within 106 of these cells, a farm was selected with a minimum of 10 cattle and sampled for culicoides for one night only using the onderstepoort-type blacklight trap. prior to deployment of the light traps in ... | 2008 | 18657871 |
first report of 13 species of culicoides (diptera: ceratopogonidae) in mainland portugal and azores by morphological and molecular characterization. | the genus culicoides (diptera: ceratopogonidae) contains important vectors of animal and human diseases, including bluetongue, african horse sickness and filariosis. a major outbreak of bluetongue occurred in mainland portugal in 2004, forty eight years after the last recorded case. a national entomological surveillance plan was initiated in mainland portugal, azores and the madeira archipelagos in 2005 in order to better understand the disease and facilitate policy decisions. during the survey, ... | 2012 | 22536340 |
culicoides species communities associated with wild ruminant ecosystems in spain: tracking the way to determine potential bridge vectors for arboviruses. | 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 unknow ... | 2015 | 26510136 |
contribution to the knowledge of culicoides (diptera: ceratopogonidae) host preferences in france. | knowledge on host-feeding pattern of blood-sucking insects helps to understand the epidemiology of a vector-born disease. we determined blood meal origin from blood-fed culicoides thanks to molecular techniques. a set of primers was used to selectively amplify segment of vertebrates' prepronociceptin gene from abdomen of engorged culicoides (diptera: ceratopogonidae). vertebrate dna was successfully amplified in 91% of blood-fed culicoides assayed. direct sequencing and comparison of resultant s ... | 2010 | 20967462 |
flight and swarming behaviour of culicoides species (diptera: ceratopogonidae) on a livestock farm in northern spain. | the efficacy of sweep nets and a cdc white light-suction trap for the sampling of culicoides species (diptera: ceratopogonidae) were compared on a livestock farm in northern spain during the summer of 2013. a total of 6,082 specimens representing 26 species were collected with sweep nets in 4 areas at di erent heights (ground level, 1.5 m, and 3 m), and 8,463 specimens representing 28 species with a single white light trap. eight species - culicoides brunnicans, culicoides punctatus, culicoides ... | 2017 | 28675253 |
description of culicoides paradoxalis sp. nov. from france and portugal (diptera: ceratopogonidae). | a new species, culicoides paradoxalis ramilo and delécolle (diptera: ceratopogonidae), is described from specimens collected in france (corsica and southeast region) and portugal. this species resembles culicoides lupicaris downes and kettle, and can be distinguished from this species and from culicoides newsteadi austen by its wing pattern, in addition to the absence of spines on the tarsomere 4 of female mid leg. in male, the presence of two appendices on the sternite 9 together with the absen ... | 2013 | 25113346 |
a survey of culicoides developmental sites on a farm in northern spain, with a brief review of immature habitats of european species. | culicoides species (diptera: ceratopogonidae) belonging to the obsoletus and pulicaris groups are considered to be the main vectors of bluetongue virus (btv) in non mediterranean europe. selected terrestrial microhabitats (n=17) on a farm in northern spain were sampled repeatedly over a year-long period and characterized for use by culicoides species for immature development. concurrent use of cdc light traps showed the presence of 37 species and 66,575 specimens of adult culicoides. a total of ... | 2013 | 22999100 |
