Simulation Studies of African Horse Sickness and Culicoides imicola (Diptera: Ceratopogonidae)

Journal of Medical Entomology, 1996
A simulation model of African horse sickness in Spain was developed to investigate what factors affect the likelihood of an epidemic after the introduction of the virus. The model included 2 host species (horses and donkeys) and 1 vector species (Culicoides imicola Kieffer).

Morpho-functional identification of abdominal olfactory receptors in the midge Culicoides imicola

Journal of Comparative Physiology A, 2010
The aim of the present study was to examine the presence and the possible role of abdominal olfactory sensilla in Culicoides imicola mediating the search for potential hosts and oviposition sites, by means of a morphological, electrophysiological and behavioural approach. The results reported here show that in the midge C.

An alternative method of blood-feeding Culicoides imicola and other haematophagous Culicoides species for vector competence studies

Veterinary Parasitology, 2005
The use of cotton wool pads saturated with blood/virus mixture for oral infection attempts was compared to membrane feeding for the assessment of vector competence in C. imicola Kieffer and C. bolitinos Meiswinkel (Diptera, Ceratopogonidae). Although lower infection rates were obtained using pad feeding, it was possible to clearly distinguish the ...

Entry of bluetongue vector Culicoides imicola into livestock premises in Spain

Medical and Veterinary Entomology, 2009
Abstract. Culicoides imicola Kieffer is considered to be the main vector of bluetongue disease (BT) and African horse sickness (AHS) in the Mediterranean basin. It has been assumed that this midge species is exophilic and, consequently, that stabling of livestock should provide effective ...

Newly emerged nulliparous Culicoides imicola Kieffer (Diptera: Ceratopogonidae) with pigmented abdomen

Veterinary Parasitology, 2009
The method of segregating nulliparous and parous females of Culicoides spp. based on the presence of burgundy-red pigment inside the abdominal wall of parous Culicoides midges, is used worldwide. Out of 320 females of Culicoides imicola trapped by emergence traps, set over an artificial breeding site for 10 and 24 days, 73 (22.8%) showed a red ...

Spatial distribution of Culicoides imicola , the main vector of bluetongue virus, in Spain

Veterinary Record, 2006
BLUETONGUE (BT) is a disease caused by a virus of the genus Orbivirus that is mainly transmitted among vertebrate hosts by several species of biting midges of the genus Culicoides (Diptera: Ceratopogonidae) (Du Toit 1944, Mellor and Pitzolis 1979). BT virus (BTV) can replicate in all species of ruminants and causes severe disease in certain breeds of ...

Comparison of black and white light for collecting Culicoides imicola and other livestock-associated Culicoides species in South Africa

Veterinary Parasitology, 2006
Comparison of the effectiveness of 8W fluorescent black and white light sources, in two 4x4 Latin squares (16 replicates) designs under South African conditions, showed black light to be up to three time more effective in collecting Culicoides imicola Kieffer (Diptera, Ceratopogonidae) and other South African Culicoides species. Four Culicoides species,
