“…In the pre- sent study, many specimens of C. plaumanni were captured using both the CDC traps and live bait, and they are most likely the main agents responsible for the emergence of the disease. The occurrence of this insect has been reported in Brazil (in the state of Amazonas), Argentina, Peru (Felippe--Bauer et al 2008), Bolivia, and Colombia (Spinelli et al 2009). However, there are no case reports of allergic dermatitis in domestic animals associated with this species, although a few insects have previously been collected close to sheep and poultry in Peru (Felippe-Bauer -unpublished data).…”

Allergic dermatitis caused by Culicoides in Texel sheep in the state of Pará, Brazil

Clinical and epidemiological data were obtained during monthly visits to the farm. Skin biopsies were performed for histopathological examinations, and insects were captured with Centers for Disease Control and Prevention (CDC) traps and live-bait entomological vacuum devices. The property housed a herd of both genders, with 45 Santa Inês sheep of different ages and 72 Texel adults. Of the 72 Texel sheep, 56 were affected. Of these, 24 exhibited alopecia, erythema, edema, and crust in the ears, on top of the head, and less often, around the eyes. In addition to the lesions described above, 14 animals exhibited hyperpigmentation of the ears and/or around the eyes and crust in the nose. Another 18 animals exhibited chronic lesions characterized by deformed and thickened ears, alopecia with hyperpigmentation, and in most cases, secondary bacterial infections with abscesses and/or myiasis. Some of these animals had lost part of their ears. Histologically, the lesions were characterized as orthokeratotic hyperkeratosis, acanthosis, vacuolization, and necrosis of epidermal cells. An inflammatory infiltrate was present in the dermis, which was composed mainly of eosinophils and macrophages, some lymphocytes and mast cells, and few neutrophils, in addition to edema and collagen deposition. The Santa Inês sheep were not affected. Among the captured insects, 294 specimens of Culicoides (Hoffmania) plaumanni Spinelli, 57 specimens of C. (Hoffmania) insignis Lutz, and 27 specimens of other Culicoides species were identified. We conclude that C. plaumanni, C. insignis, and possibly other Culicoides species are involved in the etiology of allergic dermatitis in Texel sheep in the state of Pará. Santa Inês sheep in the same region and under the same conditions were not affected, which suggests lower susceptibility of these animals.

“…In addition, their intensive biting is a significant nuisance and can cause dermatological problems when the insects are very abundant (Blanton & Wirth 1979, Borkent 2005. According to Borkent (2009), about 1,300 species of this genus have been described worldwide, of which 114 have been recorded in Colombia (Spinelli et al 2009). Some of these species have been reported to cause problems in the Colombian Andes due to their high biting rates; Culicoides puracensis Wirth & Lee was reported as a pest in the uplands (páramo) of Puracé by Wirth and Lee (1967) and Culicoides pachymerus has been reported as a public health problem in western Boyacá since 1987 (Villareal 1998).…”

The breeding sites of Culicoides pachymerus are described for the first time in western Boyacá Province, Colombia, where Bloodsucking midges of the genus Culicoides Latreille belong to the family Ceratopogonidae. These insects have a long evolutionary history, with fossil records dating back 90 million years; at this time, they were already feeding on vertebrate blood (Borkent 2005). Culicoides midges have public health importance as vectors of viruses, nematodes and protozoans. In addition, their intensive biting is a significant nuisance and can cause dermatological problems when the insects are very abundant (Blanton & Wirth 1979, Borkent 2005. According to Borkent (2009), about 1,300 species of this genus have been described worldwide, of which 114 have been recorded in Colombia (Spinelli et al. 2009). Some of these species have been reported to cause problems in the Colombian Andes due to their high biting rates; Culicoides puracensis Wirth & Lee was reported as a pest in the uplands (páramo) of Puracé by Wirth and Lee (1967) and Culicoides pachymerus has been reported as a public health problem in western Boyacá since 1987 (Villareal 1998). Santamaría et al. (2008) reported peridomiciliary biting rates of up to 51.8 females/person/5 min for the latter region.As in other members of the family Ceratopogonidae, the life cycle of Culicoides midges consists of an egg stage, four larval instar stages, a pupal stage and an adult stage. The ecology and population dynamics of the larvae are key to understanding their patterns of abundance and the relationship of these patterns to environmental factors such as climate and habitat. Furthermore, control of the immature stages may play a significant part in pest and vector control. However, little is known about the microhabitats in which Culicoides larvae develop and immature stages have been described for only 238 (Borkent 2005) of the currently known species (Borkent 2009). Although the breeding sites of Culicoides are extremely variable, all are aquatic or semi-aquatic, including damp or wet decomposing vegetation, wet leaf packs, manure, many different types of phytotelmata, tree holes, swamps, ponds, lakes, streams and river margins, mangrove swamps, bogs and salt marshes (Borkent 2005).Despite the relatively wide neotropical distribution of C. pachymerus, which is found in Brazil, Colombia, Ecuador, Venezuela, Guatemala, El Salvador and Panamá (Forattini 1957, Wirth et al. 1988, the preferred breeding sites of this species have not been determined. The aim of the present study was to identify the microhabitats in which immatures of C. pachymerus occur.Sampling was carried out in three scattered rural dwelling areas (veredas) in the foothills of the eastern Cordillera of the Andes, which surrounds the central Magdalena River valley in Boyacá department: vereda Chizo Cuepar in the municipality of San Pablo de Borbur, vereda Santa Rosa in the municipality of Tunungua and vereda Topo Grande in the municipality of Pauna (Fig. 1).These rural dwelling areas were sele...
