Topic:Arthropods
Arthropods encompass a diverse group of invertebrates, including insects, arachnids, and crustaceans, that interact with horses in various ways. These interactions can affect equine health, behavior, and management. Arthropods such as flies, ticks, and mites are common ectoparasites that can cause irritation, allergic reactions, and transmit diseases to horses. Additionally, certain arthropods play roles in the decomposition of organic matter in equine environments, influencing pasture health and manure management. This page compiles peer-reviewed research studies and scholarly articles that explore the interactions between arthropods and horses, focusing on their ecological roles, impact on equine health, and strategies for effective management and control.
Contrasting seasonal patterns in diet and dung-associated invertebrates of feral cattle and horses in a rewilding area. Trophic rewilding is increasingly applied in restoration efforts, with the aim of reintroducing the ecological functions provided by large-bodied mammals and thereby promote self-regulating, biodiverse ecosystems. However, empirical evidence for the effects of megafauna introductions on the abundance and richness of other organisms such as plants and invertebrates, and the mechanisms involved still need strengthening. In this study, we use environmental DNA (eDNA) metabarcoding of dung from co-existing feral cattle and horses to assess the seasonal variation in plant diet and dung-associated a...
Parasites of Horses, Donkeys and Mules in Turkey. Significant numbers of parasites such as protozoa, helminths and arthropods infest equids. Various investigations have been conducted in Turkey to detect these parasites. In this review, all parasites reported in horses, donkeys and mules have been listed. A total of 62, 52 and 21 helminths were recorded in horses, donkeys and mules, respectively. As protozoan parasites, 13 species were detected both in horses and donkeys, and 3 in mules. With regard to arthropods, 40, 23 and 6 species were detected in horses, donkeys and mules, respectively. In the recent years, various molecular diagnostic m...
Summer seasonal prevalence of Culicoides species from pre-alpine areas in Switzerland. Biting midges (Diptera: Ceratopogonidae) are arthropods of veterinary importance since they can transmit pathogens and cause severe allergic dermatitis in horses. Very little is known about the species at higher altitudes and their seasonal dynamics. In this work, adult Culicoides were collected with Onderstepoort UV-light suction traps (OVI) from June to September 2016 at two areas situated at around 1600 m asl (pre-alpine area I, 2 farms) and 2030 m asl (pre-alpine area II, 1 farm) in the Canton of Grisons (south-east Switzerland). Overall, 17 049 Culicoides were collected, including 8...
Patch-scale effects of equine disturbance on arthropod assemblages and vegetation structure in subalpine wetlands. Assessments of vertebrate disturbance to plant and animal assemblages often contrast grazed versus ungrazed meadows or other larger areas of usage, and this approach can be powerful. Random sampling of such habitats carries the potential, however, for smaller, more intensely affected patches to be missed and for other responses that are only revealed at smaller scales to also escape detection. We instead sampled arthropod assemblages and vegetation structure at the patch scale (400-900 m(2) patches) within subalpine wet meadows of Yosemite National Park (USA), with the goal of determining if t...
Biotechnological advances in the diagnosis of little-known parasitoses of pets. Dogs, cats, and horses are popular pets in many countries of the World and they have lived in close proximity with human beings for thousands of years. The effect of pet ownership on human health is well known and there is significant merit in preserving the health and welfare of these animals. Some infections caused by parasitic nematodes and arthropods of dogs, cats, and horses are now spreading in several areas of the world. This is the case of canine spirocercosis, feline aelurostrongylosis, and equine gastro-intestinal and nasal nematode and botfly infections. These diseases affect animal...
[Characterization of Rickettsia spp. circulating in a silent peri-urban focus for Brazilian spotted fever in Caratinga, Minas Gerais, Brazil]. The present study was intended to characterize Rickettsia spp. circulating in arthropod vectors in Caratinga, Minas Gerais, Brazil, by PCR and to investigate the presence of antibodies against the spotted fever Rickettsiae group (SFRG) in dogs and horses. 2,610 arthropods were collected and taxonomically identified. DNA samples obtained from these vectors were submitted to PCR and cycle-sequenced. Ctenocephalides and Amblyomma cajennense showed sequences presenting 100.0% homology with R. felis. A sequence obtained from Rhipicephalus sanguineus showed 99.0% homology with R. felis, and a sequen...
Veterinary use of ivermectin. Following the development of a unique claim structure encompassing both nematode and arthropod species, ivermectin was first introduced as a veterinary parasiticide in 1981. For cattle(c), sheep(s), horses(h) and pigs(p) injectable(c,s,p), oral(c,s,h) and topical(c) products are available delivering ivermectin at 200 to 500 micrograms/kg. Efficacy extends to nematodes of the gastrointestinal and respiratory tracts, conjunctival sac and soft tissues. Among the arthropod parasites claims have been established for the biting fly Haematobia irritans(c), the screw-worm Chrysomyia bezziana(c), larva...
