Orchopeas spp

From Dog
Adult Orchopeas howardi[1]

Orchopeas spp are a common hematophagous parasitic prairie dog flea which has been reported on hunting dogs.

These fleas, primarily a parasite of wild mammals, infect dogs as an accidental host.

Species which are pathogenic to dogs include:

  • Orchopeas howardi[2]
  • Orchopeas leucopus[3]

Clinical signs include pruritus and localized dermatitis associated with flea activity.

A high prevalence of Wolbachia spp endosymbionts have been reported with these fleas[4].

Treatment is usually effective with a range of insecticidal drugs such as fipronil and permethrins.
