Uranotaenia spp

Uranotaenia spp are a genus of mosquitoes which feed habitually on dogs worldwide[2].

Species which are pathogenic to dogs include:

  • Uranotaenia unguiculata[3]
  • Uranotaenia browni
  • Uranotaenia nepenthes
  • Uranotaenia pandani[4]
  • Uranotaenia nataliae[5]
  • Uranotaenia sapphirina[6]

Mosquitoes lay their eggs on water or in dry places that tend to flood seasonally. The larvae molt four times within the first two weeks of hatching and then pupate. Within 24 hours after emergence from the pupa, female mosquitoes begin seeking blood, feeding every day or every second day on a host until sufficient protein stores allow them to begin laying eggs. It is the repeated feeding which makes them vectors for so many diseases and a cause of blood loss when feeding in swarms[7].

These mosquitoes are a primary vector of dog heartworm, Dirofilaria immitis[8][9], and a potentially important vector of arboviruses (Barmah Forest, Ross River, everglades virus).

Preventative control of mosquito populations is the most effective method of disease control.

Drugs such as fipronil[10] and permethrin[11] are effective in long-term management strategies.
