Aedes spp

From Cow
Adult Aedes spp mosquito

Aedes spp are a parasitic mosquito found worldwide.

Species of Aedes which are pathogenic to cattle include:

  • Aedes aegypti[1]
  • Aedes dorsalis
  • Aedes mcintoshi
  • Aedes ochraceus
  • Aedes scapularis[2]
  • Aedes campestris[3]

These mosquitoes are primarily a 'worry' to cattle, causing skin rashes, but may also transmit arboviruses such as Rift Valley fever[4] and Tahyna virus[5]. The mosquito has a predilection for moist environments and is commonly found near rice farms in the USA[6].

Treatment is relatively effective with most insecticides, although resistance to older chemicals is common. The use of avermectin-based drugs has proven effective at population control of this insect in cattle herds.
