Lutzomyia spp

From Cow
Adult Lutzomyia

Lutzomyia spp (f. Psychodidae) are a parasitic sand fly which causes 'worry' and myiasis in cattle worldwide.

Lutzomyia spp live in sandy aquatic environments and feed on cattle, causing intense pruritus as well as vesicular stomatitis.

This sand fly can also transmit leishmaniasis in cattle, other animals and humans[1].

Species of Lutzomyia which have been recognized as disease causing in cattle include:

  • L. whitmani[2]
  • L. ovallesi[3]
  • L. longipalpis[4]

Topical insecticides such as pyrethrins (eg, cypermethrin or cyfluthrin) help control these parasites[5] are effective, but physical removal of larvae is also essential to eliminate secondary infections.
