==Pathogenesis==
−
*Production losses
−
**Annoyance
−
**Bites can lead to secondary infection by [[Myiasis Producing Flies|myiasis producing flies]] and other muscid species
−
−
*Disease transmission
−
**Pathogenic bacteria and viruses via mechanical transmission
−
**Helminths can be introduced into the host
−
***E.g. ''Stephanofiliaria'' a filarial nemadode found in the skin of cattle overseas
−
−
==Control==
−
*Resident fly so easier to control than visiting flies as spends more time in contact with the host
−
−
*However, [[Ectoparasiticides|insecticide]] resistance can occur quicker
