Nodules on a cow due to Dermatobia spp flies

Dermatobia are a parasitic bot fly which causes skin disease as well as lechiguana in cattle worldwide[1].

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

As well as causing skin lesions due to salivary proteases[3], the hides are often condemned at slaughter.

Topical insecticides such as pyrethrins (eg, cypermethrin or cyfluthrin) help control these parasites[4].

Potential vaccines are being developed to help minimise disease impact on cattle[5].
