A successful attempt at artificial mating by applying the method of decapitation
in O. aureoargentatus is recorded. The hitherto unknown first stage larva
of this oestrid fly is described and compared with that of O. avis. It proved
to be non-pathogenic to sheep. Further unsuccessful trials with the tethering method
of Weintraub (1961) are also described.
