In our studies on Castrophilus species and their control in Turkey, we observcd that some horses treated with Neguvon expelled
larvae of Rhinoestrus purpurcus (nasal bot of horsc) in their feces.
Thus we found the opportunity to study partly the prevalance of this
parasite andits control with Neguvon. This is a preliminary report
on Rhinoestrus purpureus infestation and the promising effect of
Neguvon for its control.
Rhinoestrus purpureus and its larva from horses was found in
Austria and described by Brauer (2) for the first time. The classic
paper on the morphology, biology and pathogenesis was written by
Portschinsky (20). The studies on the horse nasal bot have since
been continued by Russian authors, especially with respect to their
veterinary and medical importance. A good review of the studies
with respect to the morphology, biology, pathogenecity and distribution of Rhinoestrus purpureus was made recently by Zumpt
