Psoroptes ovis in camelids

A low prevalence of llama and alpaca holdings in Norway is infected with Psoroptes ovis. The prevalence of infected individuals on each infected holding is also low.

The objective of the surveillance and control programme for Psoroptes ovis is to identify P. ovis positive llama and alpaca holdings with the intension to prevent the spread of Psoroptes mange to the sheep population.
