Abstract

The sheep itch mite, Psorergates ovis, was recorded in Western Australia for the first time in 1948. This parasite was first detected in New South Wales in 1940 and since that time it has been reported from all of the other States. There is reason to believe, however, that the mite has existed in Australia for many years and that its recognition has been delayed owing to the similarity of the symptoms produced to those resulting from infestation with body lice (Damalinia ovis). The presence of itch mite had been suspected for some considerable time in this State, but a definite diagnosis could not be made until the parasites were recovered from affected sheep and positively identified.
