Myxomatosis: the release and spread of the European rabbit flea Spilopsyllus cuniculi (Dale) in the Central District of Victoria.

The European rabbit flea was first released in Victoria in August 1969 at Werribee. Releases were made on five different land forms. At one site the first flea was recovered 2 weeks after release. Fleas were recovered between 4 and 6 weeks after release at the other sites. Differences in establishment and spread on the different land forms were due to physically restricted movement of some rabbit populations. By June 1971 80% of rabbits were infested but an occasional young uninfested rabbit was still found in August 1978. Infestation numbers were higher than in the Mallee region especially on pregnant does.
