Importance and distribution

Thyrinula sp. is of quarantine significance due to its pathogenic nature and is found on the Import risk analysis: Vehicle and Machinery list of New Zealand (Biosecurity New Zealand 2007). Thyrinula sp. is also considered as a potential pathogen of concern associated with eucalypts in Australia (USDA 2003). Thyrinula comprises five species found on Eucalyptus species. Thyrinula is host-specific and recorded from Australia (New South Wales), South Africa (Mpumalanga) and South America (Uruguay).
