General Comments

The Risk Register entry for this pest is extremely incomplete and it cannot be compared with other pests on the Risk Register at the current time. As this is a Regulated Non Quarantine Pest (RNQP) listed in the legislation, we are making available the information we have gathered on the pest so far. It is possible that we will add new information to this pest entry in due course, but as there are a great many RNQPs this may take some time.
