Biosecurity Advice 2015/07 - Draft risk analysis report for the release of Tachardiaephagus somervillei for the biological control of yellow lac scale (Tachardina aurantiaca)

​1 July 2015

This Biosecurity Advice notifies stakeholders that a draft risk analysis report has been issued, to consider a proposal for the release of the microhymenopteran parasitoid Tachardiaephagus somervillei for the biological control of yellow lac scale (Tachardina aurantiaca). The draft report is being issued for 30 days consultation. Written comments and submissions are invited by 31 July 2015.

The Department of Agriculture has issued a draft risk analysis report assessing an application from the Director of National Parks to release the microhymenopteran parasitoid Tachardiaephagus somervillei for the biological control of yellow lac scale (Tachardina aurantiaca) on Christmas Island. In support of this application, the applicant has provided a submission detailing results of host specificity testing, along with other relevant information. This submission is included as an attachment to the draft report.

A preliminary draft of this report was distributed to state and territory departments of primary industry and the Commonwealth Scientific and Industrial Research Organisation (CSIRO) through the Plant Health Committee (PHC). Comments received through this consultation process were incorporated into the draft risk analysis report.

The Director of National Parks submitted an application for the release of Tachardiaephagus somervillei in November 2014.

The Department of the Environment also has an approval process under the Environment Protection and Biodiversity Conservation (EPBC) Act 1999. Under Section 303EE (4) of the EPBC Act, risk analysis reports prepared by the Department of Agriculture may be used by the Environment Minister in making a determination to include the item on the List of specimens suitable for live import (the live import list). The Department of Agriculture has consulted with the Department of the Environment prior to the release of the draft report and Environment agrees with the recommendations in this report.

The draft report proposes that the biological control agent should be released. The draft report has identified moderate off-target effects with negligible potential consequences that would be associated with the release of Tachardiaephagus somervillei. The risk is estimated to be negligible, which meets Australia’s appropriate level of protection (ALOP).

The draft report, attachment and information about the risk analysis process are available on the department’s website

In accordance with the IRA handbook 2011, this risk analysis has been undertaken as a non-regulated analysis of existing policy. Stakeholders will have up to 30 days to submit written comments on the draft report. Comments must be submitted by 31 July 2015. 

Please pass this notice to other interested parties. If those parties wish to be included in future communications on this matter they should contact Plant Biosecurity.
