This Biosecurity Advice notifies stakeholders of the release of the draft risk analysis report for the proposed release of the gall-inducing thrips, Acaciothrips ebneri for the biological control of the weed, prickly acacia (Vachellia nilotica subsp. indica).
This draft report proposes that the biological control agent should be permitted to be released, subject to standard import and release conditions associated with exotic biological control agents.
The draft report is being issued for a 30 calendar day public consultation period, closing on 29 April 2022.
Stakeholders are invited to have their say on the draft report. The department will consider all stakeholder comments received during the consultation period in preparing a final report.
The draft report proposes that the biological control agent, Acaciothrips ebneri, should be permitted to be released to control the weed, prickly acacia (Vachellia nilotica subsp. indica). The risk is estimated to be Negligible, which achieves Australia’s appropriate level of protection (ALOP).
The applicant, the Queensland Department of Agriculture and Fisheries (QDAF), provided a submission in support of their application to release the biological control agent. The submission detailed the results of host-specificity testing, together with other relevant information. This submission is included as an attachment to the draft report.
The standard consultation period for biological control risk analyses is 30 days, which differs from the standard period of 60 calendar days for other risk analyses. This is because the department has consulted extensively with all state and territory governments and the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and there was no opposition to the release of Acaciothrips ebneri as a biological control agent. This approach is consistent with the Revised guidelines for the introduction of exotic biological control agents for the control of weeds and plant pests.
The draft report and information about the risk analysis process are available online.
The department invites stakeholders interested in receiving information and updates on biosecurity risk analyses to subscribe via the department’s online subscription service.
