Summary

On 23 March 2011 one possible exotic fruit fly specimen was detected in a Methyl Eugenol baited trap in the Tshipise area of the Limpopo Province, the closest international border being that with Zimbabwe. The NPPO of South Africa initiated a delimiting survey on 30 March 2011 in accordance with the South African Bactrocera invadens Action Plan. Subsequently, two further specimens were detected on 26 May 2011 in 2 separate Methyl Eugenol baited traps in the Tshipise area, within 3 km from the first detection site.

The fruit fly specimens were identified as Bactrocera invadens by the nominated local fruit fly expert and reported to Directorate Plant Health, Department of Agriculture, Forestry and Fisheries in accordance with the relevant legislation and National Action Plan. Subsequently this identification has been confirmed by an internationally recognised fruit fly taxonomist.

A risk assessment was conducted and phytosanitary actions were implemented on 7 June 2011 to prevent movement of fruit from the area under delimitation.

Eradication was initiated on 7 June 2011; it includes the application of weekly protein bait sprays and the deployment of male annihilation blocks in the quarantine area. The status of the pest in this area is Absent: Pest eradicated.

Danger

Nature of immediate or potential danger of Bactrocera invadens has been prevented by successful eradication.
