The progressive invasion of Bactrocera dorsalis (Diptera: Tephritidae) in South Africa

Invasion Note


The discovery of the exotic fruit fly pest Bactrocera dorsalis (Diptera: Tephritidae), previously recognized as Bactrocera invadens, on the African continent in 2003 raised biosecurity concerns in South Africa where agriculture is of major socio-economic importance. This prompted the development of a nationally coordinated system to prevent introduction of this pest into the country. A steering committee was constituted to provide a platform for multi-stakeholder cooperation. A national action plan on B. dorsalis was developed. A surveillance network was initiated to provide for early detection of B. dorsalis. The first B. dorsalis eradication campaign was launched in 2010 following the detection of the pest in the northern border region of South Africa. Multiple point incursions were detected thereafter in the northern parts of the country and for the first 2 years all of these were considered successfully eradicated. However, the rate and geographic spread of incursions increased over time. In March 2013 the pest was declared present in the Vhembe district, Limpopo Province. All areas affected by B. dorsalis were placed under quarantine and eradication actions are still ongoing in areas other than the Vhembe district. The national control strategy on B. dorsalis continues to be focussed on preventing further incursions, slowing the spread of the pest and monitoring the extent of its distribution within South Africa.
