The DAFF hereby provides notice of the detection of Brevipalpus lewisi on grapevine rootstock mother material in the Western and Northern Cape provinces. The first detection was confirmed by morphological examination of slide-mounted specimens that was finalized on 24 February 2015. The identification has been confirmed by an internationally recognized expert. Subsequent surveys followed during 2015 and were repeated in 2016 to determine the presence/absence of B. lewisi in other provinces. The pest status was found as reported above. Surveys in other provinces and on hosts other than grapevine are still on-going.
Movement of propagative material of affected nurseries from Northern and Western Cape provinces to the rest of South Africa are restricted in accordance with the Agricultural Pests Act, 1983 (Act No. 36 of 1983) to prevent further spread of this pest to other provinces.
