The first confirmed sighting of the invasive Polyphagous Shot Hole Borer beetle (PSHB) – found in the City of Cape Town - has been announced.

The sighting has been postively identified  by academic experts - Prof. Francois Roets (Department of Conservation Ecology and Entomology, Stellenbosch University) and Prof. Z. Wilhelm de Beer (Forestry & Agricultural Biotechnology Institute – FABI - University of Pretoria).

The PSBH infestation was discovered in the suburb of Somerset West by Mr Phumudzo Ramabulana (City of Cape Town Invasive Species Unit) and Mr Paul Barker (Arderne Gardens) on the 8 March, 2019.

Mr. Elmar van Rooyen, a MSc student from Stellenbosch University - currently working on the PSHB beetle for his thesis - collected samples from infested Liquid Amber and London Plane trees in Somerset West for laboratory analyses.

The identity of the beetle and its symbiotic fungus was confirmed using morphological and DNA sequence analyses, as well as comparisons with the extensive FABI database.
