Video: The polyphagous shot hole borer (PSHB) is a tiny, invasive black beetle from Asia that has recently been discovered in South Africa. Although only 2 mm in length, this tiny beetle has detrimental consequences for South African trees, as it carries a destructive fungus, Fusarium euwallaceae, from tree to tree.
Here’s a handy list of the tree species which have been known to be infected by the polyphagous shot hole borer already.
Dr Trudy Paap is a participant in the International Plant Sentinel Network who was tasked to do routine surveys for tree pests and diseases in the National Botanical Gardens of South Africa, a project funded by the South African National Biodiversity Institute. It was during one of these surveys that she noticed small lesions resembling shotgun marks on the stems and branches of mature London plane (Platanus x acerifolia) in the historical avenue of the KwaZulu-Natal National Botanical Garden in Pietermaritzburg.
