The Polyphagous Shot Hole Borer (PSHB) beetle
Is a beetle that has been introduced into South Africa and it is spreading at an alarming rate within our urban forests!
Millions of trees are expected to die.
Currently known areas of infestation are - Johannesburg, Midrand, Durban, Pietermaritzburg, George, Mpumalanga, Knysna, Kruger National Park and Hartswater.
It is important to note that the borer beetle itself does not kill the tree. Rather the fungus (Fusarium euwallaceae) that she carries with her. The beetle burrows into the tree, while doing so she deposits the fusarium in the tunnels.
The infested tree’s vascular system begins to fail, leaves start thin on the ends of branches, they turn brown, the branch and eventually the tree will die.
London Plane, English Oak, Boxelder, Chinese Maple, Japanese Maple and many more are attacked.
What to look out for?!
