“Johannesburg is home to one of the world’s largest urban forests, but it’s come under threat from a tiny beetle.
About 200 species of trees – many of them indigenous to South Africa – are afflicted with the pest and the fungus it carries. As scientists desperately look for a solution, many of the city’s trees are dying and experts are concerned the infestation could move from the forest to croplands next.”
“The polyphagous shot hole borer is difficult to control if experts don’t know where it is. Tree Survey has developed a mobile app that allows PSHB infestations to be reported. With ‘two pics and a click’, gardeners and nature lovers can help combat a serious threat facing the trees of South Africa.”
“One of the world’s largest urban forests is under threat from the polyphagous shot hole borer beetle which is thought to have made its way from Southeast Asia on packing crates or through the movement of plant materials. Many of the city’s estimated 6 to 10 million tress are dying and no one has found a way to combat the pest.”
“These Boxelder have been dead for over a year and they have been a breeding ground for shot hole borer.. Recent chemical tests indicate that one heavily infested tree contains over 100,000 beetles – these dead trees need to be removed and disposed of responsibly..!!”
“ROSEBANK – The shothole borer beetle is a threat to the city’s tree’s and residents recently attended a talk on the problem.”
“When spring arrives, I believe that the beetles will become active again. With a possible treatment available we must identify timeously so we can try and get to the borer before it inflicts too much damage to the trees.”
