Update on biological control treatment of Mealybugs

An update and photos from Drew, one of our amazing Horticultural Apprentices, on the biological treatment being carried out on the Ficus trees in The Forum Street:

“So yesterday at work I got to apply biological controls to our very poorly Ficus trees. They are suffering from a serious bout of Mealybug which suck the sap and are vectors for diseases. To help combat this in an eco-friendly way, we have applied a healthy dose of Australian ladybirds (Cryptolaemus montrouzieri) which will spend the next few weeks munching on the Mealybugs and hopefully leaving the Ficus much happier”.

Ghostly going ons?

Ghostly going ons in The Forum? Don’t worry our Ficus trees haven’t turned into huge ghosts!

The trees have a Mealybug infestation, so we are introducing predatory insects (Cryptolaemus montrouzieri) to deal with them.

Cryptolaemus are harmless to people, pets and wildlife and will not become a pest in their own right.

By using predatory insects as an organic form of biological control, we are avoiding the use of harmful pesticides.

The fleece coverings have been placed over the trees to keep the process and insects contained.

These information sheets have been produced by our Horticultural Apprentices and will be on display next to the Ficus trees to explain the process to passerbys.
