According to a municipal announcement, the insect was imported from China due to insufficient controls and has been devastating the “silkworm tree” in recent years. Xylotrechus chinensis first appeared in Athens between 2019 and 2020, causing severe damage and resulting in the loss of 5,000 trees so far.

Mulberry trees are a significant type of tree in Athens’ streets and parks, offering multiple environmental benefits. Hence, the need for protective measures is critical. The protection program is a collaborative effort involving the Benakeio Phytopathological Institute, the Agricultural University of Athens, and the Institute of Mediterranean Forest Ecosystems.

The program involves injecting a plant protection formulation into the trunks of the trees. So far, 5,100 trees have received these injections, with a target of 8,000 by the end of August.

In the announcement, the municipality of Athens emphasized that “the action plan, utilizing innovative equipment and scientific methods, aims primarily to protect natural capital and preserve urban greenery.”
