This black and yellow striped leaf beetle of American origin came to Europe via ships in the 19th century. The beetle is about 10 mm in size and is very harmful.
Also known as:
As a newcomer, the Colorado pota
The beetles hibernate in the soil at a depth of 20 – 50 cm on plots where potatoes have been grown and hatch again from late April to late May. The beetles crawl or fly to young pota
As a hobby gardener, it is therefore important to capture or destroy first-generation beetles to limit egg deposition.
Check the pota
Found eggs and larvae must be destroyed.
Crush the eggs and larvae and leave the remains. Those remains attract the larvae of ladybugs that also eat the eggs of the Colorado pota
