Management and Control:

Cyromazine targets larvae inside the leaves
Other insecticides provide control

Two parasitic wasps provide biological control in Europe.
Dacnusa sibirica is used as a biocontrol agent when temperatures are low and infestations are light. Diglyphus isaea is used when temperatures are above 200C. These wasps are often used in combination with cyromazine.
