Jedes Jahr gibt es in der Region um den Süßen See in Sachsen-Anhalt zwei vollständig ausgebildete Apfelwicklergenerationen. So ist der Apfelwickler u. a. in einer über 30 Jahre alten Idared-Anlage seit 2007 ein großes Problem.

Trotz intensiver Spritzfolgen konnten keine Bekämpfungserfolge erzielt werden. Deshalb stellte der Betriebsleiter diese Anlage zu Versuchszwecken zur Verfügung.
