Main research question/goal

The boxwood moth is spreading rapidly throughout Flanders. The damage caused by the caterpillars is causing great concern among producers, traders, owners and caretakers of boxwood plants. A correct and efficient approach will keep this pest under control, but knowledge about it is not always available and it is difficult to reach the target group. The aim of this project is to slow down the further spread of boxwood moth using straightforward communication about its monitoring and control. The target group consists of professional users, public authorities and private individuals.

Research approach

In order to determine the exact time of day for monitoring and subsequent control of boxwood moth, two reference populations shall be closely monitored throughout the season in a continuous manner. We perform visual inspections of box plants weekly to detect eggs, larvae, pupae, spinnacles and damage symptoms, from April to October. Pheromone traps are used to observe the activity of the moths. In addition, cage tests are used to test and assess the effectiveness of a number of physical, biological and chemical control methods in practice.


Based on the information obtained from the monitoring and control tests, a feasible and efficient control strategy is drawn up tailored to the user. This will take into account the degree of infestation, the number and size of the plants, the practical feasibility and the financial aspect. The application of sustainable integrated control (IPM) requires the use of non-chemical controls in addition to monitoring.

In concrete terms, each boxwood user is guided through various communication channels to learn to recognize, monitor and control the boxwood moth and its damage. The campaign is based around the website, which reflects the latest knowledge gained from this project.
