Raising awareness about monitoring and controlling the boxwood moth (Cydalima perspectalis) in Flanders
By now everyone has heard of the boxwood moth. But where does this pest come from? Why is it a problem and can you do something about it? Research shows that control is perfectly possible, provided there is good pest control.
The boxwood moth reached our country in 2010 and in a short period of time has established itself almost all over the country.
Why is the boxwood moth a pest?
The butterfly itself is beautiful, but the caterpillar is voracious and can quickly eat an entire boxwood plant bald. Moreover, the population expands rapidly.
Main research questionIlex crenata (Japanese holly) is used as an alternative to boxwood which has lost popularity because of the boxwood moth. I. crenata is used as a hedge plant or in various pruning shapes. Differences in soil requirements between Buxus and Ilex crenata can cause problems in the garden.
The Bokrijk Arboretum houses an exceptional collection of varieties of Japanese holly, a species often used as a substitute for boxwood. IILVO, KU Leuven and Plant Select intend to use this collection for breeding purposes to develop new cultivars.
