The box tree moth is a dangerous enemy of the box tree. The caterpillars of the box tree moth begin their feeding inside the tree and are therefore often only noticed when immense damage has already occurred. Young caterpillars usually eat only the uppermost leaf layer, while adult caterpillars eat both the leaves and the bark of the shoots, leaving only the leaf veins. This causes the areas above to die.
The females of the box tree moth deposit their eggs well hidden inside the box tree plants. After a period of only a few days the larvae hatch and start feeding on leaves and twigs of the box tree. The larvae grow up to a length of 5 cm passing through several larval stages. During this time the damage suffered by the box tree can lead to its premature demise. After a feasting period of 1 to 3 months, the larvae pupate to be succeeded within one week by the full-grown adult box tree moth which restarts the described circle above. Between 3 and 4 generations of box tree moth can develop over the course of one season. The generation gap is 4 to 6 weeks and depends on the prevailing climatic conditions. The box tree is threatened continuously throughout the May to October period. The final generation larvae hibernate inside the box tree and start to feed again for the first time in the next March.
Monitoring der Entwicklung des Buchsbaumzünslers mit TRIPHERON®-Fallen
Zur Befallskontrolle kann der Falterflug durch Pheromonfallen festgestellt werden. Pheromone traps intercept the male moths and can thus partially reduce the fertilization of the females and thus the deposit of eggs. They should be hung up from May onwards. At the beginning of the flight activity, the beginning of larval hatching and thus the necessary treatment time can be calculated.
