Box tree moth, Cydalima perspectalis
The box tree moth is a pest of box trees within the buxaceae family as well as some celastraceae species of tree. These trees are often found in homes and hotel grounds, historical gardens and churches. It occurs in Asia, Europe and North America and has spread through trade of infested host plants. There are three or more generations per year depending on environmental conditions. The larvae overwinter in cocoons spun between its hosts leaves then emerge in spring. High numbers can cause complete defoliation and economic loss. These pests should be monitored with pheromone traps weekly during months when adults are in flight in order to time treatments and reduce crop damage.
