Short pest overview:
Adults are very large insects with bodies ranging from 1,7 cm to 3,9 cm (0,67 in to 1,54 in) in length and antennae which can be as long as 4 cm (1,6 in) or 1,5-2 times longer than the body of the insect. Due to high tree mortality caused by larval feeding outside its native range, Anoplophora glabripennis can change both forest and urban ecosystems. It infests plants like maple, poplar, willow and elm trees and others.
The native range of the Asian longhorned beetle is Eastern Asia, primarily in Eastern China and Korea. But it is invasive outside its native range. Its populations were discovered in North America, Europe.
Adult specimens can be found between April and December, but the most active period for adult activity is late June to early July, and oviposition most often occurs in early summer. About 45-62 eggs are laid one by one by females. The life cycle can last up to 1-2 years. Eggs, larvae or as pupae can overwinter within the tree. Larvae first create a feeding gallery in the cambial region, but more mature larvae tunnel to the heartwood as they feed.
