For the first time, the small gray longhorn tianniu was intercepted at the Chongqing port, which is an alien harmful species

On July 25, the upstream news reporter learned from Chongqing Customs that during the unpacking and inspection of a batch of European boxwood panel containers from Poland at the Inch Beach Port, several tianniu and other harmful organism carcasses were intercepted, which were identified as small gray longhorn tianniu Akanhocinusgriseus and European pine bark elephants, of which the small gray longhorn tianniu was intercepted for the first time at the Chongqing port.

According to Chongqing Customs, the small gray long-horned tianniu belongs to the coleoptera, tianniu family, the subfamily of the gully tibia tianniu, and the genus longhorn tianniu, mostly distributed in Russia, North Korea, Finland and other places, and is distributed in parts of northern China.

Small gray long-horned tianniu mostly parasitizes coniferous broad-leaved tree species such as red pine, ichthyosis pine, fir, spruce, oil pine, larch, walnut, quercus, etc.; spawn in the coniferous trunks of new dead trees or felled trees in early June every year, and the larvae obtain nutrients by eating the phloem of the trunk, and the adult worms drill holes in May of the following year, directly endangering the health of the trees and causing huge losses to the forestry.
