Ips cembrae, known generally as larch bark beetle or eight-toothed larch bark beetle, is a species of typical bark beetle in the family Curculionidae. Its habitat is Euro-Siberian, ranging from sea level to sub-alpine. [2] It was first recorded in Great Britain in 1955. [3] Populations were said to be found in Japan and China, but further research determined that those were actually Ips subelongatus. [4]
The insect measures around 5 mm and has a dark brown to black colour. The species is considered hard to distinguish visually from Ips typographus. [4]
Ips cembrae is native to most of its habitat and is considered less of a pest risk than Ips typographus. [1] The beetle mainly affect the European larix, larix decidua, especially during periods of drought. [3] [5] Besides damage from digging tunnels, the beetle also spreads fungi between trees.
The species can be infected by several nematode parasites: Contortylenchus, Parasitylenchus, Cryptaphelenchus and Parasitorhabditis endoparasites, Micoletzkya under the wings as phoretic parasites. Laimaphelenchus and Bursaphelenchus are found in the frass. [6]
