Sakhalin pine sawyer (Monochamus saltuarius) is an insect pest.
Originally a rare Siberian montane species, now found in the spruce forests of Western Hungary. Larvae develop in dying branches high in the tree. At first they feed beneath the bark, later moving into the heartwood to pupate. Monochamus saltuarius is a vector of the pinewood nematode, Bursaphelenchus xylophi. This is just one of many forest pests that are moved to un-infested forests by humans moving firewood. Help to protect our forests: don't move firewood!
