Matsucoccus matsumurae (Kuwana, 1905) - (Japanese pine bast scale, red pine scale)

This scale insect is native to Japan and has been accidentally introduced into China, Korea, Sweden, and eastern North America. It causes serious outbreaks in some areas. For example, in China, where it was introduced in the 1940s, a total of > 300,000 km² of pine forests had been heavily damaged by 1990, and about one third of the trees had to be cut down. Heavily damaged trees show wilting, defoliation and often tree death.

Several pine species are infested, but in North America only red pine (Pinus resinosa) is attacked. In Japan, native pine species show a degree of resistance to the scale (McClure, 1985). The scales live mainly in bark crevices, sucking the sap from the phloem. The adult female is around 3-4 mm long.
