[Summary of Invasiveness]

L. monacha is considered to be the number one forest pest in Poland because of the unprecedented economic losses it causes in spite of intensive chemical protective treatments on an area of 6.3 million ha of pine, spruce and other conifers between 1978 and 1984 (Sliwa and Sierpinski, 1986). It is also considered to be a major pest in all the other areas where it goes through periodic outbreaks causing defoliation and resulting in the death of spruce and pine trees (Bejer, 1988). The frequency of outbreaks has increase from about every 30 to 40 years to intervals of 6 years. It poses an ever present threat of being accidentally transported via commerce and introduced into other world areas, where susceptible hosts are present. This is because the adults are readily attracted to artificial lights and have been observed in Russian Far East ports (Munson et al., 1995), and although the eggs are normally laid in bark crevices, they could also be deposited in crevices on containers, pallets, ships, etc. In a pest risk assessment for importation of larch from Siberia into the USA, L. monacha was one of the serious pests that were considered at risk of introduction if the bark was still on the logs, because of their use of the bark for oviposition and the fact that the eggs are not readily visible (Anonymous, 1991).
