摘要: Abstract Invasive species, including plants, insects and other pests, are a serious threat to agricultural production the environment in general. Finland has traditionally had favourable situation concerning invasives, partly due its isolated geographical location. The may now be changing one of currently increasing threats is Colorado potato beetle (CPB). designed CPB protection policy incorporating protected zone, which commonly used deal with invasive plant pests European countries. Within this randomly occurring invasions collectively fended off, prevent establishment permanent pest population minimise potential damage. This paper evaluates economics current programme, comparing hypothetical pre-emptive abandoned control relies on producers’ individual reactive measures. annual random modelled static stochastic framework. To date not been able establish Finland. According our analysis, exercised cost-efficient choice at point. relatively low expected invasion magnitude key factors supporting efficiency system. Another reason fairly small damage incurred. However, when become larger more frequent or strains cold-resistant, future change.
