Plain Language Summary

The authors tested the effectiveness of the systems approach in changing the risk posed by wood boring insects might be transported in sawn wood (lumber) sold for export. Systems approaches are way that producers can use to make sure that commodities are free of pests. This tool considers how all the steps of a production process act to reduce the risk of living pest existing in the final product. To test this, the authors used ash trees infested with emerald ash borer to 1) quantify the change in emerald ash borer density as a log is turned into sawn wood (lumber) and 2) quantify the effect of heat treatment on mortality on emerald ash borer pupae in situ. The authors show that the production process removes >99% of emerald ash borer by the time a log is turned into sawn wood, and that heat is effective at killing the insect in the wood, and at lower temperatures than present regulations require.
