Canada and the Netherlands have adopted the International Standard for Phytosanitary Measures (ISPM) No. 15 for Wood Packing Materials (WPM). This measure reflects the necessity of a heat- or a chemical (Methyl Bromide) treatment of wood thicker than 6 mm and is approved by the International Plant Protection Convention (IPPC). Prior to use WPM should be properly treated and debarked to prevent the spread of live plant pests and diseases, especially Quarantine species. WPM treated according to ISPM 15 is marked, but these measures are not always properly implemented. Interceptions by the plant protection services of Canada and the Netherlands of living insects, such as larvae of Cerambycidae, occurs regularly in WPM during import inspections at airports, at harbours or at stone-importing companies. Living larvae of Cerambycidae have been intercepted in wood from numerous tree species, both coniferous and deciduous trees, in particular those used for the transport of stone and tiles from China. In addition to wood packaging, handicrafts manufactured from wood are also a pathway for live Cerambycid larvae.
