The East Asian longhorn beetle (Anoplophora chinensis) is indigenous in Asia but is nowadays found in countries all over the world as result of the international trade in wood and plants. The beetle has also a few times been found in Belgium and the Netherlands; in January 2010 the species hit the news after earlier observations of larvae in the Boskoop nursery stock centre.

Climate change causes exotic fungi, bacteria and insects to thrive in Europe. This necessitates the immediate identification and destruction of such harmful organisms. Scientists of Plant Research International are working on an effective identification of the organisms.

Each month many new types of fungi, bacteria or insects are entering Europe. They are coming along with the worldwide trade in plants and plant products and the higher temperatures resulting from climate change mean that they are thriving better.

Part of these organisms are harmful to plants and crops. Governments are enforcing a strict phytosanitary policy to protect plant health.


The European Union has a so-called quarantine list of 300 species that may not enter the EU. Any batch of imported material in which the inspection service finds an organism from this list will be destroyed. Exporting countries are also keeping a close eye on those quarantine organisms.

Recognition of the species, however, is not always easy. Some are so closely related to species that are not harmful that the differences can not always be seen, even under a microscope. This is why our scientists are in the EU QBOL project cooperating with scientists from all over the world on the detection of these organism on basis of DNA. They determine which DNA fragment is characteristic in distinguishing one species from another. Meanwhile, American, Canadian, Australian and New Zealand services are also showing an interest in the development of this method for identifying their quarantine organisms.
