Longhorn beetles Anoplophora glabripennis and Anoplophora chinensis are quarantine pests of woody plants, which are, among other routes, spread in wooden pallets and packaging. The methodology describes the effective application of EDN(R) (active substance ethanedinitrile) in the treatment of wooden packaging and untreated wood in order to reduce the risk of the introduction of invasive species of wood-destroying pests (Anoplophora spp.) into the Czech Republic. Quarantine fumigation with methyl bromide is banned in the EU, and the alternative method of heat treatment (ISMP 15) is logistically demanding and cannot be performed in containers or under tarpaulin. The specific objective of the methodology is to provide a technical description of the procedure for the effective application (under tarpaulin / in a container) of EDN(R) to control longhorn beetles A. glabripennis and A. chinensis; the methodology is also prepared as a basis for the possible need for a rapid emergency regulation (ÚKZÚZ - CISTA) for the use in the Czech Republic of Anoplophora spp. longhorn beetles. Another goal is to give a brief overview and evaluation of methods and used products for phyto-quarantine wood treatment in comparison with the new procedure. The methodology is based on original experimental data, which was the basis for determining effective doses of EDN; the doses were expressed as the so-called Ctproduct of concentration and time. Ct- EDN products were determined to a large extent on the model species of longhorn beetle Hylotrupes bajulus (so-called adequate / analogous model species), and then validated for both target species of quarantine longhorn beetles A. glabripennis and A. chinensis. The methodology presents technical specifications and the use of application equipment for the application of liquefied EDN from cylinders using nitrogen as a propellant.
