The EURL for Insects and Mites carries out pre-testing studies of tests/diagnostic protocols published in scientific revues. The aim of this activitiy is to select the best performing test and to submit it to a full validation study. This is done for regulated pests for which no reference diagnostic protocols are available such as those published in international or regional standards by the International Plant Protection Convention (IPPC) or the European and Mediterranean Plant Protection Organization (EPPO). Please note that tests subject to pre-testing are not to be considered as recommended by EURL under any circumstances. Only a full validation study can lead to a recommendation for use.
