Pest categorisation of Mimela testaceipes

The EFSA Panel on Plant Health performed a pest categorisation of Mimela testaceipes (Coleoptera: Scarabaeidae), the striated chafer, for the EU, following a commodity risk assessment of dwarfed Pinus parviflora grafted onto P. thunbergii from China in which M. testaceipes was identified as a pest of possible concern to the EU. M. testaceipes occurs in Japan, northeast China, Far East Russia, South Korea and very likely North Korea. Adults are recognised pests feeding on and damaging the needles of Japanese cedar (Cryptomeria japonica), Japanese cypress (Chamaecyparis obtusa) and Japanese larch (Larix leptolepis) which are important forestry trees where the pest currently occurs. It has adapted to feed on the needles of Pinus species introduced into its native area, such as P. taeda, which is native to southeastern USA although M. testaceipes is not regarded as a significant pest of pines. Larvae are reported to cause root damage to grasses, as well as conifers. Eggs are usually laid in grassy soils by females that develop on conifer species. Larvae develop in the soil feeding on the roots of grasses or conifer hosts. Larvae overwinter in the soil and take 2 or 3 years to develop. In principle soil, host plants for planting and cut branches with foliage could provide pathways into the EU. However, prohibitions on the import of soil and hosts such as Chamaecyparis, Larix and Pinus regulate such pathways into the EU. Nevertheless, certain dwarfed Pinus spp. from Japan are provided with a derogation for entry into the EU. In addition, the host C. japonica is unregulated and could also provide a pathway. Hosts occur in the EU in climate zones that match those where M. testaceipes occurs in Asia. If M. testaceipes were to enter the EU, conditions in central and northern EU are conducive to establishment. Following establishment, impacts on Japanese cedar, Japanese cypress and Japanese larch would be expected; it is possible that M. testaceipes could adapt to feed on Pinus and Larix species growing in Europe. M. testaceipes satisfies the criteria that are within the remit of EFSA to assess for it to be regarded as a potential Union quarantine pest.
