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 …
