Pest categorisation of non‐EU Scolytinae on non‐coniferous hosts

open access: yesEFSA Journal, Volume 22, Issue 9, September 2024.
Abstract The EFSA Panel on Plant Health performed a group pest categorisation for the EU territory of non‐EU Scolytinae (Coleoptera: Curculionidae) on non‐coniferous hosts, which total 6495 known species. Most species attack apparently healthy, weakened or dead trees, either feeding on the phloem (‘bark beetles’ subgroup) or on fungi inoculated into ...

Clonal genomic population structure of Beauveria brongniartii and Beauveria pseudobassiana: Pathogens of the common European cockchafer (Melolontha melolontha L.)

open access: yesEnvironmental Microbiology, Volume 26, Issue 4, April 2024.
We investigated the population genomic structure of the fungal pathogens Beauveria brongniartii and B. pseudobassiana, which were isolated from adult Melolontha melolontha beetles. We conclude that the genomic population structure of Beauveria spp. is primarily influenced by widespread clonal reproduction and long‐distance dispersal. Abstract Beauveria
