Literature searches were undertaken by EFSA to complete the knowledge gaps concerning (i) the pest Agrilus planipennis, mostly with reference to larval density and adult emergence; (ii) the fumigant sulfuryl fluoride, mostly with reference to its efficacy against A. planipennis and other wood boring beetles in all stages of development; and (iii) the commodities of ash logs with bark and debarked ash logs.
Systematic literature review on points (i) and (ii) was performed applying an ad hoc search string run between April and May 2022. In Appendix B, the search strategy, results and an extraction table summarising the main evidence are provided.
Additional searches, limited to retrieve documents, were run when developing the opinion. The available scientific information, including previous EFSA opinions on the relevant pest and relevant fumigant (e.g. EFSA, 2020 (link); EFSA PLH Panel, 2020 (link)), was considered.
