Euwallacea fornicatus

Euwallacea fornicatus The phylogenetic tree generated from our analyses (Figure 3) revealed that the majority of Euwallacea species clustered into four main clades, consistent with the findings of Gómez et al. (2018) and Smith et al. (2019). The 12 samples from Spain are nested together with all the PSHB clade, assigned to E. fornicatus by Smith et al. (2019). A single haplotype was identified in the Spanish samples, distinct from the H33 haplotype reported in Israel, the USA, and South Africa (Stouthamer et al. 2017). Phylogenetically, our samples may be more closely related to haplotypes found in Japan, China, and Vietnam. A total of 241 specimens of E. fornicatus have been captured in the trap network in Motril, between early June and early November 2024 (Table 1, Figure 1). Additionally, infestations were detected in ornamental A. negundo (17 infested trees) and P. aculeata (1 infested tree). In October 2023, infestations were also detected in three orchards of P. americana (Lauraceae) and in Ricinus communis L. (Euphorbiaceae) (CAPADR 2024). Local authorities are implementing measures to eradicate the outbreak in accordance with national and European plant protection regulations.
