The susceptible hosts are 44 species of pines, Cedrus libani, C. atlantica and Picea glauca. However, the susceptibility varies a lot among provenances and/or environmental conditions (EPPO, 2024; Tubby et al., 2023). The occurrence of pine hybrids complicates the approach to the list of host species, therefore van der Nest et al. (2019) mentioned 53 different species and hybrids of pine which can host L. acicola.
