While the species is highly susceptible to Dutch elm disease, [20] [21] it is less favoured as a host by the elm bark beetles, which act as vectors. Research in Spain has indicated the presence of a triterpene , alnulin , rendering the tree bark less attractive to the beetle than the field elm , though at 87 μg/g dried bark, its concentration ...
