Within this section, <em>E. globulus<\/em> was always the preferred species, while <em>E. nitens<\/em> was the least preferred. Differences in susceptibility were less pronounced at high attack intensity by <em>G. platensis<\/em>. <em>Eucalyptus saligna<\/em> (section Latoangulatae) was the least preferred species among <em>Symphyomyrtus<\/em>. All species from subgenus <em>Eucalyptus<\/em> had low susceptibility to <em>G. platensis<\/em>, particularly <em>E. regnans<\/em>, which was never attacked under field conditions.
