Monoterpene composition and emission rates differed between the two groups, both during daytime and early evening, with a high presence of limonene in infested trees and dominance of pinene-type compounds in non-infested trees.<br \/>\n<strong>Conclusion<\/strong> This work evidenced differences in foliar monoterpene emissions between <em>Q. suber<\/em> trees highly infested by <em>C. welensii<\/em> and non-infested trees, with a high presence of limonene in the former and dominance of pinene-type compounds in non-infested trees. We hypothesize that the detection\u2014especially during the onset of insects daily flight\u2014of certain compounds (e.g., limonene), together with the detection of specific ratios of several monoterpenes (e.g., those of limonene to pinene-type compounds), has a role in the intraspecific host selection by <em>C. welensii<\/em>.<\/p>\n<p><strong>Keywords<\/strong><br \/>\nDehesa, Woodborer, Limonene, Pinene-type, Quercus decline<\/p>\n<div class='altmetric-embed' data-badge-type='donut' data-doi='10.1007\/s13595-019-0879-y'  style='float: right; ' ><\/div>\n<p><strong>Publication<\/strong><br \/>\nS\u00e1nchez-Osorio, I., L\u00f3pez-Pantoja, G., Tapias, R. et al.
