Although several species of the family Scolytinae have been reported as vectors of this pathogen, the role of the pine shoot beetle <em class=\"EmphasisTypeItalic \">T. piniperda<\/em> remains unclear. The general objective of this study was to determine whether <em class=\"EmphasisTypeItalic \">T. piniperda<\/em> is a vector for the pitch canker pathogen <em class=\"EmphasisTypeItalic \">F. circinatum<\/em>. For this purpose, Leach\u2019s postulates (1) an association between <em class=\"EmphasisTypeItalic \">T. piniperda<\/em> and trees affected by pitch canker disease; (2) regular visits by <em class=\"EmphasisTypeItalic \">T. piniperda<\/em> to healthy <em class=\"EmphasisTypeItalic \">P. radiata<\/em> trees; (3) presence of the pathogen on the insect in nature; and (4) transmission of the pathogen to disease-free host material under controlled conditions. Fresh green shoots with feeding galleries were collected from the ground, breeding galleries were collected from diseased trunks and insects were collected during their dispersion flights. A laboratory experiment was conducted in which specimens of <em class=\"EmphasisTypeItalic \">T. piniperda<\/em> were inoculated with the pathogen prior to feeding on shoots. In the field, <em class=\"EmphasisTypeItalic \">T. piniperda<\/em> was found to be associated with both diseased and healthy <em class=\"EmphasisTypeItalic \">P. radiata<\/em> trees, and <em class=\"EmphasisTypeItalic \">F. circinatum<\/em> was found to be present, at low rates, on the exoskeleton of <em class=\"EmphasisTypeItalic \">T. piniperda<\/em>. In the laboratory experiment, evidence of the ability of <em class=\"EmphasisTypeItalic \">T. piniperda<\/em> to transfer the pathogen to healthy shoots was found. The study findings indicate <em class=\"EmphasisTypeItalic \">T. piniperda<\/em> as a plausible vector of this pathogen. We postulate for the first time a potential relationship between the life cycles of <em class=\"EmphasisTypeItalic \">T. piniperda<\/em> and <em class=\"EmphasisTypeItalic \">F. circinatum<\/em>.<\/p>\n<div class='altmetric-embed' data-badge-type='donut' data-doi='10.1007\/s13595-015-0515-4'  style='float: right; ' ><\/div>\n<\/div>\n<p><em>Publication<\/em><\/p>\n<p style=\"text-align: justify\">Bezos D, Mart\u00ednez-\u00c1lvarez P, Diez J, Fern\u00e1ndez M 2015.
