DescriptionFlow of constitutive oleoresin is believed to be a major component of tree defense against attack by the southern pine pine beetle (Dendroctonus frontalis Zimmermann). Pines that exude large quantities of oleoresin are considered to be most capable of preventing or obstructing colonization by this destructive insect herbivore (Hodges et al. 1979; Cook and Hain 1987; Strom et al. 2002). We evaluate a tree's capacity to resist attack by assessing resin yield over a fixed time interval from one or more small wounds made on a tree's bole or at or near breast height. These wounds are administered so as to a sample resin from a zone proximal to the bark, the region containing tissues directly affected by D. frontalis during an attack. From resin yield measured in this way, it is desirable to determine the relative contribution of variation among multiple measurements taken from individual trees compared to phenotypic variation existing in populations.
