Title: Xylem Resin in the Resistance of the Pinaceae to Bark Beetles
Author: Smith, Richard H.
Source: Pacific Southwest Forest and Range Experiment Station, Berkeley, California. 7 p.
Station ID: GTR-PSW-001
Description: Xylem resin of Pinaceae is closely linked with their resistance and susceptibility to tree-killing bark beetles. This review of the literature on attacking adults suggests that all three resistance mechanisms proposed by Painter — preference, antibiosis, and tolerance — are active in this relationship: preference by attraction, repellency, and synergism; antibiosis by both chemical and physical properties; tolerance by healing and secondary resinosis.
Key Words: Pinaceae, insect-host relationships, Scolytidae, resins, terpenes, attractants, antibiosis
