Abstract Electroantennograms were obtained fromD. pseudotsugae in response to the pheromones 3-methylcyclohex-2-en-1-one (3,2-MCHone), 3-methylcyclohex-2-en-1-ol (3,2-MCHol), frontalin,trans-verbenol, verbenone, and the host terpene hydrocarbons limonene and camphene. Male and female beetles were 10 and 100 times more sensitive to 3,2-MCH-one and 3,2-MCHol than to the other compounds. Of the other compounds, males were most sensitive totrans-verbenol, verbenone, and camphene, while females were most sensitive to frontalin, limonene, and camphene. The results parallel and help explain behavior of individual males and females during host tree selection, aggregation, and colonization.
