We present evidence favoring the use of (E)-pityol as an aggregation pheromone in Pityophthorus pubescens (Marsham). (E)-Pityol was detected in effluvia of male and female P. pubescens, and antennae of both sexes responded to (E)-( )-pityol in electroantennogram assays. In two-choice olfactometer tests, males significantly preferred (E)-( )-pityol and (E)-(±)-pityol to blank controls at doses of 1, 10, and 100 ng, whereas females only showed a preference for (E)-pityol at the 1 ng dose.
