The attraction of Scolytus scolytus (F.) to the four enantiomers of 4-methyl-3-heptanol, the major component of the aggregation pheromone, was studied in the field. Only the ()threo isomer attracted significantly more beetles than the blank (control), and the response to this isomer was not significantly different from the response to commercial 4-methyl-3-heptanol, which contains all four isomers. There was no evidence for inhibition of attraction by the other three isomers. Commercial 4-methyl-3-heptanol could therefore be used, in combination with other components of the aggregation pheromone, for population sampling and control by mass trapping of S. scolytus.
