Pheromone producing males of the two subspecies, Ips amitinus and Ips amitinus var. montana, respectively, are fully cross-attractive to field populations of both subspecies and produce identical patterns of male-specific terpene alcohols upon feeding in the phloem tissue of their respective host trees, Picea abies and Pinus cembra: major amounts of ipsdienol along with lesser amounts of amitinol, cis-, trans-verbenol, myrtenol and traces of ipsenol. The absolute configuration of ipsdienol and ipsenol produced by feeding I. a. montana males was determined by gaschromatographic enantiomer separation of the natural products as (S)-(+)-ipsdienol and (S)-(-)-ipsenol, respectively. After joining the males, females release 2-methyl-3-butene-2-ol which is produced by males only in trace amounts
