Description: Female white pine cone beetles, Conophrhorus coniperda, attacking second-year cones of eastern white pine, Pinus strobus L., produced a sex-specific pheromone that attracted conspecific males in laboratory bioassays and to field traps. Beetle response was enhanced by host monoterpenes. The female-produced compound was identified in volatiles collected on Porapak Q and in hindgut extracts as (+)-trans-pityol, (2R,5S)-(+)-2-(1-hydroxy-1-methylethyl)-S-methyltetrahydrofuran. Males and females produced and released the (E)-( -)-spiroacetal, (5S,7S)-(-)-7-methyl-1,6-dioxaspiro-[4.5]decane, which was not an attractant for either sex, but acted as a repellent for males. Porapak Q-trapped volatiles from both sexes contained (+)-trans-pinocarveoland (-)-myrtenol.In addition, hindgut extracts of females contained trans-verbenol,while males had pinocarvone and verbenone. Work in Georgia and Canada confirmed that the same isomers of pity01 and spiroacetal are present in two distinct and widely separated populations of C. coniperda.
