Chemotaxonomy of the genus Abies—II : Within tree variation of the terpenes in cortical oleoresin☆
TLDR
The variation of the cortical terpene composition along the stem of eleven trees belonging to four Abies species was examined by GLC methods, and the changes appeared to be the greatest in the youngest part of the stem, before the resin-containing blisters are externally visible.About:

Volatile leaf oil analysis in chemosystematic studies of North American conifers
TL;DR: The chemosystematic results based on leaf oil analysis of northern North American conifers of the families Pinaceae and Cupressaceae are summarized and discussed in relation to known botanical relationships and other chemosSystematic approaches.

Biosynthesis of coniferophagous bark beetle pheromones and conifer isoprenoids: evolutionary perspective and synthesis
TL;DR: This synthesis reveals and evaluates the evolutionary redundancy occurring in the biochemical systems of the insect and host and compares monoterpenoid pheromone biosynthesis in scolytids with monoterpene biosynthesisation in conifers.

Primary Attraction of the Fir Engraver, Scolytus ventralis
Jorge E. Macías-Sámano,John H. Borden,Regine Gries,Harold D. Pierce,Gerhard Gries,G. G. S. King +5 more
TL;DR: It is argued against the hypothesis of pheromone-mediated secondary attraction in S. ventralis and concluded that the attack dynamics of this species can be explained solely by its sensitive primary attraction response to host volatiles.

Analyses of Monoterpenes of Conifers by Gas-Liquid Chromatography
TL;DR: In the literature, these compounds are variously termed "monoterpenes", "terpenes" or "volatile oils", "essential oils", or "turpentine" as discussed by the authors.

Aggregation pheromones of the European fir engraver beetles Pityokteines curvidens, P. spinidens and P. vorontzovi and the role of juvenile hormone in pheromone biosynthesis1
TL;DR: Secondary attraction in the european fir engraver beetles Pityokteines curvidens, P. spinidens and P. vorontzovi, and the role of juvenile hormone in pheromone biosynthesis were examined, suggesting that other secretions from the neuroendocrine complex in the head are required for pherosynthesis to occur.

Perennial Constancy of the Monoterpene Synthesis in the Wood Oleoresin of Pinus ponderosa
TL;DR: No age relationship could be found among the trees, although they covered the age range of the pine, and variation between plot averages was much less than intraspecific variation.
