“…Diverging reports are given concerning the importance of both ethanol and c~-pinene alternately ethanol alone for the attraction of T. lineatum to the host (Vit6 & Bakke, 1979;Klimetzek et al, 1980;Borden et al, 1981Borden et al, , 1982. The proportion of host odour cells corresponded to that observed in other bark beetle species which, like the bark beetle, also have a few cells exclusively responding to the non-host, birch.…”

In the ambrosia beetle Trypodendron lineatum (Oliver) (Coleoptera: Scolytidae) a large number of olfactory receptor cells were identified keyed to the pheromone (+)-lineatin. No cell responding to pheromones adhering to other bark beetle genera was found. This indicates that T. lineatum do not benefit from recognizing other bark beetle species when colonizing a host. The results support previous field results that e-pinene and ethanol are signals of significance for T. lineatum. However, concerning c~-pinene it should not be excluded that an other component might instead be the key odour.Results obtained by the combined gas chromatographical (GC) separation with electrophysiological single cell recordings, suggested that host odour cells respond to one or a few compounds and that minor constituents are rather important. Selective responses of a few cells to non-liost volatiles further suggest that such signals may play a role as repellents or inhibitors when the beetles search for a host.

Pine monoterpenes and pine bark beetles: a marriage of convenience for defense and chemical communication

et al. 2006

Pine-feeding bark beetles (Coleoptera: Scolytidae) interact chemically with their host pines (Coniferales: Pinaceae) via the behavioral, physiological, and biochemical effects of one class of isoprenoids, the monoterpenes and their derivatives. Pine monoterpenes occur in the oleoresin and function as behaviorally active kairomones for pine bark beetles and their predators, presenting a classic example of tritrophic chemical communication. The monoterpenes are also essential co-attractants for pine bark beetle aggregation pheromones. Ironically, pine monoterpenes are also toxic physiologically to bark beetles at high vapor concentrations and are considered an important component of the defense of pines. Research over the last 30 years has demonstrated that some bark beetle aggregation pheromones arise through oxygenation of monoterpenes, linking pheromone biosynthesis to the host pines. Over the last 10 years, however, several frequently occurring oxygenated monoterpene pheromone components (e.g., ipsenol, ipsdienol and frontalin) have also been shown to arise through highly regulated de novo pathways in the beetles (reviewed in Seybold and Tittiger, 2003). The most interesting nexus between these insects and their plant hosts involves the latestage reactions in the monoterpenoid biosynthetic pathway, during which isomeric dimethylallyl diphosphate and isopentenyl diphosphate are ultimately elaborated to stereospecific monoterpenes in the trees and to hydroxylated monoterpenes or bicyclic acetals in the insects. There is signal stereospecificity in both production of and response to the monoterpenoid aggregation pheromones of bark beetles and in response to the monoterpenes of the pines. In the California fivespined ips, Ips paraconfusus, we Dedicated to Professor David L. Wood on the occasion of his 75th birthdayÓ Springer Science+Business Media B.V. 2006have discovered a number of cytochome P450 genes that have expression patterns indicating that they may be involved in detoxifying monoterpene secondary metabolites and/or biosynthesizing pheromone components. Both processes result in the production of oxygenated monoterpenes, likely with varying degrees of stereospecificity. A behavioral analysis of the stereospecific response of I. paraconfusus to its pheromone is providing new insights into the development of an efficacious bait for the detection of this polyphagous insect in areas outside the western United States. In contrast, a Eurasian species that has arrived in California, the Mediterranean pine engraver, Orthotomicus (Ips) erosus, utilizes both a monoterpenoid (ipsdienol) and a hemiterpenoid (2-methyl-3-buten-2-ol) in its pheromone blend. The stereospecificity of the response of O. erosus to the monoterpenoid appears to be the key factor to the improved potency of the attractant bait for this invasive species.

“…The data were transformed to log,, The response of T. lineutum to its pheromone is similar to that of Dendroctonus brevicomis Le Conte which responds to ( +)-em-brevicomin and (-)-frontalin, and is not inhibited by the presence of the antipodes of either (WOOD et al 1976). It is unlike that of other ambrosia beetles, such as Gnathotrichus sulcutus Le Conte, for which the two enantiomers of sulcatol are synergistic (BORDEN et al 1976), or G. retusus Le Conte which responds to S-( +)-sulcatol and is inhibited by the R-(-) enantiomer (BORDEN et al 1980b;1981).…”

In a field experiment in England, Trypodendron lineatum (Olivier) responded positively to traps baited with (±) or (+)‐4,6,6‐lineatin (3,3,7‐trimethyl‐2,9‐dioxatricyclo [3.3.1.04,7] nonane). There was a trace positive response to (‐)‐4,6,6‐lineatin, possibly due to (+)contamination, but no response to (±)‐4,5,6‐lineatin. The data indicate that the response of English T. lineatum is almost identical to that of continental European and North American beetles, and suggest that (±)‐4,6,6‐lineatin (lineatin) can be used with confidence as a pest management tool throughout the range of the species. Zusammenfassung Reaktion von Trypodendron lineatum (Ol.) auf Isomeren seines Aggregationspheromons Lineatin in England Bei Freilandversuchen reagierte T. lineatum positiv auf mit (±) oder (+)‐4,6,6‐Lineatin bestückte Fallen. Es gab eine schwache positive Reaktion auf (‐)‐4,6,6‐Lineatin, möglicherweise aufgrund einer (+)‐Kontaminierung, jedoch keine Reaktion auf (±)‐4,5,6‐Lineatin. Die Ergebnisse zeigen, daß die Reaktion englischer T. lineatum nahezu identisch mit den kontinental europäischen und amerikanischen Käfern ist und daß (±)‐4,6,6‐Lineatin (“Lineatin”) zur Schädlingsbekämpfung innerhalb der Artengruppe verwendet werden kann.
