Thirty-five populations ofIps pini (Say) and one population each ofIps avulsus (Eichhoff) andIps bonanseai (Hopkins) were analyzed for the enantiomeric composition of ipsdienol (2-methyl-6-methylene-2,7-octadien-4-ol). Populations ofI. pini occur as at least two distinct regional pheromone variants: New York type [32%-(−) to 56%-(−)-ipsdienol] and California type [94%-(−) to 98%-(−)-ipsdienol]. A third phenotype may occur in southeastern British Columbia, Idaho, and Montana [91%-(−) to 95… Expand

TLDR
It is hypothesized that the Idaho race, which does not compete withI. Expand
Genetic Control of the Enantiomeric Composition of Ipsdienol in the Pine Engraver, Ips pini
TLDR
Dominance at one autosomal locus explains much of the variation in ipsdienol blend between the divergently selected lines, as in all previously studied female long-range pheromone systems, a major genetic element is implicated. Expand
Cuticular Hydrocarbons as Chemotaxonomic Characters of Pine Engraver Beetles (Ips spp.) in the grandicollis Subgeneric Group
TLDR
Several phylogenetic analyses based on hydrocarbon phenotypes agreed in general with the established morphologically based system of relatedness and with published phylogenies reconstructed from protein and nucleic acid characters. Expand
Variation in Enantiospecific Attraction of Ips avulsus (Coleoptera: Curculionidae) to the Pheromone Ipsdienol in Georgia
TLDR
The observed variation in enantiospecific responses of I. avulsus to ipsdienol may be explained by variation in semiochemical context (i.e., different co-baited among the experiments) or seasonal variation. Expand
Aggregation Pheromone of Pityogenes knechteliand Semiochemical-Based Interactions with Three Other Bark Beetles
TLDR
The results suggest that ipsenol and ipsdienol serve as synomones involved in promoting aggregation on the host tree, maintaining species-specific communication, and thus contributing to resource partitioning and reduced competition among the four species. Expand
Elucidating pheromone and host volatile components attractive to the spruce beetle, Dendroctonus rufipennis (Coleoptera: Curculionidae), in eastern Canada
TLDR
Frontalin and seudenol alone or spruce terpene blend and ethanol alone typically had among the lowest trap catches, but when combined they caught the highest numbers of D. rufipennis, supporting the hypothesis that host volatiles synergise attraction to pheromones. Expand
Reproductive Isolation of Ips nitidus and I. shangrila in Mountain Forests of Western China: Responses to Chiral and Achiral Candidate Pheromone Components
TLDR
Two fully factorial experiments demonstrated that (±)-Id, cV, and 2-methyl-3-buten-2-ol (MB) are components of the aggregation pheromone of I. nitidus, whereas only (+)-Id and cV are essential components ofThe aggregation phersomone is reviewed to show that cV is more common than methylbutenols, and both elicit qualitatively variable responses.

Attraction of Ips pini (Coleoptera: Scolytinae) and Its Predators to Natural Attractants and Synthetic Semiochemicals in Northern California: Implications for Population Monitoring
TLDR
The results suggest that preferences of bark beetles and predators for bark beetle pheromones at the regional scale should be considered before deploying semiochemicals, and the roles of plant volatiles should be further investigated. Expand
Assessment of genetic and pheromonal diversity of the Cydia strobilella species complex (Lepidoptera: Tortricidae)
TLDR
This study demonstrates the great potential of using pheromone trapping as a tool for identification and delimitation of taxa within cryptic species complexes. Expand
Functional expression of a bark beetle cytochrome P450 that hydroxylates myrcene to ipsdienol.
TLDR
Quantitative real-time PCR experiments showed that feeding on host phloem induced CYP9T2 expression in males, but not females, and that basal expression levels are highest in male midguts, similar to other I. pini pheromone-biosynthetic genes. Expand

The role of lanierone in the chemical ecology ofIps pini (Coleoptera: Scolytidae) in California
TLDR
Five doses of lanierone (2-hydroxy-4,4,6-trimethyl-2,5-cyclohexadien-1-one) were tested with one dose of enantiomerically pure ipsdienol for activity as an aggregation pheromone ofIps pini (Say) in California, proving synergism for the kairom one of this predator. Expand

TLDR
A new pheromone component, lanierone, was isolated and identified from a Porapak Q collection of volatiles from maleIps pini from New York through GC fractionation, bioassay, and spectrometry and is produced exclusively by males. Expand

In breeding experiments the plastograpbus subspecies were fully interfertile but fertility of backcross and F2 generations was reduced, and results were different for the reciprocal pairings and the backcrosses showed increased fertility, which defy explanation by nuclear genetics but may result from cytoplasmic incompatibility.

TLDR
Significant deficiencies exist in the understanding of the role of enantiomeric composition in pheromonal/allomonal effects in different subgeneric groups, in the regulation and mechanisms of stereoselective biosynthesis of the monoterpene alcohols, and in the benefits derived by individual insects that produce relatively large proportions of inactive or interruptive enantiomers with attractiveEnantiomers.
