Journal ArticleDOI
Climate Change and Bark Beetles of the Western United States and Canada: Direct and Indirect Effects
Barbara J. Bentz,Jacques Régnière,Christopher J. Fettig,E. Matthew Hansen,Jane L. Hayes,Jeffrey A. Hicke,Rick G. Kelsey,Jose F. Negron,Steven J. Seybold +8 more
TL;DR: A synthesis of climate change effects on native bark beetles, important mortality agents of conifers in western North America, is provided and a movement of temperature suitability to higher latitudes and elevations is suggested.
Journal ArticleDOI
Insect pheromones—an overview of biosynthesis and endocrine regulation
TL;DR: A molecular level understanding of the regulation of insect pheromone biosynthesis is in its infancy, and in the male California fivespined ips, Ips paraconfusus (Coleoptera: Scolytidae), JH III acts at the transcriptional level by increasing the abundance of mRNA for 3-hydroxy-3-methylglutaryl-CoA reductase, a key enzyme in de novo isoprenoid aggregation pheromsynthesis.
Journal ArticleDOI
A review of the chemical ecology of the Cerambycidae (Coleoptera)
TL;DR: A brief overview of cerambycid biology, ecology, economic significance, and management is provided and emerging generalities are that attractants tend to be monoterpenoids and phenolic esters; oviposition stimulants are monoterPenoids and flavanoids; short-range sex pheromones are female-produced, methyl-branched cuticular hydrocarbons; and long-rangesex pheramones are male-produced α-hydroxy ketones
Journal ArticleDOI
Pine monoterpenes and pine bark beetles: a marriage of convenience for defense and chemical communication
Steven J. Seybold,Dezene P. W. Huber,Dezene P. W. Huber,Dezene P. W. Huber,Jana C. Lee,Jana C. Lee,Andrew D. Graves,Jörg Bohlmann +7 more
TL;DR: In the California fivespined ips, Ips paraconfusus, 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 are discovered.
Journal ArticleDOI
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.
