Ethanol as the primary attractant for the ambrosia beetle trypodendron lineatum (coleoptera: scolytidae)
TLDR
In laboratory bioassays, ethanol was attractive at low concentration to both sexes of Trypodendron lineatum (Olivier), and monoterpenes had a repellent effect on T .Abstract:
Methanol, acetaldehyde, and ethanol have been identified in extracts of attractive wood and bark. The attractancy induced by anaerobic treatment in both sapwood and phloem of conifers and broadleaf trees was characterized by ethanol as the most concentrated component. In laboratory bioassays, ethanol was attractive at low concentration to both sexes of Trypodendron lineatum (Olivier). Methanol and acetaldehyde, at the concentrations found, apparently play no role in attraction. Monoterpenes had a repellent effect on T. lineatum.read more

Host odor perception in phytophagous insects
TL;DR: In the present review selection was made mainly from the literature of the last 20 years.

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

Chemical ecology of bark beetles
TL;DR: The regulation of attack density, termination of the aggregation, mechanisms of attack spacing, and recognition of host suitability are presented in the context of an individual's avoidance of intra- and interspecific competition.

Interacting selective pressures in conifer-bark beetle systems: a basis for reciprocal adaptations?
TL;DR: The theory that a synchronous decline in resistance capacity among old trees in even-aged stands increases the likelihood of beetle epidemics and subsequent fires, thereby favoring reestablishment of lodgepole pine is examined.

Host-Tree Chemistry Affecting Colonization in Bark Beetles
TL;DR: A diversity of bark beetle biology, in which each species is adapted to only one or a few host-tree species, has probably resulted from natural selection due to the great variety of trees and their biochemicals.

TL;DR: Inorganic spot test analysis has been extensively studied in the literature, see as discussed by the authors for a survey of the current state and prospects of inorganic inorganic spot-test analysis, including preliminary orientational tests for the elements, their ions and compounds.

Scolytid Beetles Associated with Douglas Fir: Response to Terpenes
TL;DR: Douglas-fir oleoresin and the terpene hydrocarbons (α-pinene, β- pinene, litnonene, camphene, geraniol, and α-terpineol) attracted various bark and timber beetles associated with Douiglas- fir forests during their flight.

TL;DR: Experimental evidence supports a hypothesis that oxygen deficiency may be a causal factor in the formation of chemical attractants for the ambrosia beetle Trypodendron lineatum (Olivier).

Release by Flight Exercise of a Chemotropic Response from Photopositive Domination in a Scolytid Beetle
TL;DR: B barkbeetles and ambrosia beetles show a strong preference for logs that have ‘ripened’ for a period of some weeks or months after being-felled.
