The bark beetles of the genus Dendroctonus feed on phloem that is a nitrogen-limited source. Nitrogen fixation and nitrogen recycling may compensate or alleviate such a limitation, and beetle-associated bacteria capable of such processes were identified. Raoultella terrigena, a diazotrophic bacteria present in the gut of Dendroctonus rhizophagus and D.

The Canadian Entomologist, 2002
AbstractThe meiotic formula of the European spruce beetle, Dendroctonus micans (Kugelann), is 10 AA + Xyp in males and 10 AA + XX in females. This karyotype is different from the morphologically similar Dendroctonus punctatus LeConte (14 AA + Xyp), which is consistent with the taxonomic validity of both species. The chromosome number found in D. micans,

Dendroctonus valens LeConte, the red turpentine beetle (RTB) is an invasive pest which is severely threatening pine species in China. Traditional pheromone-based RTB monitoring depends on a manual count, which is not only time consuming but also error ...

Hydrocarbon biosynthesis in insects involves the elongation of fatty acyl-CoAs to very-long chain fatty acyl-CoAs that are then reduced and converted to hydrocarbon, with the last step involving the oxidative decarbonylation of an aldehyde to hydrocarbon

Integrated management of Dendroctonus micans in the UK
Forest Ecology and Management, 1994Abstract Great spruce bark beetle, Dendroctonus micans , first discovered in the UK in 1982, has been the subject of an integrated pest management (IPM) programme developed by the Forestry Commission. The programme is based on acombination of forest management practice, including sanitation felling and restriction of transport of infested spruce ...

Specificity of population-aggregating pheromones in Dendroctonus
Journal of Insect Physiology, 1969Abstract In Dendroctonus the production of population-aggregating pheromones is not specific to sex or species. Aggregation is largely maintained by the specificity of olfactory receptor systems.

From 1979 to 1981, the number of ponderosa pines attacked by Dendroctonus valens LeConte was monitored in conjunction with a series of experiments on Dendroctonus brevicomis LeConte. During these experiments, over 100 trees were baited with D. brevicomis pheromone.
