Red Turpentine Beetle Dendroctonus valens LeConte
2017The red turpentine bettle (RTB), Dendroctonus valens LeConte (Coleoptera:Curculionidae: Scolytinae), is a secondary pest of pines in its native ranges in North and Central America. Outbreaks and tree mortality caysed by RTB alone are rare in its native ranges.

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,

Biology of Dendroctonus punctatus (Coleoptera: Scolytidae)
Annals of the Entomological Society of America, 1995The biology of Dendroctonus punctatus LeConte was studied in white spruce, Picea glauca (Moench) Voss, forests of boreal western North America and in the laboratory. Engelmann spruce, P. engelmannii (Parry) Engelmann, was not found to be infested in nature but was used successfully for rearing in the laboratory.

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.

Environmental Entomology, 1983
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.

Dendroctonus pseudotsugae : A Hypothesis Regarding Its Primary Attractant
Science, 1965The Douglas-fir beetle is attracted to α-pinene but repelled by β-pinene. Attacks on standing trees are related to the content of α- or β-pinene in the tree; this correlation suggests that volatile oils may be the stimuli initially attracting the insect to the Douglas fir.
