Fortifying the forest: Thinning and burning increase resistance to a bark beetle outbreak and promote forest resilience

Publications Posted on: September 30, 2016
Fire frequency in low-elevation coniferous forests in western North America has greatly declined since the late 1800s. In many areas, this has increased tree density and the proportion of shade-tolerant species, reduced resource availability, and increased forest susceptibility to forest insect pests and high-severity wildfire.

Red turpentine Dendroctonus valens P450s: Diversity, midgut location, and response to alfa-pinene enantiomers

Bark beetle colonization action is a biotic stress to the host, which responds to this action by secreting oleoresin. This mixture of several compounds can be highly toxic for the insects. We hypothesized that the first physiological reaction of the insects to these toxic compounds is to metabolize and subsequently use some of them as pheromone precursors.
