Pheromone biosynthesis in bark beetles
Current Opinion in Insect Science, 2017Pine bark beetles rely on aggregation pheromones to coordinate mass attacks and thus reproduce in host trees. The structural similarity between many pheromone components and those of defensive tree resin led to early suggestions that pheromone components are metabolic derivatives of ingested precursors.

Predation and bark beetle dynamics
Oecologia, 1997Bark beetle populations may undergo dramatic fluctuations and are often important pests in coniferous forests. Their dynamics are thought to be primarily driven by factors affecting the resistance of the host tree to attack, i.e., bottom-up forces, while natural enemies are usually assigned a minor role in these systems.

THROUGHOUT the summer and early autumn, small piles of white bore dust on the surface of the bark of ash, English or imported, are a common sight in timber yards and dispersal sites. As the Forest Products Research Laboratory receives a number of inquiries every year on this type of insect attack, the following information may be useful to all who may ...
