Webbeetles can produce pheromone components and complete development in the bolts from introduced range at levels similar to those in known MPB hosts. We also determined whether chemotypes based on phloem monoterpene profiles of Scots pine popula-tions in Canada affect beetle pheromone production and biological development. Materials and … WebNov 9, 2006 · Bark beetles use monoterpenoid aggregation pheromones to coordinate host colonization and mating. These chemical signals are produced de novo in midgut cells via the mevalonate pathway, and pheromone production may be regulated by a negative feedback system mediated through the antennae.
