The bark beetle, Pityogenes chalcographus, is one of the main pests in Picea abies stands, and it has also been found on other European Pinaceae species. With massive introductions of North American conifer species into European forests, this insect has extended its host range to exotic Pinaceae species. This study assessed whether a wider host range has influenced the genetic structure of P. chalcographus and has led to host specialization. Insects were collected from two different regions of… CONTINUE READING
