Phylogenetic-Pheromone Associations Obscured by Stabilising Selection and Natal Tree Effect in a Tree-Killing Bark Beetle.

Abstract excerpt

Insects are highly reliant on chemical cues such as pheromones to facilitate communication and navigation. Some of the roles of pheromones include attracting and finding mates and conspecifics, and in these cases, we expect stabilising selection to dampen within-population pheromone variation. On the other hand, standing pheromone variation may lead to barriers to gene flow and saltational shifts that facilitate...
