Disruptive selection maintains variable pheromone blends in the bark beetle Ips pini.

Environmental entomology - 1 Dec 2011

Shumate Alice M, Teale Stephen A, Ayres Bruce D, Ayres Matthew P

Abstract excerpt

The presence of heritable variation is a prerequisite for evolution, but natural selection typically reduces genetic variation. Variation can be maintained in traits under selection through spatial or temporal variation in fitness surfaces, frequency-dependent selection, or disruptive selection. We evaluated the maintenance of variation in the enantiomeric blend of pheromones employed by the bark beetle Ips pini...
