Analysis of the genetic structure of a natural population of Anastrepha fraterculus (Diptera: Tephritidae)

The South American fruit fly Anastrepha fraterculus (Wiedemann) is distributed from Mexico to northern and central Argentina. It is a polyphagous species using diverse fruit from wild and cultivated tree or shrub species as feeding and breeding sites. During larval stages, the environment is discont...
