Morphometric differentiation among anastrepha fraterculus (diptera: Tephritidae) exploiting sympatric alternate hosts

Anastrepha fraterculus (Wiedemann) is currently considered a complex of cryptic species infesting fruits from Mexico to Argentina and represents an interesting biological model for evolutionary studies. Moreover, detecting and quantifying behavioral, morphological, and genetic differentiation among...
