Assessing cultivar-specific susceptibility and morphological adaptations of Bactrocera oleae (Diptera: Tephritidae) in olive orchards.

The olive fruit fly, Bactrocera oleae (Rossi), is the most important widespread pest in olive-growing areas worldwide, causing significant yield losses and deterioration of olive oil quality. This study hypothesized that olive cultivars differ in their susceptibility to B.oleae and that the cultivar in which the pest develops may affect population variability.
