Fruit fly

Systematically, this species belongs to the order Diptera and the family Tephritidae (fruit flies). These insects are recognized by the intricate, often net-like or spotted patterns on their wings, which are a defining characteristic of this family.

The larvae of this species primarily feed on plants within the family Asteraceae. The pest is frequently observed on various types of thistles and other composite-flowered plants, specifically targeting the generative structures of these hosts.

The biology of Trupanea femoralis is closely linked to the developmental stages of its host plant. The female deposits eggs directly into the flower heads (capitula) during the budding stage or early flowering. Upon hatching, the larvae burrow into the flower head, where they complete their life cycle by feeding on the internal tissues and developing seeds.

The damage caused is primarily manifested through the deformation of flower heads, inhibition of seed development, and a reduction in seed viability. In cases of high infestation, the pest can significantly decrease yield, which is particularly detrimental for medicinal crops or seed production within the Asteraceae family.

Control measures combine cultural and chemical practices. Crucial steps include the timely removal of weeds that serve as reservoirs for the pest. In cases of high pest pressure, systemic insecticides are applied during the budding stage, and crop rotation is recommended to disrupt the life cycle and reduce the local population density.
