Which species is classified under the family of weevils?

1. Citrus white fly

2. Plum curculio

3. Rhagoletis cingulata

4. Mexican fruit fly

The correct answer is: Plum curculio

The species classified under the family of weevils is the Plum curculio. Weevils belong to the family Curculionidae, which is characterized by their elongated snouts and distinctive body shapes. The Plum curculio is an important pest of stone fruits, causing significant damage to crops by laying eggs in the fruit and the larvae feeding on the flesh. In contrast, the other species listed do not belong to the weevil family. For instance, the Citrus white fly is associated with the Aleyrodidae family, while Rhagoletis cingulata, known as the apple maggot fly, belongs to the Tephritidae family. The Mexican fruit fly also falls under the Tephritidae family. Understanding these classifications is key to effectively managing pest control in agriculture, highlighting the ecological differences and management strategies required for each group.
