What is the scientific name for the plum curculio?

Conotrachelus nenuphar
Rhagoletis indifferens
Rhagoletis pomonella
Acrobasis spp.

The correct answer is: Conotrachelus nenuphar

The scientific name for the plum curculio is Conotrachelus nenuphar. This name is significant in the study of entomology and agricultural pest management because it identifies a specific species of weevil that causes damage primarily to stone fruits such as plums, peaches, and cherries. Understanding the scientific name helps in accurately communicating about this pest, which is crucial for effective control measures. Conotrachelus nenuphar is part of the family Curculionidae, which is known for its characteristic snout and destructive feeding habits. By recognizing this specific pest and its impact on fruit crops, agricultural professionals can implement targeted pest management strategies, including monitoring, cultural practices, and chemical treatments that specifically address the threats posed by the plum curculio. The other names listed correspond to different pests that do not affect plum crops in the same way, which is why they are not the correct choice in this instance.
