Casey, 1924

Prionus cuneatus is a of longhorned beetle in the Cerambycidae, Prioninae. The species was described by Casey in 1924 and is currently considered a synonym of Prionus imbricornis in some taxonomic databases. Like other members of the Prionus, it is a root-boring with subterranean larvae. The species belongs to a genus that has been the focus of recent collecting efforts in the Great Plains using synthetic prionic acid lures.

Taxonomic Status

GBIF lists Prionus cuneatus as a synonym of Prionus imbricornis (Linnaeus, 1767), a well-known eastern North American commonly called the tile-horned prionus.

Pheromone Research Context

in the Prionus, including those related to P. cuneatus/P. imbricornis, have been extensively studied for their use of prionic acid as a female component. This compound has been synthesized for commercial lures used in orchard pest management and ecological research, enabling detection of otherwise rarely encountered species.
