Diaprepes abbreviatus

Definition

A large, flight-capable weevil species in the family Curculionidae, native to the Caribbean and established as a damaging invasive pest in the southeastern United States, California, and elsewhere. Adults feed on foliage of diverse host plants while larvae tunnel in roots, making it a significant pest of citrus, sugarcane, and ornamental plants.

Etymology

New Latin; Diaprepes from Greek diaprepēs 'conspicuous, remarkable', abbreviatus 'shortened', likely referring to body proportions.

Example

Diaprepes abbreviatus larvae feed on citrus roots and are often associated with Phytophthora fungal infections that accelerate tree decline; adult weevils are notable for their ability to survive submersion and disperse via water, facilitating spread between islands and irrigation districts.

Synonyms

• Diaprepes root weevil

Usage Notes

Common names vary by crop and region; 'citrus root weevil' is used in Florida agriculture, while 'sugarcane rootstock borer weevil' reflects its original economic impact in the Caribbean. Not to be confused with other Diaprepes species. The subspecific names D. a. abbreviatus and D. a. distinguendus appear in older literature but are rarely distinguished in applied entomology.
