Sugarcane rootstock borer weevil

Definition

A vernacular name for Diaprepes abbreviatus, a broad-nosed weevil (family Curculionidae) native to the Caribbean and invasive in the southern United States, whose larvae tunnel into root systems of sugarcane, citrus, and other crops causing significant economic damage.

Etymology

From the crop (sugarcane), the plant structure attacked (rootstock), the larval feeding mode (borer), and the family (weevil).

Example

Larvae of the sugarcane rootstock borer weevil feed on fibrous roots and burrow into the taproot and lower stem of sugarcane, reducing nutrient uptake and providing entry points for root-rot pathogens.

Synonyms

• Diaprepes root weevil
• citrus root weevil
• chichí (Spanish colloquial)

Usage Notes

One of several common names for Diaprepes abbreviatus; specialists typically prefer the scientific name to avoid confusion with other root-feeding weevils. The common name emphasizes its impact on sugarcane, though the species attacks diverse plants including citrus, ornamental plants, and vegetables. Not to be confused with the sugarcane beetle borer (Rhabdoscelus obscurus) or other sugarcane-specific weevils.
