Diaprepes Citrus Root Weevil
The citrus root weevil, Diaprepes abbreviatus, is a large colorful weevil that is native to the Carribbean Islands. This weevil was accidentally introduced into Florida in the 1960's where it has caused extensive damage. It has been intercepted in shipments of plants to California. This weevil will feed on about 270 different plants including citrus, guava, loquat, holly, and other ornamentals.

This pest is a significant threat to both urban and agricultural trees and plants. If you see the adult weevils or plants that they may have damaged, please contact the California Department of Food and Agriculture's Exotic Pest Hotline at 1800- 491-1899.
