Araecerus fasciculatus
Coffee Bean Weevil
Araecerus fasciculatus, commonly known as the coffee bean weevil, is a polyphagous stored product pest in the family Anthribidae. Adults measure 3–5 mm with a dome-shaped, dark-brown body mottled with light and dark pubescence. The species has been documented on over 100 host plants including coffee, maize, cassava, nutmeg, dried fruits, and various nuts. It completes its life cycle inside seeds and stored products, with development times varying from 29 to 57 days depending on humidity and temperature. Through international trade, it has achieved cosmopolitan distribution in tropical and subtropical regions and is considered economically significant due to damage and contamination of stored commodities.
