Rice Weevil (Sitophilus oryzae) adults are 3-4 mm in length with a snout. Varies from reddish-brown to nearly black with four light reddish or yellowish spots on its back. It is a major, widespread pest of stored whole cereal grains and cereal products such as pasta. Larval feeding leaves large cavities inside grain and emerging adults leave large emergence holes. Adults feed on the damaged grains and large numbers produce heat and moisture, encouraging mould growth and mites, both of which reduce quality.
