 IN-2.0 Rice Weevil

Sitophilus oryzae (LINNÉ)


Similar in appearance to the granary weevil but is smaller (2.3-3.5 mm long) and has reddish spots on the brown wing covers.


A dangerous stored grain pest in warmer climates; it infests all types of grain and is often found together with granary weevils.


The larvae can also develop in farinaceous products, buckwheat, peas, acorns, chestnuts, and cottonseed; the weevil also feeds on flour, hemp-seed, biscuits, waffles, white bread, and tobacco.
