Rice weevil

Sitophilus oryzae

The rice weevil looks similar to the grain weevil, but differs from it in its ability to fly and the four indistinctly marked orange dots on its wing covers. Like the grain weevil, it attacks the whole grain, even if it is still in the field, and lays its eggs in the grain. The rice weevil prefers warmer temperatures. Due to the changed storage conditions in production, it can also overwinter in our country, as the temperature never drops significantly without artificial cooling in large bulk quantities. Its breeding and feeding behavior is the same as that of the grain weevil. All types of grain, maize and millet are infested and, like the grain weevil, it can also be found in various food-processing companies as well as storage facilities. Beetle approx. 3 mm long, brown to black with 4 orange spots on the wing covers, able to fly. Damaging effect as with the grain weevil.
