Two common primary insect pests that attack stored grain are:
1. Rice weevil (Sitophilus oryzae): Rice weevils are small, reddish-brown beetles that infest stored grains, including rice, wheat, barley, and corn. They lay eggs inside the grain kernels, and the larvae feed on the grain, causing damage and reducing its quality. Rice weevils can quickly multiply and infest large quantities of stored grain if not controlled.
2. Indian meal moth (Plodia interpunctella): Indian meal moths are common pests that infest stored grains, flour, cereal, and other food products. The adult moths are small and have distinctive reddish-brown wings with a copper-colored band. The larvae of Indian meal moths feed on the grain, leaving behind webbing and frass (insect excrement), which contaminate the stored grain. They can cause significant damage and lead to mold growth and spoilage of the grain.
