Storage pests
Stored rice can be attacked by a wide range of insects whose identities and cycles differ from those found in the fields. Most feed on rice and any other stored grain. They can be classified into two groups according to the infestation mode: some begin attacking the crops in the field and are brought into the granary or the store with the harvest, as is the case for weevils and moths; others attack only stored grains, and can come from either inside or outside of the store.
