Where is the angoumois grain moth most typically found?

The angoumois grain moth is most commonly associated with whole grain products, particularly in environments such as stored corn. This particular pest has a preference for whole grains because its larvae feed on the grain itself, seeking the nutrients necessary for development. Whole corn, given its storage practices and conditions, creates an appropriate habitat for the angoumois grain moth, allowing it to thrive.

In the context of the other choices, rice storage, wheat silos, and bean crops are not the primary environments for the angoumois grain moth. While these environments may harbor various pests associated with stored products, the angoumois grain moth primarily targets whole grains like corn over these alternatives. Thus, the association with whole corn specifically highlights the typical habitat and feeding behavior of this pest, underscoring its relevance in pest management strategies focused on stored grains.
