Trogoderma granarium, commonly known as the Khapra beetle, is a small, reddish-brown beetle known for its destructive feeding habits on stored grains and seeds. It thrives in warm, dry environments and is notably resilient, capable of surviving in harsh conditions without food for long periods.

The Trogoderma granarium, commonly known as the Khapra beetle, is native to the Indian subcontinent. This region encompasses countries such as India, Pakistan, Bangladesh, and parts of Sri Lanka.

The Khapra beetle thrives in warm, dry climates typical of its native region. It is often found in areas with low humidity and high temperatures, which facilitate its development and reproduction.

Trogoderma granarium is primarily a storage pest, infesting a wide variety of stored products, including grains, seeds, and dried animal products. It is well-adapted to survive in stored environments, where it can remain dormant for extended periods during unfavorable conditions, making it a notorious pest in grain storage facilities.
