Etymology

Usage Notes
The is sometimes applied loosely to other Trogoderma , but reserve 'Khapra ' for T. granarium, the species of international concern. The synonym 'cabinet beetle' is shared with several other dermestids (e.g., Trogoderma inclusum, T. variabile), so context matters; in regulatory and agricultural settings, 'Khapra beetle' specifically signals the high-risk South Asian origin species. Larvae, not , are the damaging stage and the focus of detection protocols. The species' ability to survive on minute food residues and enter extended makes visual inspection alone unreliable for clearance.
