Khapra beetle

( Latin: Trogoderma granarium)

Khapra beetles came originally from India. They often congregate in large numbers in the cracks and crevices of walls in warehouses.

Unlike the preceding dermestids this beetle feeds mainly on plant material. It has now spread to almost all tropical and subtropical regions and those areas where it has not appeared have very stringent quarantine regulations to prevent its introduction.

For it is regarded as one of the most serious pests, particularly in grain and food stores.

The khapra beetle is sometimes brought to temperate regions but as it requires a temperature of at least 24° C for breeding there is little risk of it becoming established.
