Achroia

Achroia is a genus of moths belonging to the family Pyralidae, subfamily Galleriinae. These moths are commonly known as wax moths. A notable species within this genus is Achroia grisella, the lesser wax moth.

Achroia species, particularly A. grisella, are economically significant due to their larvae's feeding habits. The larvae consume beeswax, pollen, and the detritus found in beehives, making them pests of beekeeping operations. Their activity can damage or destroy honeycombs, impacting honey production and bee colony health.

Control measures for Achroia infestations in beehives often involve preventative measures such as maintaining strong, healthy colonies, which are better equipped to defend against wax moth infestations. Fumigation with sulfur dioxide or freezing of infested comb are also common methods.
