Braulidae
Braulidae, commonly known as the bee louse, is a family of tiny, wingless dipteran insects. Despite being referred to as lice, they are actually specialized flies that have evolved to live as ectoparasites on the bodies of adult honey bees. They are found globally in regions where apiculture is practiced.

Braulidae
The primary host for Braulidae is the European honey bee (Apis mellifera). These parasites attach themselves to the bee's thorax, preferring the queen bee due to her larger size and longevity. By irritating the bee's mouthparts, the parasite forces the host to regurgitate food, which the louse then consumes directly from the bee.
The life cycle of the bee louse is intricately linked to the hive environment. Female adults lay eggs on the inner surface of honeycomb wax cappings. Upon hatching, the larvae burrow through the wax, creating tunnels that damage the structural integrity of the cappings. They pupate within these wax galleries before emerging as adults to infest new hosts.
The economic impact of Braulidae infestation is significant for beekeepers. While they do not directly kill the bees, high levels of infestation cause severe stress, particularly to the queen. This stress leads to reduced egg-laying capacity, decreased brood rearing, and lower overall colony vitality, which can eventually lead to colony decline.
Effective management strategies for controlling Braulidae focus on hygiene and direct treatment:
- Regular inspection of queen bees for signs of infestation.
- Treatment of colonies with approved chemical strips or sublimation methods.
- Frequent replacement of old or damaged honeycomb cappings.
- Maintaining strong colony health to naturally suppress parasite population growth.
