Fuente: WIPO "varroa" The bee washing system washes worker bees and filters out varroa mites so that a beekeeper/operator can estimate the number of infected bees in a hive. The system includes a bee containment section with a coarse mesh filter, and a wash material section with a fine mesh filter. The system is structured so that when the bee containment section is loaded with bees, and the wash material section is loaded with wash material, an operator washes the bees by shaking the system. When the wash is complete, the operator detaches the wash material section from the system and counts the mites present on the fine mesh filter.
