Fecha de publicación: 27/09/2007 Fuente: WIPO "beekeeper" An apparatus and method for observing, trapping, reducing and controlling mites which infect and kill honey bees in a beehive. A screen, preferably permanently installed in the bottom board, separates mites from the bees, and sub-board below the screen traps the mites to prevent re-infestation or allows detection and observation. Large air space between the sub-board and screen and the use of a sticky substance on the sub-board prevent bees from climbing up into the beehive and prevent re-attachment and facilitates monitoring and the use of inert powder such as powder sugar. The sub-board is accessible from the rear of the beehive so that the entry and exit of the bees into and out of the beehive are not disturbed and also from the front when rear access is not available allowing this board to have a double use.
