The invention belongs to the technical field of bee breeding, and particularly relates to a bee
mite parasitism rate detection device which comprises a sealing cover detachably installed at the top end of a
beehive, a plurality of evenly-arranged bee collecting and detecting mechanisms are fixedly connected to the top wall of the sealing cover, a controller is fixedly connected to the top end of the outer portion of the sealing cover, and the bee collecting and detecting mechanisms are electrically connected with the controller; the bee collecting and detecting mechanism comprises a bee collecting box, the bee collecting box is fixedly connected with the top wall of the sealing cover, the bottom end of the bee collecting box is detachably connected with a bee
mite collecting part, a bee inlet mechanism is arranged on one side wall of the bee collecting box, and the outlet end of the bee inlet mechanism is located in the bee collecting box; a cleaning mechanism is arranged on the upper portion in the bee collecting box, and the bee feeding mechanism, the
reagent adding mechanism and the ventilation mechanism are electrically connected with the controller. According to the method, the bee
mite infection rate of the bee colony can be efficiently and accurately detected, and the bee mite infection condition of the whole bee colony can be accurately reflected.
