PLASTIC HONEYCOMB AND METHOD FOR BREEDING HONEY-BEES OF HIGHER PRODUCTIVITY AND RESISTANCE AS WELL AS QUEEN-BEE CELL OF WHOLE CELL-WALL HEIGHT AND METHOD FOR BREEDING QUEEN-BEES OF INCREASED PRODUCTIVITY

摘要

A plastics comb comprising a center wall and cell walls with normal height at both sides of the center wall is made-up of seveal parts. An injection-moulded center wall and injection moulded cell walls, which are produced separately are connected with each other. The diameter of the cell chamber at the bottom of the cell is larger than that of the cell opening. For breeding queens corresponding combs are provided with a center wall and with cell walls at one side thereof, which are removable from the center wall. The individual cells have cell bottoms, which are entirely or partly exchangeable, for example, as a locking element separate from the cell bottom.
