Abstract: Breeding comb for solitary bees is comprised of nesting sheets stacked one on top of another and containing grooves forming nesting tunnels (1) of varying sizes, lugs (2) placed over the side edges of the sheet and on the back wall, locks in the form of lugs (4) in the lower part of the base of the nesting sheet forming pass-through channels (5), slide guides (6) placed in the front part of the sheet, interfaces (8) placed on outer sides of the sheets where the individual nesting sheets are separated from each other by a membrane (3), with a shutter (7) placed at the front part of the breeding comb containing inlet holes (9) of varying sizes corresponding to the sizes of the nesting tunnels (1), and holes (10) corresponding to the sizes of the pass-through channels (5).

Abstract: A breeding comb for solitary bees, comprised of single modules in the form of a sheet containing grooves and locks characterised in that, the grooves of the sheet are separated from one another with side walls, while in the lower part the base of the sheet contains lugs that make blocking locks and rabbets in which the side walls of the particular module are inserted, thus forming nesting tunnels with a cross-section with a shape close to a polyhedron, while in the front part the base of the sheet contains a lug and in the rear part the sheet is limited with a rear wall containing a clasp, wherein the external side walls of the sheet are fitted with clasps of the sheet and of the sheet that make side locks, right and left respectively.
