A typical example of such a species is the buff-tailed bumblebee (Bombus terrestris). .\u00a0<\/p><p>Some species nest in haystacks, for example the Common carder bee\n(Bombus pascuorum), they don't need any corridors, but on the other hand, they don't mind them.\u00a0<\/p><p><i><em>You can read more about the nesting methods of individual bumblebee species <\/em> <p><\/p>\u00a0<\/i><\/p><p>From observations and experience, it can be seen that an entrance tunnel is needed where the mother - the queen of a species that nests in the ground - genuinely requires such a tunnel and feels content and safe there. She instinctively expects it and seeks such a nesting place. Nests without tunnels therefore have a lower success rate of settlement with these queens.\u00a0<\/p><p>However, a corridor doesn't have to be present in the nest constantly. Once the nest is strong or when we move a strong nest (not a small nest with the first generation of workers, e.g. from breeding stock from Troubsko), the corridor is no longer so essential. It can even happen that the corridor becomes clogged with dirt during nest activity, which then causes problems.\u00a0<\/p><p><span style=\"font-weight: normal !msorm;\"><strong>The entrance hall is therefore crucial at the beginning of the nest's development<\/strong><\/span>, then it can be removed if necessary.\u00a0<\/p><p><em> You can read about how to remove the entrance corridor \u201cwhilst the building is in use\u201c <p><\/p><\/em><\/p><p>The corridor also has for bumblebees\u00a0<strong>defensive meaning.<\/strong>\u00a0 If a stronger intruder (a bumblebee queen, a strong queen of another species, etc.) tries to penetrate the nest, the workers can use their numerical superiority to stop the intruder in the corridor. They will not succeed in the open space of the nest, but they have a chance in the corridor.<\/p><p>Breeders know that bumblebees build from a certain stage of nest development\u00a0<strong>patrols to the air intake<\/strong>.

When they meet and cannot fit, they have to turn back. They also lose pollen baskets here, which they can no longer use. This costs them a lot of energy and leads to unnatural delays in operation (traffic jams). <br \/>In nests in the wild, bumblebees can modify the tunnel (a tunnel in a rodent burrow).

This results in a length of approx. 50-60 cm for a 30x30x30 cm ullage. Therefore, one right angle is recommended.<\/p><p>The reasons for it are not unified. According to some breeders, the bend simulates the shape of a mouse's burrow. According to other breeders, the main reason is that when the nest is bent, it's not visible into the nest and drafts, to which the mother is very sensitive in the initial phase, are limited.\u00a0\u00a0<\/p><p>An important aspect is also <b>Internal layout<\/b> \u2013 the tube should be routed along the sides of the hive, not through the centre. The central space of the hive should be used for the nest and the bumblebees will generally start building there. <br \/>The centrally guided corridor then practically prevents any service intervention during the colony's lifetime and inspection of the nest by removing it via the , or removal of the tube in case of blockage, etc.<\/p><h4><b>The end of the pipe in the hive<\/b><\/h4><p>One of the leading bumblebee keepers today, Jarom\u00edr \u010c\u00ed\u017eek (the bumblebee guru), recommends positioning the tube\u2019s outlet in the corner of the hive. Through his observations, Mr \u010c\u00ed\u017eek has found that in a newly colonised hive, the queen travels along the wall and stops in the corner.

Smaller diameters risk blocking the tunnel, which the workers will not be able to clear. Solving this problem is then much more difficult than in the case of internal tunnels. <br \/>The protective factor of a smaller diameter (the chance of a worker bee meeting a parasite in the corridor) is replaced here by the length of the corridor.

We recommend a fixed passage through the hive using a small section of pipe, where only the part necessary to connect the opposite part of the outer corridor extends outside the hive (male-female system). We recommend a similar adjustment for the slide. The outer corridor is then fitted from both ends onto these short pipes. This method allows for easy cleaning of the corridor, hive, and slide.

From a short piece of HT pipe, we will make a female connector for the corridor. This should ideally be fixed either by gluing (with hot glue) into a pre-prepared notch. Another option is to use an offset wooden block, into which a part of the pipe is firmly seated, and the block is firmly attached to the rear of the flap (as if it were a side wall of the hive). Be careful not to change the internal passage of the corridor in the flap, which must be maintained even when intervening directly in the flap body. We recommend this pipe connector section on the flap to be only as long as it can be safely connected to the long corridor using a male-female system. The reason for this is the maintenance of the corridor flap. <br \/><em><strong>Recommendation<\/strong>\u00a0 It is advantageous for the flapper valve to be on the male side and the long corridor on the female side, as this allows the long corridor to be sealed off with a blanking plate at night if necessary, the flapper valve disconnected, and necessary servicing carried out without disturbing the bumblebees or risking parasite infestation during the servicing period.<\/em><div id=\"attachment_2557\" style=\"width: 310px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-2557\" class=\"size-medium wp-image-2557\" src=\"https:\/\/www.cmelaciplus.cz\/wp-content\/uploads\/2019\/12\/\u010dmel\u00e1ci-PLUS-dva-zp\u016fsoby-napojen\u00ed-klapky-na-vn\u011bj\u0161\u00ed-chodbu--300x195.jpg\" alt=\"Bumblebees PLUS two ways to connect the flap to the external passage\" width=\"300\" height=\"195\" srcset=\"https:\/\/www.cmelaciplus.cz\/wp-content\/uploads\/2019\/12\/\u010dmel\u00e1ci-PLUS-dva-zp\u016fsoby-napojen\u00ed-klapky-na-vn\u011bj\u0161\u00ed-chodbu--300x195.jpg 300w, https:\/\/www.cmelaciplus.cz\/wp-content\/uploads\/2019\/12\/\u010dmel\u00e1ci-PLUS-dva-zp\u016fsoby-napojen\u00ed-klapky-na-vn\u011bj\u0161\u00ed-chodbu-.jpg 600w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><p id=\"caption-attachment-2557\" class=\"wp-caption-text\">Two ways to connect a flap to an external corridor.<br \/>Left by gluing into the pre-milled groove.<br \/>On the right, it\u2019s easier to create an attachment that connects to the rear side panel of the flap from behind.\u00a0<br \/>Photo K.
