According to some breeders, the bend simulates the shape of a mouse hole, according to others, the main reason is the fact that the nest is not visible and there are no drafts when it is bent.\u00a0<\/p><p><strong>We previously recommended a right angle, but it has been shown that this is not a condition.<\/strong>. If the corridor runs along the bottom of the ulcer, it is quite a logical solution. However, some manufacturers have shortened the corridor and run it from top to bottom \u2013 in such cases <strong>shrews<\/strong> a curvature that serves the same purpose.<\/p><p>An important aspect is also <strong>internal layout of the corridor<\/strong> in the hive. As stated above, 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 it there. A tunnel routed through the centre then practically prevents any possible service intervention during the colony's life. See the careful inspection of the nest with its removal via the bumblebee lift, or the removal of the tube in case of blockage, etc.<\/p><p><strong>End of the pipe in the hive <\/strong>One of the greatest current bumblebee breeders, Jarom\u00edr \u010c\u00ed\u017eek (the bumblebee guru), recommends finishing the pipe in the corner of the hive. Mr. \u010c\u00ed\u017eek discovered through his observations that the queen in a newly settled hive walks along the wall and stops in the corner. Therefore, she will find the pipe outlet there more quickly. This reduces the risk of the queen \u201cfreezing\u201d in the hive (See queen bee settlement in a hive). .<\/p><p>However, here too some breeders use a different solution \u2013 they let the corridor lead out next to the wall and that also works.<\/p><p>We also recommend <strong>Cut the end of the tube at an angle<\/strong>. The entrance then takes the form of an ellipse, and the entrance area is larger, making it easier for bumblebees to find the entrance to the corridor.<\/p><div style=\"width: 496px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.cmelaciplus.cz\/wp-content\/uploads\/2019\/12\/Zariznuti-trubice-1.jpg\" alt=\"Bumblebees PLUS entrance tunnel - detail of the correct termination of the tunnel tube in the bumblebee nest\" width=\"486\" height=\"322\" \/><p class=\"wp-caption-text\">Recommended tube end detail \u2013 corridor<br \/>Trimming and leading to the corner of the hive \u2013 photo O.

However, we consider this solution to be flawed, as bumblebees perceive this space as \u201ea place outside\u201c and happily defecate there, or bring dead bodies or poorly developing larvae to this area. The entire space thus attracts parasites. Due to its great height, it allows parasites to hide easily. For the keeper, this narrow yet tall space is very difficult to access. Cleaning, inspection and repairs are complicated and often cannot even be carried out on the 100%.

Many of us started that way \u2013 a shelter for bumblebees (bumblebee house) with a metre-long pipe, two bends, and the feeling that no queen would settle without it. However, with the passage of time, it became apparent that reality is much more varied, and that the behaviour of individual species differs significantly, with the dependence on the length of the corridor, or its presence, not being so strong.<br \/><strong><br \/>Species that do not require a hallway<\/strong><br \/>Hobbyist breeders agree that many bumblebee species do not require a long tunnel at all:<\/p><ul><li>The tree bumblebee commonly nests in bird boxes without an entrance tunnel. And not only that \u2013 although it prefers nesting in a bird box, it can also nest without problems behind a tunnel longer than 3 metres.<\/li><li>The meadow bumblebee regularly nests in burrows without passageways, but it doesn't mind a passageway.<\/li><li>The field bumblebee often nests in shallow nests in moss and can be hindered by long, broken tunnels \u2013 in some burrows, it literally \u201efreezes\u201c when settling and cannot get out. Nevertheless, it can manage a tunnel if it wants to nest.<\/li><li>The rock bumblebee can easily manage even a short, straight, and unbroken passage, but a long passage is not a problem either. However, with this species, a long passage can sometimes facilitate the creation of unwanted swarms outside the hive (this species is quite known for this \u2013 it also creates swarms within the hive).<\/li><\/ul><p><strong>Species for which a long corridor was previously assumed<\/strong><br \/>It has long been believed that a long, winding corridor is mainly necessary for:<\/p><ul><li>The Buff-tailed bumblebee \u2013 traditionally considered a species that needs a deep underground nest. However, practice has shown that it settles without problems even in shorter, unbroken tunnels. This abundant species makes a \u201eZagorka\u201c when settling. This young lady surprisingly doesn't settle, and only 1 queen out of 6-10 settles easily on average, and the tunnel length doesn't change that.<\/li><li>The Heath Bumblebee \u2013 some collectors even once claimed that it needed a metre or two metre long tube. In the end, it turned out that the length or orientation of the tunnel doesn't play a role. The key is definitely the animal scent in the lining. Once suitable animal hairs are used, the success rate of settlement is suddenly high \u2013 and queens settle even in hives, quite happily even without a tunnel.<\/li><\/ul><p>It is therefore gradually becoming apparent that <strong>Most bumblebee species do not need a long entrance tunnel; absence of a tunnel does not bother some, and for others, a tunnel can even be a hindrance.<\/strong>. Experienced breeders aiming for a specific breed can adapt the corridor strategy according to their intentions.\u00a0<\/p><p>The corridor can serve as a defensive area for the nest against parasite intrusion, for example, bumblebees. However, it is also gradually becoming apparent that bumblebees primarily guard the entrance opening and do not post sentries in the corridor. For instance, if a bumblebee penetrates the entrance opening into the hive, the chances of workers stopping it are small, albeit supported by observation.\u00a0\u00a0<\/p><p>Some breeders place bumblebees in hives without a tunnel, or remove the tunnel over time \u2013 if it becomes clogged.<\/p><p>However, manufacturers cannot afford to produce a mould for each individual type. Therefore, they opt for short, simple, and slightly unbent corridors that:<\/p><ul><li>enable the successful settlement of all common species,<\/li><li>it harms no one,<\/li><li>they simplify construction and maintenance.<\/li><\/ul><p><strong>What is still important to us, however, is the brightness of the corridor.<\/strong><\/p><ul><li>Manufacturers often use tubes with an outer diameter of 20\u201325 mm. With such narrow tubes, it has already happened several times that the passage became blocked \u2013 for example, when a young, sick mother died in it, or the bumblebees blocked it with bedding and debris. The bedding is often transported out of the passage as the nest grows.<\/li><\/ul><p><strong>When a long corridor can help, or is necessary<\/strong><\/p><ul><li>The corridor therefore primarily serves as a structural element today \u2013 a passage through the hive wall (essential in a double-walled hive), secure fastening of the flap, and routing of the flight hole to a suitable location.<\/li><li>If a hive has an entrance reducer, a longer corridor can partially prevent the larvae of *Aphomia sociella* (greater wax moth) from entering the nest. This does not offer 100% protection, but it can help in some cases.<\/li><\/ul><p><strong>Summary<\/strong><\/p><ul><li>The corridor in a bumblebee nest is a good example of how bumblebee husbandry in nests is constantly moving forward. More breeders are sharing their experiences and observations, and this leads to changes. You can offer improvements through us.<\/li><li>There are various approaches, and over time, a breeder will find their proven method, which they will swear by. However, this does not mean that other paths and possibilities do not exist.\u00a0<\/li><li>On our pages, we share solutions that have been tested and proven in practice. Therefore, we wait for such solutions to be confirmed. That's why you'll find more options, and you can choose from them.<\/li><li>Likewise, you can offer your proven solutions to others through us and thereby advance bumblebee husbandry.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-670b65b elementor-widget elementor-widget-text-editor\" data-id=\"670b65b\" data-element_type=\"widget\" data-e-type=\"widget\" id=\"7\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h4><strong>Supplement<\/strong><\/h4><p>Also look at possible solutions for ulcer placement.
