bumblebee access, must also have a ventilation opening. Hives without a ventilation opening do not allow for air exchange; the accumulation of carbon dioxide in them then shortens the colony's lifespan, just as the increasing humidity in the hive, which has no way to escape, can lead to water condensation. This also occurs when the beekeeper opens the hive, as there is a sudden change in temperature and a shift in the dew point. The condensate can then soak the lining or, in the form of puddles, cling to the bottom. Additionally, an unventilated hive is more susceptible to mould, the walls degrade faster, and the hive loses its properties more quickly. However, any additional opening in the hive presents an easy entry for parasites, including the most dangerous ones such as *Melittobia acasta* and *Aphomia sociella*.<\/li><li>A number of commercial and privately produced hives alike solve these openings by covering them with netting. This should generally consist of at least two (optimally three layers). The outer and inner mesh are intended to withstand damage from bumblebees and larger parasites or predators. Aluminium netting is most commonly used, as a number of plastic nets have been shown to be able to be gnawed through by bumblebees. The most important is the middle mesh, which should form a barrier against the penetration of larval stages of parasites. Many of these, if stopped by the outer netting, are capable of laying eggs there, and the larvae can then overcome the barrier. The purpose of the protective outer netting is therefore only to protect the crucial middle mesh from damage. To prevent this, the outer netting must not touch the middle mesh.<\/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-38f5d96 elementor-widget elementor-widget-text-editor\" data-id=\"38f5d96\" data-element_type=\"widget\" data-e-type=\"widget\" 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<div id=\"attachment_3183\" style=\"width: 762px\" class=\"wp-caption aligncenter\"><img fetchpriority=\"high\" decoding=\"async\" aria-describedby=\"caption-attachment-3183\" class=\"size-full wp-image-3183\" src=\"https:\/\/www.cmelaciplus.cz\/wp-content\/uploads\/2020\/01\/Vetrani_ulku_vakicka_parazitu_nakladena_na_sitku_vetraciho_otvoru.jpg\" alt=\"Bumblebees PLUS - Hive Ventilation - Parasite eggs laid on the ventilation hole netting\" width=\"752\" height=\"642\" srcset=\"https:\/\/www.cmelaciplus.cz\/wp-content\/uploads\/2020\/01\/Vetrani_ulku_vakicka_parazitu_nakladena_na_sitku_vetraciho_otvoru.jpg 752w, https:\/\/www.cmelaciplus.cz\/wp-content\/uploads\/2020\/01\/Vetrani_ulku_vakicka_parazitu_nakladena_na_sitku_vetraciho_otvoru-300x256.jpg 300w\" sizes=\"(max-width: 752px) 100vw, 752px\" \/><p id=\"caption-attachment-3183\" class=\"wp-caption-text\">Ulcer ventilation \u2013 parasite eggs (here from a fly) laid on the mesh of the ventilation opening<br \/>Photo O.Hercog 2018<\/p><\/div>\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-89d7af4 elementor-widget elementor-widget-spacer\" data-id=\"89d7af4\" data-element_type=\"widget\" data-e-type=\"widget\" id=\"2\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f89985d elementor-widget elementor-widget-text-editor\" data-id=\"f89985d\" data-element_type=\"widget\" data-e-type=\"widget\" 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>Mesh material selection<\/strong><\/h4><p>for the network to make sense, it must fulfil three fundamental tasks:<\/p><ol><li>\u00a0To be so <strong>Thick<\/strong>, to stop even the most dangerous parasite, such as Melittobia acasta. Unfortunately, the incidence of this wasp is increasing in breeding facilities.<\/li><li>Despite its density continuing to<strong> ensure adequate ventilation<\/strong> eagle.<\/li><li><strong>Resilience and durability<\/strong> material in the conditions of a ventilation opening. The material's resistance to the movement of larvae or adult parasites that penetrate it, even through external protective mesh.<\/li><\/ol><p>Meeting these three points is not easy at all, and many commercial products don't even come close to the required parameters. The ventilation opening thus remains a gateway for parasites or ceases to fulfil its function. The breeder, especially a beginner, relies on the manufacturer and is then disappointed by the failure of the breeding. Many attempts to solve the netting issue using various household materials also end up the same way \u2013 for example, organza is a frequently used material for this purpose.<\/p><p>The task and work for our group was therefore to find, if possible, material that would best fulfil the required points.<\/p>\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-a4d5eef elementor-widget elementor-widget-spacer\" data-id=\"a4d5eef\" data-element_type=\"widget\" data-e-type=\"widget\" id=\"3\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d67c1b5 elementor-widget elementor-widget-text-editor\" data-id=\"d67c1b5\" data-element_type=\"widget\" data-e-type=\"widget\" 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>Method of testing and selection of materials<\/strong><\/h4><p>The Czech retail market offers the domestic brands Uhelon and Ulester, which are characterised by high-quality workmanship and precision in the manufacture of their screens. These screens therefore meet point 3 \u2013 the requirement for durability and stability. They are made from 100% polyamide (Uhelon) and 100% polyester (Ulester) fibres. There is a vast number of types of these fibres, which differ from one another in terms of mesh size and fibre strength.\u00a0 We therefore selected the commonly used material organza as our reference sample, due to its well-known and practically proven breathability. As the parasitic wasp can pass through organza, we ruled out in advance all nets with a mesh size larger than that of organza.<\/p><p>In addition to the requirement for hole size and their tensile stability, emphasis is also placed on maintaining the breathability of the material so as not to compromise the basic function of the openings \u2013 namely, ventilation and the dissipation of heat and moisture.<\/p><p>Potentially suitable materials were therefore tested for their permeability in a certified laboratory at the Faculty of Textile Engineering, Technical University of Liberec. The following equipment was used for the testing: FX3300 Textext Standard: \u010cSN EN ISO 9237 Pressure gradient: 100 Pa Tested area: 20 cm2.

This is due to the thin fibre structure and its use as a textile rather than a technical sieve. Therefore, dimensions larger than those found cannot be excluded, e.g., if the organza is stretched more to one side.<\/p><p>The size of the female Melittobia acasta, as reported in the literature and confirmed by my own microscopic observations, is approximately 368\u2013340 \u00b5m for the head, 300\u2013316 \u00b5m for the body, and 380\u2013447 \u00b5m for the abdomen. There is some variation due to the size of the individual specimens and their age. Given the diagonal length of the organza (461 \u00b5m) and its not entirely constant width, the possibility of penetration cannot be ruled out when using 100% organza. An online source also mentions the possibility of egg-laying and the larval stage occurring outside the nest itself in the case of Aphomia sociella, which has a larval body width of 300 \u00b5m.<\/p>\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-989609d elementor-widget elementor-widget-image\" data-id=\"989609d\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t<figure class=\"wp-caption\">\n\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"680\" src=\"https:\/\/www.cmelaciplus.cz\/wp-content\/uploads\/2021\/01\/test-prodysnostii-uhelonu-a-ulesteru-1024x680.jpg\" class=\"attachment-large size-large wp-image-11800\" alt=\"\" srcset=\"https:\/\/www.cmelaciplus.cz\/wp-content\/uploads\/2021\/01\/test-prodysnostii-uhelonu-a-ulesteru-1024x680.jpg 1024w, https:\/\/www.cmelaciplus.cz\/wp-content\/uploads\/2021\/01\/test-prodysnostii-uhelonu-a-ulesteru-300x199.jpg 300w, https:\/\/www.cmelaciplus.cz\/wp-content\/uploads\/2021\/01\/test-prodysnostii-uhelonu-a-ulesteru-768x510.jpg 768w, https:\/\/www.cmelaciplus.cz\/wp-content\/uploads\/2021\/01\/test-prodysnostii-uhelonu-a-ulesteru.jpg 1156w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/>\t\t\t\t\t\t\t\t\t\t\t<figcaption class=\"widget-image-caption wp-caption-text\">Breathability test of Uhelon and Ulester compared to organza<\/figcaption>\n\t\t\t\t\t\t\t\t\t\t<\/figure>\n\t\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-b23ea23 elementor-widget elementor-widget-text-editor\" data-id=\"b23ea23\" data-element_type=\"widget\" data-e-type=\"widget\" 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<p>In the presented table, the values are plotted on a colour scale from <span style=\"color: #339966;\">bright green (most meets the required parameter)<\/span> Over <span style=\"color: #ff9900;\">yellow (parameter thresholds)<\/span> do <span style=\"color: #ff0000;\">dark red values (unsuitable for breeding purposes in the given parameter)<\/span>.

In the case of organza, it is an current online offer; where there is a \/x next to the price, it is necessary to verify the minimum order quantity if interested. In the case of orders over 25m, the manufacturer offers a quantity discount.<\/p>\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-ce08eeb elementor-widget elementor-widget-spacer\" data-id=\"ce08eeb\" data-element_type=\"widget\" data-e-type=\"widget\" id=\"5\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c4e963f elementor-widget elementor-widget-text-editor\" data-id=\"c4e963f\" data-element_type=\"widget\" data-e-type=\"widget\" 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>Conclusion and recommendations for material selection:<\/strong><\/h4><ul><li><strong>For trap construction<\/strong>, where <strong>the primary goal is not to vent the ulcer<\/strong> (flap, trapdoor trap) I recommend using material <strong>UHELON 53S.<\/strong> The Uhelon 53S still offers good breathability (65%) compared to Organza, yet its mesh size is approximately 57% smaller. A mesh size with a diagonal measurement of less than 200 \u00b5m should provide a reliable barrier even against the larval stages.<\/li><\/ul><ul><li><strong>For the construction of ventilation openings<\/strong> I recommend using the material <strong>Ulester 32S<\/strong>, the material stands out from the rest thanks to its excellent breathability (98%); the mesh size is already within the safe range, whilst the diagonal size is at the upper limit, yet it still provides a barrier. Given its excellent breathability, it can be used in ventilation systems with two screens, provided that these are not placed directly against one another.<br \/>Unfortunately, according to the manufacturer's statement, the Ulester 32S is not in regular production, only available to order, with a minimum order quantity of 500m at a price of 214 CZK per metre (excluding VAT), which is beyond the usual farming capabilities. A suitable replacement could be the material <b>Uhelon 32S <\/b>whether <b>Uhelon 35S<\/b> sky<b> Uhelon 45S <\/b>a<b> Uhelon 53S<\/b>. However, the choice must be adapted to the specific construction of the hive, given the quality and method of ventilation. I would recommend in these cases already <b>use only one of these technical nets <\/b>in the ventilation system, which should be located where it can be cleaned of dust or water condensate, e.g. by gentle suction or airflow.<\/li><li><strong>The gauze must always be protected from mechanical damage by another net.<\/strong>, which does not limit breathability but acts purely as mechanical protection<\/li><li><strong>The sieve must lie flat against the edges<\/strong> structural solution of the opening.<\/li><li>Structural openings must be designed so that, <strong>to enable status check<\/strong> network integrity.<br \/><br \/>Manufacturer's technical data: <a href=\"https:\/\/www.silkandprogress.cz\/cs\/sita-technicka-data\" target=\"_blank\" rel=\"noopener\">SILK &amp;
