Pin Test tool - Weimar Needle Punch

Pin Test tool - Weimar Needle Punch

In stock

Product Code: M8300


Beekeeping now and in the future should require minimally invasive interventions in the bee colony to deal with parasites and diseases. Through targeted selection, we can restore the honeybee’s ability to heal itself. This leads to healthier bee colonies, less losses, and higher yields.
The central defence mechanism of a bee colony against brood diseases is the detection, opening and removal of diseased or damaged brood. This removal behaviour is described as positive hygienic behaviour (HYG+). This behaviour should be considered as a key attribute when selecting queens for breeding.
The genetic predisposition to immunocompetence is made visible with the help of the Weimar Needle Stamp. This is done by selectively killing individual pupae and assessing the reaction of the colony.

After testing various colonies with the pinTest stamp for hygienic behaviour, the results show a pre-selection protocol trait in strong colonies for breeding programs.
Breeding for HYG+, as well as for VSH (Varroa Sensitive Hygiene), is based on recessive and quantitative inheritance. By selecting which queens will build up a colony in our hives, we also decide which drones will be available for mating in the next generation. The genetic pool of drones is just as important as the queens’. The drone is haploid, so his cells have 16 chromosomes. Every sperm produced by a drone contains exactly the same genetic material. The queen has 32 chromosomes – 16 from the queens’ eggs and 16 from the drones sperm. (SDI: Single Drone Insemination & MDI: multiple Drone Insemination).

This gives beekeepers the opportunity to build up a bee population that is characterized by pronounced self-healing powers and already allows a certain tolerance for the start of treatments in the first step. Continued selection for HYG+ opens up the possibility of reduced drone cuttings and treatment independent of the calendar. Less treatment = Less costs! Also, a longer retention time of the honey on the colonies, leads to a natural reduction in the water content, this increases both the quality and the quantity yield.

The specially designed tool deliberately damages the brood in order to observe the reaction of the bees.  Designed for 5.4mm cell size - standard worker base cells.  Comes assembled and includes 50 spare surgical needles.
