Breeding of book scorpions in winter

Book scorpions ensure a healthy bee colony in a beehive. As a natural symbiont of honey bees and a natural enemy of varroa mites, they are welcome companions in the hive. For the breeding of book scorpions, a large container is required that can be closed tightly against small animals. A layer of small litter and a couple of rough, dry wooden boards or bark trays are laid on the bottom of the container. The collected or purchased book scorpions are then distributed over a large area on the bark shells and boards. The small litter for feeding the breeding animals must be collected from where the book scorpions were found. Otherwise the book scorpions are endangered because foreign animal species can be introduced into the breeding vessel, which can be fatal for the book scorpions and their nymphs.

Book scorpions prefer dry regions around animals with a parasite plague. The book scorpions can be fed by wood lice, mites or fruit flies. The nymphs tend to eat smaller prey such as springtails. In pet food shops, small animals can be ordered for feeding, so that even in winter, when no more prey can be found in the litter, the book scorpions can be fed. A maximum of 30 book scorpions should be kept in a breeding tank. Approximately every 14 days, new small litter, with the microorganisms in it, must be strewn in. When the fertile female scorpions have spun themselves into their brood nests under the wood, they are removed from the breeding tank. The logs with the nests are placed in a new breeding container with small litter. The remaining book scorpions are returned to the original breeding vessel with new wood. The breeding season can last up to four weeks and a female can breed about 5-6 times a year. During the breeding season, the animals do not eat. The female opens the nest after four weeks at the latest and releases her approximately 20-40 offspring.
The dams are then removed from the new breeding vessel by searching the wood for a few days in a row and sweeping the animals back into the original vessel. This procedure is repeated until no more adult book scorpions can be found under the wood of the second breeding vessel. (Caution! Be careful when putting the sticks back! The protonymphs can hardly be seen with the naked eye and can easily be crushed.) The new generation of bred book scorpions must be fed in the same way as in the original container until the nymphs develop into adult offspring.

Breeding book scorpions for a healthy ecosystem in the beehive is worthwhile.
