The varroa mite which has been introduced from Asia damages the bee colony by sucking on the adult bees and the bee nymphs (pupae) until the bee colony is annihilated. The chemical preparations, which are mostly synthetic, which have been available to date are harmful to the bee colony and the bee larvae. No natural enemies of the varroa are known. The present invention proposes a biological control of the varroa using bacteria, bacilli, viruses and fungi, as well as by predatory insects: 1. Selected compost extract in dust form is blown into the bee colony. 2. The same extract is supplied in a curative feed for the bees. 3. The predatory insects are offered a symbiosis with the bee colony. Niches and small spaces (Fig. 1, 2, 3) are provided in the hive where "field rations" typical for them are deposited together with eggs of the particular beneficial species. This biotope must be protected from the cleaning activities of the bees, e.g. by wire gauze (3) and (10). 4. The biotope (Fig. 3) covered by gauze can be automatically replenished throughout the year by waste and flower pollen falling down, which happens in every hive. <IMAGE> |
