Das empfohlene Behandlungsschema gegen Varroa erhöht die Überlebensrate der Bienenvölker
Die Einhaltung der empfohlenen Behandlungsschemata gegen Varroa destructor verbessert die Überlebensrate von Honigbienenvölkern während des Winters. Zentrale Ergebnisse: Die Übereinstimmung der Imkerinnen und Imker mit den empfohlenen Maßnahmen zur Bekämpfung der Milbe Varroa destructor wurde überprüft. Der Befallsgrad sowie die Mortalität der Honigbienenvölker wurden gemessen, um den Einfluss der Einhaltung der Empfehlungen zu bewerten. Nichteinhaltung führte zu höheren Milbenbefallsraten und zu erhöhter Völkermortalität. Ein Volk hatte ein bis zu 25-fach erhöhtes Sterberisiko, wenn es nicht gemäß den Empfehlungen behandelt wurde. Die Kommunikation der Auswirkungen von Abweichungen von den Empfehlungen verbessert die Therapietreue. DetailsPractical Guide: 1.6.5 Varroa treatment in mating nuclei

Merkblatt: 2.11 Sackbrut
Die Sackbrut ist eine virale Brutkrankheit der Honigbiene, die vor allem die verdeckelte Brut betrifft. Sie führt typischerweise zum Absterben der Larven, ohne dass ein fauliger Zerfall eintritt. Die folgenden Hinweise basieren auf dem offiziellen Merkblatt 2.11 des Schweizerischen Bienengesundheitsdienstes. Details
