Guter Bienen-Winter

Die Honigbienen in Österreich haben den heurigen Winter gut überstanden. Das ergibt eine Erhebung von ForscherInnen der Universität Graz. Foto: Pixabay

Die Sterblichkeit der Honigbienenvölker lag heuer bei zwölf Prozent

Der Anteil der Honigbienenvölker, die den Winter nicht überleben, schwankt stark über die Jahre und Regionen. Den Winter 2017/18 haben rund zwölf Prozent der geschätzten 353.000 Bienenvölker in Österreich nicht überlebt. „Die Überwinterung 2017/18 ist für die Bienen recht erfreulich verlaufen, es zeigen sich kaum Gebiete mit hohen Verlusten, die relativ geringe Zahl der verlorenen Völker wurden zum größten Teil bereits wieder nachgeschafft“, erklärt Robert Brodschneider vom Institut für Biologie der Universität Graz. Er erhebt im Rahmen des Projektes Zukunft Biene (Projektleiter Karl Crailsheim) gemeinsam mit ImkerInnen die Sterberate von Bienenvölkern in Österreich und sammelt damit wichtige Daten zum Schutz dieser Insekten. 1391 Imkereien haben dabei Angaben zu insgesamt 28.373 im Herbst 2017 eingewinterten Völkern zur Verfügung gestellt. Im Jahr davor lag die Sterblichkeit bei hohen 23 Prozent. Die Untersuchung wird auch 2019 durchgeführt, um langjährige Trends erkennen zu können.

Cosmetics in the environment: University of Graz proves danger to ants

Titanium dioxide, which is found in cosmetics, for example, is increasingly entering the environment in the form of nanoparticles. This could also put insects at risk. If ants ingest the substance in combination with the pesticide glyphosate, it disturbs the development of their offspring. Scientists at the University of Graz are drawing attention to the negative consequences of this toxic cocktail.
