Mysteries of the hive

The Youtube channel Zeste de science explores all aspects of scientific research, proving that even the most complicated scientific facts can be explained in less than 5 minutes, and that even the most seemingly trivial events of everyday life, if thoroughly studied, can contribute to the biggest technological advances. Episode 17: Whenever a threat appears near a hive, dozens of bees assemble to draw it off. These bees warn each other of the danger by emitting alarm…

They place microphones in sunflower fields... to count bees and other pollinators! Discover the ingenious experiments to study these diverse insects and their effects on our crops, conducted by a team from the Centre for Biological Studies in Chizé.

For over 20 years, honeybees are experiencing excessive mortality. In an attempt to understand the causes, researchers from the laboratory Microorganisms: Genome and Environment (LMGE) in Clermont-Ferrand (France) are studying the role of synergy between a parasite, Nosema, and the use of certain insecticides. For their research, they installed a beekeeping within the university.

This silent 3 minute film takes us into an experimental hive and unveils the birth of worker bees. Using their mandibles to tear off the wax lid from their cells, the bees free themselves from their alveoli. Whitish and hairy, the newborn bees let their hair dry and spread their wings, ready to take up their role as workers within the hive.

Jean-Michel Salles, an economist of the environment at the Montpellier Laboratory for theorical and applied economy (France), is interested in the risks of the pollination decline on the agricultural production. This loss is evaluated in an economical way. The researcher in this film ponders the consequences of this threat on the consumers.

Since 2004, the yellow-legged hornet—also known as Asian hornet—has been spreading throughout Europe at an alarming rate. How can we get rid of this invasive species without killing other insects? The key is in finding the perfect trap...

La série « La science au box-office » s'inspire des codes des bandes annonces hollywoodiennes pour vous faire partager les plus étonnantes études, découvertes et innovations scientifiques de notre époque. Suite à l'apparition dans le ciel d'une variété de frelons colonisant les campagnes et menaçant l'écosystème, une équipe de scientifiques multiplie les initiatives pour repousser l'invasion.

The Asian hornet (Vespa velutina nigrithorax) or yellowlegged hornet is an invasive predatory species which arrived in France from China in 2004. Since then, it has colonized France and all of Europe. Eric Darrouzet, a biologist at IRBI, specialized in this insect, explains its lifestyle and all the problems related to its rapid expansion for the environment, public health and economies. Finally, he talks about his team's work to develop trapping techniques to combat this predator (such as the…

The life of the bee and the organization of the hive's inhabitants around the queen. Physiological changes enable the worker bee to fulfil several different occupational functions in the course of its life.
