Bees are disappearing by the millions in America and Europe.
< p class="e-p">They are small, but essential to our food and ecosystems. For several years, they have been disappearing by the millions. As May 20 marks World Bee Day, learn about these complex pollinating insects that even inspire philosophical wisdom in theatre.
Did you know that the honeybee, or honey bee, honey, has one of the most elaborate communication systems in the animal world? Indeed, this forager secretes odorous substances that allow it to transmit information to other members of its colony.
The host Charles Tisseyre is interested in this subject on the program Découverte of September 18, 1994.
« Some means of bee communication are so complex that scientists agree that these insects have developed a real language.

Report by animator Charles Tisseyre and director Jeannita Richard on the communication system of bees.
It is the Austrian zoologist Karl von Frisch who decodes the dance language of bees. As early as 1919, he built a hive where he could observe the movement of these creatures. After several years, he realizes that their swarming is in fact an organized code to transmit messages. A form of dance.
Why do bees communicate in such complex ways? It would be a question of survival. An elaborate communication system allows them, for example, to know the best source of nectar. A great way to collect food efficiently!
According to the French philosopher Michel Onfray, bees teach us the same lesson that Nietzsche taught. “We are not free, we never have a choice. We are the product of necessity. »
In 2012, Usine C, in Montreal, staged the text of Michel Onfray in the play The Wisdom of Bees. Journalist Tanya Lapointe goes to the scene for the Téléjournal Grand Montréal 18 h of September 12, 2012.
Report by journalist Tanya Lapointe on the play La Sagesse des abeilles by Michel Onfray presented at Usine C, in Montreal.
Director Jean Lambert-Wild has chosen to use real insects to illustrate the author's words. The bees, which come from Saint-Marc-sur-Richelieu, are housed on the roof of Usine C. From their hive, they pass through a pipe to give life to a luminous statue, on stage.
An existential exploration that requires, according to the journalist, a certain intellectual effort.
“Across America and Europe, bees are disappearing by the millions. »

This is what host Charles Tisseyre explains on the show Découvertefrom September 14, 2008. Scientists call this phenomenon, which appeared in 2006, “bee colony collapse syndrome”.
Report narrated by host Charles Tisseyre on the decline of bees in America and Europe. Directed by: Jean-Pierre Rogel and Marièle Choquette.
What are the causes of the rapid death of forager bees? Entomologists accuse varroa, a parasitic mite that feeds on the blood of bees. But as Charles Tisseyre says, varroa does not kill them.
Scientists believe they have found the culprits. The IIV virus and the fungus Nosema ceranae attack the gut of bees. When they act together, they can cause its death.
The decline of these insects continues to worry beekeepers while significant losses are recorded in North America. Our agricultural practices could explain this disappearance. The use of pesticides, such as neonicotinoids, and monoculture are pointed out.
The phenomenon is particularly worrying since a large part of the fruits, vegetables and other plants that we we consume depend on the pollination of bees.
