Investigate the death of 20,000 bees

A museum in Canada is investigating the unexpected deaths of 20,000 honey bees living in a special nest, wrapped in a glass layer placed in a gallery at the museum.

" All about 20,000 bees die within 48 hours, " said Amanda Fruci, in charge of public relations at the Ontario Royal Museum in Toronto, on Saturday (February 12, 2011).

" The cause is under investigation, but we know for sure that it is not a disorder of the beehive rupture because it involves bees leaving the nest and never coming back, but in In this case, all died in the nest . "

Under normal conditions, bees lost about 5% of the population. But with a syndrome called rupture disorder (CDD), about 1/3, even 90% or all of the bees will die.

In the US, the government-announced figure last year showed a decline in the number of beehives up to 29% in 2009, the lowest compared to 36 and 32% in 2008 and 2007.

The mystery of the decline in bee numbers has also been reported in Europe, Japan and elsewhere in recent years, threatening crop farming depending on the pollination of honey bees as an agent. intermediate

Thousands of visitors have seen bees working in a specially designed and quite famous glass cage on display at the biodiversity museum of the Royal Ontario Museum for two years.

They were very healthy until last week when they suddenly died in the nest. The museum excluded the possibility that they were hungry or because of the museum staff's fault that caused the deaths of the bees.

Suspecting the cause of the temporary killing of bees is a herd of bees lacking gas, parasites or too few bees working to keep the nest warm in the cold winter.
