All bee species threatened by pesticides

Bees are going extinct…but not the ones you think

22 May 2018

You’ve probably heard for years that bees are in dire straits. Which is true…but it’s probably not the bees you’re thinking of. We talk to a bee researcher about what’s really at stake for bees, global agriculture, and all the almonds you’ve ever eaten.

Red mason bee-bumblebee queen conflict

This 20 April 2018 video shows a conflict at a daffodil flower between a male red mason bee and a large earth bumblebee queen.

Joost Borsboom in the Netherlands made this video.

Researchers found that environmental threats are piling onto the stress faced by nest-building bumblebee queens: here.

Dutch national bee count, Top Ten, update

This 22 April 2018 video is about the Dutch national bee count in Drenthe police.

After the provisional results of the first ever Dutch national bee count of 21/22 April 2018, now definite Top Ten results (translated; over 40,000 bees counted):

Honey bee – 14,378
Red mason bee – 6,167
Large earth bumblebee – 2,840
Andrena carantonica -2,514
Tawny mining bee – 1,989
Common carder bee -1,941
Sachem bee – 1,882
Tree bumblebee – 1,882
Garden bumblebee – 1,860
Eristalis hoverfly [not a bee] -1,827

National bee count in the Netherlands

This 20 April 2018 Dutch video is about the first ever national bee count.

On 21 and 22 April 2018 was the first ever national bee count in the Netherlands. 3400 people counted almost 35,000 bees of various species.

The most counted species was the honey bee: almost 12,000 individuals. Second was the red mason bee, counted over 5,000 times. That wild bee species often lives in insect hotels. That it was counted so much is a sign that insect hotels work,

Ariana Grande song commemorates Manchester victims

This 19 April 2018 music video is Ariana Grande – No Tears Left To Cry.

The lyrics of the song are here.

In the song, Ms Grande commemorates the victims of the bloody attack on her 22 May 2017 concert in Manchester, England.

That crime was perpetrated by Salman Abedi, sent to the 2011 Libya war, with the connivance of the British secret police, to fight as a child soldier in NATO’s regime change bloodbath. That war drove Abedi completely horribly mad.

In Ms Grande’s video clip, a honey bee features. Honey bees are symbols of the city of Manchester.

More wild bees good for humans

This video from the USA says about itself:

25 August 2015

Everyone knows honey bees, but the world is full of different kinds of bee species that are important for pollinating many plants. Dr. Margarita Lopez-Uribe, a specialist on bees, shows how important and diverse bees are in this older Naturalist Outreach STEM video.

This video was produced by Drs. Linda Rayor, Margarita Lopez-Uribe, and Cornell University’s Naturalist Outreach Program. The videos were funded by Cornell Cooperative Extension and New York State 4-H. Look into both programs for more good STEM materials and videos.

The more kinds of bees, the better for humans

Study of 48 farms in two states shows abundance of species means lots of pollination

February 15, 2018

The larger an area, the more species of wild bees are needed to pollinate crops, a Rutgers University study shows.

The findings appear today in the journal Science.

Many controlled ecological experiments have shown increased pollination results from having more species, but the Rutgers-led study is one of the first to confirm that increase in nature. The researchers observed, collected and identified more than 100 species of wild bees pollinating crop flowers on 48 farms in New Jersey and Pennsylvania over several years. More than half (55) of these species were needed for pollination at one or more farms in one or more years.

Pollination is an “ecosystem service” — one of the life-sustaining benefits, like clean air and water, we receive from nature.

“Our results confirm the importance of biodiversity in keeping the planet habitable for human beings, at least if our findings apply to other ecosystem functions as well”, said lead author Rachael Winfree, a Rutgers University-New Brunswick ecologist.

Scientists estimate that wild pollinators provide as much as half the crop pollination that occurs worldwide. At a time when domestic honeybees in North America are beset with colony collapse and other problems, the role of wild pollinators becomes even more important.

“I like to think of this as a real-world question,” Winfree said. “These are real farms and real farmers, and each farmer needs his crops pollinated. The answer turns out to be, that when you require that all farms are pollinated, you need an order of magnitude more bee species than has been needed in experiments.”

In her earlier work, Winfree made several suggestions for farmers and landowners who wanted to encourage wild pollinators to pollinate their crops.

“Farmers can plant fallow fields and road edges with flowering plants, preferably plants whose flowering periods are different, because wild pollinators need to be supported throughout the growing season,” Winfree said. “They can reduce pesticide use and avoid spraying during crop bloom when more bees are in the crop field.”

The study also included researchers from Rutgers, Consejo Superior de Investigaciones Cientificas in Spain, the University of Minnesota, the University of California-Davis, and the University of Manitoba.
