Reply to comment by Wagamaga in The lifespans of honey bees living in laboratory environments has dropped about 50% over the last 50 years, hinting at possible causes for the worrisome trends across the beekeeping industry, according to new research by University of Maryland entomologists. by Wagamaga
Sure, it's certainly not neo-nicotinoids..

This happened under lab conditions though.
No chance of outside toxins.

Bees can not fully be raised in lab conditions. pollen sub is not a full replacement for natural pollen, and with the 3-5 mile forage range it is not practical to say we can control their wild food sources.

I know a lady florist that built huge attached greenhouses with bee hive access .. her bees fly in & collect pollen from acanthus to zucchini. That seemed to be successful. The plants & honey sold was used to set up more hives & greenhouses. Delicious honey.

That works to an extent, any time i have seen it attempted seriously ended up with a lot of bees “stuck” inside the top corner of the greenhouse

Of course I didnt go inside so I dont know. But the plants , flowers were magnificent & the Honey tasted great. She took videos of the hives & they were active.

I pray somebody figures it out before its too late.

You can raise them on sugar water though right?

You can raise a human child on sugar water too, at the expense of lifespan.

OK but what are the downsides?

Not really, no. They need a protein source.

Once they are adult they can survive off pure sugar water, but they need high quality protein when they are larvea. Their carbs come from nectar (honey), and their fats and proteins come from pollen. We have artificial pollen substitutes, but it isnt as good as the real stuff.

Then combining hives & greenhouses could be a good thing. It would certainly protect hives from attacks.
redcoat777 t1_iwddaj0 wrote
Yes, though it would be very hard to have enough consistent food supplies for a single hive within one greenhouse, and greenhouses seem to mess up their intenal navigation

I know she was working with NY Botanical Garden & a couple of top notch Universities. There's birds living in a conservatory.

Then i dare say they have reduced the losses to an acceptable level. it generally surprises people how many bees die every day in a healthy colony.

Yes, and it's probably as good for bees nutritionally as a lifetime of fast food would be for us.

And our water sources are increasingly polluted as well.

Forcing bees to live in an entirely unnatural setting couldn't possibly have any negative impact, right?
DonUdo t1_iwc19cn wrote
Apparently it didn't 50 years ago
SweetBrea t1_iwc1mye wrote
You don't think a negative impact can take generations to really start to be observable to us? You don't think generations in a lab without access to the environment that builds an immune system can eventually have large effects on the population as a whole?
DonUdo t1_iwc29ip wrote
Why would you think they breed them exclusively in the lab instead of taking princesses from outside population?
SweetBrea t1_iwc4z03 wrote
Because they literally claim they are "independent of environmental stressors". How could they be sure it isn't environmental if they were just repeatedly harvesting them from, ya know, the environment?
Kangie t1_iwc84qe wrote
> [environmental] Stressors are environmental factors that cause stress. They include biotic factors such as food availability, the presence of predators, infection with pathogenic organisms or interactions with conspecifics, as well as abiotic factors such as temperature, water availability and toxicants.

It's comparing apples to apples.
They aren't comparing lifespan in a lab today with natural 50 years ago.
They are comparing to lifespan in labs 50 years ago.
ohhmichael t1_iwc9dul wrote
And if the lab results 50 years ago and today are 25% affected by environmental conditions, then the results cannot be concluded as being independent of environmental conditions...
Nearatree t1_iwcajs1 wrote
No see, they moved the labs beyond the environment.
SweetBrea t1_iwc5rs7 wrote
I am saying the methods they are using to compare the apples to apples may be what is actually affecting the apples... or bees if you will.

No, that isn't what you said at all.
