These bees are in my backyard
in Berkeley, California.
-
Until last year,
I'd never kept bees before,
-
but National Geographic asked me
to photograph a story about them,
-
and I decided to be able
to take compelling images,
-
I should start keeping bees myself.
-
And as you may know,
-
bees pollinate one third
of our food crops,
-
and lately they've been having
a really hard time.
-
So as a photographer, I wanted to explore
what this problem really looks like.
-
So I'm going to show you
What I found over the last year.
-
This furry little creature
-
is a fresh young bee halfway emerged
from its brood cell,
-
and bees right now are dealing
with several different problems,
-
including pesticides, diseases,
and habitat loss,
-
but the single greatest threat
is a parasitic mite from Asia,
-
Varroa destructor.
-
And this pinhead-sized mite
crawls onto young bees
-
and sucks their blood.
-
This eventually destroys the hive
-
because it weakens
the immune system of the bees,
-
and it makes them more vulnerable
to stress and disease.
-
Now, bees are the most sensitive
-
when they're developing
inside their brood cells,
-
and I wanted to know
what that process really looks like,
-
so I teamed up with a bee lab at UC Davis
-
and figured out how to raise bees
in front of a camera.
-
I'm going to show you
the first 21 days of a bee's life
-
condensed into 60 seconds.
-
This is a bee egg
as it hatches into a larva,
-
and those newly hatched larva
swim around their cells
-
feeding on this white goo
that nurse bees secrete for them.
-
Then, their head and their legs
slowly differentiate
-
as they transform into pupae.
-
Here's that same pupation process,
-
and you can actually see the mites
running around in the cells.
-
Then the tissue in their body reorganizes
-
and the pigment slowly
develops in their eyes.
-
The last step of the process
is their skin shrivels up
-
and they sprout hair.
-
(Music)
-
So -- (Applause)
-
So as you can see
halfway through that video,
-
the mites were running around
on the baby bees,
-
and the way that beekeepers
typically manage these mites
-
is they treat their hives with chemicals.
-
In the long run, that's bad news,
-
so researchers are working
on finding alternatives
-
to control these mites.
-
This is one of those alternatives.
-
It's an experimental breeding program
at the USDA Bee Lab in Baton Rouge,
-
and this queen and her attendant bees
are part of that program.
-
Now, the researchers figured out
-
that some of the bees have
a natural ability to fight mites,
-
so they set out to breed
a line of mite-resistant bees.
-
This is what it takes
to breed bees in a lab.
-
The virgin queen is sedated
-
and then artificially inseminated
using this precision instrument.
-
Now, this procedure allows the researchers
-
to control exactly
which bees are being crossed,
-
but there's a tradeoff
in having this much control.
-
They succeeded in breeding
mite-resistant bees,
-
but in that process, those bees
started to lose traits
-
like their gentleness
-
and their ability to store honey,
-
so to overcome that problem,
-
these researchers are now collaborating
with commercial beekeepers.
-
This is Bret Adee opening
one of his 72,000 bee hives.
-
He and his brother run the largest
beekeeping operation in the world,
-
and the USDA is integrating
-
their mite-resistant bees
-
into his operation
-
with the hope that over time,
they'll be able to select
-
the bees that are not only mite-resistant
-
but also retain all of these qualities
-
that make them useful to us.
-
And to say it like that
-
makes it sound like we're manipulating
and exploiting bees,
-
and the truth is, we've been doing that
for thousands of years.
-
We took this wild creature
-
and put it inside of a box,
-
practically domesticating it,
-
and originally that was
so that we could harvest their honey,
-
but over time we started losing
our native pollinators,
-
our wild pollinators,
-
and there are many places now
where those wild pollinators
-
can no longer meet the pollination
demands of our agriculture,
-
so these managed bees have become
an integral part of our food system.
-
So when people talk about saving bees,
-
my interpretation of that
-
is we need to save
our relationship to bees,
-
and in order to design new solutions,
-
we have to understand
the basic biology bees
-
and understand the effects
-
of stressors that we sometimes cannot see.
-
In other words, we have
to understand bees up close.
-
Thank you.
