The first 21 days of a bee’s life

-
0:14 - 0:19These bees are in my backyard
in Berkeley, California. -
0:19 - 0:21Until last year,
I'd never kept bees before, -
0:21 - 0:25but National Geographic asked me
to photograph a story about them, -
0:25 - 0:28and I decided, to be able
to take compelling images, -
0:28 - 0:30I should start keeping bees myself.
-
0:30 - 0:32And as you may know,
-
0:32 - 0:35bees pollinate one third
of our food crops, -
0:35 - 0:38and lately they've been having
a really hard time. -
0:38 - 0:42So as a photographer, I wanted to explore
what this problem really looks like. -
0:42 - 0:45So I'm going to show you
what I found over the last year. -
0:46 - 0:48This furry little creature
-
0:48 - 0:52is a fresh young bee halfway emerged
from its brood cell, -
0:52 - 0:55and bees right now are dealing
with several different problems, -
0:55 - 1:00including pesticides, diseases,
and habitat loss, -
1:00 - 1:04but the single greatest threat
is a parasitic mite from Asia, -
1:04 - 1:06Varroa destructor.
-
1:06 - 1:09And this pinhead-sized mite
crawls onto young bees -
1:09 - 1:12and sucks their blood.
-
1:12 - 1:14This eventually destroys a hive
-
1:14 - 1:17because it weakens
the immune system of the bees, -
1:17 - 1:20and it makes them more vulnerable
to stress and disease. -
1:22 - 1:24Now, bees are the most sensitive
-
1:24 - 1:27when they're developing
inside their brood cells, -
1:27 - 1:30and I wanted to know
what that process really looks like, -
1:30 - 1:32so I teamed up
with a bee lab at U.C. Davis -
1:32 - 1:35and figured out how to raise bees
in front of a camera. -
1:36 - 1:39I'm going to show you
the first 21 days of a bee's life -
1:39 - 1:42condensed into 60 seconds.
-
1:44 - 1:49This is a bee egg
as it hatches into a larva, -
1:49 - 1:53and those newly hatched larvae
swim around their cells -
1:53 - 1:57feeding on this white goo
that nurse bees secrete for them. -
2:00 - 2:04Then, their head and their legs
slowly differentiate -
2:04 - 2:08as they transform into pupae.
-
2:10 - 2:12Here's that same pupation process,
-
2:12 - 2:15and you can actually see the mites
running around in the cells. -
2:15 - 2:20Then the tissue in their body reorganizes
-
2:20 - 2:24and the pigment slowly
develops in their eyes. -
2:27 - 2:33The last step of the process
is their skin shrivels up -
2:33 - 2:35and they sprout hair.
-
2:35 - 2:39(Music)
-
2:49 - 2:52So -- (Applause)
-
2:55 - 2:58As you can see halfway
through that video, -
2:58 - 3:00the mites were running around
on the baby bees, -
3:00 - 3:04and the way that beekeepers
typically manage these mites -
3:04 - 3:07is they treat their hives with chemicals.
-
3:07 - 3:10In the long run, that's bad news,
-
3:10 - 3:13so researchers are working
on finding alternatives -
3:13 - 3:15to control these mites.
-
3:16 - 3:19This is one of those alternatives.
-
3:19 - 3:23It's an experimental breeding program
at the USDA Bee Lab in Baton Rouge, -
3:23 - 3:27and this queen and her attendant bees
are part of that program. -
3:28 - 3:31Now, the researchers figured out
-
3:31 - 3:35that some of the bees have
a natural ability to fight mites, -
3:35 - 3:39so they set out to breed
a line of mite-resistant bees. -
3:41 - 3:43This is what it takes
to breed bees in a lab. -
3:43 - 3:46The virgin queen is sedated
-
3:46 - 3:51and then artificially inseminated
using this precision instrument. -
3:51 - 3:53Now, this procedure allows the researchers
-
3:53 - 3:58to control exactly
which bees are being crossed, -
3:58 - 4:02but there's a tradeoff
in having this much control. -
4:02 - 4:05They succeeded in breeding
mite-resistant bees, -
4:05 - 4:08but in that process, those bees
started to lose traits -
4:08 - 4:12like their gentleness
and their ability to store honey, -
4:12 - 4:14so to overcome that problem,
-
4:14 - 4:18these researchers are now collaborating
with commercial beekeepers. -
4:18 - 4:23This is Bret Adee opening
one of his 72,000 beehives. -
4:23 - 4:28He and his brother run the largest
beekeeping operation in the world, -
4:28 - 4:33and the USDA is integrating their
mite-resistant bees into his operation -
4:33 - 4:35with the hope that over time,
-
4:35 - 4:39they'll be able to select the bees
that are not only mite-resistant -
4:39 - 4:44but also retain all of these qualities
that make them useful to us. -
4:44 - 4:46And to say it like that
-
4:46 - 4:49makes it sound like we're manipulating
and exploiting bees, -
4:49 - 4:53and the truth is, we've been doing that
for thousands of years. -
4:53 - 4:58We took this wild creature
and put it inside of a box, -
4:58 - 5:00practically domesticating it,
-
5:00 - 5:04and originally that was
so that we could harvest their honey, -
5:04 - 5:07but over time we started losing
our native pollinators, -
5:07 - 5:08our wild pollinators,
-
5:08 - 5:11and there are many places now
where those wild pollinators -
5:11 - 5:15can no longer meet the pollination
demands of our agriculture, -
5:15 - 5:21so these managed bees have become
an integral part of our food system. -
5:21 - 5:23So when people talk about saving bees,
-
5:23 - 5:25my interpretation of that
-
5:25 - 5:29is we need to save
our relationship to bees, -
5:29 - 5:34and in order to design new solutions,
-
5:34 - 5:39we have to understand
the basic biology of bees -
5:39 - 5:45and understand the effects
of stressors that we sometimes cannot see. -
5:46 - 5:49In other words, we have
to understand bees up close. -
5:49 - 5:51Thank you.

- Title:
- The first 21 days of a bee’s life
- Speaker:
- Anand Varma
- Description:
-
We’ve heard that bees are disappearing. But what is making bee colonies so vulnerable? Photographer Anand Varma raised bees in his backyard — in front of a camera — to get an up close view. This project, for National Geographic, gives a lyrical glimpse into a beehive, and reveals one of the biggest threats to its health, a mite that preys on baby bees in their first 21 days of life. With footage set to music from Rob Moose and the Magik*Magik Orchestra, Varma shows the problem ... and what’s being done to solve it. (This talk was part of a session at TED2015 guest-curated by Pop-Up Magazine: popupmagazine.com or @popupmag on Twitter.)
