– [Coyote] So to earn my
white coat, I must eat… – [Guest] One of
these wax worms. – Peep, peep, peep!
Peep, peep, peep! – Peep! Peep! – [Coyote] Like a
robin! I can’t hear you! (safari adventure music) – Whoo! The elevator
almost ate me. It’s been a while since
I’ve been in college. Today, we’re at The
University of Arizona. And we’re going to be getting
up close with some nematodes, but first, we need to find
Dr. Stock, in Room 720. Follow me, guys. – [Mark] So just, walk
into the first open lab you see, is kind
of the play here. – We’re definitely
in the right spot. You got biology and worms
up there on the tack board. Ah! There it is. Room 720. – What’s up guys? – Who let this guy in? – [Mark] I was gonna
say, “Who let Mario in?” – Guys, I am a
trained scientist. – All right here, let’s
see what you’ve been doing. What have you been up to? – Who let you in here
without any permission? – What have you
been up to in here? – You weren’t touching
anything, were you? – No, don’t touch that! – Oh, sorry. – I’m conducting a few
experiments, of my own. Yeah. – We’re looking for Dr.
Stock. Have you seen her? – [Mark] I don’t know.
Maybe, around that corner? – Oh, Dr. Stock!
Paging Dr. Stock. Coyote’s here. – What is all this noise? – There you are! – Nice to meet you. – Nice to meet you, too. You look very official
with the lab coat, and some, I’m assuming, some
important papers of some sort. – Oh, just looking at the
things that I need to pay for, bills of lab equipment
and supplies. – Kind of important, I guess. So, as I understand it,
we’re going to be getting up close with nematodes today. – That’s right and, does
people know what nematodes are? – Yeah, they’re like
a little amphibian. About, about little
warts, real cute, little buggy eyes, right, and
they eep, got that tongue? – [Mark] What? No toads? – Nematodes are roundworms. – Ugh! Roundworms?
Like a parasite? – Like a parasite. Yup. – [Mark] I signed up for toads. – I heard toads, and I
was like, “I love toads.” – Have no fear, because the
ones that you are going to see in my lab are actually
not that gross looking. I actually find them
very cute, interesting. – I’ll be the judge of that. Get my arm up in there.
Oh, now I feel official! How do I look guys? – [Mark] You actually
look more intelligent, believe it or not. – Yes, I have intelligent
things to say. It’s a very astute day
for Coyote Peterson, because we’re going to be
learning about nematodes, which are not amphibians at all, but are actually a parasite. I thought they were just
cute little amphibians. Okay! Let’s get into this. Well, what are we doing today? – Well you are going
to get that actually, bugs get sick too, and one
of the diseases that bugs… – Wait wait wait
wait wait wait wait. Did you say bugs get sick, too? As in insects can get sick? – Yes, so that’s my
profession. I am a bug doctor. – We’ll this is pretty cool. Now, this is one of
the first episodes we’ve ever filmed in
a situation like this, where we’re in a lab. We’re working with microscopes. And I see you’ve
got all these little test beakers and
pipettes out here. So, let’s kind of follow
what it is that you do, and we’re gonna learn
something cool today. – [Mark] Turn it
over to Dr. Stock. Why don’t you tell us about
what we’re looking at here. – Well, yeah. So, as
I mentioned before, I work with insect
diseases with nematodes and the nematodes that
I study are actually very tiny little creatures. So this flask that has
water, and if you can see the flakes that are shaking
inside, those are the nematodes. – Those are nematodes? – Yes. Those are insect
parasitic nematodes. – I see they kind of do look
like little squiggly lines. To me, this just looks
like bad tap water. – Yeah, yeah. And you
shouldn’t drink it actually. – Oh, I was gonna say,
“Can I taste it? Bad idea?” – Well, I wouldn’t
recommend that. – Okay. If the doctor says
don’t drink it, don’t drink it. – I can show you actually
other kinds of nematodes. – Oh, there’s different
kinds of nematodes. Wow! So that…that’s
a nematode. – Yeah, and you know
where it came from? – A poop? – Well, it came from
a lake in Wisconsin, and actually, that’s
a nematode that was parasitizing an immature
stasis of a dragonfly. – Wow, that came
out of a dragonfly? Now how did you extract
it from the dragonfly? – It came out on it’s own. – That’s crazy looking.
Can you actually even see that on your camera? So, that’s nothing for us
as humans to be afraid of, but if you are a
dragonfly larva, that’s like your worst
nightmare. Okay. All right. – [Mark] Well, hey. I noticed
there’s some plants down here. Are you working with
some plant research? – Yes, well actually,
it’s all connected. So, we are studying
nematodes that parasitize insects that are
pests doing more than crops and we… – Okay. Oh! Is that
a big caterpillar? – Yeah. That’s a
big caterpillar. – Wow! – I’ll get it out for you. – [Mark] Oh, wow. It is a big
caterpillar. That’s beautiful. – [Coyote] What kind
of caterpillar is that? It doesn’t bite does it? – No, it’s a Tobacco Hornworm. – So this is a pest
insect, despite that fact that it’s really beautiful. – Yes, they are very voracious. They could feed on
this plant, if we, if I put that caterpillar
on this plant, tomorrow morning,
I have no leaves. – Really? Got it! – Yup. That’s good. So, where does everything start? Right? In my research? – In a tummy? – No. In the soil. – Oh, in the soil!
Doesn’t all life come from the
belly of something? – Actually, I have to say that, thanks to these worms, I’ve
traveled around the world. And I’ve been all over
the world sampling… – What? For worms? – For these nematodes. – Wow! Those worms
are gross looking. What are those? Maggots? – No actually, this
is our guinea pig. And also, I use them
as baits to get the nematodes that are
living in the soil. – That’s nematode bait? – Yeah. So, when I go
to the field and collect dirt samples, I bring
them to the lab, then I put them in
containers like this. I put all these waxworms,
which actually are a pest problem in beehives, because if they get
into the beehives, they will feed on all the
wax in the comb of the hive, and it will destroy the comb. – So that’s where they
get the name, “Waxworm?” – Yeah, yeah. – Makes sense. – So, what I do, I
leave this dirt sitting in another room that
I have in my lab, for a week, and after
that, the magic happens. So, what I get is all these
infected caterpillars. – Those are dead? Woah! Ugh! – [Mark] What happened? – Don’t! Just
don’t! That stinks! – [Mark] Oh! I smell
it! It just hit me! Keep ’em back! I’ve
got a zoom lens. – Oh my gosh! That is putrid! I almost threw up my burrito into your little nematode
waxworm pile there. – In spite of that
smell, actually, there’s no putrefaction
here because actually the nematodes that we study, have inside their
tummies, bacteria, and this is the bacteria that
comes out from the nematodes. – So is that some
valuable research, right there, in that container? – Yes, because
actually, the nematodes, what they do, they
vector the bacteria, who are actually the
true insect killers. So, the bacteria is the
one that kills the insects, – And the bacteria is
coming from the nematode? – Yes. – Okay. So, the nematode
is the distributor of the bacteria that
ends up in the waxworm. – Yes, exactly. – I’m learning here. – And I hope you can
capture this with a camera. So, you have your
dead insects there. – Let me plug my nose and
get down there real close. – [Mark] Oh, yeah.
I see something. – [Coyote] Oh my gosh! That’s
like a deflating wax worm. – [Dr. Stock] Those are
the worms coming out. – [Mark] Why don’t we take
a look under the microscope? Because I think
everyone would really like to see these
worms in action. – Oh, yeah! So, so we can put
these under the microscope, and get an up close look
at these little wigglers. – We can go to my
other lab where we have the microscopes. The microscope! – Dr. Stock, I’m
light-headed here. All those funky smells. Whoo! – So, I have the worms here,
actually ready for you. – So, what’s gonna
happen is, I’m gonna look inside these little eye sockets, and the other camera is
gonna point at the screen, so you guys can see what
it is that I am seeing. Are you ready? – [Mark] Yup. – Here we go. Get that shot
on screen there, Mario. Oh, boy. That is one squiggly worm party! Are you serious? So,
this is what’s going on inside of those waxworms? – Yes, exactly. – And how many of
these are inside a waxworm at any given time? – [Dr. Stock]
Hundreds of thousands. – Hundreds of thousands? – [Mark] Hundreds of thousands? – [Dr. Stock]
Hundreds of thousands. – Wow. That is really cool. Okay, so what I wanna
do now, is I’m gonna crouch down here, and
we’re gonna look at this actually on the screen, so
that I can talk to you guys while we’re looking at this. Now, are we just seeing,
we’re just seeing the silhouettes of them, right? – Yeah, actually, these are
the ones that are coming out from the insects, and we call
them, infected juveniles. – Okay. So these are
opportunistic predators looking for a host, that
they can then infect. They’ll grow inside. And
then, how do they reproduce? Do they reproduce
inside of the waxworms? – So, yes, they will
reproduce in the waxworm or any other insect that
they think is suitable for them, but actually, the nematodes go into
the insect blood, and that sends a signal to the nematodes to
start opening their mouths or anuses, and the
bacteria start coming down. And so, the bacteria
are either defecated, or regurgitated,
and the bacteria throw toxins that kill the
insect, and the insect dies. Now, when the insect
dies, it’s actually the most important
part, because now, there’s all that
food supply for the nematodes to start
growing and multiplying. – Wow! Well, that’s pretty cool. I wish I had a
microscope like this. So, what else can
we take a look at? You have any other worm
species or parasites? – Yeah, I can show you
some human parasites that I use for my class. – Ooh! Human parasites! Let’s check that out. All right, you lead the way! – All right, back
in the dirty lab, and okay, somebody already
placed them on the table. I’m guessing, those are
the human parasites. – [Mark] Whatever gave it away? – Yeah, well I wasn’t
actually even looking at that. I was just looking at
that… This is what I always imagined would
crawl out of my mouth if I had a tapeworm, and I put the
bowl of milk in front of me. Are those tapeworms? – No, actually
these are nematodes. – Those are also nematodes? Giant, super-sized ones! – Yeah, they’re actually is
called Ascaris Lumbricoides. – Whoa, that’s complex
for something that just straight-up can be labeled,
“disgusting,” in my opinion. But you love these
things, don’t you? – Oh, I do. I love this. – This is fascinating to you? How would you know as a human, if you have one of these
inside of your organs? – You probably would have
many of them in your stomach. – No, no, no. Dr.
Stock, there is no way that I have any of
these inside me. – Yeah. And you would
look almost, like, pregnant with a
big swollen belly. – I work on my
physique a little bit. Do you think that I
might have some of those inside of me, though? – Oh, no. I don’t think so. – No. Whoo! In the clear. So, Dr. Stock, there
is a rhyme and a reason behind all the science,
and all the work you’re doing with
these incredibly
fascinating nematodes. Can you sum that up
for us? Real quick. – Yeah. So, actually
early, as I mentioned in the very beginning,
we are trying to develop alternatives
to pest management. – So, how does a nematode then, help you control
the pest population? – Well, nematodes actually are
important insect parasites. If they are mass-produced
and formulated, they can be used
to our advantage. – Okay, so basically
then, the nematodes can help control
populations of pest insects like these caterpillars, that
are just decimating crops. And in a sense,
they’re becoming the pest control of the future. – Exactly. And
actually, even further, they are safe to the
environment and to us. – That is so cool.
Well, this is definitely one of the most complex
and scientific episodes I think we have ever filmed. I learned so much
today about nematodes. Dr. Stock, thank you so much
for having us into the lab. – My pleasure. It’s
been wonderful. – Whew! That was crazy. – [Mark] Come one.
We’re not done yet. – What do you mean,
we’re not done? I was gonna give an outro. – [Mark] You didn’t
have your snack. And you know, the title of this
video, “Eating a Parasite.” – Oh, gosh. I was kinda hoping you guys would
forget about that! – I don’t think you
can leave this lab… – No, no, but I can
say, wait a minute, you can’t leave. I
have a present for you. – What’s the present? – The waxworm. – [Mark] Oh, which
is a parasite. So… – Well, a parasite host. – Hey, if it’s between
eating one of these, or a waxworm, I don’t know man. I think I’d go for the waxworm. – Give me the
waxworm. All right. – I would say so.
Actually, every lab member, to become a lab member,
needs to have one waxworm. – So, to earn my white
coat, I must eat… – One of these waxworms. A great source of protein. – And I’m just gonna
dump this whole thing of waxworms in my
mouth and chew it up? – Oh, no. I can
pick one for you. – Oh, just one? – Just one little snacky. – That’s a lot better. – That’s all I ask,
only one caterpillar. – Oh, you had to pick
the big squisher! – You can become the
official lab member. So, instead of chopsticks,
with these forceps. – Now, how do I know there’s
no nematodes in there? – I can guarantee that. – I’m trusting you here. Wait, I don’t know, guys,
I might puke on this. You know it happens. – Will this help? – Oh, yeah, that’ll do it. That’s 2000 milliliters. That’s probably what
I got in me right now. All right, I’m gonna hand
this little one back to you. – And I can give you that one. – [Mark] Oh! Doctors
have to feed you. – Yeah, yeah. I can help. – [Mark] Like a
little baby bird. – Just to make sure. – [Mark] Can you make a
little squawking sound? Like you’re hungry? – Ugh. Okay. – Peep, peep, peep!
Peep, peep, peep! – Ugh! – Ugh! – [Mark] What’s it taste like? – Ugh, like a bad bean. – [Mark] A bad bean? – Ugh! I’m holding it… – I’ll give you some help. – I swallowed it! – [Mark] You did it? – I swallowed it. – [Mark] You did it. – I swallowed it,
and I didn’t puke. Oh my gosh! You guys wanna try? You wanna join the club? Come on, man. – This might get me to puke. – I don’t think so. – We have the bucket,
we have the worms. – If it didn’t make me puke,
it’s not gonna make you puke. – This is called, “When
the tables have turned.” – Yeah, well look at
me! I’m doing just fine. I ate the big one,
too. Big squisher! – And he’s all energized. – Yeah. Actually, I feel
really good about myself. This is the first
time I’ve never puked from eating something. – I’m impressed. – I’ve puked from eating fruit. These are worms! – That’s definitely
the grossest thing I’ve ever seen you eat. – [Mario] That’s
pretty impressive. – [Coyote] That
one’s not big enough. Get him that big one in
the corner. Ooh, yeah! – What did I do to this guy? – That’s Chunky Charlie! Yeah. All right. Now, make
those bird noises, Mark. – [Mario] Yeah, come on, Mark. – [Coyote] Tweet, tweet!
Come on, little baby bird. – Peep, peep. – Like a robin,
I can’t hear you! No, no, no! No, no. Chew it. – I had to swallow real quick. It made my eyes water. – Did you even chew it? – It popped. It went, “Plew!” – The popping is the worst part. You expect there to be
a real pungent taste, but there isn’t. It actually tastes like a bean. – Okay. Give me my lab coat. – That’s the first time
I’ve ever eaten a bug. – Oh, man. That was… – I wish I could say
that no bugs were injured in the
making of this video, but unfortunately a couple
of them have been eaten. All right, Mario! I don’t think you’re gonna
escape this one, buddy. – I ate a big lunch
and breakfast. – You know you can
always top off a burrito with a little waxworm, buddy. It’s the new dessert. – Where’s your lab coat, Mario? (Dr. Stock laughs) – [Coyote] And, you
know the drill, buddy. You’ve seen us both do it. We’re gonna need some
good bird noises. What bird species
would you like to be? – A cuckoo. – Okay! Let’s hear what a
baby cuckoo sounds like, ’cause it’s dinner time! Mama bird has come back with a fresh pile of waxworms. – I’ll do my little wings? – Yeah, that’s cool. Well, I can’t hear the
sounds. Coo, coo, coo! – Ew! Ew, it popped. – It’s the food of the future. – Well, I’m in the
present right now. And in the present, I
had a burrito, but…nah. You know what? It
wasn’t that bad. It wasn’t that bad. – Somebody get this
man a lab coat! – Oh my gosh. I’m in trouble. Do I have enough lab coats? – Well, I sure hope so. – Well, let’s see. I’ll
give you my lab coat. – Ey! What a good Mama Bird! All right. Good job, guys! – Look at that. – High fives up here. We have all successfully
eaten waxworms. Now, my stomach
feels really funky, so, I’m go ahead
and cut this camera, and place it over here. Wow! I am incredibly
proud of us, guys. We have all eaten waxworms, and we are now all
officially doctors. Dr. Laivins, Dr. Aldecoa. – Wait. We’re doctors? – Yeah. That’s what
the lab coat means. – I don’t think
that’s how it works. – Oh, no. I’m definitely
putting, “Dr. Coyote Peterson,” in front of everything now. Dr. Stock, thank you
so much for having us into the lab today. This was enlightening. I’m Coyote Peterson. Be brave. Stay wild. We’ll see you on
the next location. (whimsical music) Hey, Coyote Pack! I’ve got some great news. We’re doing two live
shows in Australia: one in Melbourne,
and one in Sydney. The tickets are on sale now. And for everyone in
the United States: get excited, because
a West Coast Tour is coming in early 2018. And don’t forget, subscribe, so you can join me and the crew on our next big adventure. I’m Coyote Peterson. Be Brave! (audience cheers)
