Cockroach Derby: who is the fastest roach in the west?


The highlight of today’s clambake is the cockroach race cockroach derby. A roach race is quite an interesting event. It helps draw attention to our educational events. Most people perceive cockroaches as an intruder. They don’t see them as a natural pet. These’s Madagascar roaches are housed as pets from a lot of companies. Their normal diet is like dog food or cat food. But the day and races, and a couple days before they’ll give
him bananas, to get them all hyped up and ready to go. You tell the roaches if they don’t behave,
they’re not getting their bananas for dinner. These specific cockroaches are roughly three inches long. They’re hissing cockroaches from Madagascar. We have 4 roaches on a track. We name them after a variety of people, it could be
our attendees, it could be presidents, it could be governors. Some just incredible things can happen with these roaches. We train the roaches very, very delicately. You know, we we provide them a very, very nice home environment. We provide them moisture. We provide the bananas. We feed them very well. We give them the very, very careful time. So when they’re ready to race, they’re ready to go. Roaches are kept drug free and alcohol free. It is very, very important to the American quality of life. A cockroach races very unpredictable. A cockroach does not do things the way a
normal horse race or a dog race would go. You think that they’re going to go right to the end and go straight. And they just turn around. It just brings a lot of unexpected joy to see race with cockroaches. It’s going to be a close race. It is. By a nose. My Roach won. My first winning at the roach race. I guess it’s a good feeling. When I tell people I’m a professional roach handler , they sometimes look
at me with envy, and other times they look at me with disgust. It’s just a side bar for everybody to have a little fun. My name is Jerry Smith here at the Roach Races. You’re watching Over The Edge. Hi, I’m Phil Cooper here at the Roach races. And you’re watching Over The Edge.

(CRAIG) ALL RIGHT AND NOW WOULD LIKE TO WELCOME TIM FROM THE ROCHESTER MUSEUM AND SCIENCE CENTER TO THE
SHOW HEY TIM. (TIM) HI GUYS. (DONNA) HI TIM. (TIM) GOOD TO SEE YOU AGAIN.(DONNA) BEFORE YOU TOUCH THOSE THINGS. (TIM) YEAH I WASHED MY HANDS. (CRAIG) SO YOU GOT HISSING COCKROACHES. WHERE ARE THOSE THINGS FOUND? BESIDES ON THAT LOG. (TIM) MADAGASCAR. (CRAIG) ALRIGHT. (TIM) THAT’S WHY THEY’RE CALLED MADAGASCAR HISSING COCKROACHES AND THAT IS ON
THE EASTERN OFF THE EASTERN COAST OF AFRICA. SO THEY’RE PRETTY
NEAT AND THEY’RE. (DONNA) OH I HEARD THAT. (CRAIG) YUPP YOU CAN HEAR IT. (DONNA) THAT’S WEIRD. (TIM) HISSING. THEY ACTUALLY HISS BY PUSHING AIR THROUGH THE SEGMENTS IN THEIR ABDOMEN. WHERE THEY
BREATH THROUGH. SO THEY’RE THE ONLY INSECTS THAT REALLY
DO THAT. YOU GET OTHER INSECTS THAT MAKE NOISE USUALLY THROUGH
SOMETHING LIKE STRANGULATION OR RUBBING BODY PARTS GATHER. HE DOES IT AND HE’S GOT THREE DIFFERENT ONES. THAT ONE WAS
BECAUSE HE WAS STARTLED. THEN HE’S GOT ONE FOR MATING. TRYING TO ENTICE THE FEMALES AND THEN ONE FOR FIGHTING. WHEN HE’S GOING UP AGAINST ANOTHER MALE FOR
DOMINANCE. (DONNA) NOW HE’S PRETTY BIG. HOW LARGE WILL THEY GROW AND
HOW LONG IS A TYPICAL LIFESPAN? (TIM) ACTUALLY HE’S SMALL COMPARED TO THE FEMALE. IF WE TAKE A LOOK AT
THE FEMALE HE’S ABOUT, HE’S JUST UNDER THREE INCHES. THE FEMALE
WILL GROW TO ABOUT THREE INCHES LONG. THE MALE BE TWO TO THREE
INCHES AND YOU CAN TELL THE DIFFERENCE BECAUSE THE FEMALE THE CROWN DOESN’T HAVE ANY HORNS
AND THE MALE DOES. (DONNA) OKAY YEAH I SEE THAT. (CRAIG) SO WHAT DOES THEIR DIET
CONSIST OF? WHAT ARE THESE GUYS GONNA EAT? (TIM) THESE GUYS EAT JUST ABOUT
ANYTHING. THEY LIKE THINGS, THESE GUYS EAT DOG FOOD. FOR THE PROTEIN BUT THEY CAN
LIVE ON VEGETATION JUST LIKE ANY OTHER INSECT ROACH THAT GOES AROUND. THEY’LL CHEW ON ANYTHING THAT’S ON THE GROUND. SOMETIMES
EVERY NOW AND AGAIN A LITTLE CEREAL OAT CEREAL THEY’RE LIKE YOU
KNOW JUST CHANGE PACE. SO THEY ENJOY THAT AND THEY DO PRETTY WELL WITH IT. (DONNA) ALL RIGHT NOW YOU TALKED ABOUT THE HORNS BUT ARE THESE THINGS
STICKING OUT ANTENNAS? (TIM) THOSE ARE ANTENNAS. THOSE ARE THE ANTENNAS AND THE FEMALES HAVE A LITTLE BIT LONGER THAN
THE MALE. THIS ONE HE’S LOST. HE MIGHT A LOST ONE IN THE FIGHT. AND BECAUSE HE WAS IN WITH OTHER
ONES AND SO HE TURNED AROUND WHEN I WAS ACTUALLY PICKING A
ROACH I WAS PICKING THEM UP TO SEE WHO WOULD HISS AND HE HISSED THE MOST SO I’M FIGURING HE PROBABLY THE DOMINANT ONE. (CRAIG) RIGHT. (TIM) MAYBE HAD A
LITTLE FIGHT GOING ON. (CRAIG) RIGHT SO YOU’VE TALKED ABOUT THESE
GUYS MAKING NOISES. WHAT OTHER KINDS OF INSECTS ARE GOING TO
MAKE SOME NOISES AS WELL? (TIM) WELL YOU GET YOU GET CRICKETS THAT’LL MAKE NOISES. (CRAIG) AND THAT’S RUBBING THEIR HIND LEGS TOGETHER. (TIM) THE CICADAS THEY MAKE NOISES. SO THEY
THERE’S A LOT OF DIFFERENT ONES BUT ONLY THESE HISSING
COCKROACHES ARE SOME TWENTY SPECIES OF HISSING COCKROACHES
ON MADAGASCAR. SO THEY ACTUALLY
MAKE THAT SAME NOISE. (TIM) NOW YOU ALSO BROUGHT
ANOTHER. (TIM) I DID. (DONNA) IS IT AN INSECT OR SOMETHING FOR US TO SEE. (TIM) HE’S A POD. HOLD ON. (DONNA) HE’S A POD. HE’S A TOUGHY TO GET A HOLD OF. (DONNA) NOW THESE GUYS WON’T GET OUT WITHOUT THE LID ON WILL THEY? (TIM) NO. THEY WONT GO FAR. LET ME SEE IF I CAN FIND HIM. HOLD ON. THERE WE GO. (CRAIG) HE’S GOT A NECKLACE. (DONNA) AWW HE’S GOT A NECKLACE ON. (TIM) WELL IT’S MARDI GRAS. (CRAIG) AH MARDI GRAS. (DONNA) WHAT CREATURE IS THIS AND WHERE CAN WE FIND IT. (TIM) THIS IS OUR MILLIPEDE. OOPS GOT IT ON THE BACK END. THAT’S ALRIGHT. BUT THAT’S ALRIGHT. I WON’T TELL YOU HOW IT GOT THE BEADS BUT THE KICK LINE IN THE CONGA WAS TO DIE FOR. BUT THIS IS THAT OTHER INSECT. IT’S WELL NOT AN INSECT. IT’S A POD. IT’S GOT.. IT’S A MILLIPEDE IT DOESN’T HAVE
A THOUSAND LEGS. IT’S ONLY GOT ABOUT FOUR HUNDRED. AND BUT HE’S REALLY PRETTY COOL
THEY’RE THEY’RE ACTUALLY ONE OF THE FIRST TO COME OUT OF THE
OCEAN. DURING ABOUT FOUR
HUNDRED AND FIFTY MILLION YEARS AGO SO FIRST TO TAKE THE LAND
WHERE THE MILLIPEDES AND CENTIPEDES. (CRAIG) WHAT CHARACTERIZES THIS AS A POD COMPARED TO AN INSECT? (TIM) THE NUMBER OF LEGS. (CRAIG) SO INSECTS HAVE SIX. (TIM) SIX AND THE NUMBER OF BODY PARTS BECAUSE HE’S GOT SEVERAL SENTIMENTS AND IF YOU NOTICE IF
WE CAN GET A GOOD LOOK AT HIM OR HOLD HIM YOU CAN SEE THE THE LEGS MOVE. (DONNA) HOW THEY MOVE YEAH. (TIM) THE FIRST FEW SEGMENTS WILL HAVE ONLY TWO LEGS ON EACH SECTION
AND THEN FROM FIVE BACK THEY’LL HAVE FOUR LEGS ON EACH SECTION.
(CRAIG) INTERESTING (TIM) AND GO AHEAD. (DONNA) HOW
LARGE IS HE GOING TO GET? (TIM) THIS ABOUT AS BIG AS HE’LL GET. SIX
MAYBE SEVEN INCHES. HE’S NORTH AMERICAN SO HE’S
YOUR FIND, CRAIG YOU SAID YOU FOUND SOME. (CRAIG) OH WE WERE IN LETCHWORTH WITH THE BOY SCOUTS AND THE GUY HAD ONE A LITTLE BIT SHORTER THAN
THAT BUT IT WAS ABOUT AS BIG AROUND AS THAT ONE. (TIM) WELL SAME KIND OF LOOK TO IT SO YOU FIND THEM ALL OVER BUT MOSTLY THEY’RE
TROPICAL THEY BECAUSE WELL AS MOST INSECTS OR MOST
PODS LIKE THIS THEY’LL LIVE BETTER IN TROPICS, WARM WEATHER. SAME WAY WITH THE ROACHES. THE
ROACHES WILL DIE IN COLD WEATHER BECAUSE IT WON’T BE ABLE
TO BREATH. (CRAIG) OKAY. (DONNA) NOW DOES THE MILLIPEDE HAVE ANY DEFENSE MECHANISMS? YOU TALKED ABOUT THE HISSING FOR THE
COCKROACHES. (TIM) AS A MATTER OF FACT IT DOES. IF YOU COULD SEE ON THE ENDS OF
MY FINGERS YOU’LL SEE THE
LITTLE YELLOW AND HAVE THEY SECRETE FROM THEIR SEGMENTS. AND
IT’S USUALLY SOME KIND OF A TOXIN FOR HUMANS IT’S NOT
ANYTHING MORE THAN IT DISCOLORS THE SKIN. (CRAIG) WE KNOW FIRST AID
SO. (TIM) BUT YEAH SO I’M I’M GOOD TO GO I’M SURE. BUT FOR OTHER
INSECTS IT’S A TASTE SOME OF THEM HAVE SOME MILLIPEDES HAVE REALLY TOUGH TOXIN SO AS SO AS THEY A TASTE IT ITS A NEURO TOXIN. THEY’LL STOP BITING IT AND THEN BUT IT ALSO THESE GUYS
ROLL UP INTO A BALL TO TRY TO PROTECT THEIR LEGS AS THEY GO
ALONG AS WELL. (DONNA) WELL TIM I WOULD
SHAKE YOUR HAND BUT YOU HAVE THAT THING. (CRAIG) I WILL THANKS TIM. (DONNA) IF YOU WOULD LIKE TO LEARN MORE

Parasite tales: The jewel wasp’s zombie slave – Carl Zimmer

Parasite tales: The jewel wasp’s zombie slave – Carl Zimmer


Translator: Andrea McDonough
Reviewer: Bedirhan Cinar I would like to introduce you
to my favorite parasite. There are millions that I could choose from and this is it: it’s called the jewel wasp. You can find it
in parts of Africa and Asia. It’s a little under an inch long, and it is a beautiful looking parasite. Now, you may be saying to yourself, “This is not a parasite. It’s not a tapeworm, it’s not a virus, how could a wasp be a parasite?” You are probably thinking
about regular wasps, you know, the ones that build
paper nests as their house. Well, the thing is that the jewel wasp makes its house inside
a living cockroach. Here’s how it happens. A jewel wasp is flying around,
looking for a cockroach. When it sees one, it lands
and bites on its wing. So, I’ll be the cockroach. Be-wha! Bewha! And the cockroach starts shaking it off, “Get away from me!” The wasp very quickly starts
stinging the cockroach. All of a sudden, the cockroach can’t move, for about a minute. And then it recovers and stands up. It could run away now, but it doesn’t. It just doesn’t want to. It just stays there. It’s become a zombie slave. Again, I’m not making this up. The wasp goes off, it walks away and finds a hole and digs it out, makes it into a burrow. It walks back. This can take up to half an hour. The cockroach is still there. What do we do now? The wasps grabs onto one of the antenna, bites down on it, of the cockroach, and pulls the cockroach. And the cockroach says, “Alright,” and walks like a dog on a leash. The wasp takes it
all the way down into the burrow. The cockroach says, “Nice place.” The wasp takes care of some business and then goes and leaves the burrow and seals it shut, leaving the cockroach entombed
in darkness, still alive. The cockroach says, “Alright,
I’ll stay here if you want.” Now, I mentioned that
the cockroach took care, ah, the wasp took care
of a little business before it left the burrow. The business was laying an egg on the underside of the cockroach. The egg hatches. Out comes a wasp larva. It looks kind of like
a maggot with big, nasty jaws. It chews a hole into the cockroach and starts to feed from the outside. It gets bigger,
like you can see over here. And then when it gets big enough, it decides to crawl into the hole, into the cockroach. So now it’s inside
the still-living cockroach and the cockroach doesn’t mind much. This goes on for about a month. The larva grows and grows and grows, then makes a pupa,
kind of like a cocoon. Inside there it grows eyes, it grows wings, it grows legs, the cockroach is still alive,
still waiting. Finally the wasp is ready to leave, and that’s when the cockroach finally dies because the fullly-formed adult wasp crawls out of the cockroach’s dying body. The wasp shakes itself off, climbs out of the burrow, goes and finds another wasp to mate with to start this whole, crazy cycle again. So, this is not science fiction, this happens every day,
all over the world. And scientists are
totally fascinated by this. They’re just starting to figure out
how all this happens. And, when you really start
to look at the science of it, you start to kind of respect
this very creepy wasp. You see, the thing is that
when it attacks the cockroach, it’s not just stinging wildly, it delivers two precise stings. It knows this cockroach’s nervous system like you know the back of your hand. The first sting goes to that spot there, called the “walking rhythm generators,” and, as you can guess, those are the neurons that send signals to the legs to move. It blocks the channels
that the neurons use to send these signals. So the cockroach wants to go,
it wants to run away, but it can’t because
it can’t move its legs. And that lasted for about a minute. This is really sophisticated pharmacology. We actually use the same method, a drug called Ivermectin, to cure river blindness, which is caused by a parasitic worm that gets into your eye. If you take Ivermectin,
you paralyze the worm using the same strategy. Now, we discovered this in the 1970s, the wasp has been doing this for millions of years. Then comes the second sting. Now the second sting actually hits two places along the way. And to try to imagine how this can happen, I want you to picture yourself with a friend who’s got a very long, very, very scary looking needle. And your friend, or at least you thought he was your friend, sticks it in your neck, goes into your skull, stops off at one part of your brain and injects some drugs, then keeps going in your brain and injects some more. These are two particular spots, marked here, “SEG”, and you can see the tip of it in the brain, marked “Br”. Now, we can do this, but it’s really hard for us. It’s called stereotactic drug delivery. You have to put a patient in a big metal frame to hold them still, you need CAT Scans to know where you’re going, so you look at the picture and say, “Are we going the right way?” The jewel wasp has sensors on its stinger and scientists think that it can actually feel its way through the cockroach’s brain until it gets to the exact, right place, and then penetrates an individual neuron and then delivers the goods. So, this is quite amazing stuff, and what seems to happen then is that the wasp is taking away the control that the cockroach has over its own body. It’s taking away the cockroach’s free will. We didn’t really appreciate that cockroaches have free will until this wasp showed us. And, we have no idea how it’s doing this, we don’t know yet what the venom has in it and we don’t know which circuits it’s hitting in the cockroach’s brain, and I think that’s why this is, most of all, my favorite parasite because we have so much left to learn from it. Thank you very much.

实验:臭氧能杀死蟑螂吗?

实验:臭氧能杀死蟑螂吗?


A fan from Taiwan recently emailed me He said that because he just had a baby So he’s been doing research on sterilization He found online that ozone has such function So he bought an ozone machine He also learned that when the ozone density is high, it’s harmful to human body So he caught a mouse to test He put the mouse and ozone machine in a box Then tested for half a day Guess what happened to this mouse This mouse committed suicide Do you believe it Things That Make Animals Suicide What a cruel torture Then he said he wanted to know Can ozone kill some pests Such as cockroaches He wanted me to test it It sounded like a good idea to me. So let’s try it today on Ozone’s ability to kill cockroaches To test whether ozone can kill cockroaches I placed an order online to get an ozone machine It can make three grams of ozone per hour Sounds very light But you need to know The density of the gas is very low So three grams is actually a lot. Then i will Put cockroaches in this jar Do you still remember this jar? Here is an entrance, here is an exit It was originally tested for the harm of cigarettes We let a roach smoke 20 cigarettes After putting the roach in I will plug the tube of the ozone machine in from here So that ozone can go in While having the exit to Connect with the outside So that gas can circulate to eliminate the factor of suffocation Also because the jar is small So the ozone density will be high Then let’s start the experiment There are two healthy American cockroaches in the jar Why put two It’s to ensure that observations are more informative You can see This jar is connected through this tube to the ozone machine Next Let’s start the ozone machine One minute later Acting normally, but seem agitated Three minutes later Wings start to flap Five minutes later Start to fall off more often 10 minutes later Climinb ability is weakened 15 minutes later Mobility is weakened obviously 20 minutes later Out of balance 30 minutes later Hard to flip over 40 minutes later Moving very slowly Interval twitching 50 minutes later Can barely move One hour later Alive, but sruggling After an hour of ozone making Two roaches in the jar Look dead But does this mean that ozone can kill roaches(at home)? Of course not Because when this type of ozone machine is used at home It is impossible to achieve such a high indoor density If it really reaches that high Even if you kill the roaches People might be expected to die the same way And in the same room Actually I had put some other roaches This enclosed room is only seven or eight square meters So the ozone density will not be very low. But those roaches are all safe and sound I also did some research There is indeed relevant information indicating That ozone is used in agriculture Used to kill some pests But usually very small pests Like aphid Ozone is more useful for sterilization than killing pests So expecting to use this ozone machine to eliminate cockroaches is not realistic As for what’s mentioned by the fan in the beginning Why the mouse committed suicide I think it’s because it was in a small confined space Very high density of ozone Makes the poor mouse feel very uncomfortable So he finally chose to end its life The fact is that when the ozone density is relatively high, It’s really harmful to the human body When I used this machine I could smell it very clearly Very peculiar taste So if you want to use these machines at home It ’s better to be cautious The advice is that when using it People and pets had better leave the house Ok That’s it for today’s video What else would you like to see for a pest control product review Tell me in the comments below See you next time Update: the next day, two roaches in the jar both died, but the roaches in the box were normal Footage of entire activities in the jar
