Not sure. The machines can adjust power and time of exposure to get the results they want. They can also use the machines to kill all DNA so that nothing survives. They use that for disposal after testing so that nothing is contaminated. The bug growing and distributing is a whole different industry, we just sell machines to them. They also use our machines to sterilize blood that is donated and medical weed. X-rays are far safer for those things than nuclear radiation. @@ano_nym
This is why it's so important to not be reactionary each time there is a seemingly ridiculous line item in a government's budget. Sure, waste and abuse exists and should be dealt with, but programs like this, though they may sound silly, are so unbelievably important!
This man has the most damn consistent upload schedule in the entirety of youtube, like seriously, a video every single monday for nearly 10 whole years is amazing! edit: tf is happening in the replies
This is a good chunk of science, using refrigeration to immobilize mass amounts of flies to make them easier to deal with. Using radiation to sterilize them, and then evolutionary biology models show why this works. Just brilliant.
@thehoneyseals tbh he had some guest uploaders before so it's not really fair to say he had 10 years of consecutive uploads by himself. So maybe closer to like 506 weeks that Tom did, not 521
I actually found a bunch of these guys one day at my university. I was working in a biochemistry lab which studies fruit flies at the time. We called some invasive species / wildlife hotline to report it and they seemed concerned. Later, we got an email that informed us about the sterile fly release program and thanking us for our vigilance.
Woah! Me and my Dad had a hard time finding firewood because the farms that usually sell it were shut down to avoid breeding these flies! Incredible to see you cover this, Tom, it hits close to home for me! Literally!
@@Erteywie It is for beetles in my neck of the woods. (Ontario Canada) The provincial parks rake in the cash forcing people to buy their crappy local (usually wet) firewood for camping.
There's actually several different harmful/invasive species behind the "don't move firewood" rules - Emerald Ash Borer, Dutch Elm Disease, Chestnut Blight, Sudden Oak Death, Spotted Lanternfly, and many more! There are places where all the trees of a susceptible species have been killed by one invasive pest/disease.
As a pilot watching this I went down the biggest rabbit hole attempting to figure out whether or not that was a Queen air or a King air. It's a Model 65-A90-1. Which is essentially a King air with a queen air cabin. I have no idea why anyone would want such powerful engines on an unpressurized airframe that can't go higher than 12,500. I guess if the purpose is to stay at 2000 feet to drop flies then I guess its perfect for the job.
I was curious about that as well but without the aircraft registration it's going to be tricky to see if that plane is original or just picked up on the second hand market and was good enough.
From my understanding, all their (Dynamic) King Air A90's are mostly US Army VIetnam War vintage and were configured with large cargo doors. The are the contractors flying this program, but they also lease out the same planes when not on this contract to fly other things like aerial survey missions, which I have gone up in one of their 90's. They have a good number of them. You can see some on Google Earth at their home base in Bridgewater, VA
probably best to have an overpowered engine for the job than the bare minimum and risk some sort of failure, because these planes are probably reused year after year. I would think.
I grew up in California and those insect detection traps were constantly in the background of my childhood. I made a game of it, like looking for easter eggs, because they could be anywhere, even on private property. (Obviously I wouldn't mess with them) Now we get to see what those traps are used for.
When I was in high school one of those planes flew over... and suddenly the entire school was full of flies for ~30 minutes or so until they fully dispersed. Cool to know this project is/was effective and still going.
Im going to miss you Tom. You really are top of your game, but im really glad youre going to take some time for yourself now. I want to wish you all the best from the bottom of my heart, and sincerely thank you for all you have sacrificed over the years to provide us with top tier entertainment. HIP! HIP!....

There are many places trying stuff similar to this but for mosquitos that can spread human diseases, as well. IIRC, they use other techniques to make them sterile (if I remember correctly, using some enzyme knockout mosquitos and providing the jutrient they should be able to synthesise while in the breeding lab)
This is similar to the joint U.S.-Panama programme that drop flies in Panama against the Screwworm. Not an easy task but one that requires constant effort to make it work.
Thanks for the read. Found out they cut off the program at Panama (15 million usd per year) because south American countries hate each other and don't want to pay for a certain percentage of the bill to eradicate screworms. They can't agree on how tk calculate which countries pool what amount for the sterile screworms. They should just do it based on the percentage of livestock a country holds compared to south American total livestock.

I remember as a little boy on a road trip with my pa going thru a checkpoint in the middle of the desert. I asked pops why they asked us if we had any fruit, don’t remember what he said but that must have been twenty years ago. We’ve been fighting that fly for a long time.
I thought it said flyers (as in leaflets) similar to how the Israelis dropped flyers telling civilians to flee Gaza city as it was about to get bombed to hell. I thought oh sh*t what's kicking off now?
This video was so fulfilling for me! Thank you so much! These planes fly over my house daily and I always appreciate them. I emailed the company once to ask all of the questions I had about the process and they obliged some small snippits (thank you!) . But this video fully answered all of the blanks in my head!
The males and females have to have some way of finding each other. For some insects, that's pheromones, for some, they meet on a food source (food for them or their larvae), and some make noise to attract mates. Some larger insects than fruit flies find each other visually.
Seems very well researched and many MANY angles of safety are being taken. Good to see lessons from past mistakes are being fixed today. I really appreciate they are not importing a new insect to combat an invasive one.
Growing up in LA in the 80s, there would be regular overflights of helicopters spraying malathion (sp?) at night to kill fruit flies. In addition to being toxic, it would ruin the paint on cars. I don't even want to imagine what playing in grass covered with the stuff did to me. Fly on, sterile flies. I'm rooting for you.
At some point they used to spray DDT... but I guess nobody old enough to remember survived this one. Yesterday's solutions are today's problems! The advantage with the flies is that their life expectancy is only a few days/weeks.
one of the most... viscerally uncomfortable and fascinating videos i've ever watched. this is a great reminder that no matter how "gross" a safety measure may sound, it's important and does a lot of work! a lot of people can be turned off by ideas for change that sound or look uncomfortable, even though they can do a lot of good.
It is videos like this I wish more people would see. People just have no clue about all of the behind-the-scenes activities that our federal and local governments have to do for the welfare of our citizens. Everyone always complains about how their taxes are used, because they have no idea about all of the things like this.
I remember as a kid living in lakewood California in the late 80s having Hueys flying over at night spraying malathion and having local PD helicopters trying to stop them. Surprising they didn't hit each other. All in a effort for pest control.
Same here. You had to cover your cars because the malathion would hurt the paint. It was interesting to watch them fly in formation coming and going across an invisible matrix to complete their flight plan.
Thats wild, i had similar incident in suburbs of NY for mosquitos. I remember running inside when i saw the truck coming, i dont remember if they used planes but possibly. Back in the 90s or late 80s iirc
We didn't have police helicopter interceptors in my neighborhood but I do remember the warnings of overflights and the damage to cars, the latter of which was fodder for late-night talk show hosts.
In the west side of Argentina we have the same problem and we also drop sterilized Mediterranean fruit flies, but we go about it in a simpler way. We package the eggs into a paper bags and drop them from planes. Those bags are marked and people know that, if one lands on their property, they have to open the bag and place somewhere high and shady, like the canopy of a tree. The flies then hatch and spread themselves :)
Wouldn't work in the US. Too many crazy people and/or people who want to make things difficult for no reason. They would go out of their way to destroy any bags they came across.
Tom.. back in the 70's there was a huge outbreak. As a kid I remember the helicopters flying over in groups of 3 spraying poison. You would hear them coming and dart inside. The next day you would have to wash your vehicle because it has an orange coating on it. Interesting how now we can drop the flies themselves. Thanks for the story.
Short refrigeration is a very good technique to immobilize insects for macro photography. You can manipulate them into all sorts of poses when they are completely docile at low temperature. Plus if the temperature is low enough and there is environmental moisture you get dew drops on them for sparkling effects. Then after the photoshoot the stars can be released without harm.
As a kid in Silicon Valley, California, I remember helicopters spraying suburban areas with Malathion to prevent Mediterranean Fruit Flies from spreading in California in the 1980’s, but this was around ‘79 or ‘80, not 1986. It was controversial at the time, with people complaining about the health effects of the government spraying pesticides over populated areas and people complaining about the droplets staining the paint on their cars. I certainly remember seeing the little spots on cars.
I lived in San Gabriel from 88 to 91 when the Malathion spraying started trying to combat the Medfly. It started out with two Huey's & quickly became 10 plus 2 cop choppers flying wingman. You had to take your pets inside & cover your cars. I lived at the bottom of San Gabriel Ave which was their turn around spot, it sounded like I was back in Nam, the whole house would shake when they did their formation 180. The crazy thing is that I live in the Idaho Rockies now & see Medfly's here in the summer.
I work in biosecurity in Australia and Medfly are one of the pests we're constantly watching out for. This is such a great idea for control once something gets established and I hope it continues to work.
so this is different to the fruitflies we have in Australia? Is that why we don't use a program like this to wipe out our fruitflies, instead of just limiting what can be carried across state borders?
@@mehere8038 We don't have Med-Fly in eastern Australia, so the limits on state borders are designed to keep it out, whereas a program like this could be more effective in eradicating or controlling a population that's already established. This would take a lot more resources and money than prevention though, so that's why we have the border checks and surveillance programs.
thank you Tom for doing everything you could to not make this a clickbait title, I doubt most youtubers could resist the temptation have "radioactive flies dropped over your head" in the thumbnail.
If you watched the news back in the 1980s, the medfly issue was huge and made national news. It's awesome to see the long them management of the issue!
Fruit flies impact agriculture the way plagues impacted medieval cities: "in the wild" their populations would be scattered and isolated and controlled by natural threats (insectivores/etc), but large-scale monocrops just so happen to provide an ideal scenario for them to reproduce _without_ their natural controls.
I remember when they were making these at MTSU back in 2003. They were creating sterile fruit flies and then eventually had to release them, and there were so many around the dumpsters it was something to behold. They of course died out within a week, but it was quite eyebrow raising back then. The extremely bright red eyes on them was something I remember. Local non-invasive flies don't have those red eyes.
There are two unforeseen consequences of irradiating fruit flies. One is that you end up with a teenager bitten by a radioactive fly, and he becomes a superhero. The other is a giant mutant fruit fly that wreaks havoc upon California.
These two consequences cancel each other out though since flyman will valiantly fall while taking down the giant fly removing both of them from the ecosystem and providing footage for dozens of high school film projects in the process.
Something similar is done in South Africa, not sure to what degree, where sterile male anopheles mosquitos are released in malaria hot spots. Fascinating to see this being done overseas as well.
As a lifelong California resident I can tell you that this program is so vital I’m not old enough to remember when they would make every vehicle entering the state declare any and all fruit in the car. But I have seen the stations that they put on the border. They still staff them too, just in case.
This was incredibly fascinating! I definitely remember having Medfly infestations in the 80’s (we had fruit trees.) I wondered what happened to them! This is such a great program!
4:30 this Chad spitting bars The flies are screened under a UV light looking for the presence of the marker dye so we're able to identify and differentiate a sterile fly from a wild fly
I live in the LA area and teach aviation to new pilots. I see those planes all the time zig-zagging throughout the area. Some of the flies end up on the window. I will be able to identify where it came from. It’s awesome to see the behind-the-scenes of what they do.
In Texas back in the 70’s we had an epidemic of screw worm flies. There was a program such as this one that dropped adult sterile male screw worm flies. Eventually the screw worm flies were eradicated.
I hope Tom Scott's last video is a banger (It will be) but give us something raw. Give us something you are REALLY passionate about; maybe even use a swear. Please don't end an era on a "Thank You video"
I'm curious how that affects the rest of the ecosystem. I'm sure there are animals (birds, reptiles, other insects) that feed on those flies, so does the treatments done to sterilize and mark them cause any issues to the creatures that ingest them?
like he said its not actually a lot 1 extra insect every 20 square metre in specific areas of a state does not equal to a destabilisation of the ecosystem.

Can you expand on the "viscerally uncomfortable" - if you don't mind?
Maybe you love insects, or just the exact opposite?
It is videos like this I wish more people would see. People just have no clue about all of the behind-the-scenes activities that our federal and local governments have to do for the welfare of our citizens. Everyone always complains about how their taxes are used, because they have no idea about all of the things like this.
Absolutely insane combination of maths, tech, science, and nature. Quite possibly one of the most ingenious solutions I've learned about.
Hey, kid.
(this has been used for decades with a variety of species)
I remember as a kid living in lakewood California in the late 80s having Hueys flying over at night spraying malathion and having local PD helicopters trying to stop them. Surprising they didn't hit each other. All in a effort for pest control.
Same here. You had to cover your cars because the malathion would hurt the paint. It was interesting to watch them fly in formation coming and going across an invisible matrix to complete their flight plan.
Yea remember that??? I lived in Glendora during that time.
Thats wild, i had similar incident in suburbs of NY for mosquitos. I remember running inside when i saw the truck coming, i dont remember if they used planes but possibly. Back in the 90s or late 80s iirc
We didn't have police helicopter interceptors in my neighborhood but I do remember the warnings of overflights and the damage to cars, the latter of which was fodder for late-night talk show hosts.
In the late 90s i lived in a suburb of houston/tx and there were trucks spraying insecticides in the streets every night.
I had no idea this was going on thanks for bringing this to everybody's attention
Wow. When I’ve flown into LAX I’ve heard these planes on the ATC frequency - callsign “Medfly” and always wondered what they were… Thanks Tom!
In the west side of Argentina we have the same problem and we also drop sterilized Mediterranean fruit flies, but we go about it in a simpler way. We package the eggs into a paper bags and drop them from planes. Those bags are marked and people know that, if one lands on their property, they have to open the bag and place somewhere high and shady, like the canopy of a tree.
The flies then hatch and spread themselves :)
Wouldn't work in the US. Too many crazy people and/or people who want to make things difficult for no reason. They would go out of their way to destroy any bags they came across.
Great video Tom. Going to miss your weekly educational videos.
this is the perfect kind of thing for a government to do. incidentally, also the perfect kind of thing for a Tom Scott video
I misread "flies" as "files" and was very curious to see why some pre-fax document delivery service was still in use.
thanks for sharing behind of it!
Tom.. back in the 70's there was a huge outbreak. As a kid I remember the helicopters flying over in groups of 3 spraying poison. You would hear them coming and dart inside. The next day you would have to wash your vehicle because it has an orange coating on it. Interesting how now we can drop the flies themselves. Thanks for the story.
Had one of those government insect traps hanging outside our apartment building for months last year and always wondered what it was for.
Short refrigeration is a very good technique to immobilize insects for macro photography. You can manipulate them into all sorts of poses when they are completely docile at low temperature. Plus if the temperature is low enough and there is environmental moisture you get dew drops on them for sparkling effects. Then after the photoshoot the stars can be released without harm.
Doctors do it too. But there's more to the story.
That's how??? 😂i always wondered how they did it, found bunch of flies mating pictures macro photography in Facebook
What a fascinating process 👏👏👏
Is it possible the person piloting that plane holds the record for the number of passengers on board?
If you count bacteria as passengers every pilot had billions of passengers.
@@k1ry4n not sure why, but I draw the line at the Animalia kingdom
We don't have to miss Tom, he still has his podcasts and such.
its amazing how we're able to do all this
Always good to see your videos
Hey Tom Scott! It was really nice meeting you in the line for revolution at magic mountain!
As a kid in Silicon Valley, California, I remember helicopters spraying suburban areas with Malathion to prevent Mediterranean Fruit Flies from spreading in California in the 1980’s, but this was around ‘79 or ‘80, not 1986. It was controversial at the time, with people complaining about the health effects of the government spraying pesticides over populated areas and people complaining about the droplets staining the paint on their cars. I certainly remember seeing the little spots on cars.
Government is always up to no good. DDT was a great idea until they realized it was a giant mistake
Super interesting! Thanks to everyone who helped put this together and do all this.

I lived in San Gabriel from 88 to 91 when the Malathion spraying started trying to combat the Medfly. It started out with two Huey's & quickly became 10 plus 2 cop choppers flying wingman. You had to take your pets inside & cover your cars. I lived at the bottom of San Gabriel Ave which was their turn around spot, it sounded like I was back in Nam, the whole house would shake when they did their formation 180. The crazy thing is that I live in the Idaho Rockies now & see Medfly's here in the summer.
uh oh
I work in biosecurity in Australia and Medfly are one of the pests we're constantly watching out for. This is such a great idea for control once something gets established and I hope it continues to work.
so this is different to the fruitflies we have in Australia? Is that why we don't use a program like this to wipe out our fruitflies, instead of just limiting what can be carried across state borders?
@@mehere8038 We don't have Med-Fly in eastern Australia, so the limits on state borders are designed to keep it out, whereas a program like this could be more effective in eradicating or controlling a population that's already established. This would take a lot more resources and money than prevention though, so that's why we have the border checks and surveillance programs.
thank you Tom for doing everything you could to not make this a clickbait title, I doubt most youtubers could resist the temptation have "radioactive flies dropped over your head" in the thumbnail.
How wild is this! Hats off to those that put this forward to the government
Don't try this with Turkeys. (I heard a news broadcast about this on a Cincinnati radio station)
I had no idea fruit flies had such a negative impact on agriculture! 😯
the farmers are just idiots though, they could just grow vegetables when there's too many fruit flies.
If you watched the news back in the 1980s, the medfly issue was huge and made national news. It's awesome to see the long them management of the issue!
Fruit flies impact agriculture the way plagues impacted medieval cities: "in the wild" their populations would be scattered and isolated and controlled by natural threats (insectivores/etc), but large-scale monocrops just so happen to provide an ideal scenario for them to reproduce _without_ their natural controls.
This makes a lot of sense, thank you for the info!@@Stratelier
Australia has draconian fruit-fly control laws, both the national and state borders, for a good reason. And they work and no-one complains about them.
Fond memories of my encounters with the Californian fruit police at the Oregon border.
I remember when they were making these at MTSU back in 2003. They were creating sterile fruit flies and then eventually had to release them, and there were so many around the dumpsters it was something to behold. They of course died out within a week, but it was quite eyebrow raising back then. The extremely bright red eyes on them was something I remember. Local non-invasive flies don't have those red eyes.
Oh my god now I know why we have these crazy waves of medflies!
Is this what they call a "fly over"?
There are two unforeseen consequences of irradiating fruit flies. One is that you end up with a teenager bitten by a radioactive fly, and he becomes a superhero. The other is a giant mutant fruit fly that wreaks havoc upon California.
You know most of your food is irradiated to kill bacteria...
These two consequences cancel each other out though since flyman will valiantly fall while taking down the giant fly removing both of them from the ecosystem and providing footage for dozens of high school film projects in the process.
It's Cali, no one would notice
Jeff Goldblum is that you
Those are consequences of radioactive fruit flies. But irradiating them doesn't make them radioactive.
Something similar is done in South Africa, not sure to what degree, where sterile male anopheles mosquitos are released in malaria hot spots. Fascinating to see this being done overseas as well.
As a lifelong California resident I can tell you that this program is so vital I’m not old enough to remember when they would make every vehicle entering the state declare any and all fruit in the car. But I have seen the stations that they put on the border. They still staff them too, just in case.
Those arent 'just in case'....they daily play a vital role in excluding so many plant and animal diseases.....
Fantastic video as always Tom, well done!
Time's fun when you're having flies. - Kermit the Frog
Time flies like an arrow, fruit flies like a banana - Groucho Marx
Good fly jokes
This was incredibly fascinating! I definitely remember having Medfly infestations in the 80’s (we had fruit trees.) I wondered what happened to them! This is such a great program!
5:39 the pilots wouldn't be able to focus on their job with the distraction of an incredibly charming British man on the plane with them
4:30 this Chad spitting bars
The flies
are screened under a UV light
looking for the presence of the marker dye
so we're able to identify
and differentiate a sterile fly
from a wild fly
I read this as "files" instead of "flies", imagine dumping a lot of paper
At 5:45, you can see some pupae are still present. I wonder if any of those would still be viable, and if so, do they have any chance of developing? 🤔
Surface = Good Reasons. Reality = Not Good Reasons.
what are the bad reasons sir
Crazy! I'm not sure why we don't do similar things here in the PNW for the apple maggot flies we have here.
$$$
It must be fun for the people working here to able to share their work with potentially millions of viewers.
I live in the LA area and teach aviation to new pilots. I see those planes all the time zig-zagging throughout the area. Some of the flies end up on the window. I will be able to identify where it came from. It’s awesome to see the behind-the-scenes of what they do.
I’ll miss you Tom Scott, definitely one of my favorite educational TH-camrs 😭😭😭😭 ❤❤❤❤
How about... now hear me out... we make friggin mosquitos extinct
As a resident of california: I'm happy to hear this. I hate those damn flies. They don't just ruin big crops they ruin gardens.
I think they're dropping them right over my house. It was ridiculous this year.
In Texas back in the 70’s we had an epidemic of screw worm flies. There was a program such as this one that dropped adult sterile male screw worm flies. Eventually the screw worm flies were eradicated.
I hope Tom Scott's last video is a banger (It will be) but give us something raw. Give us something you are REALLY passionate about; maybe even use a swear. Please don't end an era on a "Thank You video"
iirc he won't stop making videos... it's just the schedule that won't be as consistent
“Irradiating something does not make that thing radioactive!”
**Neutron radiation enters the chat**
I'm curious how that affects the rest of the ecosystem. I'm sure there are animals (birds, reptiles, other insects) that feed on those flies, so does the treatments done to sterilize and mark them cause any issues to the creatures that ingest them?
like he said its not actually a lot 1 extra insect every 20 square metre in specific areas of a state does not equal to a destabilisation of the ecosystem.
Didn't the video open saying these flies are invasive? Nothing is eating them, or at least not enough.
@chatboss000 well they are sterile, and have a lifespan of like a few months, so I don't think it's that much of an issue
Seems like a short term solution to a long term problem
What's a long term solution then?
Excellently done, Tom!
