To put into perspective why the bacterium is so damaging to olive farms specifically: it can take up to 5 years for a tree to begin producing fruit, and from then on their growth is extremely slow. Now imagine losing half your crop.
thankfully they live really long, theoretically the tree under which Jesus (supposedly) said his final prayer could still be alive. Unless it got a clotting disorder along the way, of course.
In 2019, one iGEM team tried to fix this problem for olive farmers by designing a bacteriophage that would firstly infect the Xylella cells to make them produce more phages (like they naturally do) but then, before they died, force them to produce signalling molecules that would radically ramp up the plants innate immune response to make them more hardier and help the phage fight the bacterium. Also, the phage was designed with proteins on its capsid that would stick it to chitin, so that they would be transferred from plant to plant by the mouth parts of the bugs to basically spread the viral vaccine everywhere the bugs go. But I don't know if they ever got the permission to actually test their little viral bioweapon in the open.
That'll be great. I hope their research has gone further enough now to get clearance for deployment. I guess we'll just wait and see. They've done multiple trials in enclosed environments, right? Attacking the bacteria directly is a better option than, say, launching an all-out war against that particular bug specie. The bacteria may just find a new host and waste our efforts.
The NickBlaster Perhaps they’re more like ticks. I got Lyme Disease from a tick once (very glad about amoxicillin getting rid of it for me early). So, I really should have thought of that first.
I appreciate sci-show not jumping on the 'villify the bugs' train, even when the bugs are actually causing (accidentally) a problem. Keep doing the good work y'all.
_Xylella fastidiosa_ confuses me. Most pathogens do *not* want to kill their host, as they no longer have a place to feed or live. Highly lethal illnesses are often a sign of something crossing the species barrier, but... that doesn't seem plausible here, as it affects basically ALL THE PLANTS. Does it just count on rapid spread to keep ahead of host die-off?
because it is spread so much to so many plants, the bacteria that replicate ASAP, infects the whole plant and gets picked up by a spittlebug will spread *much* better then the same bacteria that replicates slowly and allows the plant to live yeah it just counts on rapid spread to keep ahead of host die-off
No it really isn't. Remember evolution is trial and error. It takes a while to kill an olive tree, the bacteria doesn't care too much about keeping itself alive but replicating as many as possible, as quickly as possible, becoming spread and therefore numerous quickly. This then gives rise to problems such as killing the host. It is hard to tell if infections will get less severe to allow a smaller culture of bacteria to survive longer but as they have already invested so much energy into spreading quickly it might take a long time before they accidentally learn that keeping the host alive increases longevity.
Samson Cooper Fair! I had incorrectly assumed a more advanced age for the species with the current disaster being due to some other factor. For a fairly new species of bacterium, that makes sense.
Yeah, the area I'm in treats all spittle bugs like invasive pests. There've even been a few years where the local municipality has gone on extermination waves. It's crazy to see every plant in your vicinity covered in gross little bubbles.
Just spotted some in my mom's back yard. She had just seen a segment about it (not the bugs in particular) but claiming it was something extremely harmful to plants, animals, and humans. I also have had tons of leafhoppers at my house, not far from her, for several years. Not sure if they're related. I sure hope they aren't the bacteria spreaders.
I had some spittlebugs and accidentally found an organic remedy. I purchased beneficial nematodes for my garden to combat other bugs. I got the sc variety (Steinernema carpocapsae). The nematodes generally fight only soil based bugs but to apply them you need to use a hose sprayer. I sprayed right over them. In 2 days my green little spittlebugs had turned a mottled yellowish orange. Not a one left after a week. Not sure if it would work with other varieties but it killed the ones I had.
Yay! I have been using Neem oil all Spring. Hopefully, this keeps them at bay. They have gotten into my lettuce and cauliflower, grrr now they get dosed with Neem Max as well.
Our weeping willow trees had tons of spittle bugs. Plus the willows would weep on their own. Standing under them at this time of the year it felt like it was misting all day long.
Palestinians had all their olive trees burned to the ground by zionists who killed them and took their land funded by US tax dollars, they also did 9/11
I feel like the analogy between Spittlebugs and Mosquitos shouldve been made Both eat your Fluids Both can give a potentially deadly disease to the host
@@UGNAvalon You tell me bro Which, between Malaria and Lyme disease, kills people in the Hundreds Of Thousands every year, and which one kills round about 1/1000th of that number? Mosquitos & Spittlebugs are similar in their potential for Massive impact. That was the point. It's not that deep bro.
I'm glad Hank said it was also called 'Cuckoo Spit', because I was thinking it looked just like it and had been about to ask if that was something different?! 😆
@@sjakierulez Benefit of the doubt. It's pretty narcissistic to think everyone who does things you don't like is a psychopath in the making. By definition it's already unlikely, then farther unlikely that they actually hurt someone.
@iBiana Doubt how is crushing a bug the same thing as torturing a small animal? Just curious, cuz those 2 things seem completely different to me... crushing would be instantaneous death, not torture... and I'm sorry but I can't see killing bugs and killing small animals as being the same thing.
I've been India for a few months ..and saw these spit bubbles for the first time. I kept wondering if it was plant disease..bug related, or even the local toads or frogs with some weird mating practice I didn't know of. Then this video appears today, nice! I've also seen the pictured insect too
Based on some quick googling there have been some attempts at creating genetic phages, and one attempt to sterilize the bugs genetically. It doesn’t seem like anyone has used them commercially however.
Even if we could, it would take a few (insect) generations for it to propagate amongst all members of a species. And that's assuming the modification didn't cause some other issues (some genes don't control only 1 trait/process, or don't act in isolation) that would keep the modified insects from spreading their new genome among the wild population.
@Van The fact science is funded by urgency and not on curiosity or the urgency of people who DON'T CONTROL THE MONEY YOUR GETTING is just pathetic and sad. Your species will never advance fast enough before u reach the great filter if you don't change this methodology. Best of luck smelly apes.
I love the plant representation! Let's talk more about bacterial infections in plants! The tree of life includes our tree families too! How about some plant phylogeny and myth debunking!?
First things first, intentionally prune out certain species detrimental to agriculture and food supply instead of unintentionally pruning out genuses that happen to be in the way of a lot of people.
I have relatives in south Italy and they were hit HARD by the xylella. They had to cut and burn down almost every olive tree they had (my dad's cousin had like 250 trees and some were even more than 200 years old) and most of them changed their culture from olive trees to corn fields. Now most italian olive oil is made from imported olives.
I've had this on my rosemary plant constantly and didn't realise this was what was happening, Only thing I don't get is nothing bad seems to happen to it. Ive had the plant for 10 years now
Never realized these insects could be so much trouble. The only time I would see them in my garden was when I grew French tarragon( who knew an insect could be so gourmet?) Every leaf axil would have its own frothy mound of spittle, and the tiny bug would be secreted inside of it. I'd hose down the plants with a forceful stream of water, sometimes the bugs returned but eventually they got the hint and went elsewhere.
In the southeastern United States, where I’m from, it’s actually _impossible_ for us to grown European grapes due to the high rate of X. fastidiosa infection through sap-sucking insects. Instead, we have to rely on native grape species that have adapted to resist the bacteria- Vitis labrusca and Muscadinia rotundifolia. These native grapes taste good and are great for wines and jams, but they aren’t great for eating indoors because they have tough, inedible skins and large seeds that, though very rich in nutrients, are usually spit out. Because you have to spit out part of each berry, most people consider them “outdoor eating” grapes. Some work is being done on crossing these native grapes with “indoor eating” European ones (seedless with thin skins) to get resistant European-like varieties, but progress is slow as the hybrid varieties are still somewhat vulnerable to infection. Scientists from the University of Arkansas are also working on producing “indoor eating” varieties of our native grapes, but progress is once again slow.

Reminds me of the Glassy-winged Sharpshooter. I found one in my garden just this week. Here in Sothern California, they are an invasive species that can kill weed crops.
I've seen this "foam" every year here in Scotland in the countryside and always thought it was grasshopper eggs, after a quick look online though it seems as though my dog was getting covered in something much nastier
Woooow!! For the first time ever, the “wild” part of our property full of weeds and wild flowers were FULL of those spit wads. I had no idea what spittle bugs were until I googled it. The spittle bugs seemed to be on every damn stem. And I had no idea they became those annoying little hoppers I’ve found everywhere since. But no worries.....my garden is surrounded by that overgrowth 😭😭 This is bad news. But now I know! Thanks for the education
Ok I subscribed. There was a recent article in North Carolina about don't touch the foam and report if you see the foam. And It just reminded me of the time when I was 6 or 7 when my Parents let me watch the Movie Invasion of The Body Snatchers, and a few weeks later my Dad took me to watch The Movie The Shining, Hahahahahahahaha 😂!!!
I had never seen them in Alaska until this year (lived here 26 years) and they are incredibly abundant this year. With climate change, Alaska has been extremely rainy and gloomy this year and I wonder if that has anything to do with it.
I suspect there may be a host plant this doesn't kill, or else it will burn itself out. The xylella fastidiosa is also the cause of Oleander Blight in California, but delivered through different insects, the glassy winged sharpshooter and the blue-green sharpshooter. These bugs are also foreign invaders to southern CA as I recall.
*OH OH OH* When I was in 6th Grade, I found these foam like things on the leaves of plants near our school. I took one and brought it to our room but someone squished it sadly.
The thing with olive trees in Salento is, that the cause for the death of the trees is not so easy to determine. There is also politics and money involved and the damage from the bacteria might actually not be the real reason for the destruction of the huge areas with old trees, as i learned from an article by journalist Petra Reski. There is also research on this topic by Margherita Ciervo of the University of Foggia. She has even Videos on RUclips about the olive quick decline syndrome (OQDS).
Always enjoy your educational episodes. Have your tackled the Chinese Lantern Fly? Our area is covered with the pretty, but troublesome buggers. (Also a note to you: enjoyed your books)
I wonder if that's what causes those red spots on a lot of plants, since the anti-fungal spray didn't seem to be making much of a dent in it? (Went with the anti-fungal stuff, since most quick guides on plant disease seem to show that as some symptom of a fungus. But perhaps some other things can produce similar symptoms?)
We always called tthat frog spit because it would mostly be on plants in our meadow that had a river running through it... If my mother had known this info she would have worried herself into an early grave.
I thought of fastidious; wiktionary says "From Latin fastīdiōsus (“passive: that feels disgust, disdainful, scornful, fastidious; active: that causes disgust, disgusting, loathsome”), from fastīdium (“a loathing, aversion, disgust, niceness of taste, daintiness, etc.”)"
It would be interesting to research why olive groves that have been in existence for a very long time have suddenly succumbed to this bacterial infection.
Why is it that in the Beirut explosion every camera can hear and feel the explosion long before the shock wave hits? What is traveling faster than sound through the air and ground?
I have two bugs that invade my house from my neighbor and they laid eggs in my fingers and they keep feeling me through the full of fluid and they're leaving their big white little things around my house and I can't find any information on the internet
Here in Spittleton we collect cuckoo spit from our coca plantation for the now world famous Spittle Cola and Spittle Tea.. No cuckoos are harmed in the making - although our Old Cuckoo Pie is a favourite with us local.
We should use pesticides to get rid of the spittle bugs all together which would be a lot less expensive since you can use petroleum to make it, and petroleum is abundant.
What would happen if we keep on heating water vapour to ( infinite^n )°C , ie. Such a high temperature which can't be imagined or measured , then can it give rise to a new state of matter of water?
can't we develop some kind of antibiotik against the bacteria? so that vou would only have to inject it into the plants or have them consume it via their roots or smth?
1st thing I love the show. 2nd can you help us out with something? I live in indiana and we've been having really bad storms and last night we had a hollow tree that was really huge fall down it looked perfectly healthy but it was hollow I wonder if a bug or something made it hollow because we think there are more and we want to stop it Edit:It's so big around 3 to 5 people are needed in order to hug it so its probably a few hundred years old
We need many thousands of bat and bird houses put up in and around orchards and farms. The science thus far suggests they are prey to mainly birds and wasps, but bat and bird houses are good for general insect control. Sparrows can eat the spittlebugs and bats can eat mosquitoes.
@@Tymeshifter Bats are near-harmless as long as you're not messing with them. Covid19 is only an issue because China captured bats and GMO'd the heck out of an otherwise benign flu.
Some preventative information would have been nice. For instance, will insecticidal soap keep them off, or is a systemic insecticide effective? Inquiring minds want to know.

I thought of fastidious; wiktionary says "From Latin fastīdiōsus (“passive: that feels disgust, disdainful, scornful, fastidious; active: that causes disgust, disgusting, loathsome”), from fastīdium (“a loathing, aversion, disgust, niceness of taste, daintiness, etc.”)"
It's the same in Italian
Ugh I do really love learning about insects but I hate them at the same time. So creepy and efficient 😭😭😭
It would be interesting to research why olive groves that have been in existence for a very long time have suddenly succumbed to this bacterial infection.
Probably global warming
Spittlebug. Kinda sounds like a cute kids' cartoon show/character.
Why is it that in the Beirut explosion every camera can hear and feel the explosion long before the shock wave hits? What is traveling faster than sound through the air and ground?
Now i know why my field olive oli production declined heavily from the last 5 years
SciShow: Its not bird spit its bug pee let us be clear
Also SciShow: Beware the Bug Spit!!
Sci-show: That would be like you eating 19 tonnes of food a day
Me: you don't know me!
Xylexa fastidiosa? Well it's a really accurate name, this bacteria is indeed fastidiosa
How they breathe in that bubbly cockoon?
I have two bugs that invade my house from my neighbor and they laid eggs in my fingers and they keep feeling me through the full of fluid and they're leaving their big white little things around my house and I can't find any information on the internet
Here in Spittleton we collect cuckoo spit from our coca plantation for the now world famous Spittle Cola and Spittle Tea.. No cuckoos are harmed in the making - although our Old Cuckoo Pie is a favourite with us local.
We should use pesticides to get rid of the spittle bugs all together which would be a lot less expensive since you can use petroleum to make it, and petroleum is abundant.
So we don’t know what eats the bugs or eats the Bacteria or which Bacterial Phages we can use on them?
What would happen if we keep on heating water vapour to ( infinite^n )°C , ie. Such a high temperature which can't be imagined or measured , then can it give rise to a new state of matter of water?
4:15 This tree looks a bit like hands.
Hermione: It's not fastidiosuh. It's fastee-dee-OWW-sa.
Lol good to know that It was bug pee and not bug spit that I might have been allergic to as a kid
can't we develop some kind of antibiotik against the bacteria? so that vou would only have to inject it into the plants or have them consume it via their roots or smth?
"It's not birds spit, it's bugs spit" it's gross either way 🤣
2 questions.
Do they know why the bacteria can only infect certain species?
And got a link to a list of all the species they can infect?
Am sure someone recently said you could eat this stuff and it tasted sweet. They didn't mention it was spittlebug pee
1st thing I love the show. 2nd can you help us out with something? I live in indiana and we've been having really bad storms and last night we had a hollow tree that was really huge fall down it looked perfectly healthy but it was hollow I wonder if a bug or something made it hollow because we think there are more and we want to stop it
Edit:It's so big around 3 to 5 people are needed in order to hug it so its probably a few hundred years old
We need many thousands of bat and bird houses put up in and around orchards and farms. The science thus far suggests they are prey to mainly birds and wasps, but bat and bird houses are good for general insect control. Sparrows can eat the spittlebugs and bats can eat mosquitoes.
No bat house please! Bats are notorious carriers of coronavirus.
@@Tymeshifter Bats are near-harmless as long as you're not messing with them. Covid19 is only an issue because China captured bats and GMO'd the heck out of an otherwise benign flu.
Yay noted! Another bacterium for my story (and a Harry Potter fanfic too!) Love SciShow Bio~!!
"Mosses and a few others" I want to be those now!
You were off camera when you said the number "One million" but I would like to think that you had your pinky up to your face Dana Carvey like.
Some preventative information would have been nice. For instance, will insecticidal soap keep them off, or is a systemic insecticide effective? Inquiring minds want to know.
Does it hurt to use plants that have spittle on them for medicinal purposes?
Why is it difficult to find or create antibiotics for plants?
People start endlessly spraying pesticide again. Nice one guys
Fastidiosa is the famle version of "Annoying" in spanish 😂
"Yes, I know how to take care of plants" then later
hogwarts spell? come on guys you know we don't talk about that anymore... and you know why
I knew my olives tasted weird lately.
