These Mites Rain Down To Save Your Strawberries | Deep Look

- Two tiny mites duke it out on strawberry plants throughout California. One is a spider mite that sucks the juices out of the delicious crop and destroys it. The other, persimilis, is a crafty predator that growers drop by the thousands from high-tech drones to protect their fields.

DEEP LOOK is an ultra-HD (4K) short video series created by KQED San Francisco and presented by PBS Digital Studios. See the unseen at the very edge of our visible world. Explore big scientific mysteries by going incredibly small.
Individual spider mites are barely visible, about the size of a grain of salt, but together they cause huge damage to crops around the world. They suck sap from the leaves and stems of crops and houseplants, leaving yellow or dry rusty leaves and tangles of fine silk.
Farmers can use pesticides to knock them back, but spider mites quickly develop resistance, making them particularly stubborn pests.
So many farmers turn to biological control agents. One of the most popular is another type of mite commonly called persimilis. This predatory mite hunts down spider mites and their eggs.
But spreading the tiny hunters over vast agricultural fields is a challenge, so some growers are turning to companies like Parabug to disperse the predators by air using drones.
Now, entomologist Christian Nansen and engineer Zhaodan Kong at UC Davis are looking at ways to automate this entire process of crop protection. They’re developing a strategy using drones armed with special cameras to detect changes in the way sunlight bounces off plants' leaves.
Software using machine learning algorithms would then read the subtle changes in the leaves' reflectance and come up with a diagnosis about what was causing the stress. If the system suspects a spider mite infestation it could then summon a second drone, packed with predatory mites. The team is working on developing software to accurately drop the predators right on the trouble areas.
“The idea is that these natural predators are like tiny paratroopers coming in on the drones,” said Nansen, “with a special eye in the sky that sees exactly where they need to go.”
--- What are spider mites?
Spider mites are not insects. They're arachnids, more closely related to spiders and ticks.
--- How do I get rid of spider mites?
One of the best ways to get rid of spider mites on houseplants and garden crops is to spray the plant with water to knock the mites off. There are pesticides that will kill them, but spider mites have a knack for becoming resistant. Oils are also used to smother the mites. Biological control agents like predatory mites can be particularly effective.

"Eat the vegetarians" said Persimilis

_eat the herbivores_
I'd probably feel the same way about human vegetarians who ate the last strawberry...

How about we modify the genetics of the strawberry to make them produce persimilis as well?
I am here eating my strawberries knowing that sacrifices were made for them to reach my house safely. RESPECT to the mites. 💗

That's way better than developing stronger pesticides.

I love the fact that, as times go by, farmers find ecological, more natural ways to deal with pests and such problems. Like those guys in Thailand that use ducks to clear pests from rice paddies.
All mites lived in harmony...
Until the fire mites attacked
Earth, Water, Fire, Air.
A long time ago, the four mites lived in harmony.
But everything changed when mites started falling from the sky to protect strawberries
Air teamed up with fire

I used to have a small strawberry garden in my back yard and I remember seeing these bugs crawling all over them and my plants eventually died. Now I know who the culprit was and how to defeat them.

Lady bugs also eat spider mites. And the red mites that you find under rocks in spring and autumn are also predators, they do the same thing.
Wow, I love this channel. Super informative and I love how they give closeups and explain whats happening.

Of course. What else did you expect from deep look?
They always do that
Really informative*
@@stancexpunks does it matter
@@aarontheperson6867 He was just saying.
Your vids are amazing and have teached me some things I didn't even know like how strawberries are vulnerable to many pests but from a type of mite that they use on the strawberries makes the pests not ruin the strawberries. I have to say very good videos, keep it up :D
The shots are sooo detailed! 🤯Together with the high-quality digital models 🤩 it was a pleasure to watch this 🤗
God bless the Persimilises, their sacrifices will never be in vain.

i kid you not it mite actually work
My mom grows strawberries too, no wonder she keeps these persimillis. I always think that they are bad mites so I usually try to kill them but of course my mom keeps me from killing them. Thank you for explaining, now I know what they are use for.
Strawberry farmers be like :" I love the smell of Drones and Persimilis in the mornings...Smells like..victory!"
Entomologist here! I actually work with twospotted spider mites and persimilis on my research project! Persimilis are widely used in strawberries here in Florida as well and Parabug operates down here too. Great footage, love seeing mites get some recognition!
Don't Entomologists study insects? I thought arachnids had their own discipline (Arachnology). Or is it like a Zoology vs. Ornithology situation?
@@gingermcgingin1733 Technically acarology is correct, the study of mites and ticks. But many lesser studied arthropod taxa end up getting lumped in with entomology like acari, myriapods, nematodes, etc. I do study insects too though.
@@joemontemayor2917 neat, thanks
Do those little red spider mites eat dust mites as well? I'll sometimes see them in carpets but the people living there have absolutely no symptom of bite so they're obviously not feeding on people.
@@thanhavictus Persimilis are specialized at feeding on spider mites only.
Imagine the feeling when the angriest redarmy is sent after you...
East germany has a pretty good idea of how that feels :D
omg you play the sims

I really love laura talk about those micro things!
I haven’t watched these videos in so long and im gonna start watching them again!
Imagine walking underneath one of those drones by accident while it was spraying dozens of persimilis
Rip
More like tens of thousands.
You'll only be in danger if you release pheromones
My only thought was a farmer spreading their arms to the mite rain while "It's raining men" plays... I gotta get more sleep.
oh shi-
Persimliils also like to eat mite eggs:

Props to Deep Look for including the part where they started eating the spider mites
When the Emperor of Man heard of the Two Spotted Spider Mites destroying Terra's holy strawberry fields, he simply said, "Send the Persimilis Marines".

Always amazing to be reminded that plants communicate as well. We often forget they are living creatures, just like us!
Who would've known that a close-up of a strawberry looks like skin with very clogged pores.
@Dexhead But true...
I've never been so glad to see mites.
This Channel is pure Gold!
Oh gosh, this is my first time hearing about carnivorous mites. Seems innovatory.
There are quite a few species of predatory mite :) one of many biocontrol options.

try tracking down red clover mites, they do the exact same thing
i love how the information was good and the voice is a perfect story teller
Great information I want to scrub my strawberries even more now!
1:29 The introduction, I replay all the time.
Gives a whole new perspective for "Death from Above"
Farmers: Hey persimilis come over we have all the mites you can eat!
Persimilis : We ate them all, got anything else?
