The pine processionary caterpillar: Conquering Europe | SLICE

- For thousands of years, the pine processionary caterpillar has been slowly but surely marching towards Northern Europe. Devouring the pines, the processionary caterpillar is a great destroyer of the European forests. In the Landes, the damages caused by the processionary caterpillar are so spectacular that one can even follow the animal's tracks. Several research teams are studying the behaviour of this disruptive insect, in the hope of slowing down its expansion.

My dog sniffed one of these today. I put some hand sanitizer on my hand and onto his nose thinking there might be bacterias. 10 minutes later my hand was like being scorched with hot water. Still feel pain after 8 hours. Just found out these are toxic so no alcohol will help. My dog is ok though. No swollen nose, nothing.
I have been digging with my hands under a pine tree...for the next month i had a full body rash 😂😂😂
I had a similar experience and my aunt applied this aloe vera gel from this brand called Curaloe, this was a few years back, I had to go see a doctor anyway but this gel really really helped me cool it down.
@PolAdd22 y wud you do that
These caterpillars are very dangerous because you don't know on which side a pine will fall if it has been attacked. The pine tree compensates dead branches by more branches on the side. But branches are what makes them stable, since their root is only vertical. When they fall, they make a kind of spiral curve that one cannot practically predict. My father knew a timber worker who died under such a pine tree.
one dropped on me ones 15 years ago I still hate those evil creations.
I "loved" the bit about the damaged forest in France. Oh no, we planted one million hectares of pine in a monoculture, what could ever go wrong?
Well, the pines were supposed to maintain the stability and drought of what was a sandy marshland before
As my parents were children, my grandparents considered that processionary caterpillars weren't so huge a problem as long as the winter lasted until the return of the cuckoos... I wonder if there still are cuckoos now.
@@materliliorum I don't think planting pines was a smart idea. Moisture evaporates quickly between the needles that don't create shade, and wind will easily reach the topsoil, so the soil will still be very dry. These pines are very dominant also. It sure looks green with all the drought-lovings bushes growing between the pines, but it's still not fertile.
I think planting native deciduous trees would be a better idea, because of keeping moisture under their crowns, and blocking wind. But they don't grow as fast as the pines so it was probably more about fast production of furniture- and firewood. Pretty sad actually. I actually love to see pine forests getting destroyed, so more native trees and plants can grow. It's a long process but adventually will do good I think.
@@renzovanlaere7926 there are no native deciduous trees to this region, to my knowing. It was originally a poor sandy marsh and it still suffers frequent floods (principally because of iron oxide plates underneath). There are few spots where the sand is darker and gets approximately covered with grass, and where you can grow apple trees, but otherwise even weeds are scarce due to the soil being sand. On other spots you can grow platanes. So I still believe pines are a great idea, and it was even a greater one formerly, when the pines were surrounded by quercus suber, which cannot be set on fire.
@@materliliorum I watched allot of deserts and how to green!. There is always native trees and plants who was belong to the place of environmental degradation!.
My dog almost died from intoxication due to one of these caterpillars. Got to the vet just in time...
Omg...
Yes, I was with friends and their dog in a forest near Jerusalem. We did not know what these nests were. When we got back we looked up what they were and were very glad that we did not see any caterpillars. In the description - poisonous to dogs... I'm that that your dog made it through the ordeal...
People need to plant mixed forests, not just pine
I used to work in pest control from the ground and the air. These are easy to control with the right pesticides. Today bugs are more important than humans. Every pesticide has something negative about it, but if Europe wants to keep its forests they better quickly do something.
This caterpillar can switch to picea abies btw, I saw it at my grandparents'
I left my home because of this insect 😡
When and where do the go thru transformation, & what do they become?
there are thousands on dalmatian islands in the adratic
I notice that the trees in the mountains look relatively healthy even if the caterpillar is around, so it appears it is not a problem in its natural environment. It is only as an invasive species it is a disaster.
amazin ty
Slowly and surely
Save environment
No. These bugs thrive in jungle. No jungle no threat
Wow!
no no no no no no
Very...very hungry babies
Well, thats what you get for monoculture.
Kadaghan ug eras!
