How mites can save trees from bark beetle outbreaks

  • You probably wouldn’t know it, but mites may be used as a biological weapon. But it’s not about warfare, it’s about saving trees in native forests, especially pine trees in Siberia and North America.
    Scientists say climate change has made normally harmless bark beetles as dangerous for pine forests as wildfires. According to them, global warming made pine trees across the U.S., making them more vulnerable.
    The largest bark beetle outbreak in Northern America lasted for nearly 20 years before slightly slowing down - simply because there were no trees left. Russia’s Siberian forests face a similar threat from a different pine beetle species - an invasive species that originated in China and Japan.
    The insect-damaged trees are of no use and can only be cut and burnt, so it is essential to find a way to prevent such outbreaks in the future.
    Scientists from Tyumen University have come up with a solution. They want to use mites that coexist with bark beetles as a sort of biological "weapon" - to save trees and stop forest dieback.

    If you would like to learn more about bark beetles that invaded Siberia, watch the documentary 'Polygraphus proximus' by Ivan Kerchev (tvclip.biz/video/tgDs_jcxA9U/video.html). Kind regards to Ivan for sharing exclusive footage for this video that was produced together with University of Tyumen (www.utmn.ru/en/)

      RUSSIA BEYOND Yes, more Anna videos. Can we also get more Russian history videos narrated by Anna?

    In main country, Croatia we have same problem. Problem is solved. How? We didn't do apsolutly nothing. Nature take care obout selve. Scientist just make more demage

      Zeljko Mikulicic I would agree with you, but the thing is that invasive species do not stop until they kill/eat all they can. These bugs not always have natural enemies, esp on new territories

      @RUSSIA BEYOND and forest will grow again. It's not ekological problem. It's economic problem. Wood industry's stay without any materials too work. Anyway this bug if is spread to much he finds enemy who reduce his number. Nature always balance her self. Problem is in science who doesn't allow that happen.

      Zeljko Mikulicic Sometimes this approach does work. But how vast are pine forests in Croatia? In Siberia and North America if you do nothing, you’ll have millions of sq km of forests lost

    According to Supreme Russian Priest, Russians do not need universities and research facilities as any knowledge tends to water down the very essence of the spiritual binders comprised of religion, deference, illiteracy, and poverty. Universities are satan's concept! All Russians need are churches and temples. The more -- the better!

    Оказывается, площадь лесов в России постоянно растёт. И за последние 20 лет выросла на 80 000 000 Га.

    I've heard of this problem before but I've never heard of a possible solution until now so kudos. But is it true that the greatest threat to the Siberian Forrest is not Beatles but the Russian government selling it to China?

      @Глеб Федоров I see.

      You can see the damage on 2:23. In some areas nearly all pine trees are dead because of bark beetles. This also increases danger of more intensive wildfires. This kind of infestation may be compared to locust outbreaks

    • Глеб Федоров

      Well, the two biggest threats are wildfires and insect infestation. Wood is both smuggled and sold officially to China , but it can hardly be compared to these two problems in scale
