What kills spotted lanternflies? Researchers making progress in getting invasive bug under control

- Summer is almost here, so it won't be long before we start seeing spotted lanternflies. Ross DiMattei spoke with local researchers on what we can expect this summer.
It's crazy to me that, after 10 years, their solution to address one disastrous species is with another potentially disastrous species.
They're specialists for a reason.. these wasps all are weirdly specific and focus certain hosts.. like tarantula hawks.. hence their name
I think scientist should raise birds and teach them to specifically go after the lanternfly. Birds would do a hell of a job at keeping the lanternfly numbers in check and possibly wipe them out in some areas.
By the time the birds discover them, and they do eat them, most of the damage is already done. Sooty mold can quickly take over a garden destroying plant after plant, all caused by the insects in the tiny nymph stage before birds will find them.
And will we need to bring another species for the wasps?
No because of their life cycle. These parasitoids are solitary wasps, not colony formers like yellow jackets or hornets. As adults they live alone and feed on pollen and nectar as adults. They control pests during the juvenile part of their lifecycle. They lay their eggs in this case the one lays it’s eggs on the eggs of the lantern flies where it hatches and eats the eggs. The one that attacks “adolescents” (nymphal stage) lays its eggs inside the individual with its ovipositor and the eggs a hatch and eat it from the inside.
Like the video says the problem is that they might decide to lay their eggs on a native, non-pest insect.
Biocontrol is our best bet for a lot of things if we can find specialists. I’m so intrigued by the biocontrol for Japanese knotweed. What a vicious plant
@@TheModerateMillenialRight, because that worked out so well in AU with the Cane Toads. It's tantamount to solving a house fire with gasoline. 🤦♂️
@@NinjaRunningWild toads are a generalist. That was a stupid idea.
These controls they are testing are specialists that evolved with the lantern fly. There have been plenty of successful biocontrol since the cane toad. And the testing here in North America is very rigorous and takes place successfully with cooperation from USA and Canada.
Our dragonflies eat them
seems like we need to encourage birds to feed on them
They have done studies to try and encourage birds to eat them and they will as long as they haven’t eaten on their preferred host: the tree of heaven. If they have fed on the tree of heaven they take in the plant photochemicals and don’t taste good so birds won’t eat them. And birds like a dog have a Pavlovian response and they eat it once or twice and doesn’t taste good they will never eat it again.
To help combat that, removing tree of heaven will help prevent them from tasting nasty to birds. 😊
How do you encourage a bird?
@Honeytea237 I'm not a scientist bro I don't know 😭 if bird actually ate em the problem would be solved
@@Honeytea0826 teach might be a better word. But birds are super stimuli based in their memory so if something tastes gross they won’t eat again. If you google it will explain the methodology for encouraging/teaching to eat them
@@rcg224 oh ok thank you for the info. I was wonder why they aren’t already eating them.
We were infested with them in past years in NJ on trees near our house. This year there is nothing. I saw a bunch of nymphs a few miles north of my house at a park months ago, but I’ve only seen one nymph and one adult today, but they were both dead, like they just died naturally. I haven’t seen a living one near me this year like they can’t thrive. It’s quite strange.
maybe the sparrows figured out that they're tasty treats
Their numbers are dwindling because everybody is killing them, but they reproduce so fast you’ll be seeing them again, don’t worry.
People are likely applying a systemic in your immediate area, something like Merit which unfortunately will also kill honeybees if applied on flowering plants. Used on the right plant, it really can control invasive insects.
Completing the food web. What a concept
Flamethrowers and shoes.
We already have local praying mantis, and also birds that figured out that lantern flies are edible.
I can't believe that no birds have figured out these big bright slow flying turds are an OK snack.
I remember in the 80s Japanese Beetles were everywhere, and everyone had traps that would catch them by the bagful. Now I hardly see them? Can't we do something similar?
I think the real question is when the lanternfly season isn’t in effect what do these newly introduced predators eat during that time? Maybe finding another invasive bug species that it can eat during that time would be smart.
I saw one on my porch yesterday, I said to my daughter, they're here! She said what and her bing 30 RAN into my arms and said no no no! I just laughed. 😁
They are covering my house. How do i get rid of them?
Ok, I found this few days ago, still experimenting but it looks like it will work, so far it’s few hours since I put my mixture outside and few lanterns drowned in it! Waiting for more!
Mix 3 cups of water with 3 cups of pine-sol (any amount equally) and 1 cup of sugar. Leave it near the place you spotted the lanterns. Hopefully it will help.
Dawn dish soap mixed with
water can kill them
I'm getting Metroid vibes here. To combat the X parasite, the Chozo created the deadly Metroids.....we are doomed
Remember when they brought those flies to kill fire aunts and they start to kill the bees
Apparently Rachel Bergey does.
Doesn't she have a walmart to loot?
Tree wrapping works best
Next video: What kills Parasitic Wasps?
They already are coast to coast.
They kill more than just grapes!
Wasps sting people also what happens when the wasps kill off the flies and look for something else for dinner
Says in the video that the wasps don't sting. It also says in the video they're testing to see if the wasp would damage other insects besides the lantern flies.
My cat catches and eats like 5 - 10 a day 😂
Rip your cat
They are nasty!
Now all we need is something that will attack the invasive species coming through the southern border 🤣🤣🤣
Dawn and water = 1-3 minutes then dead.
Praying mantis are eating them! So raise all the baby aliens(what I cal praying mantis baby's) we can!
Don’t do it!
You’re talking to one of the guys who probably brought these pests over here in the first place. Let bring in another invasive species to eat the first one. Only to find out that now you two more.
thanks asia... -_- first k pop now this
@@AedanBlackheartAfter Coronavirus & Bubonic plague.
Never a good idea to introduce another non native species.
