Overuse of Bioengineered Corn Gives Rise To Resistant Pests
An anonymous reader writes "Though warned by scientists that overuse of a variety of corn engineered to be toxic to corn rootworms would eventually breed rootworms with resistance to its engineered toxicity, the agricultural industry went ahead and overused the corn anyway with little EPA intervention. The corn was planted in 1996. The first reports of rootworm resistance were officially documented in 2011, though agricultural scientists weren't allowed by seed companies to study the engineered corn until 2010. Now, a recent study has clearly shown how the rootworms have successfully adapted to the engineered corn. The corn's continued over-use is predicted, given current trends, and as resistance eventually spreads to the whole rootworm population, farmers will be forced to start using pesticides once more, thus negating the economic benefits of the engineered corn. 'Rootworm resistance was expected from the outset, but the Bt seed industry, seeking to maximize short-term profits, ignored outside scientists.'"

That's how life works doesn't it? Pest attacks plant. Plant evolves defense. Pest finds a way bypass defense.
I wonder when will we learn that fighting the Nature is not the best path to survival.
""little EPA intervention""
There to busy going after everyone else.. The article itself isn't surprising, and the industry will be on the defensive with GM crops, and I'm waiting to see resistant weeds, and insects, as they are exposed to stronger, or more powerful insecticides/pesticides. Not that their more toxic, but I would expect to see the same resistance.
Who coulda known?
Are those bioengineers creationists who didn't think nature would adapt to those new genes? crazy.
1. Bug eats corn
2. Engineers update corn to 2.0 to withstand bug
3. Bugreports come in implying corn 2.0 still has bugs
4. Engineers should bugfix corn again, it's called 'progress'
is this: agricultural scientists weren't allowed by seed companies to study the engineered corn until 2010.
surely with the help of our corrupt lawmakers.
How in the hell can scientists NOT be allowed to study IN DETAIL, and from the get-go, something as fundamentally groundbreaking and new as genetic engineering applied on a planet-wide scale for the first time ever in the history of life itself?
We need a revolution to overthrow the current government structures the world over, and sooner rather than later, if only because some day, Something Bad[tm] will happen that'll cause genuine harm to humanity.
"A door is what a dog is perpetually on the wrong side of" - Ogden Nash
We need to start outsourcing our problems to Nature. How about we genetically engineer corn which can only be eaten by organisms which excrete efficient batteries, BitCoins and flying cars?
And this is what happens when decision are made by money greed capitalists. If scientist would lead the world, it would look quite a bit different.
Why doesn't slashdot stop its overuse of bioengineered corn?
Such counter-revolutionary feeling is only happening due to yours being a matter of breaking away from a foreign power that was very busy at the time and so didn't come in to wash the streets of New York with blood. You clearly cannot imagine the price. Take a look at revolutions against strong and established governments based where the revolution has happened and you'll get a good idea of the cost. Take a look at the outcomes of those and compare it to what George Washington's revolution gave you.
Do you really think you will get something better and what is wrong with George Washington's ideas in the first place that another revolution is required to replace them?
Why do you think it will turn out better than what Egypt is dealing with now?
"but the Bt seed industry, seeking to maximize short-term profits"

Okay, I can be pretty dense when it comes to reading between the lines, but even I notice a heavy dose of agenda in this summary. It's a good thing the anti-GMO folks have a crystal ball to see the future clearly.
I guess we need our daily dose of propaganda though.

Years ago (10 years or more)? There was a study about the arms race in agricultural pest control. The subject of this study was a genetically engineered crop that made its own poison, but that was not really relevant to the outcome of the study. Traditional spraying would have the same effect.
It was discovered that poison did not only fight pests, it also helps pests. The non-resistant pest bugs were killed, but the resistant pest bugs were given a predator-free environment. This was important, because the poison resistance often comes with lower chances of survival in non-poisoned environments. For example, one poison had an impact on the nerve system, paralysing non-resistant bugs. Resistant bugs had a nerve system that worked much slower, so they would be a "sitting duck" in a natural environment.
the study showed that if a certain portion of the land (recommended was 15% to 20%, which sound like a lot, but is peanuts compared to the 60% loss often found due to resistant pests) was planted with non-poisoned crops, the whole arms race could actually be stopped. The bugs would move between plants, and if they came on a poisoned plant they would be attacked by the poison, and if they came on a natural plant, they would be attacked by their natural predators.

Phytophthora infestans A1 type created famine in 1845 in Ireland and Flanders.
Blight was largely under control in 20th century until the Oömycete got the chance to sexually reproduce with the A2 type imported from latin America to Europe around the 1980's.
Potatoes are largely from the "bintje" variety because consumer wants so. And potatoes are "cloned" by planting tubers from previous harvest.
I went to a seminar about a year ago at Clemson U. The presenter went over all of the protocols that farmers are supposed to follow, which included growing non-modified corn in a certain proportion of their acreage. This was to prevent this very thing happening. The idea is that pests thrive in the non-modified crop and spawn non-resistant offspring, and since their numbers are much larger than the bugs in the modified crop, they pollute the resistant DNA and they don't develop herd immunity to the modified corn.
He basically said that the pests are becoming resistant because farmers are not following the protocol, because the non-modified crops basically get obliterated as a honeypot for pests to thrive and multiply, and the farmers don't make any money off of that acreage.
So, don't blame the corn. Blame big agro for failing to follow the rules in the name of greed and profit.
...as long as it's only in the hands of greedy corps.
Because it's about furthering their interests, which most of the time don't align with mine.
So there was a switch to rootworm resistant corn, which I'd assume came with a declining use of pesticide. If the rootworms overcame resistance to the resistant corn, does this mean they may have lost some of their resistance to the pesticide?
Or are these resistances somehow retained or overlapping so that we have rootworms with high resistance to both?
Other than the nasty concept of pesticide use generally, it sounds like maybe this would allow for a switch back to pesticides which the rootworms may have lost resistance to.
Or will my cynicism be correct, that farmers will use both the resistant seed AND pesticide and develop a super-rootworm with strong resistance to both?
evolution isn't real, right? adaptation to environmental stresses just a theory...
tell that to these farmers.
never bring a twinkie to a food fight.
News at 11.
Come on. really? nobody expected this?
This is why you are supposed to ROTATE pesticides not using the same thing over and over and over.
DDT has been out of use so long that I bet it is highly effective if they bring it back into use, but this time using it sparingly not dousing the entire countryside in thousands of gallons of it.
Do not look at laser with remaining good eye.
Yummy.
I am very small, utmostly microscopic.
or two, it was well worth the experiment, at least to the CEO and shareholders. The CEO got his bonus and the shareholders got their bump in the price and that's all that matters.
When the CEO lays off all the genetic engineers because of this "problem" the shareholders will reward him with another bonus for being so proactive.
I don't know why you guys are getting so upset. It says right there in the Bible that God gave us all the plants and animals to do with as we see fit.
Which is why I tried pointing out to the above poster that a revolution has already been won for him - IMHO tweaking the current situation instead of throwing it all away to be a dictatorship or whatever is frankly somewhat more sane.
"1996. The first reports of root worm resistance were officially documented in 2011"
So we got 15 years of pesticide-free corn? And the downside is we have to return to what we used to do, until we get another variety?
If it's 15 years for that one too, I suspect we can out engineer the bugs continually.
It is going to cost big business to retool factories to generate less CO2 emissions. They continue to do everything to maximize short term profits, without looking at the long term harm.
If they had their "no government intrusion" the way they want it, they'd still dumping waste in our waterways, and the major California cities would never have any smog-free days.
Seed with limited number of generation, simply kick themselves out of any gene pool which has no such limitation.

So your point is what? Do not use the corn and the root worm thrives? So what is the point then when the root worm overcomes the
modified corn's resistance and starts a come back? We had 15 years of extra corn productivity that we would not have had.
And the down side of this? None. Other than some fool who believes that that a short-term victory is somehow worse than no victory
over pests.
Why don't you people at Slashdot use your brains before putting this crap out?
Crapdot. Where the undereducated, hormone-challenged wanker comes to ejaculate worthless words from their never closed mouths.
Just pour more and stronger pesticides on it. I mean why would it be dangerous somehow? It's just on the outside of the crops and in the soil, it's not like inside the parts you eat, right.
There is noting weird and baleful about GM species that causes them to behave differently from non-GMOs in the environment, including how other species co-evolve in response to them. There was an early belief that transfer of genes between species was special manmade magic, until it was found that this happens in nature too: http://davesgarden.com/guides/...
Genetic engineering is nothing but a precisely targeted way of accomplishing changes that used to take generations of cross-breeding and culling.
If you try to hide from a life form or kill a life form using a biological pathway, you will eventually generate a better life form that gets around your efforts.
Someone explain to me again how GMO crops are the only possible way human beings are going to solve all our agriculture problems, and people opposed to them are Luddites? Did they not think that natural selection more or less negates any gains reached through GM within a few generations?
It doesn't exempt itself from evolution. So the question we need to be asking ourselves is, WHEN pests evolve to thwart GMO "innovations" what might those pests be able to DO how BAD will THAT be and how are we going to deal with it and how quickly can we react what happens to the food supply if we CAN'T?
This sounds like BS to me. Why would there be any more resistance issues with engineered corn than with pesticides?
This is great news! Maybe my bees will develop a resistance to the crops and stop dying off when they come back from the corn and soy fields.
From the Abstract of TF Paper.
"These results illustrate that Bt crops producing less than a high dose of toxin against target pests may select for resistance rapidly; consequently, current approaches for managing Bt resistance should be reexamined."
Make of that what you will.
More on this unexpected development later.
Either in "Stand on Sansibar" or "Sheep looking up" I think the latter one. Well at his time it was considered SF. However it was plausible. And I'm not surprised that it indeed worked. Now lets wait for the worms to really mutate and become nasty :D
Cost free eBook I read (by iBook/Kobo/Amazon/ObookO/Gutenberg etc.): "The Green Odyssey" by Philip Jose Farmer.
Of all the real issues with the GM industry, causing cancer isn't one of them. Screaming "cancer" is what separates the morons from the people who actually know what they're talking about in the debate.
There never will be a perfect government because governments are run & selected by humans, and humans have a lot of character flaws. If you want an AI government, then it could slip into a totalitarian government without humans noticing and we'd be imprisoned or discarded.
Better to suck 30% than suck 100%.
I smell unrealistic idealism: "because it's not perfect, bulldoze it down and start over."
Table-ized A.I.
This article is just plain stupid. Pests will eventually develop resistance to anything. You can't turn off evolution! To assume that GMO plants somehow avoid this inevitability is just a strawman that can then be used to 'prove' how awful GMO plants and their associated producers are. If there is a villain it is mono-culture. But mono-culture is just another risk/reward tradeoff. Mono-culture makes farming much more economical but gives evolution a much larger population of genetically similar individuals to operate on.
No. GMOs do not and would never exist in nature. Animal genes and plant genes don't mix in nature. Pigs and humans don't mix. A virus doesn't splice its way into your genetic code and become part of you and part of your children.
People are extremely ignorant about what GMOs actually are, even here. It's truly sad.
The way I read it, they came out with this new strain of corn that prevented the pest from infesting it. The pest adapted. So we are no worse than before, but no better than before. What is the horrible crime that has been committed? The vendors of the new strain off corn just put themselves out of business by overselling.
I can see why the scientists who came up with the 'fix' would have bruised egos, from thinking their 'breakthrough' hasn't saved humanity, but butthurt scientists are nothing new. Humanity often routes around the scientists' miraculous fixes, cuz human populations are not scientifically controllable. Scientists who want complete control should stick to populations of white mice.
Pest Resistance is a journey not a destination
The only thing that is sustainable is change
As far as I'm aware, the seeds you buy with these traits come with a "best practices" information sheet that tells you exactly this kind of shit. That farmers still ignore that advice, even knowing what the outcome will be, can hardly be blamed on the biotech companies. After all, the farmers are the ones ultimately putting the seed in the ground. But hey, anything to bitch about Monsanto and the rest, right?

Be the darkness that allows the light to shine.
You are surprisingly ignorant...
Since, YES, Horizontal transfer does indeed happen, and is widely documented. In fact, it happens A WHOLE LOT.
Yes, porcine and human genes do mix, using viral vectors and other methods.
Yes, Viruses DO INDEED permanently integrate into human and animal genomes. (You DO know that the genes responsible for placental implantation in many placental mammals comes from precisely this source, right? You DO know about the porcine endemic retrovirus, and other such things?)
The argument shouldnt be that "Those things dont happen in nature", because that is straight up wrong. The argument should be that "Natural occurence of this is very narrow in scope, and only persists when there is a profound advantage boost, and then only takes root after a considerable incubation period, and that this behavior has no direct analog with the unnatural section processes used by humans in agricultural settings.
Not this one. Not any honest ones.
The problem with bt GMO corn is that the pesticide is present in the corn field 24 hours a day, 7 days a week. Prudent use of a pesticide dictates that you use the pesticide as infrequently and as sparingly as possible. If you use it all the time, the insects you are trying to control will develop a resistance to it. But with a GMO plant which is producing the toxin continuously, you are providing the perfect environment for the insect to develop a resistance to it. Sadly, bt toxin is a pesticide that many organic farmers depend on. Since bt toxin is a naturally occurring toxin, it is allowed in organic farming. But, due to GMO crops like bt corn, organic farmers are going to lose a useful, natural pesticide as insects develop resistance to it because they are exposed to it all the time. But companies like Monsato will never be held liable for selling a product that is causing immense harm to organic farmers.
Greed and incompetence combined is just e vil.
... the patent on this particular strain of corn has just run out.
"A Ponzi scheme is a fraudulent investment operation where the operator, an individual or organization, pays returns to its investors from new capital paid to the operators by new investors, rather than from profit earned by the operator." --Wikipedia Or, in the case of engineered corn, the engineering generates its own demand. See also addiction. There is no sustainable value, only the false image of value, money, and only to one party, the engineer.
Nature finds a way.
"Uh, what's your point?"

Star Trek transporters are just 3d printers.
There are different versions of genetic modification. Taking a specific gene and transferring it into another organism is not a heck of a lot different from breeding for a trait. In some ways, more predictable since you know what protein you're going to produce, whereas breeding can have all sorts of odd pleiotropic effects, selection for major things like paedomorphism, etc.
The other kind of genetic modification is the "shotgun" method; chop the total DNA of these insecticidal bacteria into manageable pieces, mix it up with plant embryos, grow a zillion of them up and grab any which have incorporated the insecticides. And who knows what else.....
Star Trek transporters are just 3d printers.
people too stupid to know when they've been PR'd into psudo-scientific corporate submission.
But no, we shouldn't have the ability in the US to know what foods contain what so that we can make our own choices, because, like, people will stop buying the shit...
