Monsanto GM Corn in Peril: Beetle develops Bt-resistance

Nature herself may be the best opponent of genetically modified crops and pesticides. Not only plants, but insects are also developing resistance. The Western rootworm beetle – one of the most serious threats to corn – has developed resistance to Monsanto’s Bt-corn, and entire crops are being lost.

Farmers from several Midwest states began reporting root damage to corn that was specifically engineered with a toxin to kill the rootworm. Iowa State University entomologist Aaron Gassmann recently confirmed that the beetle, Diabrotica virgifera virgifera, has developed resistance to the Bt protein, Cry3Bb1.

Bacillus thuringiensis – Bt – is a bacterium that kills insects. Different proteins are engineered into cotton as well as corn plants.

Two-thirds of all US corn is genetically modified per the USDA, and the bulk of that is Bt-corn. Monsanto has the biggest market share in the US, reporting about 35% in 2009.

In response to the July 2011 study, Monsanto said only the “YieldGard® VT Triple and Genuity® VT Triple PRO™ corn products” are affected.

“It appears he has demonstrated a difference in survival in the lab, but it is too early to tell whether there are implications for growers in the field.”

However, Kansas State researchers summarized the study, indicating that the specimens tested came from fields suffering severe rootworm damage and compared them to those from unaffected fields. In other words, it was a field study.

Resistance developed where the same Bt corn had been grown at least three years in a row. Gassmann found “a significant positive correlation between the number of years Cry3Bb1 maize had been grown in a field and the survival of rootworm populations on Cry3Bb1 maize in bioassays.”

Ag Professional’s Colleen Scherer explains that “the Cry3Bb1 toxin is the major one deployed against rootworms. There is no ‘putting the genie back in the bottle,’ and resistance in these areas is a problem that won’t go away.”

Monsanto urges farmers to try their “stacked” GM products where more than one trait is engineered and to employ integrated pest management (IPM) techniques.

Kind of like getting on a treadmill of ever increasing DNA manipulation and chemicals to maintain monocultures, instead of reverting to time-honored mixed farms that use companion plants (including weeds) for pest control. IPM does not have to include toxic chemicals or genetic manipulation for success. (See, e.g., Sepp Holzer’s Permaculture).

This year, Monsanto launched a “triple-stack” sweet corn which it envisions being sold at Farmers Markets. The FDA’s GMO label ban will certainly help, since most people who buy local are specifically trying to avoid genetically engineered foods.

In line with Monsanto’s goal to enter farmers markets, the Union of Concerned Scientists just came out with a report urging federal financial support in order to create jobs. The report notes that the number of farmers markets has doubled in the past ten years.

But, as we watch the feds target natural producers with raids and product seizure, while leaving Cargill’s 36 million pounds of tainted turkey alone until someone died, we can expect that any federal money put toward farmers markets will be used to support only that produce which is genetically modified, chemically doused and/or irradiated.

  1. Anyone who has access to LINK TV should see the show they are running on Monsanto —-Monsanto is without a doubt on a mission to destroy people —–their mutant frankenstein GMOs are ruining the lives of people in all poor rural areas —-and guess who is behind their getting away with NO real FDA intervention –none other than Bush Senior —-yep, shows him right there —– I used to think Dick Cheney was the most evil man alive, but it maybe Bush –no wonder they are linked together in their plans to destroy mankind and enslave the planet once they have destroyed everyones health…………the NAziz and their concentration camps had nothing on this first family of absolute evil…………..and every scientist who tried to stop it – they lost their jobs and were threatened ——and if they were willing accomplices to the plan —-they got big fat payoffs…………….and if you look at Monsanto —they aren’t even that big of a deal —–sure they’ve made millions off this —but their real purpose was clearly destruction of the public —–confiscating farms and controlling the food market ———–they should all be prosecuted!!!!

  2. Ah, yes! Monsanto! One of the Illuminati front companies, like Coca Cola and PepsiCo. (Is one of these the “flag ship” or do they just sort of network like the secret societies that run the government do?). Just think about it. This is really weird. Here you have a group of geneticists, presumably, scientists, biologists, even, that is, who apparently know absolutely nothing about basic principles of evolution. WHENEVER an environmental threat (toxin, in this case) succeeds in attacking a population of organisms, even if it’s 99% successful, it’s bound to leave some “survivors”! Why did the survivors survive? Because they GENETICALLY lacked receptors which would bind to the toxin. THEN, if the survivors reproduce, and the genetic trait “breeds true” (carries forth into the succeeding generation), then the new generation will be immune to the toxin. We have seen this same phenomenon reproduced time and time again, regardless of the biological stock. It could be MRSA (methycillin resistant staphyllococcus aureus) resistant microbes, or even Monsanto’s very own “Roundup Ready” weedkiller resistant weeds. Genetic modification implies incompetency. The very nature of experimentation means that you don’t know 100% what you’re doing or what all the implications are likely to be. Take Jonas Salk, for example. In an effort to develop a vaccine against polio, he ends up poisoning the entire U.S. population with carcinogenic SV40 virus. Google SV40 and see what you get. If you didn’t get injected directly with this shit in the 1950′s, the virus went along for the ride on your mom’s and dad’s (or grandpa’s and grandma’s) egg and sperm cells.

  3. monsanto(monster satano) was never created to help people or make crop resistent-Their job is to destroy humans health.The rest is money and camouflage.

  4. LEE ENIGMA SAYS:
    AMERICA THIS IS A CORN JOB BY MONSANTO TO KEEP GMO IN THE FOOD CHAIN. AMERICA
    DON’T GET CORNFUSED WIL THESE BUFFALO CHIPS . YOU MY PAY MORE FOR ORGANIC FOODS
    BUT THEY WILL NOT HURT YOUR FAMILY !
    AMERICA IT’S YOUR CALL, DON’T LEY ANYONE THINK FOR YOU AND YOUR FAMILY !

  5. Not good. This isn’t going to hurt just the GM crops. This is going to hurt organic crops as well.

  6. Did anyone else read the genetic designation Cry3Bb1 as “Cry Baby 1″?

  7. Wow, it,s like the way the girms killed the alien invaders in War of the Worlds. Cool!
