Five of 13 major crop pests have evolved resistance to corn and cotton genetically engineered to make their own insecticide, providing lessons for extending the usefulness of such technologies, University of Arizona researchers said in a study.

The increase in resistance, from one insect species in 2005, was expected because the crops are more widely planted, pests have been exposed to the insecticides for more years and monitoring efforts have improved, according to the study published today in the journal Nature Biotechnology. Some technologies have kept resistance at bay for more than than 15 years while others succumb in as few as two years, the study said.

Very interesting, but for sure not news. Am surprised its only 5.

In an ideal World a law would be passed were NO guns were allowed and all those out there destroyed, trouble is the law makers are not going to take a risk of trying to pass that without making sure they are armed first.

No, nothing really new or surprising.

Can't say it surprises me give them time and they all will become resistant to these crops.

Many weeds have become resistant to roundup.

It makes you wonder if you could place fast breeding insects inside a containment area that changes between two states of atmosphere pressure(a low and high) and have them develop a tolerance for near vacuum conditions in enough generations.

Wow yes ... develop strains of pests that can exist in near vacuum and send them to the Red Planet on the next Rover mission. That way the bugs will be ahead of the game before we start terraforming, planting opium and hemp. So many great things are to be gleaned from GM technology.
