| 31. | The corn borer damages as much as 10 percent of the European corn crop each year, analysts have said.
|
| 32. | It was tinkered with genetically to build in the pesticide Bacillus thuringiensis, or Bt, that kills the corn borer.
|
| 33. | The remaining 20 percent must be a non-Bt variety-- so that enough of the corn borers can survive and reproduce.
|
| 34. | DIMBOA is also responsible for the relative resistance of immature maize to the European corn borer ( family Crambidae ).
|
| 35. | The corn borer can cost U . S . farmers as much as $ 1 billion annually in lower yields.
|
| 36. | Genetically-modified corn seed fights the corn borer, and a new gene being developed will resist corn rootworm, another destructive pest.
|
| 37. | In 1928, the US Congress recorded that Ottokee Grange No . 273 had resolved to clean up European corn borer.
|
| 38. | This was attributed to European corn borer populations reduced by exposure to Bt corn, leaving fewer to attack conventional corn nearby.
|
| 39. | StarLink has a bacterial gene that allows it to produce Cry9C, a toxin that kills the corn borer, a common pest.
|
| 40. | The corn, given a gene from the Bacillus thuringiensis bacterium, then produced a toxin that killed the European corn borer pest.
