Study: Global warming might help insects in war on plants

When University of Illinois researchers found that soybean plants heavily exposed to carbon dioxide at an open-air lab here suffered more insect damage – and that the insects damaging them lived longer – they wondered what was behind the effects.

The result: a UI study indicating that higher carbon dioxide levels associated with man-made emissions, generally thought to play into climate change and global warming, appear to make plants, soybeans anyway, more susceptible to some insect damage by impairing their chemical defensive systems.
