+ - Another Invasionary Species by the USDA?->

Submitted by gpronger
gpronger writes: USDA proposes to use a Spanish wasp for weed control along Mexican-US border. Carrizo Cane, a tall reed that grows along river banks, etc has spread rapidly along the Rio Grande. The height of the reed, and the density that it grows, gives cover to illegal immigrants. The wasp lays it eggs inside the stem, causing the plant to dwarf or die.

The question to ask though, is what other agricultural plants it may go after once released?

Have we ever had a purposeful release of a foreign species that went as planned?
