A field of grapes, sans stink bugs.
The brown marmorated stink bug is a growing problems. Since the Asian insect came to the United States in the late 1990’s, the bugs have spread like wildfire. Now, those bugs are hitting us where it hurts: the booze! Asian brown marmorated stink bugs are attacking wineries across the US. All it takes are 10 crushed stink bugs to permanently alter the flavor of a full ton of grapes. That means, wine is very easily spoiled by the Asian brown marmorated stink bug, which has no natural predators in the United States due to being an invasive species.
So, in order to rid the grapes of stink bugs, vineyard workers have to remove the bugs, by hand, from the bunches of grapes. Given the size of the stink bug problem in wine-making states like Virginia, Oregon, California, and Washington, you can imagine just how much time it takes for workers to pick these annoying bugs off and toss them aside (or squash them).
