Huanglongbing

One of America's most popular food staples is at war against an insect smaller than an apple seed that is spreading an incurable disease.  The nation's orange industry has taken a more than $4 billion hit as dead trees and useless crops recently sent orange harvests to their lowest in two decades. 
                
The disease is called huanglongbing, also known as citrus greening. Producing oranges too bitter for juice and too misshapen and discolored for fresh fruit, the bacteria leaves farmers little choice but to destroy every one of their sick trees.
The crawling culprit facilitating its spread is the Asian citrus psyllid, a plant juice-sucking bug that can easily become airborne and carry the fatal bacteria that destroys oranges, limes, lemons and grapefruits.

Of greatest concern to the government are a group of non-native ants, beetles, moths and flies, and one giant slug. 

Forest resources in the North Atlantic states are under siege. The Asian longhorn beetle is menacing "recreation and forest resources valued at billions of dollars" and has the potential to destroy "millions of acres of America's treasured hardwoods," according to the APHIS.

Just a thought.
