The Asian citrus psyllid is a pest of citrus and close relatives of citrus. The pest damages plants directly through its feeding activities. New shoot growth that is heavily infested with psyllids does not expand and develop normally and is more susceptible to breaking off. While direct damage is serious, there is even greater concern that the psyllid is an efficient vector of the bacterium that causes the economically devastating disease citrus greening, or Huanglongbing.
For more information, see the Asian citrus psyllid and Huanlongbing links.
