Citrus Research Board Mapping Site for Asian Citrus Psyllid

Asian citrus psyllid eggs and nymphs.

Welcome to the Citrus Pest & Disease Prevention Program's Interactive Mapping website. The purpose of this site is to provide researchers and stakeholders, including pest control advisers and growers involved in the California citrus industry, with online tools to map and monitor the introduction and distribution of exotic invasive citrus pests and diseases. It also serves as a resource for collaborating citrus researchers, such as regulators and pest management agencies.

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.
