Citrus Pest & Disease Prevention Program Update

National Invasive Species Awareness Week

National Invasive Species Awareness Week is Feb. 27 – March 3, 2017. The week raises awareness about how to prevent the introduction and spread of invasive species, which the United States Department of Agriculture defines as:

  • 1) non-native (or alien) to the ecosystem under consideration and
  • 2) whose introduction causes or is likely to cause economic or environmental harm or harm to human health.

As their names indicate, the Asian citrus psyllid and Huanglongbing are not native to the United States. The pest and disease were first discovered in Asia in the 1800s. Globalization and the movement of citrus plants from one place to another have spread this pest and devastating disease. The psyllid has been found throughout the state of California, and the disease has been found in Los Angeles County.

We must all work together to prevent the spread of Asian citrus psyllid and Huanglongbing. Do not transport citrus plants, budwood or plant material like leaves out of your area, and only buy your citrus plants from local, reputable sources.
