Every year, invasive pests cause billions of dollars of damage to California agricultural systems and natural areas. These pests can be weeds, plant pathogens, insects, vertebrates, shellfish and other aquatic species. There are many invasive species of concern in our state including yellow starthistle, brown marmorated stink bug, and Asian Citrus Psyllid. Additionally, agencies such as the California Department of Food and Agriculture monitor the status of potential pests that may be introduced to California and become invasive. Some examples are the Asian Giant Hornet and the Spotted Lanternfly.
