extension

As extension entomologists, we regularly give presentations, write articles, develop online resources, or otherwise consult on issues related to arthropod invasions and vector-borne plant disease. Topics include: sharpshooter and Pierce's disease biology and management, Asian citrus psyllid and huanglongbing biology and management, invasive species risk assessment, and the effectiveness of regulatory programs targeting invasive arthropods and plant disease. Below are additional details for a few of our extension priorities, which largely track the major research themes in the lab. A more complete list of extension publications and other resources can be found here

Pierce's disease epidemiology & management. PD is a fatal disease of grapevines caused by Xylella fastidiosa, which is transmitted by native and invasive leafhoppers, such as the glassy-winged sharpshooter (Homalodisca vitripennis, GWSS).
The following presentations provide an overview of PD epidemiology and management, vector control for PD and over grapevine diseases, and the significance of overwinter recovery. We also maintain a blog that captures recent GWSS monitoring results and other information for Southern California grapegrowers

Asian citrus psyllid & huanglongbing. The invasive Asian citrus psyllid (Diaphorina citri; ACP), a vector of a bacterium associated with huanglongbing disease, has emerged as one of the primary threats to citrus worldwide. Our extension efforts focus on understanding the factors contributing to ACP invasion in California, management in residential areas, and limiting impacts to nursery citrus

Regulatory entomology. Other extension efforts relate to the analysis of invasive species introduction and spread to help local, state, and federal regulatory agencies responses. This includes 1) risk assessment of invasive pests such as European grapevine moth (Lobesia botrana), vine mealybug (Planococcus ficus), and ACP, and 2) analysis of the effectiveness of programs attempting to mitigate the impact of invasive pests, such as ACP in residential citrus and GWSS in nurseries
