F\ig Wax Scale has recently been detected in the environment in the San Diego County. This insect is commonly intercepted at ports of entry, especially on shipments of palms, but has not previously established a reproductive population in California to our knowledge.
Fig wax scale is an A-rated, actionable invasive pest by CDFA, due to its high potential to damage fresh fruit production through lowering yield, increased production costs, disruption of export markets, and vectoring of plant viruses including grape vine leaf-roll virus. It is a polyphagous phloem feeder and a potentially devastating pest of many high-value crops including almond, grape, citrus, pistachio, avocado, cotton,fig,palms,pear,and ornamentals.In the USA it is currently only found in Florida, although it is distributed throughout much of the rest of the world and frequently affects citrus and fig production in Europe. The environmental conditions throughout much of California are considered favorable for this scale to establish if it is not eradicated and prevented from re-entering.
For more on this scale and other recent topics, check out the Topics in Subtropics Newsletter:

Statewide citrus bearing acreage relatively stable for past three seasons
The Pacific Regional Office of the USDA's National Agricultural Statistics Service (NASS) conducts an acreage survey of California citrus growers as funding is available. The purpose of this survey is to provide bi-annual citrus acreage, which includes information on new plantings and removals. It is the continuation of a long series of industry-funded Citrus Acreage surveys.
This report consists of two parts:
- Table 1 shows estimated statewide bearing acreage for the 2020-21, 2021-22 and 2022-23 seasons.
- Tables 2, 3, 4 and 5 show detailed acreage data by type, variety, and year planted -- as voluntarily reported by citrus growers and maintained in NASS' database.
With perfect information, the estimated statewide bearing acreage and the detailed acreage data would be the same. Generally, this will not be the case for the following reasons:
- A voluntary survey of approximately 5,000 citrus growers is unlikely to ever attain 100 percent completeness.
- It is difficult for USDA/NASS to detect growers who are planting citrus for the first time.

Hello everyone, I'm the new UC IPM Entomology Advisor serving the communities of Monterey, Santa Cruz, and San Benito Counties. Born and raised in the Santa Clarita Valley, I'm excited to return to my home state of California.
Inspired by a lifelong passion for insects, I pursued bachelor of science in degrees in Entomology and Plant Pathology at Cornell University in Ithaca, NY. At Cornell, I was first exposed to the world of cooperative extension, working in a lab to study and support natural enemies of spider mites, aphids, thrips, fungus gnats, and whiteflies in greenhouses.
In partnership with Montpellier SupAgro and the Università degli Studi di Torino, I received a Master of Science degree in Viticulture and Enology. For my master's thesis, I worked with Italian grape growers on understanding the ecology and management of leafhopper vectors of the pathogen responsible for European grapevine yellows (Flavescence dorée phytoplasma).
For my PhD, I studied Environmental Science, Policy, and Management at the University of California, Berkeley. At Berkeley, I worked with grape growers and cooperative extension advisors in Napa and Sonoma county to understand the role of spittlebug insect vectors in spreading Xylella fastidiosa, the bacteria responsible for Pierce's disease of grapevine.
After Berkeley, I have worked as a postdoc at Washington State University with cherry and blueberry growers to adapt and adopt innovative and internationally recognized practices for sustainable management of Spotted-Wing Drosophila (SWD). As part of that work, I have closely partnered with growers, pest control advisors, USDA scientists, cooperative extension advisors, and industry representatives on SWD projects related to biological control, cultural control, behavioral control, and pesticide resistance screening and management. Additionally, I was part of a team that worked to coordinate SWD management with the management of the leafhopper vectors of X-Disease phytoplasma in cherry.
With 15 years of experience in New York, California, Washington State, France, and Italy, I'm excited to collaborate with you all to support the development and adoption of innovative, cost-effective, and sustainable insect pest management practices. I aim to develop partnerships, lifelong relationships, and projects that center and elevate grower voices, experiences, and leadership. Together, I hope that we can not only address the threat that agricultural insect pests pose to our three counties but also help to support the many communities and ecosystems that interface with our agricultural livelihoods. Please feel free to reach out to me at 831-759-7359 or djbeal@ucanr.edu. The Bug Doctor is in to look at any insects you may find!
