Spotted lanternfly (SLF) is a potentially devastating pest of grape, now expanding its spread in Virginia. In July 2022, VDACS expanded a quarantine zone from 3 counties to 12, including contained independent cities.
Many vineyards and wineries will now need to deal with the quarantine protocol. At least one person per company will need to get certified through a short, on-line training session ($6.00). That person may train others in the company to assure compliance. All shipments and vehicles leaving the quarantine zone will need to be inspected. Information on the quarantine protocol may be found here (https://www.vdacs.virginia.gov/plant-industry-services-spotted-lanternfly.shtml). This site contains the protocol as well as the current version of the quarantine map.
The training required for certification is easy and inexpensive. Access to the training may be found here (https://register.ext.vt.edu/search/publicCourseSearchDetails.do;jsessionid=E3FEE1B1C1921BA6848B382063FC0BDE?method=load&courseId=1066947).
When doing inspections for quarantine compliance, it will be necessary to know what life stages of SLF can be expected. We have graph posted online that conveys this information clearly (https://www.pubs.ext.vt.edu/ENTO/Ento-268/ENTO-268.html). This can be posted where appropriate in your operation.
Theresa Dellinger and Eric Day in the Department of Entomology have created a useful aid for the public on the SLF quarantine, entitled "What Virginians Need to Know About SLF Quarantine expansion" (https://www.pubs.ext.vt.edu/ENTO/ENTO-319/ENTO-319.html).
Beyond matters of quarantine compliance, we have online resources for SLF management. There is a fact sheet on SLF management, available in English and Spanish, available here (https://www.pubs.ext.vt.edu/ENTO/ENTO-323/ENTO-323.html). In a similar fashion, a fact sheet for SLF management in residential areas (https://www.pubs.ext.vt.edu/ENTO/ENTO-322/ENTO-322.html).
Needless to say, SLF is covered in our annual chemical control recommendations for vineyards and home fruit. The risk to tree fruits is not considered to be as great; SLF will be included here as needed. It should be noted that orchardists will still need to deal with quarantine issues.

Last but not least, I maintain a spotted lanternfly page in the Virginia Fruit Site ( https://www.virginiafruit.ento.vt.edu/SLF.html). I intend for this to be one-stop shopping for matters on SLF, and all the above links are active there.
I hope this is useful. More later, Doug
