Spotted lanternfly training session: A Spotted Lanternfly Training Session for Christmas Trees, Tree Fruits, Grapes & Horticultural Products will be offered in Wytheville. There will be an in-person spotted lanternfly training course that will be held September 29, 2022 from 10:00 am – 12:30 pm at the Wytheville Meeting Center in Wytheville, VA. This training will be for producers of Christmas trees, tree fruits, grapes, and other horticultural products including vegetables.
This training will introduce the Spotted Lanternfly, and will dive into its spread, resources for growers, control methods, regulatory updates, and will provide information on how to comply with the SLF quarantine and permitting requirements.
The course is free, but registration is recommended to Kyle Peer, firstname.lastname@example.org, or 276-694-4135.

During the 2018 season, the infestation zone in Virginia expanded from approximately 1 square mile block in Winchester, Frederick County, to about 18 square miles, and 40 square miles in fall of 2019. By the end of the 2020 season, the zone encompassed 140 square miles. On May 28, 2019, the Virginia Department of Agriculture and Consumer Services (VDACS) announced the establishment of a quarantine to limit the spread of SLF; this zone was significantly expanded in July 2022. As of 2022, in addition to the original counties of Frederick, Clarke and Warren, SLF is established in Albemarle, Augusta, Carroll, Page, Prince William, Rockingham, Rockbridge, Shenandoah and Wythe Counties, plus the cities of Buena Vista, Charlottesville, Harrisonburg, Lexington, Lynchburg, Manassas, Manassas Park, Staunton and Waynesboroor a map of the current Virginia distribution. This includes the entire Shenandoah Valley, with spread further into the Virginia Piedmont.

2014, and has been spreading. The
Pennsylvania quarantine zone for 2020 added
12 new counties, bringing the total to 24
counties in that state. This
infestation now reaches the Ohio
border. In 2017, the
range increased from 6 to 13 Pennsylvania
counties, and also into Delaware, New York and
northern Virginia. Specimens of dead
adults and egg
masses were found in Winchester in January
2018 (actually 2017 individuals). In 2020,
the Winchester infestation became more intense,
and spread to Gore in the western part of
Frederick County, and into central Clarke County
in November. This included the first
collection at a commercial vineyard. Spotted lanternfly
is now found in Albemarle,
Augusta, Fauquier, Madison,
Page, Prince William,
Rockingham, Shenandoah and
Warren counties, plus the City
of Lynchurg. Spotted

establishes quarantine for spotted
Late Tuesday afternoon (5/28), Virginia
Department of Agriculture and Consumer Services (VDACS)
announced the establishment of a quarantine for spotted
lanternfly (SLF), an invasive pest insect that was found in
Winchester in January 2018 (ext.vt.edu/spotted-lanternfly). This insect threatens to be a major
pest of fruit crops, forest trees, and other plants in
Virginia. Despite an eradication effort in 2018, SLF
increased its distribution from about 1 square mile to 16
square miles. This year, the overwintering eggs began
their hatch on April 27, earlier than last spring..
The press release on the SLF
here. A direct link to the quarantine
document is linked
here as well. The regulated area includes the
City of Winchester and Frederick County. Some of the
key provisions of the quarantine are:
1) Regulated articles (plants, outdoor
industrial materials, shipping containers, outdoor
household articles, and others) may be moved from the
quarantine area if they have been inspected, and are
accompanied by a permit;
2) Regulated articles may be moved
within the quarantine area following an inspection; a
certificate is not required.
3) From April 1-Dec 31, regulated
articles may be moved through the regulated are without
stopping, or stopping only for fuel or traffic conditions.
4) To obtain a permit to move regulated
articles, a person doing business must complete a
VDACS-approved training (see below) and agree to train
employees on identification of SLF.
The training needed to obtain a SLF
permit is available
online. There is a $6.00 fee.

Brown marmorated stink bug and Virginia fruit: See
StopBMSB.org web site! A new addition to the stink
bug complex is brown marmorated stink bug, Halyomorpha halys (Stål). Brown
marmorated stink bug (BMSB) has recently been introduced from
Asia into the northeastern U.S. It was first detected in
1998 in Allentown, Pennsylvania (see NAPIS map;
this map underrepresents the situation in Virginia). It was later found in New
Jersey, Maryland and Delaware, and in October 2004 it was
found in Montgomery County, Virginia, and in Tennessee in
2008. Injury in tree fruits
can be severe, exceeding 25% (individual blocks have been
estimated to have much higher levels of fruit injury).
Externally, fruit may have multiple reddish dents at feeding
sites, resembling hail strikes. Upon cutting into fruit,
corky areas are seen in the flesh of the fruit. In vineyards, a unique problem is posed.
Stink bugs may be harvested along with clusters and be
transported to the winery in lugs or bins, where the wine can
be imparted with a "stink bug taint". Research is
underway to test short-residual insecticides to knock down
BMSB from clusters at harvest. For further information and images, see the Brown marmorated
stink bug page. A working group on organic management of
BMSB has been established, with their own web site.
There is opportunity to participate in grower forums. Listen to Adobe Presenter

Spotted wing drosophila:
A new invasive pest of small fruit crops and vineyards moved
through Virginia in late summer 2011. Spotted wing
drosophila, Drosophila suzukii,
differs from other species of vinegar or pomace flies in that it
lays eggs in ripening fruit on the vine or plant, rather than in
overripe or rotting fruit material. This has the potential
to be a major problem for growers of soft-fruited crops.
More information is posted in a SWD page
in the Virginia Fruit web site. Hear an Adobe
Presenter presentation on spotted wing drosophila in
vineyard and berry crops. In May 2013, 24(c) labels were
approved for malathion 8F for blueberries and caneberries grown in
Allowing up to 2.5 pts/acre for spotted wing drosophila.
Maximum number of applications is 2, with a minimum of 5 days
between applications. Do not exceed a total maximum from all
sources of malathion of 5 lb ai/acre/year. Do not apply
within 1 day of harvest. Caneberries: Allowing an additional application for spotted wing
drosophila. The maximum application rate is 2.0
pts/acre; the maximum number of applications per year is 4, and
the minimum retreatment interval is 7 days. Do not exceed a
total maximum use rate of all sources of malathion of 8 lb
ai/acre/year. Do not apply within 1 day of harvest.

New! The College of Agriculture and Life
Science at Virginia Tech has established a new on-line Master's in
Agriculture and Life Sciences. This curriculum
has been approved by the State Council of Higher Education and is
now accepting applications for Fall semester 2007. In this
program, you can earn a master's degree in agriculture while
working in your current job - emphasis is on education for
place-bound learners, and all courses are taken on-line. In
addition to a core area, there are courses offered in five areas
of concentration: (1) Biosecurity, Bioregulations and Public
Health, (2) Education, (3) Environmental Science, (4) Food Safety,
and (5) Plant Science and Pest Management. In addition to
course work, the student completes a
project decided upon in consultation with your major
courses within each concentration may be found in the web
site linked above. This program was recently the subject of
an interview by Jeff
Ishee with Virginia Public Televsion's Virginia Farming. For
