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.

reported on 28 April.
2021 was noted
on 9 July.
new invasive pest of small fruit crops and
vineyards moved into eastern Pennsylvania in
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
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. There
is a reproducing population in Augusta County,
with individual insects found in Warren and Page
counties. The quarantine has been expanded
to include Frederick, Clarke and Warren counties.
Spotted lantern fly is now established in New
Jersey and Maryland, and has been reported from
two counties in West Virginia. This pest

cicada broods active in 2020 and 2021
There are 15 broods of periodical cicada. Two of
these will be affecting Virginia fruit growers this
year (Brood 9) and next Brood 10). Emergence of
adults is expected in early-mid May. Adults first started appearing in Patrick County
apple orchards on 17 May. The egg-laying behavior of females will lead to death of
pencil-diameter branches, and can be devastating to
young orchard and vineyard blocks. In addition

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.

Proposed pollinator protection
have been at greater risk in recent years because of
Colony Collapse Disorder, which results from a
combination of stress factors. In order to
address this, the Virginia Department of Agriculture
and Consumer Services has created a draft plan to
protect pollinators from pesticides has been
developed. In preparation for a June meeting
in Richmond, grower, extension agent and beekeeper
feedback is requested. The draft
plan is linked here. A web application

New insecticide mode of action
for spotted wing drosophila: A new insecticide has been
approved by EPA, and received a state label in Virginia on 14,
2014. Exirel has the common name cyantraniliprole, also
known as cyazypyr. This product is approved for
bushberries, including blueberries, and stone fruits,
including sweet and sour cherries. The use rate for
this pest on each of these crops is 13.5-20.5 fl oz per acre,
with a 3 d PHI. It is not approved for caneberries or
Spotted wing drosophila:
A new invasive pest of small fruit crops and vineyards moved
through Virginia in late summer 2011. Spotted wing
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
Virginia. Blueberry: 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.

Brown marmorated stink bug and Virginia fruit:
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
