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 to

lanternfly egg first hatch was reported on 22 April.
This 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 and egg
masses were found in Winchester in January 2018
(actually 2017 individuals) and in Clark County in November
2019. Spotted lantern fly is now established in New
Jersey and Maryland, and has been reported from one county in
West Virginia. This pest poses an important risk for
grape, orchard and tree crops. Click here for an Adobe
Presenter talk on this species. A fact
sheet is available from Virginia Tech (a
USDA fact sheet is available in Spanish). In
addition, there is a Virginia Tech Pest Alert, with
additional information on recognition and reporting (this is
also available in Spanish).
sheets for vineyards
areas have been posted. Now
that spotted lanternfly has been found in Virginia,it will be important to follow its spread
through the state. To report a suspected find,

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.

Revisions to Fruit Pest Management recommendations:
The revised Pest Management Guide
for Home Fruit, Commercial Vineyards, Commercial Small Fruits,
and Hops, are now available. The tree fruit manual,
separate from the Pest Management Guide series, is in
production, and we hope to have it ready for our fruit
The guides are available free online
in PDF, and will also be available for purchase.
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
