Spotted lanternfly a new invasive concern: Update on range expansion

 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, krpeer@vt.edu, or 276-694-4135.
This event is sponsored by Virginia Cooperative Extension, Virginia Department of Agriculture and Consumer Services, and Virginia Tech.

Spotted lanternfly egg first hatch for 2022 was reported on 21 April. First adult emergence for 2022 was noted on 11 July. This new invasive pest of vineyards and other small fruit crops moved into eastern Pennsylvania in 2014, and has been spreading.  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.

Links to the quarantine map and quarantine protocol may be found here. One of the requirements of the protocol is one person at each operation becoming certified to insect produces and conveyances leaving the quaranine zone. The certification program may be found here. This pest poses an important risk for grape, orchard and tree crops.  Click here for a recorded 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).  Specific fact sheets for vineyards and residential areas have been posted.  Now that spotted lanternfly has been found in Virginia, it will be important to follow its spread through the state.   For a current Virginia map, click here.    To report a suspected find, please follow this link:  https://ask2.extension.org/widget.html?team_id=1981?default_location=VA?default_county=All.

Spotted lanternfly a new invasive concern: Update on range expansion

Spotted lanternfly egg first hatch for 2021 was reported on 28 April.  First adult emergence for 2021 was noted on 9 July.  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).  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 lanternfly is now found in Albemarle, Augusta, Fauquier, Madison, Page, Prince William, Rockingham, Shenandoah and Warren counties, plus the City of Lynchurg. Spotted lantern fly is now established in New Jersey, Ohio, Delaware and Maryland, and has been reported from two counties in West Virginia.  This pest poses an important risk for grape, orchard and tree crops.  Click here for a recorded 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).  Specific fact sheets for vineyards and residential areas have been posted.  Now that spotted lanternfly has been found in Virginia, it will be important to follow its spread through the state.   For a current Virginia map, click here.    To report a suspected find, please follow this link:  https://ask2.extension.org/widget.html?team_id=1981?default_location=VA?default_county=All.
 
Periodical 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 to the web page linked in the title, check out this recorded 20-minute presentation.

Corteva to cease production and sale of chlorypyrifos:
On Feb 6, Coreteva announced it will cease production and sale of chlorpyrifos, the active ingredient in Lorsban.  The statement cited economic factors.  This material has been in the news lately, for human health and regulatory concerns.  In November 2015, EPA announced its plan to revoke all tolerances because of neurodevelopmental problems resulting from neonatal exposure.  However, the plan was subsequently reversed following a call for more comments in November 2016, finalized in July 2019.

 Spotted lanternfly a new invasive concern

A new invasive pest of small fruit crops and vineyards moved into eastern Pennsylvania in 2014, and has been spreading.  The quarantine zone for 2020 added 12 new counties, bringing the total to 24 Pennsylvania counties.  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).  Specific fact sheets for vineyards and residential 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, please follow this link:  https://ext.vt.edu/spotted-lanternfly.

 VDACS establishes quarantine for spotted lanternfly

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.  They are now in the second instar, or second nymphal stage.

The press release on the SLF quarantine linked 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.
For questions on the quarantine and related issues:
For questions about the quarantine or movement of material or trucks, or the compliance agreement, call VDACS.  Call the Richmond number (804-786-5525) even if its a question about the Winchester area.
For questions about the training for the SLF Detection Credentials, go to:  ext.vt.edu/spotted-lanternfly.  Look for a purple button the right side of the page to start the process.

For suspected finds of SLF, go to either the detection portal:

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.

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 advisor.  Lists of 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 more information, contact Doug Pfeiffer (dgpfeiff at vt.edu) or Sharon Proffitt (sproffit at vt.edu) (see 2008-2009 Extended Campus tuition rates).

Mating disruption and Organic certification:
The National Organic Standards Board has recently amended organic guidelines so that many pheromone dispensers for mating disruption will now be allowed in organically certified orchards.  Most hand-placed dispensers are now considered to emit negligible amounts of inerts, and will be allowed.  Sprayables and puffers will not be allowed.  More information will be posted when available.
