Dogs uncover spotted
lanternflies, other pests
Virginia Tech scientists, including dog trainer and doctoral student Sally Dickinson, are examining how dogs can
discover spotted lanternflies. The pest damages grapes and other crops, including apples, peaches, cucumbers
and tree nuts. Photos courtesy of Virginia Tech.

esearchers are employing a novel approach to
help growers discover and deal with spotted
lanternflies (SLF).
Virginia Tech scientists are working with dog
handlers to train canines to detect SLF, a destructive
pest that feeds on a wide variety of crops and plants,
including grapes, apples, cherries, nectarines,
apricots, peaches and plums, as well as almond and
walnut trees.
Researchers want to develop a network of citizen
scientist dog handlers who can be dispatched to
detect the latest invasive species.
" For SLF, we found that dogs can be trained to
detect spotted lanternfly eggs, which can help us to
detect eggs, " said Mizuho Nita, a Virginia
Cooperative Extension specialist and an associate
professor of plant pathology in VA Tech's School for
Plant and Environmental Sciences. " I think it is useful
especially at the front of SLF movement since SLF
lay eggs on many different surfaces, including
stones and pallets. "

Unofficially called the Canine Citizen Science Study,
the project is funded through a four-year $475,000
grant from the USDA's Agriculture and Food Research
Initiative. It began in 2021 at Texas Tech University's
Canine Olfaction Research and Education Laboratory
and expanded to the East Coast, where SFL is prevalent.
At Virginia Tech's Alson H. Smith Jr. Agricultural
Research and Extension Center in Winchester, Virginia,
scientists are asking dog owners to unite and employ
their pets' skills to sniff out SLF eggs.
SLF can be spread long distances through movement
of infested material or items containing spotted lanternfly
egg masses. Not limited to agriculture, SLF can also be a
big nuisance to the landscape and residential industries.
The insect sucks sap, young stems and leaves,
causing tree withering, reducing photosynthesis,
weakening plants and eventually leading to plant
death. Feeding causes plants to weep or ooze, creating
a fermented odor. Trunks display a grayish-black
trail of wounds. The insects excrete large amounts of
honeydew, covering stems and leaves as well as the
ground below infested plants. Established populations
in Pennsylvania vineyards have caused yield losses of
up to 90%.
