Why is the Glassy-Winged Sharpshooter a Threat to Sonoma
County?
Sonoma County's
Work Plan
In July 2000, the State of California required each county to submit
a work plan to stop the spread of the Glassy-Winged Sharpshooter. Because
the State did not allow counties to stop incoming plant shipments from
infested areas of Southern California due to concerns about restriction
of trade, Sonoma County prepared a work plan that includes many different
methods to fight the insect, and protect the ecology and economy of
Sonoma County.
The work plan is
currently under review. As soon as plan modifications are approved,
we will post the plan and its modifications here.
The current work
plan includes the following elements:
1. Exclusion and
early detection efforts are the top priorities, and are briefly described
below.
2. Control and eradication of Glassy-Winged Sharpshooters, if they do
make their way into Sonoma County, are the other components of the work
plan. Options for treatment vary depending on the stages of life found
in an area. For example, an egg
mass on one plant in a yard could possibly be dealt with by simply
removing the plant to protect other plants and trees in the area. Because
the State approves the use of locally applied ground spraying of pesticides,
these have been included in the work plan for certain infestations,
with careful monitoring, etc. These components are under review right
now, and as soon as the plan is finalized, we will post the plan on
this site.
Exclusion
Our #1 priority is prevention, or exclusion, of the Glassy-Winged Sharpshooter.
We cannot control Mother Nature, but there are things we can do to keep
it out of Sonoma County as long as possible. We need everyone's participation
in this effort, and we hope that, working together, we can keep it out
of our county until effective organic treatments are available and approved
by the State.
The counties of
Napa, Sonoma, Solano, and Marin are inspecting incoming plant shipments
from Southern California, because we cannot stop the shipments. Our
County inspection teams are doing everything they can to inspect the
incoming plant shipments that have the potential to host the Glassy-Winged
Sharpshooter.
Please support this
prevention program by shopping at local garden stores, nurseries and
landscapers that sell only inspected plants. Beginning in May, please
look for a Certificate of Compliance with a "Sharpshooter Spotter"
seal, signed by the Sonoma County Agricultural Commissioner John Westoby,
at your local retailer. This Certificate tells you that the retailer
cares enough to offer you plants that have been inspected for the Glassy-Winged
Sharpshooter. The local retailers that are in compliance with this inspection
effort to keep Sonoma County beautiful will also have brochures available
for you, so you can learn more about the Glassy-Winged Sharpshooter.
In May, we will
have a list available here that will include nurseries, retailers and
landscapers that are in compliance with the program. Please bookmark
this page, and check back then so you can support their efforts to keep
our county!
Early Detection
The Agricultural Commissioner's team has placed a large number of sticky
yellow cardboard traps in both residential areas and agricultural land.
These traps are checked regularly for Glassy-Winged Sharpshooters and
other pests. As of today no Sharpshooters have been found in Sonoma
County on these traps.
If you are interested
in helping out and want to have these sticky yellow traps on your property,
please call the Sonoma County Agricultural Commissioner's office at
(707) 565-2371.
Members of the County
inspection team routinely do visual inspections of residential and agricultural
land, and areas that are close to bodies of water, such as creeks or
rivers, known as riparian areas. County inspectors focus primarily on
newly landscaped areas that may have added plant material in the last
few years.
The County's survey
work includes neighborhoods, so an inspector may come to your door and
ask to inspect your back yard for evidence of Glassy-Winged Sharpshooters.
· Always ask the inspector for identification.
· If you give the inspector permission to inspect your back yard,
you will have the opportunity to talk with them about survey work you
can do in your own yard.
· If you do not give the inspector permission to inspect your
back yard that day, they will not just force their way onto your property.
We hope that after visiting this site you'll realize how important this
issue is, and allow the inspection of your back yard.
· If the inspector is in the neighborhood and stops by when you're
not at home, they will leave a pamphlet about the Glassy-Winged Sharpshooter
to let you know that they were in the area. Don't worry - they won't
go into your back yard if you're not there, or have not given them permission
to go there!
You Can Do Your
Own Surveys!
Take frequent walks around your yard or neighborhood park, and keep
your eyes open for the insect or its egg
masses. The Glassy-Winged Sharpshooter typically lays its eggs on
the underside of leaves, but adult
insects can be anywhere on a plant or tree.
If you find an insect
that you think might be a Glassy-Winged Sharpshooter or a suspicious
egg mass, try to collect
the evidence in a plastic bag, film canister, jar or food container
so we can make the proper identification. We've found it's easiest to
collect these insects in the early morning when the temperature is cooler.
Because the Glassy-Winged
Sharpshooter drains a large amount of water out of every plant it feeds
on, it then excretes
a liquid called Sharpshooter rain
that leaves a white stain on anything outdoors - patio furniture, plants,
cars and sidewalks, etc. If you see stains you think may be their Sharpshooter
rain, you may have them in the area.
If you find evidence
of an insect, please call the Sonoma County Agricultural Commissioner's
office at (707) 565-2371. By asking you a few questions about the insect,
we'll try to determine if it is a Glassy-Winged Sharpshooter. If we
think it is, you can drop the specimen off at the Sonoma County Agricultural
Commissioner's office or we can come by and pick it up.
What happens if
you or a member of the County's inspection team find a Glassy-Winged
Sharpshooter on your property? The flow chart describing the current
procedures that the County will follow are available for you here, but
these too, are under review.
Education and
Outreach
If the Glassy-Winged Sharpshooter were to establish itself here in Napa
County, we would all feel the consequences. The County's efforts include
letting all stakeholders - that is, people who live, visit, or work
here - know about the insect and what they can do to assist in prevention
and early detection. This website is part of that program.
We also have informational
brochures, posters, a video, slide show, an educational curriculum,
and a PowerPoint presentation in Spanish and English, available for
clubs, camps, schools, and any organization that is interested in helping
to educate Sonoma County citizens about what they can do to protect
our beautiful county. Call 1-866-BUG-SPOT
for more information.
Why
is the Glassy-Winged Sharpshooter a Threat to Sonoma County Ecology
and Economy?
How the insect hurts the ecology around us:
The Glassy-Winged Sharpshooter is leafhopper insect that has a stylus
- like a little drill - that bores through wood. With this unique apparatus,
the insect can transmit lethal diseases into the wood portion of plants
and trees. With this stylus, it also sucks life-giving water out of
all the plants it feeds on. Each adult
Glassy-Winged Sharpshooter sucks out 200 to 300 times its body weight
in water every day. This is the equivalent of an adult human drinking
4,300 gallons of water per day! This loss of water that every living
thing needs is even hurting our oak trees, that are trying to fight
off other diseases, as well.
Unlike its relative,
the Blue-Green Sharpshooter, that just feeds on tips of plants that
can be pruned away, the Glassy-Winged Sharpshooter can damage many trees,
crops and plants because of its ability to transmit diseases into woody
parts of plants, trees and crops that cannot be pruned away. Please
see the list of plants that serve as a host to the Glassy-Winged Sharpshooter.
How the insect
could hurt our economy:
Not only can Glassy-Winged Sharpshooters wipe out table, wine and raisin
grapes, it also spreads a lethal disease that affects almonds, alfalfa
and many other crops. The damage to these crops would affect the field
workers and farmers who grow them, and many other people, as well.
These crops support
a huge variety of other jobs. For example, the wine grape industry is
the primary reason that tourists come to Sonoma County, according to
the California State Tourism Board. The tourism industry brings in approximately
$190 million into Sonoma County every year and supports about 16,000
jobs. Those jobs are in jeopardy if the Glassy-Winged Sharpshooter becomes
established in Sonoma County. And the money spent locally by those people
would affect even more of us - from local bookstore and coffee shop
owners to auto mechanics.
The high-tech boom
just south of us affects Sonoma County's economy, and we have seen prices
rise steeply over the past years in many sectors of our economy. For
example, because of the rise in land prices, grape crops are one of
the only crops that can compete with the push for new housing developments
and other commercial enterprises.
If the Glassy-Winged
Sharpshooter wipes out the grapes in Sonoma County, just as it did in
Anaheim, California many years ago, we will have no green, living crops
to compete with the economic impact of the high-tech boom.

in May - please bookmark this page and check back then!
To protect your
yard and neighborhood and our beautiful county, please support local
establishments that offer plants and trees that have been inspected
for evidence of Glassy-Winged Sharpshooters. Look for a Certificate
of Compliance from the Sonoma County Agricultural Commissioner when
you shop for outdoor plants, so you know that the establishment cares
enough to offer you plants that have been inspected, in an effort to
protect our beautiful county. The "Sharpshooter Spotter" seal
on the Certificate may also appear in advertising done by these compliant
establishments. Please support these local businesses!
