MG President’s Message copy of the Bylaws will be emailed to each member for consideration. Then we will vote to approve the new Bylaws at the January meeting. My sincere thanks to Debbie Scott for reformatting how we account for funds received, funds budg-eted and funds dispersed. As a 501(c)(3) organization, we have significant accounting responsibili-ties. In any 501(c)(3) organization it’s all about “follow the money.” In this regard, Debbie has done a wonderful job! Thanks Debbie. For the next two months, the Board will be formulating our 2016 Budget. As a 501(c)(3), we must have a budget. The budget is subject to review when we file our application with the Virginia De-partment of Agriculture and Consumer Services (VDACS) in the spring requesting permission to seek donations actively and conduct fundraisers (as defined by the IRS). Once our VDACS applica-tion is approved, we will request relief for paying state income tax and collecting and paying state sales tax. The Board needs new ideas on how to reach out to the Prince William County community and as-sist in various programs such as, possibly, grants to schools and community organizations to create gardens or flower beds. As a 501(c)(3) organization, community outreach is expected. We have a list of ideas but new ideas are always welcome. It is my wish that, by the January meeting, the Board will have approved some new community projects and you will be able to sign up to help out. We have a great deal to accomplish in the remaining months.

Respectfully, Bill Willis, President, Master Gardeners of Prince William, Inc.

Master Gardeners Visit Alpaca Habitat by Harriet Carter

B onnie Nahas Fulford is the owner of a small herd of alpacas. She is currently feeding them grain and

other supplements. Her goal, though, is to have a grazing habitat in her backyard (she has a meadow in her front yard) so that the animals could feed on fresh grasses and plants. The project for our team of Master Gardener Volunteers, Linda Arvin, Brenda Hallam, Teresa Blecksmith, Sherrie Bishop and myself, involved identifying plants in Bonnie’s backyard meadow potentially poisonous to the alpacas. It was quite an extensive task for the Master Gardener Volunteer team to identify the plants on the ground, overhanging tree branches, as well as vines on the fence. We accomplished most of it within a couple of hours.

A lot of the plants were weeds we knew from turf projects, but there were many that were difficult to identify with certainty. Part of the difficulty was that the plants were at various stages of growth and only a few were in flower. The plants we could not identify were bagged and taken to the Extension Office for possible identification. The office experts, Paige Thacker, Nancy Berlin, Thomas Bolles and

Leslie Paulson were able to identify all but one. We compared all of our identified plants against a complete listing of plants poisonous to alpacas. Bonnie was then given a printed out list with color photos which made it much easier for her to check against what is actually growing on her grounds. There were some amazing finds. Plantains, for

example, are not poisonous when they are in the broad leaf form, but they are deadly in the narrow leaf form. Bonnie’s backyard meadow, with its current plant life, may have to be completely resown with grasses and plants that are palatable to alpacas -- no small task. However, renovation could be done in stages.

Emerald Ash Borer by Abbie and Vincent Panettiere

S ome years ago, I can recall seeing odd pur-ple tent-like structures hanging from trees along Sudley Road across the road from

the Catharpin Post Office. I believe this was part of a 2012 program, “Spot the Purple Trap for EAB Awareness Week." The tents were traps for the Emerald Ash Borer (EAB), Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), a small invading beetle native to Eastern Rus-sia, Northern China, Mongolia, Korea, Japan, and Taiwan. The traps were purple because the insects are said to prefer that color.

In their native range, the EAB population densi-ty is low enough that they are considered merely a pest on the ash trees. However, outside their native territory, they have become a serious pest, spreading through the United States and destroying all varieties of ash in this country.

The purple tents are something similar in intent to the traps that lure Japanese beetles: they were developed not specifically as killing traps, but an attempt to assess whether there are EABs present in the area and their estimated number. The tents are extremely sticky to trap any EABs and are armed with a pheromone (a pheromone is a chemical sexual lure secreted by animals, but particularly by insects to attract others of the same species).

The program became a necessity in the years fol-lowing the first discovery of the insect in North America, made in 2002. The beetle had been at-tacking ash trees in and around Windsor, Ontar-io and Southeastern Michigan. It is thought that the beetles first made their way to this country in pallets used for shipping and packing materi-als, or shipping containers. Due to the extent of damage confirmed in 2002, it is thought that they first arrived here in the early- to mid-1990's.

The federal government has placed various are-as in the East and Midwest under quarantine to try to stop or slow the advance of EAB to new

territories. Under quarantine, according to the Fairfax County, Virginia website, you are not allowed to move any hardwood firewood, ash nursery stock, ash green lumber, or any other ash material, living, dead, cut, or fallen, includ-ing logs, stumps, branches, and roots, as well as composted and uncomposted chips from any spe-cies of ash.

EAB insects are small, approximately .33 inches long, and brilliant metallic green as adults. EABs have four larval stages (instars) and, in the process of feeding, they create long serpen-tine galleries. They use the volatiles from ash leaves and what are called “sesquiterpenes,” (these are naturally occurring chemicals given off by the trees as a defense or a pheromone) to locate their host trees. When they emerge as adults from trees in the spring, they make a D-shaped opening in the tree’s bark. The adults will spend approximately one week feed-ing on the leaves in the ash tree’s canopy, but this itself does not do much harm to the tree. Males hover nearby, identifying females visually and dropping on to them to mate. Females may mate with several males in their six week life span in which they will lay forty to seventy eggs. If the females live longer, they may lay up to 200 eggs, which will take about two weeks to hatch. The eggs can be found between bark crevices, flakes, or cracks in the tree. When the larvae have hatched, they chew through the bark to the phloem, cambium, and xylem areas where they feed, and it is in this stage that the EABs do their harmful work.

An article from Purdue University Purdue Ex-tension covering the EAB in Indiana mentions that “ash trees are considered ring‑porous, which means that their vascular vessels are rel-atively large and concentrated directly under the bark. This characteristic makes ash trees espe-cially vulnerable to attack by EAB larvae, which restrict their feeding to tissue in the ash tree’s cambium layer. The vascular systems of dif-

Turnip News

fuse‑porous trees, such as birch, are charac-ter-ized by vessels spread evenly throughout the sapwood.”

When the insects reach the fourth-instar stage, they will be around an inch in length. In fall, they excavate half-inch chambers into the outer bark or sapwood, fold themselves into a J-shape, and develop into pupae and then adults by the following spring.

The damage is done to the ash tree by the gal-leries that the larvae excavate, which become so extensive that nutrients and water can no longer flow to all parts of the tree. The tree is effectively gir-dled and dies within two to four years, as it is denied suste-nance.

EABs are strong fliers, but gen-erally stay within a half-mile area all their lives. Left to their own devices, the infestation would travel at about two miles per year, but because of the shipment of untreated ash prod-ucts, ash firewood, ash nursery stock, and other ash products, the spread of the beetle has rap-idly covered a great deal more territory.

When EABs attack a new territory, they are drawn first to stressed trees rather than healthy ones, but after a while, they will attack all ash varieties that are over an inch and a half in di-ameter. EAB kills young trees several years be-fore they reach the age where they begin making seed(ten years). An EAB attack will always prove fatal to ash, even healthy trees, in two to four years.

Since its introduction into North America, EAB has spread into 15 states (Illinois, Indiana, Io-wa, Kentucky, Maryland, Michigan, Minnesota, Missouri, New York, Ohio, Pennsylvania, Ten-nessee, Virginia, West Virginia, and Wisconsin) and two Canadian provinces (Ontario and Que-

bec), killing tens of millions of trees in the pro-cess.

Sadly, in New York, and presumably other ur-ban and suburban areas, ash were used to re-place elm trees when those were destroyed by Dutch elm disease. The loss of the popular and economically very valuable ash tree species is likely to be devastating economically. Further, the loss may well seriously affect the control of air pollution, local temperatures in the area as the tree canopy is altered, and adversely affect

stormwater runoff.

With the seriousness of the sit-uation well understood, efforts are underway on many fronts to find ways to stop or at least slow the destruction wrought by EABs. I have mentioned the sticky purple tents already. An-other attempt, by both United States and Canadian agencies, to ascertain how many beetles there may be in an area in-volves the use of native parasit-ic wasps, (Cerceris fumipennis). The normal diet of these para-sitic wasps includes beetles from the same family as the emerald ash beetle, and the wasps will use EAB for food if

they are present. The female wasps stun the beetles and bring them back to their in-ground burrows. The beetles are stored until the wasp’s eggs hatch, at which point the wasp larvae use the beetles as nourishment.

Volunteers working on this particular project have a tricky assignment: to catch the wasps on their way home with their beetle prey. They then ascertain if there are any EAB among the potential wasp larvae dinner and, if so, the agency in charge of the study may initiate quar-antine measures. This effort is called “biological surveillance” instead of “biological control” be-cause, unfortunately, the wasps don’t seem to affect the beetle population density.

Biological control is being attempted on several fronts. Quite sensibly, scientists visited areas in Asia where EABs are native. Three species of parasites from China were approved for release by the USDA in 2007 and authorities in Canada in 2013, and another species was approved for release in 2015. Remembering what can happen when a species is introduced with the sincere belief that it will attack only the invader caus-ing the trouble, they have imported species which will attack EAB, but feel they’ve been careful in selecting parasites that don’t seem to cause harm except where intended.

To locate EAB, ash specimens may be girdled in the fall, so they may act as a trap tree. Egg-laying EAB females are attracted to the tree in spring, and in fall the tree is debarked to search for larvae. If their presence is confirmed, the ar-ea is then put under quarantine to try to keep the infestation as local as possible.

Michigan and other Great Lakes states, which have been particularly hard hit by EAB, are be-ginning to collect native ash tree seeds in an ef-fort to preserve biodiversity. The seeds will be stored at the National Seed Laboratory in Dry Branch, Georgia.

Insecticides are also in use, but generally only in urban locations with high-value trees. Current-ly, insecticides with active ingredients such as imidacloprid, emamectin ben-zoate, and dinote-furan are used since they are “systemic” (absorbed by the tree’s roots and be-come part of the tree) and will remain effective for up to three years, depending on the product used. The insecticides are either injected into the tree directly or absorbed as a soil drench. Some of the insecticides may only be applied by licensed applicators, and while initially the trees can handle the injections, after several applica-tions there is a toll on the trees’ health. And, for all that, EAB depredations can continue unabat-ed, even in the presence of these poisons. Insec-ticides are not considered effective in the treat-ment of forested areas infected with EAB.

There is much more that could be said about the EAB and the potential loss of an entire genus of trees in this country. Remembering the fate of the American chestnut and the elm trees that once seemed as if they would always be around in great numbers, gives urgency to those who are expending much effort to stop the destruc-tive slow march of Emerald Ash Borer.

The First Flight by Maryellen Farley

I love all birds, but if I had to choose my very favorite, it

would have to be the Eastern Bluebird. Several years ago, I purchased a decorative birdhouse from someone who made and sold them on a country road in Massachusetts. It was only $10.00, but worth its weight in gold. As soon as we hung it on a tree in our backyard, a male bluebird landed on top. It proved to be prime real estate. Shortly after,

his mate showed up and the contract was signed. The nest was built and life began. This year, tree swallows took over the decorative abode. The bluebirds were searching for a place to build their nest, but the tree swallows swooped and shooed them away consistently. In a panic, we ran out and purchased a bluebird box. Our yard is very small and there weren’t many choices on where to place it, so we put it on the edge of a flower bed. The tree swallows wanted to claim that house as well, but they lost their battle to house sparrows. That began my personal battle. I made it my mission to check the bluebird box and dismantle the sparrows’ nest every morning before I went to work. This occurred at least ten times. During this time I didn’t see the blue-

birds, so I assumed they built their nest else-where. My persistence paid off. The sparrows left and the bluebirds returned! Before we knew it, the female was busy transporting pieces of grass and getting ready to lay her eggs. Ironically, the day we attended “The Bird with the Sky on Its Back” presentation (July 18th) was the same day we saw the fledglings. We noticed the young birds were poking their beaks out of the house the evening before, so we thought they were getting ready for their first flight. We were right! Around 8:00 a.m. on July 18th, we saw the first fledgling make his way into the world. There is a Leyland Cypress within six feet of the bluebird house, but the fledgling went straight (instead of curving right into the tree) and landed on one of our patio chairs. The total distance was about ten feet. He hopped onto the patio, then onto a bistro table, and then clung to an umbrella. Mom was waiting in the Leyland Cypress. She called him and off he went. His brother tried to follow suit and headed for the patio as well, but Mom swooped down and guided him into the tree. There was a third fledgling that just wasn’t quite ready to leave the nest. It wasn’t crowded anymore, and he had the whole house to himself, so what was the hurry? Dad waited patiently on top of the house, keeping a careful lookout. At one point he went in to see what the problem

was. We didn’t see the last fledgling make his flight, but the house was empty by that after-noon. We figured the whole family had moved on since we hadn’t seen any of them for about two weeks. Then one evening (August 3rd), we no-ticed a male and female bluebird perched on top of the bluebird box. The male kept a watch-ful eye, while the female bathed in a large

planter dish in the garden. One young bluebird joined her and then another! The youngsters splashed so much that Mom took off. We learned that a bluebird family stays together until the young can fend for themselves. Brian and Marci Swanson from the Virginia Bluebird Society were able to answer all of our questions at the presentation that morning, which made this experience even more memorable. Timing really is everything!

Update: Audubon at Home Wildlife Sanctuary, Apartment Edition

by Maria Stewart

D o you still think it’s too difficult to get your garden certified as an Audubon at Home Wildlife Sanctuary? Well, you shouldn’t.

You may recall how, in the March 2015 Turnip News (http://goo.gl/yQmXrh), I described the series of events that left our third floor apartment balcony just two critters shy of the ten that the Audubon at Home Wildlife Sanctuary program requires for certifica-tion. You may also recall how I had not even been trying for certification.

And yet, certification was right around the corner with visits from Carolina Chickadees and a Carolina Wren - critters nine and ten!

So, what started with a half crispy, half wilted lemon cucumber is now an Audubon at Home Wildlife Sanctuary - on an eighteen square foot, third floor apartment balcony.

basil - We got a couple of harvests for ourselves, but now it’s a “load-bearing basil” for a very industrious spider. It’s gone to flower and the buzzing critters, including the hummingbirds, have been enjoying it.

Eastern box turtle - ok, he wasn’t on the balcony, but he was in the front of my building. So close!

mountain mint - A “must have” according to many Audubon at Home Ambas-sadors. It’s easy, native, and critters love it. I got mine courtesy of MG Maryellen Farley. I think it may need a bigger pot!

Get to Know a Critter: Damselfly

Blue-ringed Dancer (Argia sedula)

Did you know? ♦ The blue-ringed dancer damselfly is active in Virginia from June through October.

♦ Blue-ringed dancers live near rivers, streams, lakes, and ditches with aquatic vegetation. They often perch on vegetation in the shade, unlike most other dancers.

♦ Blue-ringed dancers are beneficial because they voraciously eat small insects, especially gnats and mosquitoes.

♦ The number of damselfly species in your landscape directly reflects the health of the surrounding streams, ponds, and wetlands.

♦ To promote damselfly health, plant a wildflower garden to attract insect prey. Also, create a mini-wetland water feature.
