APPENDIX - ADDITIONAL WEBSITE RESOURCES.

1. PLANTS OF THE WEEK. *ANNUAL - SNAPDRAGON (Antirrhinum majus).

There are over 40 species of this underused plant. The snapdragons' bright and showy lavender, red, yellow, violet or white flowers make a colorful splash in the garden throughout the summer. It grows from 1-3' tall. The shorter mound-type varieties are used as bedding plants, intermediates (15-24") require no stakes and therefore make good border plants, and the tall columnar snapdragons are best for cuttings.

The snapdragon does well in moist, fertile, well-drained soil. It needs full sun and good air circulation at the base of the plant. Small types can be spaced 6" apart; larger varieties should be staked 12" apart. Remove the faded flower spikes.

*PERENNIAL - HOSTA (Hosta spp.).

Hostas are extremely popular and hardy herbaceous perennials grown primarily for their beautiful foliage. There are up to 45 species of these plants, which originally came from Japan, China and Korea. They were first introduced to Europe in the late 1700s and then came to the United States in the middle 1800s.

Hostas are easy to grow and are adapted for shade-environments. Their leaves come in a wide range of shapes, colors, sizes, and textures and may be solid in color or variegated in different combinations of blue, green, white, and gold. The plants are low maintenance and are widely available in nurseries and garden centers. Many catalogs also offer a large selection of hostas, with more than 2,500 different cultivars on the market. For more information on hostas, see OSU Extension FactSheet HYG-1239-02, "Growing Hostas" http://ohioline.osu.edu/hyg-fact/1000/1239.html .

OSUE FactSheet HYG-1239-02

*WOODY - HIGHBUSH BLUEBERRY (Vaccinium corymbosum).

Highbush blueberries can be wonderful landscape plants. They have a multitude of attractive white flowers in the spring, wonderful foliage in many shapes and shades of green, showy and nutritious fruits in various hues of blue with many flavors - tasty fruit for humans and wildlife alike, brilliant scarlet foliage in the fall, and many interesting growth habits that can provide winter interest.

There are many cultivars of this native North American plant, which vary greatly in fruiting time, growth habit, berry color, and taste. Highbush blueberries grow 6-12' tall and require full sun to optimize growth and production. Like other Ericaceous plants, blueberries require a high organic matter soil with a low pH (4.5-5.5). Highbush blueberry is self-fertile, but cross-pollination increases fruit set and results in larger, earlier berries with more seeds.

Highbush blueberries will not tolerate competition from other plants. It is essential that they be kept weed free and well mulched. It has been found that a mulch of 4-6" of fresh hardwood sawdust will work extremely well - this type of mulching is not recommended for almost any other plant. For further information on highbush blueberries refer to OSU Extension Bulletin 940, "Midwest Home Fruit Production Guide" http://ohioline.osu.edu/b940/index.html and USDA/NRCS Plant Fact Sheet, "Highbush Blueberry" http://plants.usda.gov/factsheet/pdf/fs_vaco.pdf

USDA/NRCS Plant Fact Sheet, "Highbush Blueberry" OSU Extension Bulletin 940, "Midwest Home Fruit Production Guide"

*WEED - COMMON POKEWEED (Phytolacca Americana).

Common pokeweed is native to the eastern half of the US. This species appears to be widespread in Ohio and is continuing to invade reduced-tillage fields. Common pokeweed prefers low, rich, somewhat disturbed, gravelly soils, and can be found in pastures, roadsides, fencerows, open woods and wood borders. It is a large, bushy, herbaceous perennial that sometimes resembles a small tree, growing up to 10' in height. The plant is characterized by an enormous taproot, smooth succulent red- purple stems, large lance-shaped leaves and grape-like clusters of dark purple berries in the fall. It reproduces from seeds.

All parts of common pokeweed are toxic to humans, pets and livestock. Roots are the most poisonous, leaves and stems are intermediate in toxicity (toxicity increases with maturity), and berries are the least toxic. Since common pokeweed is not very palatable, most animals avoid eating it unless little else is available, or if it is in contaminated hay. Horses, sheep and cattle have been poisoned by eating fresh leaves or green fodder, and pigs have been poisoned by eating the roots. Children are most frequently poisoned by eating raw berries. Infants are especially sensitive and have died from eating only a few raw berries. Although boiled young shoots have been eaten as greens and berries cooked in pie, ingestion of any part of the plant cannot be recommended. Adults have been poisoned, sometimes fatally, by eating improperly prepared leaves and shoots, especially if part of the root is harvested with the shoot, and by mistaking the root for an edible tuber. Research with humans has also shown that common pokeweed can cause mutations (possibly leading to cancer) and birth defects. Since the juice of pokeweed can be absorbed through the skin, contact of plant parts with bare skin should be avoided. For more information on this plant, refer to "Ohio Perennial & Biennial Weed Guide" http://www.oardc.ohio- state.edu/weedguide/singlerecord.asp?id=270 .

2. HORT SHORTS. A. ROBBERS ON THE WING.

Joe Boggs reported that he has received several e-mail messages and phone calls about ROBBER FLIES (family Asilidae). There are over a thousand species of robber flies in North America representing a wide range of forms and sizes. The largest sized species found in Ohio is the scary-looking (and named!) RED-FOOTED CANNIBALFLY (Promachus rufipes) which can measure over 1 1/4" long. The cannibalfly makes a loud buzzing sound as it flies and alert observers may hear the buzz punctuated by a very loud "snap" which means the fly has committed an insecticidal act!

Cannibalflies have narrow bodies and long, dangling legs. Their stout thorax appears slightly humped when viewed in profile. Each leg is tipped with two formidable tarsal claws that function like grappling hooks. In a smashing display of aerial acrobatics, the fly slams into its airborne quarry which stuns the hapless insect victim. The high-speed collision produces a snapping sound that may be heard several feet away. The fly then grasps its dazed prey with its claws, and uses its piercing-sucking mouthparts to inject saliva containing neurotoxic and proteolytic enzymes. The enzymes paralyze the victim and digest the internal tissues. The fly then lands, and sips the life out of its victim.

Adults of all species of robber flies are predators and they will attack a variety of insects including bees, wasps, grasshoppers, dragonflies, damselflies, and sometimes each other. They often seize prey that is much larger than their own body size. Their larvae are also predaceous and live in the soil, or in decaying wood and other organic matter, where they feed on insect larvae. Thus, both the adults and larvae rob insects of their lives.

B. CAPTIVATING ORBWEAVERS.

Travelers in Ohio may be treated to the beautiful early morning view of dew-covered orbweaver webs shimmering in fields along roadways. The round ("orb") webs consist of radiating spokes of non-sticky silk overlaid with a spiraling thread of sticky silk. Three of the more common orbweaver spiders (Family Araneidae) currently on display in Ohio are the large BLACK-AND-YELLOW ARGIOPE (Argiope aurantia), the tiny TRASHLINE SPIDER (Cyclosa turbinate), and the medium-sized BARN SPIDER (Araneus cavaticus).

The black-and-yellow Argiope is one of the largest orbweavers found in Ohio; females often measure over to 2" from the tips of their legs. The spider sports black legs, a yellowish-silver cephalothorax, and a black abdomen with intricate bright yellow to golden-yellow markings. Their markings and web locations engender a number of monikers including: yellow garden Argiope, yellow Argiope, golden orbweaver, yellow garden orbweaver, and golden garden spider. The spider produces a vertical structure of dense, coarse silk at the center of its web known as a "stabilimentum," and the zigzag pattern of the stabilimentum gives rise to the names "zigzag spider," and "writing spider." Webs are often built at "face height" leading to close, entangling encounters with this spider inducing more colorful names spun together with expletives.

Entomologists were once puzzled as to how such a large, brightly colored spider hanging in the center of its web in the middle of the day could be so successful in capturing insects in their web. It would be like sheep running to wolves. The answer rests with understanding insect vision. Insects are capable of seeing ultraviolet light in wavelengths that are invisible to humans, and certain flowers that appear white to people actually reflect intricate patterns of ultraviolet light, presumably to attract insects. Research has shown that when Argiope spiders and their webs are viewed under ultraviolet light; the spider disappears, the web disappears, but the zigzag stabilimentum blazes like a giant neon "eat here" sign. Insects are lured to their doom thinking they are visiting the mother of all flowers!

Trashline spiders are relatively small measuring around 1/4-1/2" from the tips of their legs. Their legs, cephalothorax, and abdomen are covered with mottled black and white markings. These spiders also construct a vertical stabilimentum of coarse silk in the center of their webs. A close examination of the stabilimentum will reveal that the silk enshrouds the drained bodies of previous victims; the morbid structure is responsible for the "trashline" common name. The spiders rest in the middle of their trashline and their mottled coloration makes them very difficult to see among their similarly sized and colored bundles of trash. Indeed, research has shown that the trash bundles serve to confuse predators, such as birds and wasps, intent on making a meal of the spider, and the greater the number of bundles, the greater the confusion.

Barn spiders are medium-sized round spiders measuring 1/2-3/4" from the tips of their legs. The top of the abdomen as well as their legs and cephalothorax are covered with mottled light brown to black markings. The spiders have a very distinct marking on the underside of their abdomen that is pitch-black with two yellowish-white marks along the edge of the black background. Barn spiders are nocturnal. They construct their orb webs each evening, and then they consume their webs in the morning. This spider is often encountered in doorways in the morning, hanging where there was no spider the day before.

C. NUISANCE WILDLIFE MANAGEMENT WEBSITES.

BYGLers routinely get numerous calls about rabbits, raccoons, deer, squirrels, geese, and other critters damaging plants and structures and otherwise making a nuisance of themselves. Many Ohio residents are aware of the very good Ohio Department of Natural Resources (ODNR) web site, Nuisance Wildlife: Preventing and Dealing with Encounters http://www.dnr.state.oh.us/Home/wild_resourcessubhomepage/dealing_with_wildlifeplaceholder/NuisanceSpecieslandingpage/terrestrialnuisancewildlife/tabid/5674/Default.aspx .

The ODNR site is highly recommended. However, few are aware of another very useful site, the Internet Center for Wildlife Damage Management http://icwdm.org/Default.asp, which is a collaborative of Cornell University, Clemson University, University of Nebraska - Lincoln, and Utah State University It is a non-profit, grant funded site that provides research-based information on how to responsibly handle wildlife damage problems. Check it out!

3. BUG BYTES. A. BALDCYPRESS TWIG GALL.

Participants in last week's Diagnostic Walk-Abouts in southwest Ohio observed the galling handiwork of Taxodiomyia cupressiananassa, a tiny midge fly with a large scientific name. The spongy, elongate, 1/8-1/2" long galls produced by the fly appear white due to a covering of fine, powdery material. Rubbing the powder off the galls reveals their true light green color. The common name "twig gall" is technically inaccurate since the galls actually arise from the base of leaflets. Needle growth extends through the galls with the needles protruding beyond the surface of the galls and a portion of this season's growth usually extends beyond the tips of the galls.

Opening the galls will reveal the tiny, orangish-yellow midge fly larvae (maggots) that directed gall formation. Each maggot is individually housed in its own tiny compartment. Once maggots pupate, and a new set of adults emerge, the galls will eventually shrivel and detach from the trees. At this time, the leaflet growth extending beyond the gall will sometimes die and turn reddish brown producing an unsightly appearance. Adult flies emerge from the fallen galls on the ground.

The flies may have two generations per year with a second set of galls appearing in late-July or August. The second generation gall-makers spend the winter on the ground as pupae in fallen galls. Although the galls and browned-tipped foliage may reduce the aesthetic appeal of infested trees, the flies appear to cause no appreciable harm to the health of the tree. Populations are often regulated by a wide range of parasitoids that target the maggots. Therefore, insecticide applications are not recommended. Pruning and destroying galls now on small trees will reduce the number of future galls.

B. NET-WINGED BEETLES.

This is time of the year when one of the more unusually looking beetles begins to appear in Ohio landscapes and forests; these are the NET-WINGED BEETLES (Family Lycidae). The front wings (elytra) on most beetles are hardened and they cover and protect the hind wings and abdomen. Indeed, the name of the beetle order, "Coleoptera," clearly describes this arrangement (coleo = sheath; ptera = wing). However, net-winged beetles have soft, leathery elytra. Their common name comes from the network of raised longitudinal and transverse ridges on the elytra that resemble netting.

There are around 50 species of net-winged beetles in North America. The two most common species found in Ohio are the banded net-winged beetle, Calopteron reticulatum, and the end-banded net-winged beetle, C. terminale. Both are medium- sized (about 5/8" long), elongate, slightly flattened beetles, with elytra that are widened towards the posterior end. The pronotum (segment behind the head) of both beetles is black with yellow margins, and the elytra are orange to yellowish-orange with the hind portion black. The banded net-wing has a narrow black band crossing the front of the elytra.

The beetles contain pyrazines that give the beetles a repugnant scent. They also contain lycidic acid and other fatty acids that may impart a foul taste if the beetles are consumed by a predator. It is speculated that their bright coloration is provides a warning to predators that these beetles are not good to eat. Adults are active during the day and they feed on decaying plant material, and occasionally on other insects. The larvae are predaceous and consume a wide range of prey including insects, slugs, sowbugs, and millipedes. Thus, net-winged beetles are considered beneficial insects.

University of Florida Entomology Featured Creatures Fact Sheet

C. WINDSHIELD WIPES.

BYGLers also ran into a number of other insect pests this week including:

*The COMMON BAGWORM (Thyridopteryx ephemeraeformis) feeding season is coming to an end. Joe Boggs reported that around fifty percent of the bagworm caterpillars in the Cincinnati area have tied the feeding end of their bags to anchorage points and sealed the opening closed to prepare to pupate. This means the time to treat with an insecticide to manage bagworm populations has come to an end. Hand-picking bags from host plants is the only effective management option available at this time.

Joe also reported finding second generation DUSKY BIRCH SAWFLY (Croesus latitarsus) larvae on several small river birch trees in southwest Ohio. He noted that feeding damage caused by both the first and second generations was very obvious. Early instar larvae are dark gray, middle-instars are greenish-gray, and late instars are yellowish-green. All instars have shiny black head capsules and distinct black spots on their bodies. Larvae feed in colonies, lined up head to tail along leaf margins. When disturbed, the larvae form their bodies into a distinct "S" shape (S for sawfly?). Early instar larvae consume all but the mid-veins and main lateral veins while late instars consume entire leaves. There are two generations of this sawfly in Ohio.

4. DISEASE DIGEST. A. JUNK IN THE BOX.

Nancy Taylor of the C. Wayne Ellet Plant and Pest Diagnostic Clinic wants to remind BYGLers and readers alike that diagnostics can sometimes be very difficult to perform even on the best of samples, but can be made extremely difficult to impossible when poor samples with no supporting information are submitted. Extremely poor samples will be given extremely low priority when they arrive at the clinic. This is a necessity as the clinic is currently very short-handed. Even when the clinic is not short-handed, sending poor samples is extremely poor etiquette and will likely not produce any results. To put the poor sample scenario into perspective, one should think of how one interacts with a medical doctor for diagnosing a personal illness. As Jim Chatfield had mused, "Would one clip off a finger nail, send it to the doctor's office and expect a complete, thorough diagnosis of what is wrong with the rest of the body?" It is the same for plant problem diagnosis. Minute samples of a single leaf or a few dead twigs will tell next to nothing about the condition of a plant. It is equally important to send supporting documents to go along with the sample.

To assist all in taking good samples, the clinic's web page provides instructions on how to take good samples and provides submission forms to collect supporting data. The clinic's web page is found at http://ppdc.osu.edu/ .

5. TURF TIPS. A. CHINCH BUGS ARISE.

Second generation HAIRY CHINCH BUGS (Blissus leucopterus) are active in turfgrass in southwest Ohio. Chinch bug damage usually appears as browned turf occurring in irregular patterns and the symptoms may be mistaken for high temperature dormancy, drought stress, or even certain turfgrass diseases.

Chinch bug infestations cannot be identified using drive-by diagnostics. A proper identification requires an up-close and personal inspection on bended knee. Parting the grass will reveal the chinch bug adults and nymphs darting about among the turfgrass stems. If the grass is becoming off-colored, look closely at the exact color. Chinch bugs inject toxins into stems as they feed causing the blades to first turn a purplish color rather than the straw-brown color associated with drought stress.

Chinch bug management strategies may include short-term suppression using insecticide applications, or long-term suppression through plant selection. Effective curative insecticides include: bifenthrin (e.g. Talstar); lambda-cyhalothrin (e.g. Scimitar); and deltamethrin (e.g. DeltaGard). For clients who desire a more "organic" approach, university research studies have shown that azadirachtin (e.g. Azatrol) provides about 80% control with one application and nearly 100% control with two applications made 10 to 14 days apart.

Lawns with a long history of chinch bug outbreaks are good candidates for using turfgrass selection to suppress chinch bug populations. Certain cultivars of turf-type tall fescue and perennial ryegrass are known to harbor endophytic fungi. These fungi reside between plant cells within the turfgrass blades (= endo) where they enjoy a symbiotic relationship with the turfgrass plants. The fungi live off waste products exuded by plant cells. In return, the fungi protect turf plants by producing alkaloid compounds that are toxic to top-feeding insects, including chinch bugs. Over-seeding with "endophyte enhanced" turfgrass cultivars will provide a long-term solution to chinch bug problems.

6. INDUSTRY INSIGHTS. A. ASIAN LONGHORNED BEETLE (ALB) UPDATE - A TIME OF TRANSITION.

The United States Department of Agriculture/Animal Plant and Health Inspection Service's (USDA/APHIS) Incident Command Team has returned to their regular positions. Others have come in to serve on a temporary assignment and the Ohio Department of Agriculture (ODA) is in the process of hiring personnel to work on the ALB project in Clermont County. During this time of transition, they continue to survey trees in the immediate area, urge people to look at their own trees and report any suspicious trees, and are awaiting comments on the ALB Ohio Environmental Assessment. More numbers to come soon!

USDA/APHIS Official Website - Beetle Busters ODA ALB Webpage

B. MAGNOLIA SCALE CRAWLS.

Joe Boggs reported that the reddish-brown first instar nymphs (= crawlers) of MAGNOLIA SCALE (Neolecanium cornuparvum) are becoming numerous enough to be easy to spot on the stems of infested host trees in southwest Ohio. This is one of the largest "soft scales" in the state with mature females measuring as much as 1/2" in diameter. The helmet-shaped females are brownish- purple and can be found attached to the twigs, branches, and main stems of their namesake host as well as tuliptree. The scale uses its sucking mouthparts to extract sap from phloem vessels. Heavy infestations can kill branches, or even entire trees, or produce enough physiological stress to make trees susceptible to succumbing to other problems.

Magnolia scale is also notorious for exuding copious quantities of "honeydew." The sticky honeydew may drip onto the leaves and stems of the host plant as well as plants beneath an infested tree, or onto sidewalks, cars, slow-moving gardeners, etc. Honeydew is often colonized by black sooty molds and while the molds do not harm plants, the sticky goo combined with the molds can produce an unsightly mess. Of course, the occurrence of honeydew and sooty molds do not necessarily mean soft scales are afoot. Many other sucking insects (aphids, planthoppers, etc.) also exude honeydew.

Magnolia scale eggs remain inside the female's body until the eggs hatch which gives the appearance that the females are "giving birth" to live young. Egg hatch may occur continuously from early August into early October. This presents a serious challenge to the traditional approach to scale management which focuses on targeting the unprotected crawlers with topical insecticide applications. The extended egg hatch means multiple applications are required to kill all of the crawlers produced this season. Neonicotinoid systemic insecticides are an effective alternative with control being achieved in a single application. A soil drench application of imidacloprid (e.g. Merit), dinotefuran (e.g. Safari), or clothianidin (e.g. Arena) from September into November will suppress this scale.
