Dogwood Borer
Larvae feed in the inner bark of live, healthy dogwood trees. The damaged area of the trunk or branch swells and eventually the bark will fall off. Leaves turning red prematurely in mid-summer on a lone branch are an early sign of dogwood borers. Infested branches and limbs will die. Dogwood borers often will not kill the tree in the first year, but reinfestation in successive years will. Plants attacked include: Dogwood, pecan, elm, hickory, and willow.

Cottony Maple Scale
Heavily infested plants will have large numbers of scales on the branches and twigs. Large numbers of feeding scales will reduce the amount of nutrients reaching the leaves and will cause them to turn yellow and fall prematurely. Scale insects feed on plant sap with their long thread-like mouthparts (stylets), which are six to eight times longer than the insect itself. Feeding by scales slowly reduces plant vigor. Heavily infested plants grow poorly and may suffer dieback of twigs and branches. Occasionally, an infested host will be so weakened that it will die.

Scale Insects
Scale insects are a peculiar group and look quite different from the typical insects we encounter day to day. Small, immobile, with no visible legs or antennae, they resemble individual fish scales pressed tightly against the plant on which they are feeding. There are over l50 different kinds of scales in Virginia. Many are common and serious pests of trees, shrubs, and indoor plants.

Catalpa Sphinx Caterpillar
Catalpa sphinx caterpillars, also known as “Catalpa worms”, are major defoliators of catalpa, their only host. With their chewing mouthparts, they strip away large portions of the leaves. In heavy infestations they can completely defoliate the entire tree. Apparently trees on high ground with poor soil are rarely, if ever, attacked. In some years, depending on the region, many trees will have all their leaves stripped away by the end of the summer. This may be followed by years with no defoliation observed at all. The fluctuation between outbreak and no defoliation is largely due to the activity of parasites.
Nov 14, 2014 2911-1421 (ENTO-88NP)
European Hornet
The European hornet is a stout hornet approximately 1-inch long. The color of the head and thorax is dark reddish brown with deep yellow and brown black markings on the abdomen. The markings on the abdomen are similar to the markings found on yellow jackets. The European hornet resembles the cicada killer wasp but is more robust and has more hair on the thorax and abdomen (but is not as hairy as a bee).
Mar 12, 2015 2911-1422 (ENTO-123NP)
Twig Girdler/Twig Pruner
These beetles cause very conspicuous damage in late summer. The leaves on large numbers of twigs and branches will be observed to turn brown prematurely. These twigs and branches sometimes fall from trees in great numbers and accumulate. On close examination, the twigs have one of two kinds of damage. Twigs damaged by the twig girdler are cut as neatly as by a knife. The cut end has been gnawed almost straight across with a faint rounding and is slightly roughened by the chewing. The twig girdler is more commonly found on pecan and hickory. The twig pruner causes a slightly different type of cut. The twig will be observed to have a hollowed out space at the cut end filled with sawdust like frass. The twig when split open will have a long tunnel through most of its length. The twig pruner is more commonly found on oak.

Pest Management for Water Quality
Research has shown that consumers find reading and understanding the label to be the most difficult aspect of applying pesticides. However, an understanding of the label information is essential before work begins. The label printed on or attached to a container of pesticide tells how to use it correctly and warns of any environmental or health safety measures to take. Read the label when you purchase a pesticide and again before mixing or applying it. If you are confused about any part of the label, consult your Extension agent or a representative of the company that makes the product. Many pesticides now list a toll-free number for consumers. The label includes specific information that you should be aware of and learn to understand.Diane Relf, Extension Specialist, Horticulture, Virginia Tech Reviewed by David Close, Consumer Horticulture and Master Gardener Specialist, Horticulture, Virginia Tech

Black Vine Weevil
The adults feed on a wide variety of evergreen, deciduous, and herbaceous plants. The larval form is destructive on yew (taxus), hemlock, rhododendron, and several other broad-leaved evergreens. Adults and larvae will sometimes feed on strawberry and impatiens.
Nov 14, 2014 444-210 (ENTO-86NP)
Longhorned Beetles/Roundheaded Borers
Size: Larvae up to 3 1/4 inches (80mm) or more. Color: Adult longhorned beetles are medium to large cylindrical beetles, usually brown, reddish brown, or black in color. They are sometimes mottled or banded with white or gray. Larvae (roundheaded borers) are brown, reddish brown, or black. They are sometimes mottled or banded with white or gray. Adults are called longhorned beetles because of their long and distinctive 11-segmented antennae, often longer than the beetle's body. The thorax and wing covers on some species bear small, stout spines. Roundheaded borers (larvae) are elongate, cylindrical, and have large gnawing mandibles. The name roundheaded borer refers to the enlarged thorax directly behind the head. Order: Coleoptera, Family: Cerambycidae.
Dec 11, 2014 444-215 (ENTO-100NP)
Bark Beetles
Species identification is difficult because the adult beetles of the various species are very similar, cylindrical and hard-shelled. Over 600 species in the sub-family. Adult beetles are between 1/8 and 1/3 inch long. Nearly all bark beetles are black or brown. Bark beetles are in the Order: Coleoptera, Family: Curculionidae, Sub Family: Scolytinae.
Nov 10, 2014 444-216 (ENTO-85NP)
Aphids
Aphids, or plant lice, are small, soft-bodied insects. There are hundreds of different species of aphids, some of which attack only one host plant while others attack numerous hosts. Most aphids are about 1/10 inch long (2.54 mm), and though green and black are the most common colors, they may be gray, brown, pink, red, yellow, or lavender. A characteristic common to all is the presence of two tubes, called cornicles, on the back ends of their bodies. The cornicles secrete defensive substances. In some species they are quite long, while in others they are very short and difficult to see. Aphids feed in clusters and generally prefer new, succulent shoots or young leaves. Some species, known as wooly aphids, are covered with white, waxy filaments, which they produce from special glands. Order: Homoptera, Family: Aphididae
Nov 3, 2014 444-220 (ENTO-82NP)
Spider Mites
Spider mites (Family Tetranychidae, Order Acari) are not insects; they are closely related to spiders, harvestmen (daddy longlegs), and ticks. Unlike insects, which have six legs and three body parts, spider mites have eight legs and a one-part body. They also lack wings, antennae, and compound eyes. Individual spider mites are almost microscopic, yet when they occur in large numbers, they can cause serious damage. Dozens of species attack shade trees, shrubs, and herbaceous plants.
Feb 26, 2015 444-221 (ENTO-107NP)
Spruce Spider Mite
The spruce spider mite (Acari: Tetranychidae, Oligonychus unuguis (Jacobi)) lives in all areas of Virginia and is widely distributed throughout the temperate regions of the United States and Canada. It attacks spruce, arborvitae, juniper, hemlock, pine, Douglas fir, Fraser fir, and larch, among others.
Mar 2, 2015 444-235 (ENTO-108NP)

Multicolored Asian Lady Beetle in Virginia
Multicolored Asian Lady beetles enter the house through small openings around windows, doors, and utility access points. In addition, they can enter the house by cracks in the siding and trim and through attic vents. Sealing those entry sites is the best method to keep them from becoming indoor pests later. Conduct a thorough energy audit of your house, as places where cold air can enter the house are places where this lady beetle can gain access. Fill all cracks and leaks with a fine quality silicone or silicone-latex caulk. Once inside, insecticides are not recommended except for severe cases. Sweep up with a broom and dustpan all beetles that collect in windowsills and on walls. Beetles can also be picked up with a vacuum cleaner but bags will need to be discarded so that beetles do not escape.
Dec 11, 2014 444-275 (ENTO-102NP)
Periodical Cicada
In Virginia both the 17-and 13-year cicadas damage many ornamental and hardwood trees. Oaks are commonly attacked but the most seriously damaged are newly planted fruit and ornamental trees such as apple, dogwood, peach, hickory, cherry, and pear. Pines and other conifers are not commonly attacked.
Feb 25, 2015 444-276 (ENTO-105NP)
Euonymus Scale
Eggs are laid early in the spring and hatch in late May or early June. The crawlers settle quickly and produce a second brood by mid-July. A third brood is produced in October. There is continuous overlapping of broods, so that all stages may be found during favorable conditions. Two to three-plus generations per year may occur in Virginia. The overwintering stage is the adult female.

Thrips
Adult thrips are small, pale-yellow insects (occasionally black) with elongated bodies, and fringed wings. Their life cycle consists of an egg, nymph, pre-pupa, pupa and an adult. The exact time required for thrips to complete their life cycle varies with species, temperature and the host plant. Western flower thrips complete their life cycle, from egg to adult, in approximately 10 days at 80° F. Adults insert eggs in leaf tissue which hatch in approximately three days. Nymphs feed for four to five days and then drop from the plant to pupate in the soil. Adults emerge after two days of pupation and begin feeding.

Galls made by aphids, adelgids, phylloxerans, psyllids, and midges
Galls made by made by aphids, adelgids, phylloxerans, psyllids, and midges occur on many different plants. Galls are abnormal growths of plant tissue induced by insects and other organisms. Gall-making parasites release growth-regulating chemicals as they feed, causing adjacent plant tissues to form a gall. The parasite then develops within the relative security of the gall. Most are harmless to trees, but a few are pests.

Improving Pest Management with Farmscaping
Farmscaping is a holistic ecologically-based approach to pest management that emphasizes the arrangement or configuration of plants that promote biological pest management by attracting and sustaining beneficial organisms. Ideal farmscape plantings provide habitat for beneficial insects, suppress weeds, and grow in close proximity to the cash crop without competing for light, water and nutrients. Research has shown that maintaining high levels of species diversity is a key characteristic of a proper functioning agroecosystem. Unfortunately, intensive farming operations including growing large monocultures, regular cultivation, and excessive use of insecticides often leads to a dramatic reduction in arthropod diversity, especially natural enemies that often keep many pest insects below damaging levels. Farmscaping is a technique designed to add diversity back to the system and minimize disturbance leading to increases in natural enemy populations by providing insectary plants as food and shelter resources.

Leatherwing (Soldier) Beetles
Beetles in the family Cantharidae are referred to as soldier beetles or leatherwings. The name soldier beetle originates from the elytra (front wings) of one of the earliest described species being reminiscent of early uniforms of British soldiers. The latter name was coined for the soft nature of the elytra. Two species in the genus Chauliognathus are commonly found in Virginia. Chauliognathus pennsylvanicus (Fig 1) is often referred to as the Pennsylvania leatherwing, or the goldenrod soldier beetle referring to its favorite flowering plant in the fall. A similar species Chauliognathus marginatus, the margined leatherwing, is found in the spring on various flowers.

History, Distribution and Pest Status of the Mexican bean beetle
Mexican Bean Beetle (MBB), Epilachna varivestis Mulsant, (Fig 1) is an herbivorous ladybeetle (Coccinellidae) that feeds on legumes in North America. It is closely related to the squash ladybeetle, Epilachna borealis, which feeds primarily on cucurbits. MBB can cause significant defoliation damage to bean crops, particularly those in the genus Phaseolus (snap beans, lima beans, pole beans, etc.). For more information on general biology and pest management of MBB, see VCE Fact Sheet No. ENTO-51.

Pepper Weevil
The pepper weevil, Anthonomus eugenii (Cano), is a sporadic pest of pepper in Virginia. The insect is predominately a pest in the southern U.S., where it can inflict significant damage to that crop. Though adult weevils may feed on numerous plant species within the family Solanaceae, oviposition and subsequent larval development is specific to plants within the genera Capsicum (peppers) and Solanum (nightshades). Individuals may live 3-4 months and there are multiple generations (often 5-8) per year. The pepper weevil is an uncommon pest in Virginia, but if it occurs, infestations can result in the loss of entire pepper crops.

Squash Bug
Squash bugs are one of the primary pests of cucurbits in the United States. Adults are typically 10 to 30 mm long, dark gray, brown or black in color with orange or brown markings on the sides of the abdomen (Fig. 1). Overwintering adults emerge from the soil, ground litter, wood piles or buildings in the spring. After feeding and mating, females deposit egg masses on the underside of leaves. Newly laid eggs are typically light pale in color, become coppery, then darker as they develop. Egg masses are commonly laid in diamond or V-shaped patterns along leaf veins (Fig 2).

Food Safety For School and Community Gardens
Creating and maintaining community and school gardens has been identified as an effective strategy to increase healthy food awareness and consumption. Unfortunately, fresh fruits and vegetables have been linked to more than 450 outbreaks of foodborne illness in the U.S. since 1990. In commercial food production, employing a set of risk-reduction steps — known as good agricultural practices (GAPs) — has been pointed to by the U.S. Food and Drug Administration as the best prevention against foodborne, illness-causing pathogens.

Emerald Ash Borer
The emerald ash borer (Agrilus planipennis Fairmaire) is a wood-boring beetle native to eastern Asia and is now considered the most destructive forest pest ever seen in North America. Since its discovery in Michigan in 2002, it has killed tens of millions of native ash (Fraxinus spp.) trees in the United States and Canada. This destruction has already cost municipalities, property owners, and businesses tens of millions of dollars in damages.
