|Potato Aphid on Tomatoes||Mar 29, 2019||2901-1031 (ENTO-308NP)|
The Japanese beetle is found throughout Virginia and in most of the Eastern United States. In regions west of the Mississippi it is found in isolated pockets. Japanese beetles were first found in New Jersey in 1916 and have spread from that point since. The Japanese beetle has been well established in Virginia since the early 1970’s.
|Sep 2, 2022||2902-1101 (ENTO-514NP)|
Pales weevil feeds on all pines within its range. It will also feed, although to a lesser extent, on Douglas-fir, fir, hemlock, juniper, larch, northern white-cedar, and spruce.

|Common Ticks of Virginia||Jan 30, 2022||2906-1396 (ENTO-487NP)|
Pine Sawyers are secondary infesters whose main damage is disfiguring wood by larval boring and tunneling in felled trees and usable trees which are weakened or dying from other causes. Plant parts attacked trunk. Damaging stage - larvae.
|Jun 9, 2020||2907-1399 (ENTO-372NP)|
|Pine Needle Scale||
Damage is not apparent until large populations have been present for more than 1 or 2 seasons. Trees are stunted, grow slowly, have short needles and shoots. Occasionally the feeding of scales produces chlorotic, yellowish flecks no the needles, but normally this is not apparent. Heavily infested plants are seriously weakened and may be in a state of decline.
|May 1, 2020||2907-1400 (ENTO-371NP)|
|Balsam Twig Aphid||
Twisted and curled needles are the most apparent damage from feeding by the balsam twig aphid. Feeding can also cause roughened bark on the twigs. Extensive feeding can cause a general decline and reduced vigor of the tree, yet in many cases is cosmetic and not particularly damaging. The major problem is that curled needles reduce the marketability and value of Christmas trees. Balsam twig aphids also produce honeydew, a sticky material that drops to needles and twigs below. At times the honeydew can become a growth medium for sooty mold, which turns the needles and twigs black.
|Apr 30, 2020||2907-1401 (ENTO-367NP)|
|Pine Bark Adelgid||
The pine bark adelgid was introduced from Europe and is now widely distributed in North America, occurring principally throughout the native range of eastern white pine. This insect is also found on Scots and Austrian pine.
|Mar 30, 2023||2907-1402 (ENTO-544NP)|
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).
|May 1, 2020||2911-1422 (ENTO-369NP)|
|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.
|May 1, 2020||2911-1423 (ENTO-374NP)|
|Virginia Pine Sawfly||
The Virginia pine sawfly has been recorded from New Jersey and Maryland to North Carolina and westward to Illinois. Its main hosts are Virginia and shortleaf pines, but it also feeds on pitch and loblolly pine.
|May 1, 2020||2911-1424 (ENTO-375NP)|
|The Minute Pirate Bug (Orius)||Mar 18, 2019||3002-1437|
The baldfaced hornet is a large, black and white hornet up to 1 inch (25.4mm) in length. It is black and white in color with a mostly white head or face. It is widely distributed in Virginia. The nests are constructed of the same paper-like material as that of other wasps (yellowjackets). They differ a great deal from other wasp nests in being enclosed in a thick "paper" envelope. There is a single opening at the lower end of the nest and a few hornets always guard this. Nests are always abandoned at the end of the season. Hymenoptera, Vespidae: Dolichovespula maculata (L.)
|Mar 6, 2020||3006-1449 (ENTO-352NP)|
|Hemlock Woolly Adelgid||Jul 13, 2022||3006-1451 (ENTO-228NP)|
|Balsam Woolly Adelgid||
Native to central Europe, the balsam woolly adelgid is now distributed throughout eastern and western North America. It attacks all true firs, Abies spp., including balsam and Fraser fir.
|Mar 1, 2021||3006-1452 (ENTO-434NP)|
The redheaded pine sawfly occurs from S.E. Canada throughout the eastern U.S. Feeding is primarily restricted to the two and three-needled pines, such as Jack, red, shortleaf, loblolly, slash, longleaf, and pitch pines. White pine and Norway spruce may also be defoliated.

Adults are usually black or brown beetles with an oval to oblong shape. They have clubbed or knobbed antennae and the economically important species typically measure 3–6 mm (0.12–0.24 inch) long. Some sap beetles have short wing covers that do not cover the entire abdomen. Some species have flattened bodies while others are more convex. Many sap beetles are a dull color, sometimes with mottling or spots. One common sap beetle, the picnic beetle [Glischrochilus quadrisignatus (Say)], is an attractive shiny black beetle with four yellow-orange bands or spots on the wing covers.

Adult rhubarb curculios are elongated, somewhat cylindrical beetles measuring about 13-19 mm (0.5-0.75 inch) in total body length. They have an obvious long snout that curves downwards from the head. Young adults have a dusty coating of yellow or orange powder that rubs off easily. Older beetles that have lost this dusty coating appear brownish-black in color. Mature larvae are legless white grubs with a brown head capsule. Rhubarb curculio larvae are only found in weedy hosts and not in rhubarb itself. There are a number of related, similar-looking weevils that occur on various weeds in the Asteraceae and Polygonaceae families.

|Squash Vine Borer||
Adult squash vine borers are robust, attractive moths with dark wings and conspicuous orange abdomens dotted with black spots. The legs are marked with orange, black, and white, and the hind legs are noticeably feathery. Adults measure about 13 mm (0.5 inch) long with a wingspan of about 32 mm (1.25 inches). The dark wings are held folded at rest; there is a short fringe of hairs on the trailing edge. Squash vine borer is a member of the clearwing moth family; translucent windows are visible in the hind wings when they are fully extended. The antennae are dark, somewhat flattened, and hooked at the tips. Overall, adult squash vine borers resemble paper wasps in appearance. They are active day fliers with a zig-zag flight and easily travel from field to field.

|Stalk Borer||Dec 22, 2021||3104-1567 (ENTO-477NP)|
|Tarnished Plant Bug||Apr 25, 2011||3104-1568|
Adult weevils are a dull, gray-brown color, and about 6–8 mm (0.25–0.32 inch) long. Adults are somewhat bristly in appearance due to t stout hairs and dense scales on the body. Usually there is a set of dark diagonal markings framing a lighter colored V-shape on the wings, but these may wear off with age. Antennae are elbowed and there is a short, stout snout at the front of the head.

|Whitefringed Beetles||May 6, 2020||3104-1571 (ENTO-379NP)|
Carpenter ants can be found outside on trees and sidewalks and indoor. Where they are found determines how best to control them. Inside they can be active indoors during many months of the year, usually during the spring and summer. When ants are active in the house during late winter/early spring (February/March), the infestation (nest) is probably within the household. In late spring large numbers of foraging ants may come in from outside looking for food and may not indicate and infestation. Outside carpenter ants become active in late spring and early summer and will be seen on tree trunks and sidewalks.

|Droplet Chart / Selection Guide||
When choosing nozzles/droplet sizes for spray applications, applicators must consider both coverage needed and drift potential. As a rule, smaller droplets provide better coverage, but larger droplets are less likely to drift.
|Aug 13, 2019||442-031 (BSE-263P)|
|Nozzles: Selection and Sizing||
This fact sheet covers nozzle description, recommended use for common nozzle types, and orifice sizing for agricultural and turf sprayers. Proper selection of a nozzle type and size is essential for correct and accurate pesticide application. The nozzle is a major factor in determining the amount of spray applied to an area, uniformity of application, coverage obtained on the target surface, and amount of potential drift.

|Plumbing Systems of Agricultural Sprayers||
The plumbing systems of agricultural sprayers are usually considered foolproof. Sprayer problems may occur if plumbing and/or modifications are improperly done or maintenance is ignored. Retrofitting, addition of electrical control systems, and replacement of pumps or nozzles require proper knowledge of the plumbing system and the implications of these changes to sprayer performance. Routine maintenance of the plumbing system is essential.

|Giant Resin Bee||
Size: about 0.75 inch (1.9 cm) Color: Black and yellow-brown Giant resin bees are large with a cylindrical body and large jaws. They have a dark head and abdomen with yellow-brown hair on the face, thorax, and the first segment of the abdomen behind the "waist." The wings are a transparent brown color that darkens toward the tips. Male giant resin bees have a truncated, squared abdomen while the females have a more tapered, pointed abdomen. Giant resin bees can be distinguished from bumblebees and carpenter bees by their cylindrical bodies and the appearance of their abdomens. Giant resin bees do not have hairy abdomens like bumblebees, nor are their abdomens shiny like carpenter bees. Hymenoptera: Megachilidae Megachile sculpturalis Smith.
|Mar 19, 2020||444-206 (ENTO-358NP)|
|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.
|Mar 6, 2020||444-210 (ENTO-354NP)|
|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.
|Mar 19, 2020||444-215 (ENTO-363NP)|
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.
|Mar 19, 2020||444-216 (ENTO-353NP)|
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
|Mar 4, 2020||444-220 (ENTO-350NP)|
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.

|White Pine Weevil||
The white pine weevil (WPW) (Coleoptera: Curculionidae, Pissodes strobi (Peck)) is found throughout Virginia. Its preferred hosts are eastern white pine and Norway spruce, but it can attack Scotch and other pines as well.
|May 6, 2020||444-270 (ENTO-377NP)|
|Eastern Tent Caterpillar||
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.
|Mar 6, 2020||444-274 (ENTO-356NP)|
|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.
|Mar 17, 2020||444-275 (ENTO-361NP)|
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.

Whiteflies are white insects with pale yellow bodies that are approximately 2 mm long. They belong to the order Homoptera and are close relatives of aphids, scales, mealybugs, hoppers and cicadas.
|May 6, 2020||444-280 (ENTO-378NP)|
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.

|The Peanut Southern Corn Rootworm Advisory||
The southern corn rootworm (SCR) has long been considered a major pest of peanuts in North Carolina and Virginia. However, researchers and Extension faculty at Virginia Tech and NC State have determined through more than 400 commercial field trials that the majority of peanut fields do not need to be treated. They have developed and tested a simple-to-use advisory that identifies those fields not at risk for pod damage or economic loss. The Southern Corn Rootworm Advisory can save you time and money as well as help you use insecticides more efficiently.

|Corn Earworm Biology and Management in Soybeans||
Corn earworm, Helicoverpa zea, is the most common and destructive insect pest of soybeans grown in Virginia. Although infestation severity varies, about one-third of our acreage is treated annually. This costs farmers 1.5 to 2 million dollars annually, and requires the application of many pounds of insecticide to crop lands. We may never eliminate this pest from Virginia soybeans, but knowledge of the biology and use of best management practices can help limit insecticide controls to those fields that meet economic threshold criteria. This publication provides current information on corn earworm biology, prediction of outbreaks, pest advisories, scouting procedures, and recently revised economic thresholds.

|Galls Made by Wasps||
Gall wasps attack primarily oak trees, and are found on roots, flowers, and acorns, but especially the leaves and twigs. Roses and brambles (blackberries and raspberries) also are attacked by gall wasps. These insects have complicated life cycles, and the galls they produce occur in an endless variety of shapes and colors. In some species, alternate generations produce distinctly different galls.

|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.

The spotted lanternfly (SLF) originates from China where its presence has been documented in detail dating as far back as the 12th century. In modern times, it was first recorded from a sample collected in Nankin, China. SLF is native to China, India, Japan, Korea, and Vietnam. In September 2014, the first detection of spotted lanternfly in the US was confirmed in eastern Pennsylvania. SLF was first found in Virginia in 2018, and is continuing its spread in our state. The geographical range is likely to expand further. It is highly invasive and can spread rapidly when introduced to new areas. This is attributed to its wide host range (more than 70 host plant species) and a lack of natural native enemies. This insect will become a pest in vineyards and fruit plantings, in residential areas, and in logging systems.

|Improving Pest Management and Pollination 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.
