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.

Stalk Borer Dec 22, 2021 3104-1567 (ENTO-477NP)
Vegetable Weevil
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.
Mar 4, 2021 3104-1569 (ENTO-425NP)
Carpenter Ants
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.

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)
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.
Mar 19, 2020 444-216 (ENTO-353NP)
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
Mar 4, 2020 444-220 (ENTO-350NP)
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.

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.

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)
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.

Whiteflies
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)
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 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.

Fall Cankerworm
Cankerworms are also known as inchworms, loop worms, and spanworms - this is credited to their distinctive way of moving. In order to travel, a cankerworm must grab leaves or branches with its front legs and then pull the rest of its body forward. This causes the abdomen area to contract and gives the worm the appearance of arching its back.

Mexican Bean Beetle
Mexican Bean Beetle (MBB), Epilachna varivestis Mulsant (Fig. 1), is an herbivorous lady beetle (Coccinellidae) that feeds on bean crops (legumes) in North America. It is similar to the squash lady beetle, Epilachna borealis, which feeds primarily on cucurbits. MBB can cause significant defoliation damage to various bean crops particularly in the genus Phaseolus (snap beans, lima beans, pole beans, etc.). It will also feed on soybean, alfalfa, beggarweed, kudzu, and other legumes.

Soldier Beetles (Leatherwings)
This publication reviews the biology of cantharid beetles. Cantharids, known as soldier beetles or leatherwings, are commonly-encountered beetles throughout Virginia. Two species in the genus Chauliognathus are the most frequently observed; the margined leatherwing (Chauliognathus marginatus) is found during the spring and early summer, while the Pennsylvania leatherwing or goldenrod soldier beetle (Chauliognathus pensylvanicus) is active during the late summer and early fall. Both species visit a variety of wild and cultivated flowers, and they can be considered beneficial insects.

Food Safety For School and Community Gardens: A Handbook for Beginning and Veteran Garden Organizers
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.
