|Common Ticks of Virginia||Jan 30, 2022||2906-1396 (ENTO-487NP)|
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.)

|Flour and Grain Beetles||Jan 12, 2022||3101-1577 (ENTO-469NP)|
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.

|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.

|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.

|Stink Bugs||Sep 16, 2022||444-621 (ENTO-517NP)|
Plants Attacked: Wax scale has well over 50 hosts, especially Japanese and Chinese hollies, pyracantha, spirea, ivy, hemlock, euonymus, and boxwood; Description of Damage: Infestations seldom kill plants directly, but seriously weaken them, reduce growth, and cause decline. Deposits of honeydew give rise to rampant growth of the black sooty mold fungus, particularly on burford and Chinese holly.
|May 6, 2020||444-622 (ENTO-376NP)|
|Magnolia Soft Scale||
Heavy magnolia soft scale infestations cause stunting of twigs and undersize leaves, visibly weakening the trees. Small trees may be killed. Large trees lose branches and tree shape may become irregular.
|Mar 31, 2020||444-623 (ENTO-360NP)|
|Twobanded Japanese Weevil||
The Japanese weevil has a long list of hosts, but is especially found on cherry laurel, broad-leaved evergreens, pyracantha, privet, barberry, euonymus, and many others. This weevil has also damaged vegetable and field crops in Virginia.
|Mar 16, 2020||444-624 (ENTO-362NP)|
|Dogwood Twig Borer||
The larvae tunnel in live twigs and feed down the center of the branch, making a long series of closely placed round holes for the exudation of frass. Periodically, the larvae cut off portions of the twig from within and continue to feed inside the twig on the green wood working their way down.

|Insect and Mite Pests of Boxwood||
Three pests, the boxwood leafminer, mite and psyllid commonly attack American and English boxwood in Virginia and cause spotting, yellowing, and puckering of leaves.

|Millipedes||Apr 10, 2019||ENTO-43NP (ENTO-317NP)|
Description of Damage: The bark becomes roughened and encrusted with scales. Branches and limbs die back and result in a rapid decline in tree vigor, occasionally resulting in the death of trees. Seriously weakened trees are common in Virginia as a result of scale populations, especially red and silver maples.

|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.

|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.

|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.

In Virginia, cucurbits are attacked by two native species of cucumber beetles, the striped cucumber beetle, A. vittatum, which is featured in this document, and the spotted cucumber beetle, Diabrotica decimpunctata howardi (Mannerheim), which is discussed in a separate fact sheet.
