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).

|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.

|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.)

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.

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.

|Integrated Pest Management Peanut Scouting Manual||
In the competitive global peanut market, you need to lower production costs. At the same time, you also need to keep pesticide residues in peanuts to a minimum; protect rivers, streams, and lakes from runoff; and prevent chemicals from leaching through the soil to groundwater. Using IPM to protect crops only from pests that are likely to cause economic losses is a good way to meet these goals.

|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.

|Galls and Rust made by Mites||
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. Galls come in an endless variety of forms. Many are strikingly colored or curiously shaped. Each gall-making species causes a gall structurally different from all others. By noting the type of host plant and the structure of the gall, one can identify the gall-making mite without actually seeing it.

|Fall cankerworm: Alsophila pometaria||
Cankerworms are also known as inchworms, loop worms, and spanworms - this is credited to their distinctive way of moving.

This causes the abdomen area to contract and gives the worm the appearance of arching its back.
