|Aphids in Virginia Small Grains: Life Cycles, Damage and Control||
Four species of aphids attack small grains in Virginia -- greenbug, corn leaf aphid, bird cherry-oat aphid, and English grain aphid. In general, these aphids are small pear-shaped insects (1/16 to 1/8 inch long) that are green to nearly black, or sometimes pinkish in color. Immature aphids look just like adults except smaller. Both winged and wing-less forms can occur in the same colony. All grain aphids have a pair of conicles, tailpipe-like projections, on the top side of the tail end. Aphids feed singly or in colonies on upper and lower leaf surfaces and stems. They feed near plant bases when plants are young or during cold weather, and on upper-canopy leaves, stems, and even grain heads later in the season.

|Catalpa Sphinx Caterpillar||
Catalpa sphinx caterpillars, also known as “Catalpa worms”, are major defoliators of catalpa. 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

|Cereal Leaf Beetle, Biology and Management||
Cereal leaf beetle, a native to Europe and Asia, was first detected in Michigan in 1962. Since that time it has spread throughout most of the mid-western and eastern United States and has become a significant pest of Virginia and North Carolina small grains. This insect can become very numerous in small grain fields and the larvae are capable of reducing grain yield by eating the green leaf tissue.

|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.

|Integrated Pest Management Peanut Scouting Manual||
Integrated Pest ManagementIn 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 Three Keys to IPM

|Intensive Soft Red Winter Wheat Production||
New and successful techniques have been developed for intensive soft red winter wheat management by a multidisciplinary research and Extension team at Virginia Tech. Research was started in the early 1980's and continues today. The guidelines presented in this manual and the accompanying videotape are based on that research.

|Managing Stink Bugs in Cotton: Research in the Southeast Region||
Stink bug pests across the south eastern cotton belt consist of three main species: the brown stink bug, Euschistus servus (Say); the green stink bug, Acrosternum hilare (Say); and the southern green stink bug, Nezara viridula (L.) Due to the diverse environmental conditions across this production region, population levels of these species vary widely across seasons, states, and fields. In North Carolina and Virginia, green and brown stink bugs are the primary species, while southern green and brown stink bugs predominate in Georgia,and all three species are commonly observed in South Carolina.

|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.

|Winter Grain Mite||
Species: Penthaleus major (Dugès)
Size: Adult, 1 mm long; eggs, .25 mm long..
Color: Adult is dark brown to almost black with red legs (Figs. 1 and 2); nymph is brownish with orange legs; a young larva is bright pink to orange but darkens to light brown after one day; freshly deposited eggs are smooth, kidney shaped, and reddish orange, but within minutes become wrinkled and after several days become a straw yellow color.
Description: The adult is relatively large compared to other spider mites and is the only mite of economic importance with the anal pore (a tan to orange spot best seen with microscope, but can be seen with a hand lens) on the upper surface of the abdomen.
