Catalpa Sphinx Caterpillar | Catalpa sphinx caterpillars, also known as “Catalpa worms”, are major defoliators of catalpa, their only host. 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 activity of parasites. |

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. |

Winter Grain Mite | 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. |

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.

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.

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. |

IMPACT: Virginia Potato Disease Advisory Impact | Potatoes are a major food crop on the Eastern Shore of Virginia, with average annual cash receipts of $14 million (2011-13). |

Virginia Cotton Production Guide 2016 | Proper soil fertility management ensures sufficient nutrients for maximum cotton production. Obtaining and maintaining appropriate soil nutrient concentrations is imperative, as fertilizer inputs are the largest component of production budgets for Virginia cotton farmers. At the same time, excessive nutrient application wastes money, wastes natural resources, and can negatively impact yields and environmental quality. |

IMPACT: Virginia Winter Fruit School Impact | Tree fruits are important to the agricultural
economy in Virginia. The commonwealth
ranks sixth in the nation in apple production,
with a crop valued at more than $68 million,
and 20th in peach production, with a crop
valued at $4.5 million. Although smaller in
acreage, cherries, pears, and plums also play
an important role in some areas of Virginia.
These fruit crops are susceptible to an everchanging
array of insects, plant diseases,
and weeds, and pest management programs
are complex and knowledge-intensive. |

2017 Virginia Peanut Production Guide | The primary considerations when selecting peanut varieties are yield, grade
factors, disease, pests, and drought and heat response. A good practice is
recording for each field the variety, yield, rainfall, and disease and insect incidence
every year. This will allow producers to identify the most productive and less
problematic fields, also the most productive varieties for each field. |

Brown Marmorated Stink Bug, Biology And Management In Mid-Atlantic Soybeans | The mission of the Delaware Soybean Board (DSB), Maryland Soybean Board (MSB), and
Virginia Soybean Board (VSB) is to maximize the profitability of soybean producers in
their respective states by investing soybean checkoff funds in targeted domestic and
international research, promotion and communication initiatives. The volunteer farmer-
leaders who serve on the DSB, MSB and VSB boards of directors invest your checkoff
dollars in research to improve soybean production practices to make your farm more
profitable and ensure the sustainability of Mid-Atlantic soybean production. |
