2019 Mid-Atlantic Commercial Vegetable Production Recommendations
This guide lists vegetable varieties that are available and are adapted to the mid-Atlantic region, gives an overview of cultural practices, and list chemicals recommended to manage pests, diseases and weeds in vegetable crops. New varieties of vegetables are constantly being developed throughout the world. While all efforts are made to have comprehensive lists, not all varieties that are adapted will be listed.

Southeastern U.S. 2019 Vegetable Crop Handbook
New varieties and strains of particular varieties of vegetables are constantly being developed throughout the world. Since it is impossible to list and describe all of them, only some of the better performing commercial types are listed in the specific crop section, either alphabetically or in order of relative maturity from early to late. These varieties are believed to be suitable for commercial production under most conditions.

Florida Predatory Stink Bug
The Florida predatory stink bug (FPSB) is a native stink bug species in the southeastern United States. It predominately occurs in neotropical regions, but can be found as far north as Pennsylvania. This species is a natural enemy that feeds on a variety of insects including many agricultural pests (Figs. 1 & 2).

Cerceris fumipennis “The Smokey Winged Beetle Bandit”
Cerceris fumipennis is a solitary digger wasp (crabronid) native to eastern North America. It is a predator almost exclusively of adult beetles of the family Buprestidae. This wasp gathers many species of native metallic wood-boring beetles, as well as the invasive emerald ash borer, Agrilus planipennis (Fairmaire) (EAB).

Diagnosing stink bug injury to vegetables
In the mid-Atlantic U.S. vegetable crops are attacked by several different stink bug species (1). The primary pest species include: the invasive brown marmorated stink bug (BMSB), Halyomorpha halys, which has become the dominant species in most landscapes (2), brown stink bug, Euschistus servus Say, which is the most common species attacking tomatoes; green stink bug, Chinavia hilaris Say (3); and harlequin bug, Murgantia histrionica, which is primarilly a pest of brassica vegetables only (4). All stink bugs are piercing sucking feeders that insert their stylets into the fruit, pods, buds, leaves, and stems of plants.

Benefits of an Insecticide Seed Treatment for Pumpkin Production in Virginia
In recent years cucurbit growers in the Mid-Atlantic U.S. could purchase their seeds pre-treated with the neonicotinoid insecticide thiamethoxam. The insecticide seed treatment is currently packaged as FarMore F1400, which also includes three proven and complementary fungicides that provide the first line of defense against several key seed and seedling diseases including Rhizoctonia, Fusarium, Pythium, general damping-off and seedling blight.

Evaluation of the Residual Efficacy of Commercial Slug Baits
Slugs are prevalent pests in no-till and reduced-till crop systems in Virginia. These slimy mollusks utilize plant residue to hide during the day, and at night, they feed on numerous crops causing irregular feeding holes and shredded leaves. Slugs cause the most damage during early plant growth.

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 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.

Striped Cucumber Beetle
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.

History, Distribution and Pest Status of the Mexican bean beetle
Mexican Bean Beetle (MBB), Epilachna varivestis Mulsant, (Fig 1) is an herbivorous ladybeetle (Coccinellidae) that feeds on legumes in North America. It is closely related to the squash ladybeetle, Epilachna borealis, which feeds primarily on cucurbits. MBB can cause significant defoliation damage to bean crops, particularly those in the genus Phaseolus (snap beans, lima beans, pole beans, etc.). For more information on general biology and pest management of MBB, see VCE Fact Sheet No. ENTO-51.

Pepper Weevil
The pepper weevil, Anthonomus eugenii (Cano), is a sporadic pest of pepper in Virginia. The insect is predominately a pest in the southern U.S., where it can inflict significant damage to that crop. Though adult weevils may feed on numerous plant species within the family Solanaceae, oviposition and subsequent larval development is specific to plants within the genera Capsicum (peppers) and Solanum (nightshades). Individuals may live 3-4 months and there are multiple generations (often 5-8) per year. The pepper weevil is an uncommon pest in Virginia, but if it occurs, infestations can result in the loss of entire pepper crops.

Squash Bug
Squash bugs are one of the primary pests of cucurbits in the United States. Adults are typically 10 to 30 mm long, dark gray, brown or black in color with orange or brown markings on the sides of the abdomen (Fig. 1). Overwintering adults emerge from the soil, ground litter, wood piles or buildings in the spring. After feeding and mating, females deposit egg masses on the underside of leaves. Newly laid eggs are typically light pale in color, become coppery, then darker as they develop. Egg masses are commonly laid in diamond or V-shaped patterns along leaf veins (Fig 2).

Green Stink Bug
Green stink bug, Chinavia halaris (formerly Acrosternum hilare) (Say), is a highly polyphagous pest of many crops throughout Virginia including soybean, tomato, pepper, snapbean, okra, and tree fruit and nut crops. They are often confused with southern green stink bug, Nezara viridula (L.) because of their similar green coloring and habitat during the growing season, but can be properly separated by identifying the elongated scent canal on the ventral side of the metathorax. They can also be distinguished from the shape of their abdominal spine with the green stink bug having a more pointed spine at the base of the hind legs instead of the rounded spine on the southern green stink bug. Also, southern green stink bug is rarely found in Virginia.

Beet Webworms
Both Hawaiian beet webworm (HBW) and beet webworm (BW) have multiple generations per year, and the total number is based on temperature. In tropical and subtropical climates, HBW is active year round, and can complete a generation in about 30 days. The species cannot overwinter in Virginia, but can migrate northward during the season to become a pest in late summer and early fall. BW is found throughout the U.S., but is more common in the western states. This species has fewer generations per year and can overwinter in the soil as a mature larva.
