|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.

|Control of Brown Marmorated Stink Bug with Insecticide-Treated Window Screens||
In Virginia and other Mid-Atlantic states, the invasive brown marmorated stink bug (BMSB) has become a serious nuisance pest (Rice et al. 2014). Each fall, these insects aggregate on buildings seeking shelters in which to spend the winter months.

|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.

|Leatherwing (Soldier) Beetles||
Beetles in the family Cantharidae are referred to as soldier beetles or leatherwings. The name soldier beetle originates from the elytra (front wings) of one of the earliest described species being reminiscent of early uniforms of British soldiers. The latter name was coined for the soft nature of the elytra. Two species in the genus Chauliognathus are commonly found in Virginia. Chauliognathus pennsylvanicus (Fig 1) is often referred to as the Pennsylvania leatherwing, or the goldenrod soldier beetle referring to its favorite flowering plant in the fall. A similar species Chauliognathus marginatus, the margined leatherwing, is found in the spring on various flowers.

|Striped Cucumber Beetle||

|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.

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 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.

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.
