Spongy Moth Management for Homeowners | "Spongy moth (Lymantria dispar; formerly called gypsy moth), is an invasive pest of hardwood trees in forests and yards. The caterpillars prefer the foliage of oak and other shade trees, but also attack conifers. Spongy moth caterpillars can defoliate large trees during outbreaks, and most homeowners object to the numerous hairy caterpillars and their abundant droppings raining out of infested trees.
Since its introduction to Massachusetts in 1869, spongy moth has spread throughout the northeastern US, down in the mid-Atlantic, around the Great Lakes, and into Canada. Most of Virginia is generally infested with spongy moth, but it may not cause widespread defoliation every year." |

Japanese Beetle | The Japanese beetle is found throughout Virginia and in most of the Eastern United States. In regions west of the Mississippi it is found in isolated pockets. Japanese beetles were first found in New Jersey in 1916 and have spread from that point since. The Japanese beetle has been well established in Virginia since the early
1970’s. |

European Hornet | European hornets (Vespa crabo) are large, stout bodied insects. They have a painful sting, but do not appear particularly aggressive or vicious unless defending their nest. European hornets are nocturnal and attracted to lights at night. They sometimes girdle the twigs and small branches of thin-barked trees and shrubs to feed on plant sap. European hornets are frequently mistaken for the northern giant hornet, which has only been reported from a small area in Washington State or across the border in British Columbia. |

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. |

Sap Beetles | Adults are usually black or brown beetles with an oval to oblong shape. They have
clubbed or knobbed antennae and the economically important species typically measure
3–6 mm (0.12–0.24 inch) long. Some sap beetles have short wing covers that do not
cover the entire abdomen. Some species have flattened bodies while others are more
convex. Many sap beetles are a dull color, sometimes with mottling or spots. One
common sap beetle, the picnic beetle [Glischrochilus quadrisignatus (Say)], is an
attractive shiny black beetle with four yellow-orange bands or spots on the wing
covers. |

Rhubarb Curculio | 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. |

Vegetable Weevil | Adult weevils are a dull, gray-brown color, and about 6–8 mm (0.25–0.32 inch) long.
Adults are somewhat bristly in appearance due to t stout hairs and dense scales on
the body. Usually there is a set of dark diagonal markings framing a lighter colored
V-shape on the wings, but these may wear off with age. Antennae are elbowed and there
is a short, stout snout at the front of the head. |

Carpenter Ants | 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. |

Giant Resin Bee | Size: about 0.75 inch (1.9 cm) Color: Black and yellow-brown Giant resin bees are large with a
cylindrical body and large jaws. They have a dark head and abdomen with yellow-brown hair on the face, thorax, and the first segment of the abdomen behind the "waist." The wings are a transparent brown color that darkens toward the tips. Male giant resin bees have a truncated, squared abdomen while the females have a more tapered, pointed abdomen. Giant resin bees can be distinguished from bumblebees and carpenter bees by their cylindrical bodies and the appearance of their abdomens. Giant resin bees do not have hairy abdomens like bumblebees, nor
are their abdomens shiny like carpenter bees. Hymenoptera: Megachilidae Megachile sculpturalis Smith. |

Spider Mites | Spider mites (Family Tetranychidae, Order Acari) are not insects; they are closely related to spiders, harvestmen (daddy longlegs), and ticks. Unlike insects, which have six legs and three body parts, spider mites have eight legs and a one-part body. They also lack wings, antennae, and compound eyes. Individual spider mites are almost microscopic, yet when they occur in large numbers, they can cause serious damage. Dozens of species attack shade trees, shrubs, and herbaceous plants. |

Thrips | Adult thrips are small, pale-yellow insects (occasionally black) with elongated bodies, and fringed wings. Their life cycle consists of an egg, nymph, pre-pupa, pupa and an adult. The exact time required for thrips to complete their life cycle varies with species, temperature and the host plant. Western flower thrips complete their life cycle, from egg to adult, in approximately 10 days at 80° F. Adults insert eggs in leaf tissue which hatch in approximately three days. Nymphs feed for four to five days and then drop from the plant to pupate in the soil. Adults emerge after two days of pupation and begin feeding. |

Asian Longhorned Tick and Theileria Orientalis Ikeda: Current Thoughts and Understandings | This project will be used to disseminate current thoughts and understand the invasive species of Asian Longhorned Tick (ALT) and the spread of Theileria. The Asian Longhorned Tick is a new invasive species that was first found in the US in 2017 and has since spread to 19 states from the Atlantic Coast to the Southeastern region of the US. The ALT is credited with the widespread of Theileria. Theileria is a blood protozoa parasite that has had a negative impact on cattle producers across the state. This article is what we currently understand about the ALT and the spread of Theileria. |

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. |

Avoiding Fire Ant Stings | Imported fire ants (Solenopsis invicta and its hybrids) have been found in Virginia since 1989 and are an increasing concern as they expand their range in Virginia. Imported fire ants swarm and attack aggressively when their colony is disturbed. Pheromones released by fire ants quickly alert colony members to the threat, leading to a mass attack and many stings by the defending ants. Physical reactions to fire ant venom will vary with a person’s sensitivity. Some people may require medical treatment after being stung by fire ants. |

Fire Ant Management for Livestock Producers: Hayfields and Pastures | Imported fire ants (Solenopsis invicta and its hybrids) are an increasing concern for farming operations as they expand across Virginia. To slow the spread of imported fire ants, the Virginia Department of Agriculture and Consumer Services and the US Department of Agriculture have set a Federal Fire Ant Quarantine over much of the southeastern portion of the state. The FFAQ does not currently include all the localities in Virginia known to have imported fire ants and will likely be expanded in the future. |

Hybrid Fire Ants in Virginia | Native to South America, both red imported fire ant (RIFA, Solenopsis invicta) and black imported fire ant (BIFA, Solenopsis richteri) have been found in the US since the 1930s. Imported fire ants are now widespread across the southern US and have been reported in Virginia since 1989. RIFA and BIFA hybridize and produce fertile offspring in areas of the US where both species are found. The S. invicta x richteri hybrid fire ant zone in the US includes Georgia, Alabama, central Mississippi, and Tennessee. Recently in 2022, hybrid ants were detected for the first time in Virginia in Lee County and in several nearby counties in southeastern Kentucky. Hybrid fire ants are well established in eastern Tennessee as well. |
