Locust tree insects and diseases

Several Insects and mites feed on honeylocust trees in Colorado. Their feeding can cause conspicuous injuries that may make the trees unattractive. Heavy infestations can reduce tree growth rate and vigor and cause some twig dieback. However, it is extremely rare that these injuries alone permanently injure the trees Locust Insects & Diseases. Larvae tunnel in trunk and larger branches of live trees. Most damaging on younger trees during dry seasons. They attack healthy young trees boring into the heart and sapwood of stems and branches. Young larvae feeding in the spring cause bleeding at the site of the injury. Wet spots are present on the bark Several types of bacteria are associated with wetwood. When a locust tree contracts the disease, the wood will turn a yellow-brown color at the central core of the tree. This affected area will often look and feel wetter than surrounding wood and could ooze slime. Cracked wood can also occur during the wintertime if a tree has this disease

Plant identification. Honey locust trees are deciduous and grow 25 to 30 feet tall. Some have heavy pod production. There are several cultivars selected for unique growth habit or foliage color. Honey locusts leaf out late, go dormant early, and drop their leaves early in the fall The honey locust tree is most commonly used in city landscaping, as it has so many benefits. Unfortunately, over-cultivation has led to an increase in pests and diseases that affect the tree. In some areas, the tree has also become invasive to the point of being considered a weed

Honeylocust plant bug, Diaphnocoris chlorionis, causes damage when the insect's mouthparts penetrate the leaf cells and injects a toxic saliva while feeding. This toxic saliva, which helps with the uptake of plant cell contents and digestion, kills cells around the feeding site causing browning, leaf rolling, distortion, and chlorosis Becoming more familiar with potential diseases that may impact or diminish tree health is one way to accomplish this. Thyronectria canker on honey locust, for instance, is an infection that can cause undue plant stress and decline. You can learn more about it here. What is Thyronectria Canker The bagworm is a perennial insect pest of arborvitae, juniper, pine, spruce, and many other evergreen species (including Christmas trees). It also attacks certain deciduous trees such as black locust, honeylocust, and sycamore. The bagworm is most common in southern regions of Pennsylvania The honeylocust plant bug and the honeylocust leafhopper are small, green insects commonly found on the foliage of honeylocust trees during late spring. Both species are tiny, active, light green nymphs when first encountered in mid-spring. They are elongate-oval and pointed at both ends. They run rapidly about on the foliage and stems and are frequently first noticed because of the nuisance. Hazelnut, belongs to the family Corylus, which includes C. avellana (Common or European hazelnut) and the closely related species C. maxima (filbert).

GardenTech® Sevin® Concentrate Bug Killer (not for use on large trees) Locust. Large (up to 1½ inches long) dark bodied insects with wings. Young insects hatch and enter the soil, where they burrow to the roots. Immature locust suck sap from roots and adults may suck sap from young twigs The locust borer (Megacyllene robiniae) only attacks black locust trees. It's a native insect and was first found in the eastern part of the United States in natural stands of black locust trees. The locust borer caused problems in colonial times by rendering the durable black locust wood unsuitable for use as fenceposts Diseases Wetwood: Wetwood is a bacterial disease that causes the wood of a locust tree to turn yellowish brown in color and excrete a slimy substance. Locust trees affected by this disease may also experience cracked wood during the winter. Wetwood can seriously weaken the tree warping and cracking the trunk and branches Honeylocust plant bug (adult) This key pest is a plant bug that belongs to the insect family Miridae. This species is easily overlooked because the color of the nymph and adult closely resembles the new growth of the tree. The nymph looks nearly identical to the adult in color and form, except for its smaller size and shortened wing buds

Honeylocusts ( Gleditsia spp.) are widely planted as landscape trees along the Front Range. In recent years, many honeylocust canopies look thin due to fewer and smaller leaves combined with dieback of twigs and branches. Honeylocusts have experienced several stresses over the past few years - dry winters. The Locust Borer is so-named because its primary target is Black Locust trees. Mature larvae are 25 mm long and white with dark heads. Adult beetles are about 18 mm long and black with bright yellow bands across the thorax and wing covers.
