Of North American origin but now well established on honey locust (Gleditsia triacanthos) in various parts of Europe, including (from the s onwards) southern emerge from late May onwards. Larvae feed gregariously on the leaves, causing them to develop into yellowish-green to purplish-red, pod-like galls that eventually turn brown. Honeylocust (Bleditsia triacanthos) can be attacked by Honeylocust pod gall midge (Dasineura gledichiae). It's a tiny midge, or fly, that develops in the leaves, deforming them. They're hard to control because there are multiple generations each year, with new .
Honeylocust pod gall midge—Dasineura gleditchiae; Galls on the leaf – normally regularly shaped domes above and sometimes below the upper surface – can be caused by a number of pests and diseases. Here we are interested in the ‘midge’ that causes galls on blackcurrant leaves. Galls sometimes materialize as larges round growths. Ascending branches, dark green leaves, may have some pods. Skyline — 45 feet tall by 35 feet wide. Compact, ascending branches. Pyramidal. Dark green leaves. Sunburst — feet tall. New growth golden, changing to bright green. Needs regular irrigation. Extremely prone to Honeylocust Seed Pod Gall Midge.

Pest description and damage The honeylocust pod gall midge is a tiny orange gnat. The small bright pink maggots feed within the galls which are leaves that have become deformed, thickened, and podlike. The larvae are sheltered inside the deformed leaves.
Infested leaves may dry and drop from the tree. Honeylocust pod gall midge, Dasineura gleditschiae. This tiny fly or midge overwinters as an adult. When new growth begins, the female lays eggs in the young leaflets. Larvae hatch in one or two days and begin feeding. Their feeding causes the leaflet to become a pod-like gall that frequently dries up and drops prematurely.
Honeylocust (Gleditsia triacanthos)-honeylocust pod gall midge dasuneura gleditchiae. Pacific Northwest Insect Management Handbook. Retrieved from triacanthos-honeylocust-pod-gall-midge.
Thickened pod-like galls develop in place of leaves. In each gall are tiny gall gnat larvae. Most deformation is caused during the first flush of new growth. Shade value Honeylocust pod gall midge book reduced.
Leaves stippled or yellow with tiny Honeylocust pod gall midge book on the underside; whitish eggs and debris evident.
Infestations often confined to bases of leaflets near mid-vein. How to identify honeylocust pod gall midge. The honeylocust pod gall midge eggs are red, and laid in clusters. The larvae are cream-colored maggots, about 1/4" long. maggots live in each pod gall. Adult honeylocust pod gall midges are tiny dark flies with long slender antennae, about 1/8" long.
Honeylocust pod gall midge. Honey locust pod gall midge (Dasineura gleditchiae) is a major pest of honey locust (Gleditsia triacanthos). Feeding by the midge larvae causes leaflets of new growth to form pod like galls in which the larvae pupate.
After the adult midge emerges from the pod, the leaf tissue dies and drops prematurely. Honeylocust pod gall midge - This small fly causes leaf deformation. Repeated attacks cause death of small branches. Spider mites - The honeylocust spider mite causes the foliage to turn yellow and drop off the trees.
Cankers - Opportunistic fungi, such as Thyronectria, invade honeylocusts stressed by. Honeylocust Podgall Midge The immature stages (larvae) of a small fly, the honeylocust podgall midge, commonly cause distortions of new honeylocust growth.
Infested leaflets curl and thicken, forming small “pod galls” instead of expanding normally. Inside each pod gall, two to eight cream-colored larvae or pupae may be found. Insect issues such as Bagworm, Plant Bugs, Pod Gall Midge, Webworms, and Mites. However, these can be managed easily with finding a tree service to spray trees for insects as directed a few times throughout the year.
Overall, you can see the pros outweigh the cons for choosing a Honeylocust to include in your landscaping. Larvae of the Honeylocust pod gall midge feed on newly-emerging leaves, prohibiting them from developing normally and initiating formation of pod-like galls.
Life Cycle: There are several generations a year. The dainty adult flies become active at budbreak, laying their eggs in developing leaflets.
Xytect™ treatments will also control honeylocust pod gall midge. A Diagnostic Guide is designed to help you identify a pest issue and management solutions. Always refer to product label for all rates and approved uses.

Honeylocust Pod Gall Midge Fly. All Honeylocust species are susceptible to a destructive fly known as the Pod Gall Midge.
First, the larvae of the Honeylocust Pod Gall Midge Fly cause distortions on new Honeylocust leaflets. These distortions, or galls, make the leaflets curl up to form pods for the larvae to grow in. Honeylocust Pod Gall This gall is caused by a small fly (midge). The Sunburst cultivar appears to be very susceptible to this pest.
infested leaves have globular or pod-like distortions that contain one to several small maggots (1/4" long).
Infestations begin when females lay eggs in young leaflets. A gall-forming species that merits specific mention is the honey locust pod gall midge. This pest causes honey locust leaflets to form galls containing one to several small pinkish white maggots. Heavy infestations cause foliage to turn brown and to drop prematurely.
The young of both honeylocust plant bug and podgall midge compete for the same food early in the season – the tender new buds and leaves. This competition can be an important natural control of the podgall midge, since the plant bug kills the new growth.
Talk about a “catch 22” since it. The tree produces many pods and can be viewed as a maintenance problem. The leaflets are very small and do not pose a maintenance problem. However, they are late to leaf in the spring. Honeylocusts are also susceptible to mites, pod gall midge, plant bugs, and mimosa webworm.
The pod gall midge is an interesting critter though. Honeylocust podgall midge overwinters in the adult stage near previously infested honeylocust plantings. Adults move to emerging honeylocust buds. Eggs are laid among the emerging leaves, and the larvae feed on the leaflets, causing them to curl and thicken into the pod gall.
honey locust pod gall midge. Asked FebruAM EST. I live in the Colorado Front Range area and have five honey locust trees with varying degrees of twig damage from this midge.
I know drought can cause more problems for these trees and I wnat to treat for midges this year. The information in the extension service is from. Honeylocust pod gall midge is a small fly that lays eggs on buds in early spring. The feeding of the newly hatched maggots causes swellings to form around them for protection.
This is a fairly common pest in Utah. Heavily infested leaves drop prematurely and when small branches die back, new shoots develop. There are several generations each year.Pod gall midge causes unusual reddish galls at the tips of the branches.
The galls appear in late spring and may be most common on thornless, seedless cultivars. These have become quite a problem in many areas. Control is difficult. Spider mites cause an autumn-like yellowing of the leaves. Diagnosis of this problem is difficult due. Honeylocust pod gall midges overwinter in cocoons in the soil or bark crevices, and emerge on warm spring days.
Larval feeding causes the leaves to swell, protecting the midge larvae inside. Swellings (galls) on honeylocust leaves are fairly common in northern Utah, and are caused by a midge (Dasineura gleditchiae).
