Fascinating Leaf
Galls

Image by Seth Nagy[/caption] Pest Alert: Leaf galls In the spring you have probably noticed unusual growths and bumps on leaves, especially on maples and oaks. These protective structures are called leaf galls. They form when an insect or mite tricks the plant into protecting the pest’s developing offspring. Leaf galls are a type of abnormal plant growth, typically caused by plant growth-regulating chemicals injected by the insect during egg-laying or produced by the developing insect. Usually the growth is so distinct that the insect or mite can be identified by the resulting gall. More than 2,000 different types of gall-forming insects occur in the United States. Galls can form on any part of the plant, not just leaves. Most are formed by gall wasps, gall midges, or gall mites. Less common gall producers are aphids, psyllids, and gall flies. Some galls are formed by bacteria, fungi, and nematodes. A leaf gall associated with white oak leaves is caused by the small wasp Neuroterus saltarius. The female’s ovipositor inserts an egg into the leaves. A gall forms on the leaf’s underside around the developing wasp. Once the gall has developed, it drops to the ground, where the insect completes development. Two common galls found on maples are eye spot leaf gall and bladder leaf gall—both caused by mites. Although leaf galls don’t cause problems and insect galls can be ignored, some bacterial and nematode galls do cause problems. If you observe weak growth or stress in a plant with galls, try to identify the gall and find the right treatment. Your county Extension center can help. Otherwise, just enjoy the wonder of Mother Nature. — Seth Nagy
