Twig Girdlers and Dropped Twigs Horticulture and Home Pest News
By A Mystery Man Writer
Description
An occasional sight in late summer, especially in southern Iowa, is the accumulation of small broken twigs on the ground under oak, hickory and other shade, nut and fruit trees. The foliage at the ends of twigs turns brown prematurely before the twigs fall to the ground. The dropped twigs that look like they were neatly cut from the tree as with a pruning shear are the work of the twig girdler, Oncideres cingulata. Damage by the twig girdler is occasionally conspicuous. Heavily damaged trees may appear ragged and young trees can become deformed.
