New Bug Threatens Ash Trees

The cottony psyllid, also known as jumping plantlice, measures about one tenth of an inch. It preys on fall gold black ash and mancana ash trees.

Foresters in North Dakota have recently discovered the existence of a bug that chews on the leaves of certain types of ash trees. The cottony psyllid, or jumping plantlice, has been found in the Bismarck and Fargo areas. The bug is known for preying on fall gold black ash and mancana ash trees. Foresters say this is the first year they have seen it, though they suspect it was around last year based on the number of them that have been spotted. The bugs chew on the leaves of ash trees, leaving a white, cotton-like substance behind that causes leaves to curl up and die. Using chemicals such as insecticidal soap can kill them, though it is recommended to use chemicals right after they hatch. Foresters also recommend giving trees at least an inch of moisture a week, as trees under drought stress are more prone suffer fatally. ?EUR??,,????'??+Source: Washington Post
