Poplar twiggall fly causes serious damage.

The poplar twiggall fly is often said to cause little damage to the aspen this insect attacks.

Dead Shoot as a reult of this insect

The vascular damage this insect causes can result in the death of twigs as seen in the photo to the left. 

If these galls are in the main stem of the tree, can the area damged by this insect break off?

An application of imidiclopyrid once a year will take care of this problem.
