Japanese Beetle treatment worked

We have a Little Leafed Linden behind the 16th green near the main road(Marvin Pearson Way).  Each season, this tree was attacked by adult Japanese beetles who loved to skeletize its leaves.  This season, the tree was treated with a systemic control product(Imidacloprid) to reduce the amount of damage since it is in a high visibility area.  As  you can see below, the control worked well this season with some slight damage at the very top.

Slight damage at the top of the tree where the beetles first were attracted to the  tree but once they began ingesting the chemical that was trans-located into the leaves, they moved to a non-treated tree.

I thought I had a picture of our tree and its damage from the past couple of year but could not locate it.  Here is a good example from the Iowa State blog.
