We can't say from the photo what is making your white pine lose needles. The photo is rather blurred. Take a look at our website publication on white pines. It has a diagnostic chart and should be able to help you: http://extension.umd.edu/sites/default/files/_images/programs/hgic/Publications/HG54_IPM_Series_Pine...

If you see any of the symptoms described in the above pub, follow the instructions or get back to us.
It is also possible that the problem is not caused by an insect or disease but by the environment, which includes too much water (rainfall, poor drainage), drought, and many otherr possibilities. See our pub on some of these other options: http://extension.umd.edu/sites/default/files/_images/programs/hgic/Publications/HG86%20Common%20Abio...
