Diagnosis Case: Pine
Details: A homeowner calls and says that the pines in their yard have been
attacked by something. The homeowner initially said that there are needles missing. You know that
there has been a lot of European Pine Sawfly cases this summer, but must make sure this is the correct
diagnosis.
It is your job to make
an accurate insect diagnosis for this homeowner's pines so proper control methods can be
followed. You must know first, what symptoms and signs to look for and secondly, what
questions to ask. By selecting questions below, you will be able to note the differences
in insect patterns that will help you diagnose the problem. Good Luck!

What are the kind of pine trees are affected? Do new, old, or both new and old needles show symptoms? If you see the larvae, are they found singularly or did they appear individually? |
