Ohia trees are dying rapidly, Why?

Note: Dutch elm proved to be caused by a beetle and willy willy were all killed by a wasp.

Knowing what fungus it is not that important.

It is like saying people attacked by sharks bleed to death. Therefore, we must focus on bleeding.

I am not discounting this new scale introduced in 2012.

Question: Are ohia more likely to be found dead around strawberry guava? If the scale which attacks strawberry guava can kill that tree, why can't this same scale transmit a fungus. I agree researchers checked to make sure the scale will not kill the ohia. What kills the ohia is ultimately the fungus. Which insect is the vector?
