Can sirex wood wasps be dangerous?

Sirex wood wasps can be dangerous to pine trees. When a female wood wasp lays eggs. It drills one to six holes into the tree, lays an egg on each hole and fills them with mucous. Usually one hole is filled with fungal spores also introduced by the female. Once the eggs hatch, the larvae tunnel into the wood and feed on the fungus. The fungus and mucous kill the tree.
