Pine sawfly is the larvae of a wasp that looks like a fly. Young larvae start out by stripping the green tissue off the vein. As they get older, then just eat the entire needle. They only eat last year's needles. They ruin the landscape value of the trees.
Bagworms hatch in Late May and are most vulnerable to sprays. As they feed on the foliage, they spin dead leaves around themselves with silken thread.
Your ash tree (s) can be protected from this insect with a trunk injection of an insecticide in the early spring.
We put out sex pheromone traps in the spring to determine when the moths are active.
If not protected, this insect kills branches of larger trees but it can kill smaller trees.
