There's near 500 White Pine saplings after I logged our 60a 5 years ago. About 1/3 of them from 2' to 8' tall have 2"-3" white "caterpillers" or grubs with black dots defoliating the needles only on last years' growth. The remianing needles on the tender top growth are rust-color dead. ( Sorry, no pics since we're still on film....advice for an all-weather digital appreciated.)
There are too many to spray, and we're not comfortable with the chemicals anyhow. Advice ? Destroy the pines affected ? Cut off the dead leaders ? Pour cheap Bud on the affected pines ? :confused: :confused:
I've been cutting up the deseased pines, dropping them in place. The caterpillers or grubs are not on all of the eaten pines.
 
It's hard to guess without seeing them but they might be sawfly larva. Hort oil or insecticidal soap should take care of them.
